If your home is typical, its roof is covered with asphalt shingles, which may need to be replaced every 15 or 20 years. Temperature extremes and sunlight can crack, curl, and split the shingles. Rain and sleet wear them down. The Wind tears them.

As our clients know, we take great care in helping you select the best roofing system to meet your needs and budget and we take great care to do a wonderful job installing your roofing system.

What to Look for in Quality Roofer

Start your prospect check with availability.

Then do a drive-by inspection of a few recent jobs. Check that the spaces between individual shingle tabs, known as water gaps, line up laser-straight as they alternate shingle rows. Make sure that shingles are trimmed in a clean line along the valleys where they overlap the valley flashing. On roof ends, shingles should also be neatly trimmed so they align with the roof edge. Ragged lines mean slipshod work. Also look for neat, tar-free flashing at roof valleys and eaves.

If the roofs stand up to scrutiny, call references directly and ask them the following questions:

  • Would you use this roofer again?
  • Did the roof leak? If so, did the roofer respond promptly, was he courteous and did he charge you for any additional work?
  • Did the job come in on budget? If not, by how much did he exceed budget? Were the extra charges justified?
  • Did the roofer damage any bushes or flowers, and did he leave nails in the driveway? Flat tires are a common complaint during and after a roofing project. Good roofers pick up any dropped nails with large rolling magnets throughout the job.
  • Was a designated foreman available to address your concerns during both the tear-off and the installation of the new roof? (These jobs are sometimes done by different crews.) You want a point person for questions and concerns you have throughout the job.

When a roofer comes by to look over your job and work up a price, note his appearance. Pride extends beyond the job site. If he isn’t clean enough to sit at your breakfast table, do you really want him working on your house? Then detail the full range of your expectations. Find out who will do the work and the foreman’s name. And get everything in writing.

If you like what you see, it’s time to verify that the roofer carries workers’ compensation coverage and at least $1 million of liability insurance. Get his agent’s name and proof-of-insurance certificates. Then get an estimate, which should be free. Because roofing is a short-term job, break up the total due into two payments: one-third up front for materials, and the remainder when the roofing and cleanup are done to your satisfaction.  DNS Exterior Inc. is fully licensed and bonded.

Also insist on a warranty that covers leaks, flashing failure and other labor-related defects. A one-year warranty is a minimum, though two or three years is preferable. These same stipulations should go into the contract, which should also include what type of shingles will be used. Request the highest-rated, longest-lasting shingles you can afford.

Shingle manufacturers generally back their products for 20 to 30 years. Some warranties are void if shingles are put on over existing shingles, so tearing off the existing layer could be required, at an additional cost. Asphalt roofs last 13 years on average, so a 20-year warranty should be fine. Just be sure you get the paperwork and proof of purchase needed to pursue any problems down the road.
