How do you screw a fiberglass ripple roof to a board and prevent leaki



I am putting a roof on an outdoor porch and wonder how you prevent rain-water from seeping through the hole. Do you use a rubber washer or is there a special screw, etc.?

    Go to where you bought the rippled roof and buy the gasket. You might have to buy several to run the length of the roof and they should have stainless steel screws there as well.

    i heard there's a brand called suntuf fasteners, they're widely threaded and have a special rubber washer attached. (* suntuf is also a brand used for their fiberglass roofing) however, they're pretty expensive. i've seen people use a generic brand/ buy separately, etc... however, all have also used a special adhesive caulk of some kind as well. Not quite up to verse on this subject, but hope this may help you get started.

    Do you have an honest to God hardware store near you? They'll fix you up with roofing screws ( sold by the pound). Make them your friends! Run into a problem like this in the future - & you can have your answer - & the solution in your hands. POOF!! signed - a profound hater of the home deputs in the world.....
