Besides the obvious, when the roof is leaking, a visual inspection will reveal shingles lifting at the corners and each shingle seam starts to stand out dramatically when the roof has reached the end of its life expectancy.
The average roof replacement takes place during a 1-2 day period, my canister is delivered morning of job start and the job is complete when it is removed at the end of the next day after a final walkthrough.
The standard roof should last approximately 30 years.
I primarily use Owens Corning Duration Dimensional asphalt shingles, they tend to be the most economic for the best quality.
There are a variety of causes for a roof to wear out, age primarily is the leading cause, while direct sunlight and severe winters will cause a roof to age prematurely. If your roof is a second layer (re-roof) you will never get the full 30 years out of it, they generally last about 20 years. And the most upsetting cause is improper installation.
I offer a 10-year labor warranty on all of my roof installations, and I follow the Owens Corning recommended application to qualify for the Owens Corning shingle warranty that I provide the information for upon the completion of your new roof.
I will work with you to come up with the best look for your home with Owens Corning Duration shingle swatches and samples and CertainTeed siding swatches.
This has a lot to do with the rotation of the sun and how much direct sunlight each side of the roof receives.
Yes, I can replace your roof as long as the temperature is above 20 degrees.
