Frequently asked questions 

  • What will a new roof system cost?

    The price of a new roof system varies depending on materials selected, contractor doing the work, home or commercial, location of the home or building, local labor rates, and time of year. To get a good idea of price for your roof system, we recommend that you receive three or four proposals from contractors in your area with great reviews. Keep in mind that price is only one factor, as the quality of the materials and workmanship.


    For each roofing material, there are different grades and corresponding prices. There also are a variety of styles and shapes. You need to look at the full product range and make a choice based on your budget and needs.


    Within the roofing profession, there are different levels of expertise and craftsmanship. Insist on a contractor who is committed to quality work that can provide you referrals and testimonials. 

  • I received several estimates to replace my asphalt shingle roof system and the prices vary greatly.

    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 low quality work. If an estimate is confusing, ask the contractor to break down the estimate into items/terms you can understand.

  • My contractor is offering a one-year warranty on my asphalt shingle roof system-is that the industry standard?

    Before answering the question, a clarification needs to be made about the different warranties you will come across during your roofing project. First, there will be an asphalt shingle manufacturer's warranty. In general, this warranty covers defects in the manufacture of the shingle. The period of coverage can range from 20 years to a lifetime. Please read NRCA's consumer advisory bulletin addressing roofing warranties for more information. Once the project is complete, be sure the contractor provides you with a certificate for your records.


    Second, the roofing contractor will provide you with a warranty on his workmanship. Typically, this will cover installation and related issues. The warranty should contain what items are covered and what will void them. Many contractors offer one year or two years of coverage; however, there is no industry standard.

  • My contractor re-used the existing flashings on my roof and after he finished installing the new shingles, he left! I've left several messages with the company and no one will come back to install new flashings. Shouldn't that be included in the work?

    If the contract didn't specify the installation of new flashings, it wasn't included in the original scope of work. Be sure that all items of work to be done are included in the contract before signing it.

  • How long can I expect my roof system to last?

    Most new roof systems are designed to provide useful service for about 20 years. Some roof system types, such as slate, clay tile, and certain metal (e.g., copper) systems, can last longer.


    The actual roof system life span is determined by a number of factors, including local climatic and environmental conditions, proper building and roof system design, material quality and suitability, proper application and adequate roof maintenance.


    Roofing product manufacturers offer a variety of warranties on their products. Take a close look at those warranties to see what responsibilities and financial obligations manufacturers will assume if their products fail to reach their expected lives.

  • My roof leaks. Do I need to have it replaced completely?

    Not necessarily. Leaks can result from flashings that have come loose or a section of the roof system being damaged. A complete roof system failure, however, generally is irreversible and a result of improper installation, poor choice of materials, or the roof system installation is inappropriate for the home or building.
