All major asphalt shingle brands are of good quality and provide good warranties.  GAF, CertainTeed, and Owens/Corning are three of the most popular brands that represent the roofing industry’s shingle standards.

The replacement time will depend on your roof’s size, type, type of damage, and current weather.  All things consider, most roofs can be replaced in a matter of days. 

All legitimate roofing contractors carry their license cards with them at all times and will show you upon request. The card is issued by the state they are licensed in.

In most cases, the ridge vent is the best solution but soffit vents and turbines can be a good option for some depending on your roof structure.

Depending on the type of shingle, weather, and proper maintenance, most roofs will last between 20 and thirty years. 

Aside from the obvious leaks or stains on your ceiling, curling shingles and granule loss are the most common signs of a shingles age. And a sure way to know it’s time to
have them replaced.
