How to Hire A Roofing Contractor
 A new roof is a big job. And a big investment. That's why we strongly recommend that you hire a professional roofing contractor who can offer proven experience, a written estimate and worry-free installation. To make sure you're choosing the best, use this checklist 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? Protect your home from accidental damage?
- Thoroughly inspect your roof? Including flashing chimney, soil stacks, other roof penetration, deck, plus attic?
- Provide a written estimate? Including an accurate description of the work to be performed, plus work that may have to be contracted out?
- Explain the entire roof system? Your roof is a series of components that work together; you should know all about them.
- Check existing ventilation for proper circulation? Explain the importance of ventilation? Improper ventilation will damage your shingles and can invalidate your manufacturer's warranty.
- Explain reasons for tearing off versus nailing over the existing roof? Local codes determine the maximum number of nail-overs.
- Know, explain and comply with local building codes?
- Apply underlayment to the wood deck? Additional waterproofing underlayment might be needed if ice damming, wind-driven rain, or collected or flowing water might be a problem.
- Apply shingles according to manufacturer's specifications?
- Use proper fastening techniques? Four fasteners for each shingle - six in high wind areas. Fasteners should penetrate 3/4" into the deck.
- Commit to supervise the job during all phases of work and inspect it completely when finished?
- Thoroughly clean up your roof and around your house when finished? Remove all surplus material? Leave your yard in the same shape the contractor found it?
