How do I find a reputable roofing contractor? What type of warranty should I look for? Is it always necessary to tear off existing shingles before re-roofing? What function does shingle underlayment serve?
How do I find a reputable roofing contractor? The quality of your roofing project will largely be determined by the skill, expertise, and competence of your builder. Ripon Area Builders is proud of the following facts:
When contractors talk about asphalt shingles they are actually referring to organic felt-based shingles. Organic shingles are saturated and coated with asphalt. They offer excellent resistance to blow-off, as well as outstanding tear and nail-pull resistance. Fiber glass shingles are also asphalt shingles; the difference is that they're made on a fiber glass base. Properly sealed and correctly applied, many fiber glass shingles offer the same standards of tear and nail-pull resistance, in addition to excellent wind resistance, as their organic felt counterparts. What type of warranty should I look for? Warranties usually range from 20 to 40 years. Yet, as an increasing number of contractors and homeowners tell us, the length of the warranty is not as meaningful to them as upfront coverage in the few years following application. This is the time when, according to contractors, problems caused by defects are most likely to occur. Is it always necessary to tear off existing shingles before reroofing? There are two options available for reroofing installations. One would be to tear off the old roof before applying the new one (tear off). The second would be to lay new shingles over the existing roof (lay over). While the second choice is the less expensive of the two options, it is not necessarily always the best choice. Some advantages to tearing off the old roof before installing a new one are 1) any defects in the roof deck would be noted and repaired, 2) condensation problems in the attic would be revealed and proper designed attic ventilation could then be installed, 3) after old roof is torn off, waterproofing shingle underlayment could be installed before applying the new roof and 4) tearing off the old roof and starting with a clean deck before reroofing may result in a smoother finished roof system. What function does shingle underlayment serve? An underlayment, commonly known as roofing felt, will protect the roof deck from moisture prior to shingle application and provide a degree of back-up protection in the event water gets under roofing shingles.
