answered some frequently asked questions below but if you have one that is not covered here, feel free to call us and we will have your answer.

Question 1: I received three significantly different proposals from contractors. How should I decide which contractor to select?

Answer: Clearly, written proposals that are detailed and broken down into separate line items are a good sign that the contractor is being thorough and has prepared an accurate estimate.
The following is a partial list of items your estimate or proposal should include:
The type of roof covering, manufacturer and color.
Materials to be included in the work, e.g., underlayment, ice dam protection membrane.
The scope of work to be done
Removal or replacement of existing roof
Flashing work, e.g., existing flashings to be replaced or re-used, adding new flashing, flashing metal type
Ventilation work, e.g., adding new vents
What Type of warranty you will receive
Question 2: I received several estimates to replace my asphalt shingle roof system and the prices vary greatly.

Answer: If one estimate seems much lower than the others and it sounds too good to be true, it probably is. Many fly-by-night contractors’ below-cost bids seem attractive, but these contractors often are uninsured and perform substandard work. If an estimate is confusing, ask the contractor to break down the estimate into items/terms you can understand.

Question 3: What is the best asphalt shingle to use on my roof?

Answer: Asphalt shingle material performance depends on the quality, quantity, and compatibility of asphalt fillers, reinforcements, and surface granules. There are two kinds of asphalt shingles (based on the type of reinforcement mat used); fiberglass and organic. Fiberglass shingles are more fire- and moisture-resistant than organic shingles. Organic shingles have good wind resistance, high tear strength and can be installed in colder temperatures.

Asphalt shingles should be in compliance 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,” and organic shingles should meet ASTM D 225, “Standard Specification for Asphalt Shingles (Organic Felt) and Surface with Mineral Granules.”

Question 4: My house has a flat roof. What is the best roof system for a flat roof?

Answer: There is no one roof system that is best for all applications. Keep in mind that even if you are using the best materials, your roof system still can be installed improperly and you could end up with a leaky roof. Good workmanship and proper attention to detail (e.g., flashing and drainage issues) are just as important as material selection. Also, maintenance plays an important role in roof system integrity and service life. Also, keep in mind low-slope roofing materials manufacturers may not offer material warranties to homeowners. The only warranty you most likely will be able to obtain is from the contractor. So it is critical you work with a professional roofing contractor and get a detailed, thorough proposal.
