How did Master Roof handle the repair without replacing the entire roof?

Master Roof focused on a targeted repair around the skylight zone only, based on a thorough inspection and photo report. The process involved removing damaged shingles and water-affected sheathing, replacing weakened plywood for structural integrity, installing new high-performance GAF underlayment for waterproofing, adding matching new shingles, and securing fresh flashing around the perimeter to create a watertight seal—all while deferring other roof issues to minimize cost and disruption.

What were the key outcomes and benefits for the homeowner after the repair?

he repair successfully eliminated the leak, reinforced the skylight perimeter, and protected the home from future weather damage. Benefits included avoiding the expense and hassle of a complete roof replacement, preventing further interior water damage, and providing peace of mind through restored structural integrity and high-quality materials, all achieved in a focused, efficient manner.

Can this type of targeted skylight repair be applied to other homes with similar issues?

Yes, this approach is ideal for homes where leaks are isolated to the skylight area, as seen in this Franklin project. Master Roof's method—starting with a detailed inspection to identify underlying issues like sheathing damage—allows for customized, cost-effective repairs using premium materials like GAF underlayment, making it suitable for older roofs without necessitating a full overhaul.

Franklin MA Skylight Repair | Master Roof Leak Restoration

Skylight Rebuild in Franklin, MA

This home in Franklin, Massachusetts — built in the early 1960s — had begun experiencing persistent skylight leakage during rain and melting snow. The skylight itself was structurally sound, but the roof surrounding it was failing and no longer watertight. The homeowner requested a focused repair rather than a full roof replacement, prioritizing the most urgent concern: stopping the leak and preventing further interior damage.

Assessment & Findings

The original shingles surrounding the skylight showed signs of deterioration and improper sealing. Beneath the surface, the sheathing was beginning to darken and soften — classic evidence of moisture exposure. Once shingles were removed, the damage became much clearer (shown in the first set of images above): water infiltration had been occurring long enough to compromise both wood and older waterproofing materials.

Fortunately, the skylight unit itself was in good working condition. The failure was not the window — but the roof system around it.

Repair Strategy

Instead of a tear-off across the entire roof plane, Master Roof performed a targeted reconstruction. The damaged shingles and all surrounding layers were carefully removed, giving access to the water-affected sheathing. The weakened plywood was cut out and replaced to restore structural integrity.

With a clean base in place, the team installed new GAF underlayment — a high-performance waterproof membrane designed to resist wind-driven rain, ice-melt, and long-term moisture exposure. New shingles were then integrated to match the existing roofline, followed by fresh flashing and tie-ins around the perimeter of the skylight.

This precise method restored the watertight seal without requiring a full roofing system replacement.

Result

The transformation was immediately visible. Where soft decking and failed shingle seals once existed, a restored, reinforced, and fully waterproof perimeter now protects the home. The skylight no longer leaks, the new shingles blend cleanly into the roof plane, and the homeowner gained peace of mind for future weather seasons — without needing to replace the entire system at this time.
