Roof Repair Carrollton: Built-up Roofs and Roof Rolling
Homes with flat or low sloping roofs usually have a built up roof surface, also called a tar-and-gravel roof. Sheds, garages, and other out buildings are sometimes roofed with aspahlt roll roofing.
A built-up roof consists of several layers of roofing felt, each coated with hot or cold-mopped asphalt. The top layer is surfaced with crushed gravel or rock. These roofs generally last from 10 to 20 years, depending on the sun's intensity.
Asphalt roll rooffing, made in the same way as asphalt sningles, has a lifetime of 5 to 15 years. Sometimes, roll roofing of a matching color is used to cover the valleys of an aspahlt shingle roof.
Leaks in a flat roof are usually easy to locate-they tend to be directly above the wet area on the ceiling. Leaks may develop at flashings or where the wind has blown the gravel away to expose the surface.
Leaks are also likely where weather and wear have caused blistered asphalt, seperations between the roofs surface and the drip edge, curling or split roofing felt that's exposed, and cracks or holes in the roof material.
Repairs are the same for both built-up and roll roofing. Fill in any cracks with roofing cement. If youre repairing a blister or small hole, cut the patch you need from either a piece of roll roofing or an aspahlt shingle. Use galvanized roofing nails to secure the patch. Any hole larger than a square foot should be patched by a professional roofer.
If your roof is beyond repair and must be replaced, its best to call in a professional. Resurfacing a flat roof with layers of roofing felt and hot mopped aspahlt is beyond the scope of most home owners because of the processes and equipment involved; moreover, working with hot molton aspahlt is messy, difficult and even a very dangerous job.
