John Mcnamara Home Improvements | General Contractors & Roofing in Stoneham, MA 02180

In Stoneham, roof nail pops are often caused by the natural expansion and contraction of your roof decking and framing due to our seasonal temperature swings. Over time, this movement can push nails up, breaking the sealant and creating potential leak points. We fix this by carefully removing the popped nail, sealing the hole with roofing cement, and installing a new, slightly longer nail in a fresh location nearby, followed by a proper sealant application to ensure a watertight barrier.

Moss is more than just unsightly; it retains moisture against your roof shingles, accelerating granule loss and leading to premature rot and decay of the underlying wood. For Stoneham homeowners, this is a common issue due to our shaded, moist environments. Our safe removal process involves a gentle, low-pressure cleaning with a specialized biodegradable solution that kills the moss without damaging your shingles. We then can apply a zinc or copper-based treatment strip to help prevent future growth.

Absolutely. One of the key benefits of working with a full-service general contractor like us is our ability to manage the entire project. If a leak from a nail pop or moss-related damage has caused issues inside your Stoneham home—like stained ceilings or damaged drywall—we can coordinate and perform all necessary repairs. This includes the roofing fix, any interior demolition, remediation for moisture, and the final restoration work, providing you with a single, seamless solution and peace of mind.
