Underlayment roofing material with a high coefficient of friction and methods thereof

Abstract

A sheet material (e.g., underlayment roofing material) is disclosed having a high coefficient of friction and being fabricated from at least one structural layer and at least one laminated layer. The structural layer can be constructed of a woven product that can include loom fibers that may be twisted, can include a heavier strain material, and / or can include any material and / or method that creates a raised structure (e.g., raised area, raised line, etc.) in the structural layer's weave. Subsequently, these raised structures in the structural layer's weave can create small squares, lines, and / or other designs in the underlayment roofing material that provide increased friction and / or traction.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to U.S. Provisional Patent Application No. 61 / 775,920, filed Mar. 11, 2013, the content of which is incorporated herein by reference in its entirety.FIELD[0002]The present invention generally relates to a multi-layer underlayment roofing material having at least a portion with a high coefficient of friction.BACKGROUND[0003]Until the twenty-first century, residential sloped roofs typically received asphalt-saturated felt building paper underlayment that functions as, amongst other things, a secondary weather barrier. Substantially mimicking the attributes of asphalt-saturated felt building paper underlayment, synthetic roof underlayment now available can serve substantially the same function as a secondary weather barrier with better resistance to, for example, tearing, moisture, and / or ultraviolet rays than traditional asphalt-saturated felt building paper underlayment.[0004]Recent natural disasters and su...

AI Technical Summary

Benefits of technology

The patent describes a special roofing material made up of a weave with raised structures that provide increased friction and prevent moisture from collecting on it. The raised structures are made from strong ribbon material coated with resin, and the weave minimizes the size of openings. Additionally, the roofing material has a tacky surface or coating that further increases its coefficient of friction. This special material is useful for roofing buildings and provides better protection against water damage.

Problems solved by technology

With limited resources, in some instances, contractors triaged homes by repairing the critical components and installing synthetic underlayment as temporary roofing.

Some progress has been made in this area with synthetic underlayment, but the surface of synthetic underlayment can still be slick in certain applications.

For example, if the synthetic underlayment gets wet, e.g., from rain or morning dew, the surface of the underlayment can become slippery and present a hazardous condition.
