Q. If I receive multiple estimates on a roof repair project, how do I know which is best?

A. If an estimate is much lower than the others and it sounds too good to be true, it probably is. Many low bids from “fly-by-night” contractors may seem attractive, but these roofers are often uninsured and perform inferior work. If you find any estimate confusing, ask for it to be broken down into items and terms that are easier to understand.

Q. What are the best asphalt shingles for my roof?

A. The performance of your asphalt shingles depends on the quality, quantity, and compatibility of its fillers, reinforcements, and surface granules. The most common types of asphalt shingles are fiberglass and organic. Fiberglass shingles are more resistant to fire and moisture while organic shingles are more wind-resistant, have a higher overall strength and can be installed in cold temperatures.

 

Additionally, asphalt shingles should always comply with American Society for Testing and Materials (ASTM) standards and applicable building codes. Fiberglass shingles should meet ASTM D 3462, (Standard Specification for Asphalt Shingles Made from Glass Felt and Surfaced with Mineral Granules) while organic shingles should meet ASTM D 225 (Standard Specification for Asphalt Shingles (Organic Felt) and Surfaced with Mineral Granules).

 

Also, remember that the length of a warranty should not be the driving factor in choosing a roofing product because the warranty does not necessarily assure complete satisfaction.

Q. What is the difference between No. 15 underlayment and No. 30?

A. For asphalt shingles, the NRCA (National Roofing Contractors Association) recommends a single layer of No. 15 asphalt-saturated underlayment for roofs with slopes of 4:12 (18 degrees) or greater. For roof slopes between 3:12 (14 degrees) to 4:12 (18 degrees), the NRCA recommends a minimum of two layers of No. 15 underlayment. If you are installing a heavier shingle with a projected longer life, a No. 30 underlayment is recommended.

Q. My house has a roof with a 2 1/2:12 (11 degrees) slope. Should I use asphalt shingles?

A. The NRCA does not recommend shingles on slopes less than 4:12 (18 degrees). Asphalt shingle roof systems rely on gravity and the slope of your roof to effectively drain any water.

Q. What is the best system for a flat roof?

A. There is no one specific roofing system that is best for all situations. Even if you are using the best materials, your roof could be improperly installed and lead to a leaky roof. Quality workmanship and attention to detail are equally as important as the type of materials used. Additionally, remember that regular maintenance plays an important role in the integrity and life of your roof.

 

Also, low-slope roofing materials manufacturers may not always offer warranties on their materials, and the only warranty you will be able to obtain is from the contractor. If you work with a professional roofing contractor such as G & B Roofing Inc., be sure to get a detailed estimate.

Q. How can I clean algae and moss from an asphalt shingle roof?

A. Algae and moss can be cleaned off using a mild solution of chlorine bleach and water. Another method is to apply mild detergent using a sponge or hand-held sprayer, and then rinse thoroughly. You should never use a power washer or a high concentration of bleach. Also, you should not scrub the surface of the shingles.
