The answer to 'asphalt shingles warranty' is that most asphalt shingles come with a manufacturer's warranty that typically lasts between 20-50 years, depending on the quality and type of shingle. These warranties cover defects in the shingles, such as premature cracking, curling, or loss of granules. However, the warranty may be voided if the shingles were not installed properly or if the roof experiences damage from severe weather, such as high winds or hail.
It's important to review the warranty details carefully when purchasing asphalt shingles, as the coverage can vary significantly between different manufacturers and product lines. Some warranties may also have prorated coverage, where the amount of coverage decreases over time. Additionally, the warranty may only cover the cost of the replacement shingles, and not the labor required for the roof replacement.
