There are several things to look for: stains on your ceiling, leaks, age and curling of the shingles.
How long to roofs last?
Between 20 and 30 years depending on the shingle, weather, and whether or not it is properly maintained.
Can my roof be fixed?
Yes, in most cases a roof is repairable.
What type of venting is best?
The most common is the ridge vent. The turbine is also very effective.
What is the best shingle?
All major brands manufacture good shingles and provide good warranties. Owens/Corning, GAF and Certainteed are a few of the most common.
How do I know my roofer is licensed?
All roofers should carry their card with them at all times which is issued by the state they are working in.
Should shingles be nailed with a hammer?
This is the only way to properly seat the nail correctly.
Why not use air guns to install my shingles?
We do not use this process because this is the most common reason shingles fail. The gun is run by air and each time the nail is shot, the less pressure it has for the next four or five nails. Or the air pressure is too high and shoots the nail through the shingle.
Why should my insurance pay for my new roof?
If you have storm damage due to wind, hail, or trees fallen on the house, your insurance policy should pay for you to use your own contractor of choice
Why does my insurance want me to get three estimates?
You are not required to get three estimates, it is the insurance companies responsibility to get an estimate, and your choice to use who you want.
