Description

[Technical Field]

[0001] The present invention relates to a vertical roofing exterior structure that can minimize rainwater that attempts to seep into the interior from the flat exterior surface that serves as the rainwater flow surface, and is not subject to restrictions such as the shape of the building or the installation of exterior materials. [Background technology]

[0002] Conventionally, many roofs have been proposed that have an exterior surface that appears flat. Since this type of roofing material has a connection part of the exterior material below the exterior surface onto which rainwater flows, many methods have been proposed to prevent rainwater from seeping inside the building. In most cases, gutters are installed on the backside of the joints of the exterior materials, and the exterior materials are connected on or within the gutters, so that water seeping in from the joints flows down and is drained away through the gutters.

[0003] For example, the gutter structure described in Patent Document 1 is a structure in which a garter, which is a through member, is attached to a groove formed on the base material side, and the sides of adjacent outer enclosures are fixed within this garter with retaining clips, and a lid, plug, holder, etc. are used. Patent document 2 also describes a structure in which multiple grooves 4 are provided in a base material 2, and a gutter garter 6 is fitted into the grooves 4, with the sides of adjacent outer enclosures 8 facing the inside or top of the gutter garter 6. Furthermore, Patent Document 3 shows a structure in which a gutter member 3, which is a through member, is sandwiched and fixed between a receiving member 6 arranged below and a retaining clip member 4 arranged above, and a cap 2 is engaged with the retaining clip member 4 with the side end of the roof material 1 arranged within the gutter member 3.

[0005] However, the exterior materials such as the outer enclosures and roofing materials in the above Patent Documents 1 to 3 have gutters installed on the backside and the exterior materials are connected above or within the gutters, so in order to prevent final water leakage, installation on roofs with special shapes etc. requires careful attention, which makes design, construction, etc. time-consuming. Furthermore, although this type of gutter is intended to be installed in the direction along the flow direction, depending on the shape of the building, it is necessary to place it at an angle to the flow, which often does not match the standard water flow path.

[0006] Therefore, the present invention aims to propose a vertical roofing exterior structure that can minimize rainwater that attempts to seep into the interior from the flat exterior surface that serves as the rainwater flow surface, and is not subject to restrictions such as the shape of the building and the installation of exterior materials. [Means for solving the problem]

[0007] The present invention has been proposed in view of the above, and provides an exterior structure including a connecting portion between a fitting portion formed on a side edge of a face plate portion and a fitting-receiving portion formed on the side edge of the face plate portion, wherein the fitting-receiving portion has a fitting portion formed by folding the side edge of the face plate portion downward and inward, and a groove-like portion extending downward and outward from the fitting portion, and the fitting portion has a hanging portion hanging down on the back surface side and a locking portion extending upward and outward from the lower end of the fitting portion, and the fitting portion is assembled by fitting into a fitted portion of a holding member, and the locking portion is fitted into the fitting portion, and spaces are formed between the hanging portion and an inner wall and an outer wall of the groove-like portion, respectively. In this structure, a first exterior material is used in which the insertion portions are provided on both side edges of a first face plate portion, and a second exterior material is used in which the insertion receiving portions are provided on both side edges of a second face plate portion, and the first exterior material and the second exterior material adjacent in the left-right direction are alternately arranged and connected so that the respective face plate portions form a single surface. The present invention relates to a vertical roofing exterior structure characterized by the above.

[0010] Furthermore, the present invention also proposes a vertical roofing exterior structure characterized in that adjacent connecting portions on the left and right are connected with drainage members and the holding members disposed on the back sides thereof. [Effects of the Invention]

[0011] In the vertical roofing exterior structure of the present invention, the insertion portion and the insertion receiving portion are each attached to the insertion portion of the retaining member, and without using a cover material or the like, the tip (top end) of the groove portion formed between the hanging portion of the insertion portion and the locking portion and the tip (top end) of the groove-shaped portion formed in the insertion receiving portion form a connection portion facing opposite directions (the entrances to the rainwater entry path are separated), thereby minimizing rainwater that attempts to seep into the interior from the flat exterior surface. In particular, spaces are formed between the hanging portion of the fitting portion and the inner and outer walls that form the groove-like portion of the fitting-receiving portion, so that interfacial tension acts on rainwater and prevents it from being pulled upward. Furthermore, the exterior structure uses a first exterior material having the insertion portions provided on both side edges of the first panel portion, and a second exterior material having the insertion receiving portions provided on both side edges of the second panel portion, and the first exterior material and the second exterior material that are adjacent in the left-right direction are arranged and connected alternately so that the panel portions of each form a single surface. Therefore, it is only necessary to use two types of vertically laid exterior materials, and it is possible to combine parallel materials and tapered materials, or to combine exterior materials of different widths, making it possible to create roofs with special shapes and an exterior with enhanced design.

[0014] Furthermore, when the adjacent connection parts on the left and right are connected with a drainage member and the retaining member arranged on their back sides, the drainage member can prevent rainwater from entering the interior of the room, allowing it to flow down and be drained to the water below.

DETAILED DESCRIPTION OF THE INVENTION

[0016] The vertical roofing exterior structure of the present invention is an exterior structure that includes a connection portion between an insertion portion formed on the side edge of a panel portion and an insertion receiving portion formed on the side edge of the panel portion, and the insertion receiving portion has an insertion portion formed by folding the side edge of the exterior material downward and inward, and a groove-like portion extending downward and outward from the insertion portion, and the insertion portion has a hanging portion hanging down on the back side and a locking portion extending upward and outward from its lower end.

[0017] The vertical roofing exterior structure includes a connection portion between the insertion portion and the insertion receiving portion, and is assembled by fitting the insertion portion of the insertion receiving portion into the fitted portion of the holding member, and the locking portion of the insertion portion into the insertion portion, and is characterized in that spaces are formed between the hanging portion and the inner wall and outer wall of the groove-shaped portion.

[0018] At the side edge where the fitting-in receptacle is formed, rainwater from the panel portion is guided through the fitting portion to the groove-shaped portion, so by making the exterior wall particularly high (raising the upper end of the exterior wall), rainwater that tries to seep into the interior from the panel portion (exterior surface) can be suppressed. At the side edge where the insertion portion is formed, rainwater from the panel portion is guided into the groove portion formed by the hanging portion and the locking portion, and this groove portion is located within the groove-shaped portion, i.e., located above the groove-shaped portion.Therefore, even if rainwater seeps in beyond the upper end of the locking portion, the groove-shaped portion can prevent the rainwater from seeping into the inside of the room.

[0019] The exterior material forming this vertical roofing exterior structure may be one type or two or more types in combination. In the case of one type, the illustrated embodiment ( Reference example ) the fitting portion is provided on one side edge of one face plate portion, and the fitting receiving portion is provided on the other side edge. In addition, when two or more types of exterior materials are used to form this vertical roofing exterior material, the illustrated embodiment ( Example 1 ) At least a first exterior material is used in which the insertion portions are provided on both side edges of a first panel portion, and a second exterior material is used in which the insertion receiving portions are provided on both side edges of a second panel portion. This exterior material (vertical roofing exterior material) is formed from known metal materials, etc., and is formed (molded) by roll forming, press forming, or a combination of both. There are no particular limitations on the thickness of the material, but it is generally about 0.4 to 1.6 mm.

[0020] As described above, the fitting portion has a hanging portion that hangs down toward the back surface and a locking portion that extends upward and outward from the bottom end of the hanging portion. This locking portion fits into the fitting portion of the fitting receiver. It is also desirable to provide a covering portion that folds back toward the back surface, as in the illustrated embodiment described below. Furthermore, spaces are formed between the hanging portion and the inner and outer walls of the groove-like portion of the fitting receiver. These spaces serve to prevent contact (proximity) between the hanging portion and the inner and outer walls, thereby preventing rainwater from rising due to interfacial (capillary) tension.

[0021] As described above, the fitting-receiving portion has a fitting portion formed by folding the side edge of the face plate portion downward and inward, and a groove-like portion extending downward and outward from the fitting portion. This fitting portion is fitted into the fitted portion of the holding member, so it may be formed in any shape depending on the shape of the holding member (fitted portion). Furthermore, it is desirable that the fitting-receiving portion also have a stepped portion that is folded down toward the back side in a stepped manner, as in the illustrated embodiment described below. Furthermore, if a covering portion is provided on the insertion portion and a stepped portion is provided on the insertion receiving portion, and the covering portion is arranged so as to overlap the stepped portion, it is possible to prevent rainwater from entering the interior of the room when there is heavy rainfall (heavy rain) on the exterior surface (panel portion).

[0022] The panel portion has the insertion portion or the insertion receiving portion formed on its side edge, and is a flat portion formed horizontally, as in the illustrated example described below, which can form a roof whose exterior surface appears flat after construction, but is not particularly limited to this. The same applies to the first face plate portion of the first exterior material and the second face plate portion of the second exterior material.

[0023] The retaining member forming this vertical roofing exterior structure is a member having a fitted portion into which the fitting portion of the fitting receiving portion is fitted, and may be a continuous through member that is continuous in the flow direction, or may be a plurality of members of a predetermined length that are arranged at predetermined intervals in the flow direction. Furthermore, as in the illustrated embodiment described later, it is desirable that the retaining member be arranged on the back side of the connecting portion in a state where it is arranged inside the drainage member. This retaining member is a component that has an attachment portion for attaching to the base (construction surface) and the mating portion, and may be an extrusion molded product made of aluminum or hard resin, a pressed product made of plated steel plate, stainless steel plate, or the like, or a molded body made of ceramic, etc.

[0024] The drainage member is primarily a continuous material in the flow direction, but may also consist of multiple members that can be connected in the flow direction, and it is desirable to arrange it together with a retaining member as described above, thereby preventing rainwater from entering the interior of the room through the connected parts. As for this drainage member, it is desirable that it be formed in a gutter shape as in the illustrated embodiment described later, and be formed in a substantially W-shape with a raised fixing portion provided in the center. The drainage member may be made of a known metal material or the like, similar to the exterior material, or may be made of a different material.

[0025] Furthermore, when the adjacent connection parts on the left and right are connected with a drainage member and the retaining member arranged on their back sides, the drainage member prevents rainwater from entering the interior of the room, allowing it to flow down and be drained reliably to the water below.

[0026] In this way, in the vertical roofing exterior structure of the present invention, in principle, the fitting portion and the fitting-receiving portion are each attached to the fitting portion of the holding member, and without using a cover material or the like, the tip (top end) of the groove portion formed between the hanging portion of the fitting portion and the locking portion and the tip (top end) of the groove-shaped portion formed in the fitting-receiving portion form a connection portion facing opposite directions (the entrances of the rainwater intrusion path are separated), thereby minimizing rainwater that tries to seep into the interior from the flat exterior surface. And when a drainage member is used as described above, the drainage member, in addition to the double groove described above, further reliably prevents rainwater from seeping in. [Example]

[0027] The present invention shown in FIG. Reference example The vertical roofing exterior structure is a structure formed using an exterior material 1, which is a vertical roofing exterior material in which an insertion portion 12 is formed on one side edge (the left side in the figure) of a flat face panel portion 11 shown in Figure 1(b) and an insertion receiving portion 13 is formed on the other side edge (the right side in the figure). The exterior material 1 is formed (molded) by roll forming, press forming, or a combination of both, and the material thickness is approximately 0.4 to 1.6 mm. Reference numeral 1b denotes a backing material attached to the back surface of the face plate portion 11.

[0028] The exterior material 1 is formed (molded) by roll forming, press forming, or a combination of both, and the material thickness is approximately 0.4 to 1.6 mm. Reference numeral 1b denotes a backing material attached to the back surface of the face plate portion 11.

[0029] As shown enlarged in Figure 1(c), the fitting portion 12 has a hanging portion 121 hanging down toward the back surface side and a locking portion 122 extending outward from the lower end of the hanging portion 121. Furthermore, a covering portion 14 is formed at the upper end of the fitting portion 12 by folding back the side edge of the face plate portion 11 toward the back surface side. The locking portion 122 is shaped so that it exerts an elastic force outward after installation. In addition, reference numeral 16 in the drawing indicates a groove portion formed by the hanging portion 121 and the locking portion 122.

[0030] 1(d), the fitting receiver 13 has a fitting portion 131 formed by folding the side edge of the face plate portion 11 downward and inward, and a groove portion 132 extending downward and outward from the fitting portion 131. Furthermore, a step portion 15 is formed at the upper end of the fitting portion 131, which is bent downward in a step shape toward the back surface side. In the drawings, reference numeral 133 denotes a downward piece extending downward and outward from the fitting portion 131, reference numeral 134 denotes an upward piece extending upward and outward from the downward piece 133, and reference numeral 135 denotes an expanding piece extending further upward and outward from the upper end of the upward piece 134. Of these, the downward piece 133 forms the inner wall of the groove-shaped portion 132, and the upward piece 134 forms the outer wall of the groove-shaped portion 132.

[0031] The retaining member 2, which has the mating portion 24 into which the mating portion 131 of the fitting receiving portion 13 is mated, is an aluminum extrusion molded product formed symmetrically with an S-shape attached to the left and right of an H-shape as shown in Figure 2(a), and is a piece material in which both ends of the bottom piece 21 are bent upward and the side piece portions 22, 22 are raised upward at approximately the center to form a flat fixing portion 23. In the drawing, reference numeral 221 denotes a curved receiving portion formed by extending the upper end of the side piece portion 22 outward in a fan-out shape, reference numeral 25 denotes an elastic water-stop material attached to the back surface of the flat fixing portion 23, and reference numeral 26 denotes a protruding piece provided on the inner surface of the flat fixing portion 23. The fitted portion 24 denotes a portion formed below the protruding pieces 27 that protrude downward and outward from the upper end of the flat fixing portion 23.

[0032] this Reference example The drainage member 3 used in the vertical roofing exterior structure is a symmetrical gutter-shaped member that is fixed to the back side of the connecting parts (12, 13) of the exterior materials 1, 1 together with the holding member 2 using fasteners, and is shaped in a roughly W-shape as shown in Figure 2(b), allowing rainwater from the connecting parts (12, 13) to flow downward in the direction of flow and preventing it from seeping inside the room. This drainage member 3 is formed (molded) by roll forming, press forming, or a combination of both, just like the exterior material 1, and its material thickness is molded to be approximately 0.4 to 1.6 mm. In the figure, symbol 31 denotes a bottom portion placed on the base 5, symbol 32 denotes a side portion formed by raising both side edges of the bottom portion 31 upward, symbol 33 denotes a raised fixing portion formed by raising approximately the center of the bottom portion 31 upward, and symbol 321 denotes a water-repellent portion formed by bending the upper end of the side portion 32 inward.

[0033] The dotted lines in these figures indicate fasteners such as long screws that are driven in from above. When these retaining member 2 and drainage member 3 are assembled so that the flat fixing portion 23 of the retaining member 2 covers the raised fixing portion 33 of the drainage member 3 as shown in Figure 2(c), the fastener is driven in from above the flat fixing portion 23, penetrating the raised fixing portion 33 of the drainage member 3, and its lower end reaches the base 5, thereby securing it in place. The base 5 is constructed by laying a sheathing board made of cemented wood wool board or the like on a frame (not shown) such as a main house, and then laying asphalt roofing on top of that.

[0034] Also, this Reference example The vertically roofed exterior structure uses an insulating material indicated by the symbol 4, which has a constant height (thickness) approximately the same as that of the drainage member 3 and is arranged on the back side of the panel portion 11 of the exterior material 1. This heat insulating material 4 is disposed between adjacent drainage members 3, 3 when the holding member 2 and the drainage member 3 are attached as described above, and plays a role in supporting the back surface of the exterior material 1 and keeping the exterior surface horizontal.

[0035] Constructed from these components Reference example In the vertical roofing exterior structure, the insertion portion 12 and the insertion receiving portion 13 are each attached to the insertion receiving portion 24 of the retaining member 2, and without using a cover material or the like, the tip (upper end) of the groove portion 16 formed between the hanging portion 121 and the locking portion 122 of the insertion portion 12 and the tip (upper end) of the groove-shaped portion 132 formed in the insertion receiving portion 13 form connection portions (12, 13) facing opposite directions (the entrances to the rainwater entry path are separated), thereby minimizing the amount of rainwater that tries to seep into the interior from the flat exterior surface. In particular, as shown in Figure 1(e), spaces 132a and 132b are formed between the hanging portion 121 of the fitting portion 12 and the inner wall 133 and outer wall 134 that form the groove-shaped portion 132 of the fitting-receiving portion 13, respectively, so that interfacial tension acts on rainwater and prevents it from being pulled upward.

[0036] Also, this Reference example In this case, an exterior material 1 is used in which the insertion portion 12 is provided on one side edge of one panel portion 11 and the insertion receiving portion 13 is provided on the other side edge, so that adjacent exterior materials 1, 1 in the left-right direction are connected so that the panel portions 11 of each form a single surface, and since only one type of vertically laid exterior material needs to be used, management of the components is easy.

[0037] Furthermore, this Reference example In this case, a covering portion 14 is provided on the insertion portion 12, and a stepped portion 15 is provided on the insertion receiving portion 13, and when they are connected, the covering portion 14 is arranged to overlap the stepped portion 15, so that it is possible to prevent rainwater from entering the interior of the room when there is a large amount of rainfall (heavy rain) on the exterior surface (panel portion 11).

[0038] Like this Reference example The vertical roofing exterior structure has a high level of watertightness by forming a plurality of water-stopping means, namely, the stepped portion 15, the covering portion 14, the groove portion 16 (space portion 132a), the groove-shaped portion 132, and the space portion 132b.

[0039] Also, this Reference example In the example, curved receiving portions 221, 221 are provided on the left and right sides of the holding member 2 to support the backside of each face plate portion 11 (backing material 1b), so that each face plate portion 11 is stably supported. That is, most of the face plate portions 11, 11 of the exterior packaging material 1, 1 are supported on their backsides by the heat insulating material 4, but above the holding member 2, they are stably supported by the curved receiving portions 221, 221.

[0040] Furthermore, this Reference exampleAs described above, the retaining member 2 and the drainage member 3 are fixed to the base 5 using fasteners (long screws, etc.) shown by dotted lines, but the elastic water-stopping material 25 interposed between the flat fixing portion 23 and the raised fixing portion 33 prevents rainwater from entering from the surface side, ensuring stable installation. Also, this Reference example As described above, the locking portion 122 is formed so that it exerts an elastic force outward after installation, so that it is securely locked into the fitting portion 131 and elastically abuts against the downward piece (inner wall) 133 of the groove-shaped portion 132, resulting in a higher level of watertightness. In addition, the holding member 2 is formed in advance so that the distance between the left and right protrusions 26, 26 is slightly larger than the width of the raised fixing portion 33 of the drainage member 3, so that the holding member 2 can be attached to the drainage member 3 at a predetermined position. can. [Example]

[0041] The present invention shown in Figs. 3(c) and 3(d) Example 1 The vertical roofing exterior structure is an example of using two types of exterior materials 6, 7, namely, a first exterior material 6 shown in FIG. 3(a) and a second exterior material 7 shown in FIG. 3(b). In terms of using the holding member 2 and the drainage member 3, Reference example It is exactly the same as: However, the above Reference example In this case, the joint width is small (narrow), Example 1 By using a larger (wider) joint width, a different exterior design is created.

[0042] The first exterior material 6 is a vertically-roofed exterior material having insertion portions 62, 62 formed on the left and right side edges of a flat first panel portion 61, and symbol 6b is a backing material attached to the back surface of the first panel portion 61. The second exterior material 7 is a vertically-roofed exterior material having fitting receiving portions 73, 73 formed on the left and right side edges of the flat second panel portion 71, and symbol 7b is a backing material attached to the back surface of the second panel portion 71. The first sheath material 6 and the second sheath material 7 are Reference exampleAs with the exterior material 1 in the above, it was formed (molded) by roll forming, press forming, or a combination of both, and the material thickness was molded to about 0.4 to 1.6 mm. At connection portion A shown in Figure 3(c), the second exterior material 7 is arranged on the left side of the holding member 2 and the first exterior material 6 is arranged on the right side, and at connection portion B shown in Figure 3(d), the first exterior material 6 is arranged on the left side of the holding member 2 and the second exterior material 7 is arranged on the right side.

[0043] Also, this Example 1 The vertical roofing exterior structure also Reference example Similarly, an insulating material (not shown) having a constant height (thickness) similar to that of the drainage member 3 is used, and is arranged on the back side of the first exterior material 6 and the second exterior material 7 (of their face plate portions 61, 71). This heat insulating material is Reference example When installing the retaining member 2 and the drainage member 3, such as the insulating material 4, it is arranged between adjacent drainage members 3, 3, and plays a role in supporting the back surfaces of the first exterior material 6 and the second exterior material 7, thereby maintaining the exterior surfaces (panel portions 61, 71) flush and horizontal.

[0044] Constructed from these components Example 1 In the vertical roofing exterior structure, the insertion portion 62 and the insertion receiving portion 73 are each attached to the insertion receiving portion 24 of the retaining member 2, and without using a cover material or the like, the tip (upper end) of the groove portion 66 formed between the hanging portion 621 and the locking portion 622 of the insertion portion 62 and the tip (upper end) of the groove-shaped portion 732 formed in the insertion receiving portion 73 form connection portions (62, 73) facing opposite directions (the entrances to the rainwater entry path are separated), thereby minimizing the amount of rainwater that tries to seep into the interior from the flat exterior surface. Especially this Example 1 But the above Reference example Similarly, spaces 732a and 732b are formed between the hanging portion 621 of the fitting portion 62 and the inner wall 733 and outer wall 734 that form the groove portion 732 of the fitting receiving portion 73, respectively, so that it is possible to prevent the rainwater from being pulled up by the interfacial tension. Example 1The above-mentioned waterproofing effect at connection part B is shown in FIG. 3(e), but the same is true at connection part A.

[0045] Also, this Example 1 is an exterior structure that uses a first exterior material 6 having fitting portions 62 on both side edges of a first panel portion 61, and a second exterior material 7 having fitting receiving portions 73 on both side edges of a second panel portion 71, and the first exterior material 6 and the second exterior material 7 that are adjacent in the left-right direction are arranged and connected alternately so that the respective panel portions 61, 71 form a single surface. Therefore, it is only necessary to use two types of exterior materials 6, 7, and it is possible to combine parallel materials and tapered materials, and to combine exterior materials of different widths, making it possible to create roofs with special shapes and an exterior with enhanced design.

[0046] Furthermore, this Example 1 The holding member 2 used in the present invention is formed symmetrically, so that the fitting portions 24, 24 formed on the left and right sides are effectively utilized. Reference example Similarly, only the fitted portion 24 on the right side of the holding member 2 is used, and in the connection portion B shown in FIG. 3(d), only the fitted portion 24 on the left side of the holding member 2 is used. In addition, the above Reference example In this case, only the right mating portion 24 is used, and the unused left mating portion 24 is not necessary. Example 1 In this case, the left and right mating portions 24, 24 are effectively utilized. Reference Example, Example 1 The left-right symmetrical holding member 2 is effective as a member that can be applied to both of the above.

[0047] Also, this Example 1 The drainage member 3 used in the present invention is also formed symmetrically, but it does not necessarily have to be symmetrical as long as it can accommodate the holding member 2. Reference Example, Example 1 It can be used as a component that can be applied to both.

[0048] Furthermore, this Example 1However, a covering portion 64 is provided on the fitting portion 62, and a stepped portion 75 is provided on the fitting receiving portion 73, and the covering portion 64 is arranged so as to overlap the stepped portion 75 when they are connected, so that it is possible to prevent rainwater from entering the interior side when there is a large amount of rainfall (heavy rain) on the exterior surface (panel portions 61, 71).

[0049] Also, this Example 1 However, curved receiving portions 221, 221 are provided on the left and right sides of the holding member 2 to support the backsides of the face plate portions 61 (backing material 6b), 71 (backing material 7b), so the face plate portions 61, 71 are stably supported. In other words, the face plate portions 61, 71 of the two types of exterior materials 6, 7 are mostly supported on their backsides by a heat insulating material (not shown), but are stably supported above the holding member 2 by the curved receiving portions 221, 221.

[0050] this Example 1 Even with the vertical roofing exterior structure, Reference example Similarly, in both connection portion A and connection portion B, high watertightness can be achieved by configuring multiple water-stopping means, namely, stepped portion 75, covering portion 64, groove portion 66 (space portion 732a), groove-shaped portion 732, and space portion 732b.

[0051] The exterior material 6" shown in Figure 2(d) is a member formed in a cap shape by adjusting the width dimension of the face plate portion 61 of the first exterior material 6 to be shorter, and is exactly the same as the first exterior material 6 in that it has fitting portions 62 formed on both the left and right sides, and therefore the same reference numerals are used in the drawings and the description thereof is omitted. The exterior cladding material used in the present invention has an extremely simple shape and configuration, so that the working width can be easily adjusted like this exterior cladding material 6", and the working width can be easily adjusted to accommodate various roof surfaces.
