Truckee inventor founds Weather-Tech Fasteners

Truckee resident David Curtis, inventor, retired roofing contractor and founder of Weather-Tech Fasteners has developed and patented a new fastener line for metal roofing and steel buildings.

Curtis was tired of the old-style, self-sealing hex head screws coming loose every year or two, even though it meant repeat work. The fact that people spend a lot of money maintaining their roofing screws is costing homeowners and the industry a lot of money,” said Curtis. Curtis researched the flaws of the old hex screw for years and developed fasteners based on what he didn’t like about the hex heads.

The high profile of the hex head holds snow and ice on the roof, when it gets too heavy and slides it unscrews and breaks the old hex. Curtis’ screws are extremely low profile to let snow and ice off before it builds up to a damaging weight. The hex wobbles and falls over when you are installing it so it must be stabilized with one hand and drilled with the other causing finger burn, cuts and metal splinters. Curtis’ screw is easily installed with one hand. The hex head is tightened against the rubber seal. Curtis’ screws have sharpened locking teeth that make metal to metal contact with the panel “like a bolt against an engine block” to help it stay tight. Over tighten a hex screw and the rubber seal breaks, Curtis’ screws have a recess to trap and protect the seal. The center hole of the hex is notorious for leaking even when the screws look tight. Curtis’ designs eliminate the center hole leaking issue.
