How to choose a Reputable Contractor

Before you sign a contract, does the roofing contractor:

• Have a good reputation? Check for references and call a few of them.

• Have adequate insurance coverage? Get a copy of their current Workers Compensation Certificate and General Liability Insurance Policy.

• Thoroughly inspect your roof? Including deck, flashing, chimney, soil stacks and other roof penetrations.

• Provide a written estimate? Including an accurate description of work to be preformed and work that may be contracted out.

• Explain the entire roofing system? Your roof is a series of components that work together, and you should understand all of them.

• Check existing ventilation for proper circulation? Explain the importance of proper ventilation? Improper ventilation may damage your shingles and can invalidate your shingle warranty.

• Explain reasons for tearing off versus nailing over the existing roof? Local codes determine the maximum number of nail-overs.

• Apply underlayment to the wood deck? Additional waterproofing underlayment might be needed if ice damming, wind driven rain, or collecting of flowing water might be a problem.

• Use proper fastening techniques? Four fastenings are required for most shingles, six in high wind areas. Fasteners should penetrate ¾” into the deck.

• Thoroughly clean up your roof and around your house when finished? Your yard and home should look the same as the contractor found it.

• Clearly explain both the workmanship and manufacturer's warranty? Are defective shingles replaced for prorated replacement cost, or original cost, with labor additional? You should be very clear about whom to call with a problem.

• Use quality roofing materials? Check the product warranty plus UL fire and wind-resistance ratings. Choose a name you trust. Not all shingles are the same.

• Know, explain and comply with local building codes?

• Apply shingles according to the manufacturer’s specifications?

• Commit to supervising the job during all phases of work and to inspecting it completely when it's finished?

• Offer any additional warranty coverage?
