Synthetic shake roofing is a popular choice for its durability and appealing look, but sometimes homeowners notice fastener back-out, where nails or screws start to loosen and pop up. This issue typically happens because of natural roof movement due to temperature changes, improper fastening during installation, or the use of fasteners that aren’t compatible with the synthetic shake material. Over time, repeated expansion and contraction or wind forces can cause these fasteners to work loose, which could lead to shingles lifting or even leaking. To check for fastener back-out safely yourself, visually inspect your roof from the ground with binoculars or carefully climb a ladder to look for nails or screws that are not flush or appear raised. Be cautious on steep or slippery roofs, and avoid walking on synthetic shakes if you’re unsure, as damage can occur.
If you spot signs of fastener back-out, it’s wise to contact a professional roofer who understands synthetic roofing materials and proper fastening techniques. When choosing a contractor, ask if they use corrosion-resistant, manufacturer-approved fasteners and how they ensure fasteners won’t back out again, such as by using special-length nails or screws and correct spacing. Also, inquire about their experience with synthetic shakes specifically, since not all roofers are familiar with their unique requirements. It’s critical that any repairs respect your roof’s warranty, so ask if the fixes will void the manufacturer’s coverage. Timely attention can prevent bigger issues like water infiltration or shingle damage, saving you both money and stress.
