Felt Roofing has been around  since 1900, the mineral-faced form of asphalt-impregnated felt began to be supplied as roofing shingles cut into individual rectangles at first, then after about 1915, as strips with notches that stimulated the butts of two or three individual shingles. This form is still around today with little change except for a wider variety of colours and butt designs in the felts.
The mineral felt could be installed in a number of ways, such as: mechanical fasteners, hot asphalt, cold asphalt adhesive, non-asphaltic adhesives, heat (torch or hot air) or a combination of these. Lastly, there is often a layer of solar-reflective stones spread over the surface of the mineral felt. The presence of these stones protects the felt surface from the damaging effects of the sun’s rays.
