NMDL Roofing | Roofing Services in Rockland, MA 02370

In our area, skylight leaks are often caused by failed flashing—the metal strips that seal the joint between the skylight and the roof. Harsh winter ice dams and general weathering can crack or loosen this critical seal. Our repair process involves a careful inspection to locate the breach, removal of the surrounding shingles, and replacement of the flashing with new, corrosion-resistant materials. We then re-integrate it seamlessly with your existing roof system to prevent future water intrusion.

Moss thrives in the shaded, damp conditions common in many Rockland neighborhoods. After a professional soft-wash removal, we recommend installing zinc or copper strips along the ridge of your roof. When it rains, tiny particles of these metals wash down the roof, creating an environment that inhibits moss and algae growth for years. We also advise trimming back overhanging tree branches to increase sunlight and airflow, which are natural deterrents to moss.

This depends entirely on the extent of the damage and the overall condition of your roof. For isolated issues like a single leaking skylight or a small section of moss damage, a targeted repair is often the most cost-effective solution. However, if your roof is nearing the end of its lifespan (typically 20-25 years for asphalt shingles in our climate) or has widespread wear, a replacement may be a wiser long-term investment. We provide a transparent assessment and will only recommend a full replacement if it's truly necessary for the protection of your home.
