JSG Contracting and Remodeling | General Contractors & Roofing in Nashua, NH 03063

In our climate, shingle curling is often caused by moisture trapped in the attic from poor ventilation or from normal aging. As local roofers, we first inspect your attic ventilation. Fixing the root cause is key. We then assess the shingles; if damage is isolated, we can perform targeted repairs. For widespread curling, a full roof replacement with modern, impact-resistant shingles is the most reliable, long-term solution for Nashua homes.

Chimney leaks in our area are most commonly due to failed flashing—the metal seal between the chimney and roof. Over time, New Hampshire's freeze-thaw cycles can crack the sealant or loosen the flashing. Our process involves a detailed inspection to pinpoint the leak's source. We then repair or replace the flashing with high-grade, waterproof materials and proper sealing techniques, often without needing a full roof repair, saving you time and money.

Absolutely. During a kitchen or bath remodel, we proactively address water damage risks. This includes installing proper underlayment, using water-resistant materials like cement board behind tiles, ensuring correct plumbing fixture installation, and improving ventilation with quality exhaust fans. A remodel is the perfect opportunity to upgrade these critical systems, protecting your investment and preventing the mold and structural issues common in older Nashua homes.
