The main thing that causes a shorter life span on a roof is the lack of maintenance. Yes a shingles lifespan can be up to 50 years but the sealant around your flashings, vent pipes, and chimney normally fail within 8-10 years causing water damage which leads to more damage.

Alot of people like to believe that getting a second layer of roofing will be less costly and it will last just as long as a tear off. Thats not the case! Us at McDaniel Roofing refuse to double layer a roof because,
1. It voids all of your warranties.
2. They always end up leaking, even after being properly installed. All the fingers point at the contractor.
3. If their is any rotted wood, it can't be replaced without tearing the old roof off.
These were just a few reasons not to double layer your roof, here is the pros and cons to double layering a roof.

We have so many people ask us how to keep their roof from getting algae on it or how to get the algae off. There a few different ways like using some algae killer and a low pressure rinse, some people have zinc strips installed. The shingles we install do not grow algae because we only use AR shingles. AR means that they are algae resistant. They look like normal shingles but they are infused with copper granules which essentially keeps the roof from getting black streaks on it, or growing any algae. Here is some more information on AR shingles.
