Will Cleaning My Roof With Bleach Void My Shingle Manufacturer’s Warranty?

Maintaining a clean roof is essential for the longevity and appearance of your home, but it’s crucial to use the right cleaning methods to avoid damaging your shingles and voiding your manufacturer’s warranty. One common question homeowners ask is whether cleaning their roof with bleach will void their shingle warranty. Let’s take a closer look at the warranties of major asphalt shingle manufacturers in the United States.

COMMON SHINGLE MANUFACTURER’S WARRANTY

1. GAF: GAF’s limited warranty states that damage caused by improper cleaning methods, such as using bleach, is not covered under the warranty.
2. Owens Corning: While Owens Corning’s warranty does not specifically mention bleach, it does state that damage caused by improper maintenance or cleaning is not covered.
3. CertainTeed: CertainTeed’s warranty explicitly states that damage caused by improper cleaning methods, including the use of bleach, is not covered under the warranty.
4. Atlas Roofing: Atlas Roofing’s warranty does not explicitly mention bleach, but it does exclude coverage for damage caused by improper maintenance or cleaning.
5. IKO: IKO’s warranty does not specifically mention bleach, but it does state that damage caused by improper maintenance or cleaning is not covered.
6. Malarkey Roofing Products: Malarkey’s warranty does not explicitly mention bleach, but it does exclude coverage for damage caused by improper maintenance or cleaning.
7. TAMKO Building Products: TAMKO’s warranty does not specifically mention bleach, but it does state that damage caused by improper maintenance or cleaning is not covered.
8. PABCO Roofing Products: PABCO’s warranty does not explicitly mention bleach, but it does exclude coverage for damage caused by improper maintenance or cleaning.

While not all manufacturers explicitly mention bleach in their warranties, most state that damage caused by improper cleaning methods or maintenance is not covered. Bleach is a strong oxidizing agent that can react with the organic compounds in asphalt shingles, leading to premature aging, discoloration, and weakening of the shingles. This damage may not be immediately apparent, but over time, it can lead to more severe issues like cracking, curling, or breaking of the shingles.

To maintain your roof effectively and protect your warranty, it’s best to follow the manufacturer’s recommended maintenance and cleaning guidelines or hire a professional roof cleaning company that uses safe and effective methods.
