Technology has improved the capability of manufacturers to improve the life span of today’s shingles with more asphalt, stronger matting, UV protection, algae resistance, better sealant strips, and higher wind resistant ratings.
The most commonly used shingle in the past was the 3-tabs shingle which roughly have a lifespan of 15-20 years.
Professional grade shingles are known as architectural shingles which is an industry leading standard today. These styles of shingles offer a limited lifetime warranty and a one-time transferrable warranty upon the sale of a house.
From a professional installer standpoint, the lifespan is only as good as the installer is at installing your roof. That is why it is important to hire a professional contractor that not only is installing a name brand product but is offering an installation warranty as well. The number one reason the lifespan of a product is voided is due to poor installation. This will cause a manufacturer warranty to fault.
There are more options than just the mentioned shingles above. There are endless upgrades for a more designer look if desired.
