Commonly referred to as a Tar & Gravel roof. By today's codes it consists of the use of steep asphalt (normally type III) instead of coal-tar pitch as used by our forefathers. The type of substrate dictates the type of insulation and base sheet materials to be used, plys of felt (generally 3, 4, or 5) are installed by integrating hot asphalt between each ply installed, to build an overlapping, redundant system. This system is then flooded with more hot asphalt in order to seed the application of 400 to 600 pounds of gravel per 100 square feet (1 square). We also provide emergency mobilization during hurricanes and other natural disasters, serving the entire Gulf Coast Region as well as the Atlantic Coast. Our emergency dry-in teams are able to temporarily repair your buildings at the rate of 10,000 square feet per crew per day and more, by utilizing the SPF roofing systems.
A waterproofing membrane either granulated or smooth surfaced composed of asphalts blended with polymers and reinforced with polyester fabric or fiber glass mat. Torch down refers to the application method of using heat from the torch to melt the adhesive embedded in the material. Hot mop refers to the application method of using hot asphalt from a kettle as the adhesive.
You can select from many materials from wood shakes to clay tile to slate. But by far the most practical choice, accounting for nearly two-thirds of all re-roofing in the United States, is asphalt shingles. Asphalt shingles are named for the sticky, tarry, water-repellent substance that holds them together. They are basically large rectangular mats, about 1 x 3 feet, made of cellulose or fiberglass and impregnated or coated with asphalt. They are also coated on the bottom surface with sand, talc, and other mineral filters for stiffness and to eliminate the stickiness of the asphalt. Typically the top surface is coated with granules colored with a hard ceramic glaze. Besides adding color, the granules protect the asphalt from the suns ultraviolet rays, and their weight beefs up the shingles resistance to wind.
