Warnings & cautions

Roofing work means working at height — always use proper fall protection, secure footing, and follow local building codes. Sealants and adhesives can irritate skin and eyes, so wear gloves and eye protection and read the product label before use. When in doubt, have a licensed roofer handle the install.
