Cofair Products makes self adhesive waterproofing membranes and flashing tapes from Morton Grove, Illinois, and has been at it for more than 25 years. RV owners meet the company through the Quick Roof family: Quick Roof, Quick Roof Extreme, Quick Roof Ultra Bond, plus Clear Patch and the emergency rubber roof patch kit that ships with alcohol wipes and a scrub pad. Its Steel Loc adhesive blends synthetic copolymers with butyl rubber, installs without primer at temperatures down to 20 F, keeps holding from minus 70 F to 200 F, and carries a guarantee against cracking, hardening and shrinking.
The rest of the range is construction work: window and door flashing, gutter and driveway repair, deck and skylight sealing, with published technical data sheets for each product. Sales go through dealers, hardware chains and big box retailers rather than direct, so prices for the same roll swing widely between sellers. Naming is the other snag, since Extreme, Ultra Bond and the plain white EPDM roll look alike on a shelf but differ in facing and adhesive. Aluminum faced versions are stiff to work into curves.
