The first thing you should know is that Limited Lifetime Warranties cover defective shingles only and do not cover normal wear from age. The terms ‘defective’ and ‘normal’ here are a bit subjective in nature, but we’ll get to this later. The second thing you should know is that Limited Lifetime Warranties cover the cost of the material only for the first 10 years, after which point any compensation will be prorated based on the age of the shingle. Just about every architectural shingle now comes with a Limited Lifetime Warranty by default.
Examples of shingle problems that should not happen and may warrant a claim:
- Cracking, peeling or buckling of shingles
- Discoloration of individual shingles or sections of your roof
- Excessive shedding of granules (some shedding is normal)
- Widespread leaking or unusual moisture problems
- Significant algae staining early in the life of the roof
It’s also worth noting that damage and wear caused by natural disasters is not covered under a warranty; this kind of damage is usually covered by your insurance company instead.
