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 GAF Timberline HD 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 GAF recommended application to qualify for the GAF lifetime shingle warranty obtainable through GAF website.
I will work with you to come up with the best color for your home with GAF swatches and examples.
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.
