In general, Exposed Fastener roofing has shown itself to be a risk for leaks. When the screw becomes loose or backs out of the roof altogether, you now have an opening on your metal roof which can cause a leak. Once this happens, screws can loosen and back out of the wood deck. Over time, this thermal movement of the metal panels puts repetitive pressure on the thousands of screws in your roof causing the screw holes to enlarge. How does a screw “back out?” When your metal roof is exposed to extreme temperatures and weather, the metal will expand and contract. However, this traditional method of roofing attachment has proven to be problematic because the exposed screws used during installation tend to be over tightened, rust, or back out over time.
