Architectural shingles are a popular roofing choice due to their durability and aesthetic appeal, often resembling wood shake shingles with a multi-dimensional look. However, one common issue that can occur over time is fastener back-out, where the nails or staples securing the shingles gradually work themselves loose from the roof deck. This can happen because of several reasons including wind uplift, wood movement from changes in temperature or moisture, improper nail placement, or using the wrong type or length of fasteners during installation. When fasteners back out, shingles become less secure, increasing the risk of damage or loss during storms and potentially voiding manufacturer warranties. Homeowners can do a simple visual check on the roof or from a ladder, looking for nails that appear to be sticking up or shingles that seem loose or flapping in the wind. You should ensure any DIY checks are safe, avoiding walking on the roof unnecessarily, and only inspecting areas you can reach comfortably without risking injury.
If you notice fastener back-out or suspect it, it’s a good idea to call in a professional roofer to assess and repair the problem properly. The roofer will check for improper fastening techniques, damaged or rotted roof decking, and potential issues with attic ventilation that might contribute to wood movement. During your consultation, ask explicitly whether they will refasten the shingles with the correct nails and placement according to the shingle manufacturer’s guidelines, and if they can provide a warranty on their work that won’t interfere with your existing shingle warranty. Additionally, inquire about the type and length of fasteners used, making sure they meet or exceed roofing standards for your particular shingle product and local building codes. Taking these steps helps maintain your roof’s integrity and ensures your shingles continue to protect your home effectively.
