13 QUESTIONS TO ASK BEFORE YOU HIRE A ROOFER
13 Questions to Ask When Hiring a Roofing Contractor
Basing your decision purely off recommendations or a gut feeling is risky without knowing all the facts about the contractor, so here are 13 questions to ask that will help you narrow down your selection and hire the right roofer for your project:
- Do you have adequate insurance coverage? Your roofer should carry insurance to help protect your home from accidental damage. Owens Corning Roofing Platinum and Preferred Contractors hold at least $1,000,000 in general liability insurance.
- Do you offer additional warranty* and workmanship** coverage? Your roofing contractor should be able to offer a limited warranty that may include workmanship coverage. Owens Corning Roofing Platinum and Preferred Contractors offer several different levels of Roofing System Limited Warranties that offer up to a lifetime** of material and workmanship coverage.‡
- Will you provide an explanation of my warranty? Your roofing contractor should explain your warranty and be clear about whom to call with a problem. Find out if defective shingles are replaced for prorated replacement cost or original cost and if labor charges are additional. Learn more about roofing warranties from Owens Corning.
- Which roofing materials will you use on my roof? Not all roofing products are the same, so be sure your roofer works with a name you can trust. Learn more about Owens Corning® roofing products.
- Will you provide me with a written estimate? Your roofing contractor should provide an estimate that includes an accurate description of the work to be performed, plus work that may have to be contracted out.
- Do you comply with all local building codes? Your roofer should know and comply with all local building codes.
- Could you please give me a list of references? Ask for references and call a few of them.
- Will you perform a thorough inspection? In addition to checking for storm damage, your roofing contractor should perform a thorough inspection of the entire roofing system, including the deck, attic, flashing, chimney, soil stacks, and other roof penetrations.
- Will you check for adequate ventilation? Your roofer should check the existing attic ventilation and explain the importance of proper ventilation. This should include inspecting the roof from inside the attic to determine if the current ventilation system is working properly. Improper ventilation can damage your shingles and invalidate your manufacturer’s warranty. Use our ventilation calculator to help calculate how much ventilation you will need for a healthy and balanced attic.
- Will you install synthetic underlayment? Roofers will install either a synthetic or felt underlayment as the first layer of protection on your roof deck. If you’re looking for advanced protection against leaks, water absorption, and mold then you’ll want to make sure your contractor will use a synthetic product rather than felt. Learn more about Owens Corning® synthetic underlayment products.
- Will you install ice and water barriers? Depending on several conditions, additional ice and water barriers between the shingles and the wood deck may be needed to help prevent ice damming, wind-driven rain, or collected water. Learn more about Owens Corning® ice and water barrier products.
- Will you follow the manufacturer’s specifications? Your roofer should be familiar with and follow all manufacturer’s specifications since improper application can affect your manufacturer’s warranty. Owens Corning® Roofing product specifications are available for download on all product pages and can also be found in our Document Library.
- Will you explain how my roofing system works? Your roofer should offer a thorough explanation of the entire roofing system and how all the parts work together, so you can make educated decisions.
