A method of producing a roofing shingle coating asphalt from a non-coating grade asphalt feedstock includes the following steps. The non-coating grade asphalt feedstock is partially blown to lower its penetration to a first penetration that is within or close to a target penetration range of the coating asphalt, and to raise its softening point to a first softening point that is lower than a target softening point range of the coating asphalt. A wax is added to the partially blown non-coating grade asphalt to further raise its softening point to a second softening point that is within the target softening point range to produce the coating asphalt. The wax may also be added during the blowing process. Resulting roofing coating asphalt compositions may comprise a paving grade asphalt and a wax, and yet still has desirable penetration, softening point and viscosity.

A low cost method and device for diverting water away from a flat roof's low spots, thus preventing it from puddling there during a rainstorm. Such puddles, if allowed to stand, can damage a roof deck structurally. The device includes a flexible membrane, an air valve mounted thereon, and mechanical fasteners for attaching the membrane along its periphery, to both the roof deck and its existing covering. Ideally, the membrane can be heat welded, taped or glued to the roof covering and joined thereto to form an airtight seal, thus simplifying construction of inflatable barriers for the roof's low spots. For each such barrier, a membrane, sized and shaped to cover at least one low spot, substantially overlaps the latter's edges and defines, in combination with the roof covering, an air pocket which, when inflated via the air valve, causes the membrane to protrude upwardly, effectively elevating the covered spot.
