How long do EPDM washers last on a roof?
Quality UV-stabilized EPDM washers typically last 15-20 years. In extremely hot climates (surface temperatures above 80°C), lifespan may reduce to 10-15 years. Always choose screws with UV-stabilized washers for roof applications.
Can I reuse roofing screws after removal?
No. The EPDM washer takes a compression set after installation and will not reseal properly if removed and reinstalled. Always use new screws for any re-roofing or repair work.
