Cap sheet roofs, or mineral paper flat roofs, as we used to call it, is an old school heavy tar paper flat roof system with a granule that looks like colored sand, but is more comparable to tiny fired bricks on their surface. This can be glued, nailed or “torched” down and is often placed over an existing BUR flat roof surface.  This mineral surface is the same as a typical asphalt single roof on your typical home. 3 foot wide roofing sheets are tared at the bottom and nailed at the top, working their way to the highest point. These roofs are quite durable, with an average life of 16.3 years, which is seriously on a decline, life-wise, because asphalt producers continue to place more fillers, which is just dirt in their products.  This filler content is now between 40% to 60%.

Once the roof begins to fail, they are a perfect candidate for roof restoration and roof resurfacing because of the highly porous and rough surface, which provides many times the adhesion area of any other roof type. These roofs react well to acrylic if there are no drains or water pathways and the roof is well pitched. It also reacts well with silicone and SPF foam toppings.
