Beginning January 1, 2011, most of the major shingle manufacturers upgraded their warranties from 30, 40, or 50 years to a Limited Lifetime warranty. The reasons for the upgrade are: the improved shingle quality, improved wind performance (some shingles can withstand high wind speeds up to 150ph), and improved environmental impact. For more information on how you can get a new roof with a limited lifetime warranty and what the word “lifetime” means, contact ken [at] kencooperroofing [dot] com.
