Your roof may have 15+ years left. Before you replace it, let us take a look.
Rowan Thomas Roof Restoration brings tired asphalt shingles back to life across Pembroke, Marshfield, Plymouth, and the South Shore — for a fraction of the cost of a full replacement.
Performance figures based on independent PRI laboratory testing. Results vary with shingle condition.
"Thomas was upfront about everything. Showed me the granule loss, explained the process, and the roof looks brand new. Saved us thousands."
"Professional from start to finish. Took photos before and after, sent the warranty in writing, and our shingles went from brittle to flexible again."
"We were quoted $14,000 for a replacement. Rowan Thomas rejuvenated it for a fraction of that. Two years later, still no leaks, no curling."
Your roof isn't failing. It's drying out.
Asphalt shingles are held together by oils that keep them flexible and waterproof. Over time those oils oxidize and evaporate — the shingle dries out, gets brittle, curls, and sheds the granules that protect it. Most roofs are replaced for dehydration, not actual failure.
"A roof is like skin — when it dries out, it cracks. When you restore the oils, it heals."
Coastal Salt Air
Salt accelerates oxidation and strips oils out of shingles faster than inland climates.
Freeze-Thaw Cycling
New England winters crack and curl shingles that have already lost their flexibility.
UV + Humid Summers
Sun and humidity pull oils out and bake the surface — aging roofs from the inside out.
GreenSoy™ Rejuvenation — not a coating. A restoration.
GreenSoy™ is a bio-based, soy-derived oil that penetrates into the shingle and replenishes the oils it has lost — restoring flexibility from within. It does not sit on top like a paint or a coating.

Backed by a 6-Year Transferable Warranty
Every treatment includes a written warranty on performance, provided at completion. Because it's transferable, if you sell the home the coverage passes to the new owner — adding documented value to the property.
Documented Roof Maintenance, On Record
A documented rejuvenation and inspection gives Massachusetts homeowners a written maintenance record for their roof. Many keep it on file with their insurer alongside other home maintenance documentation.
Coverage and requirements vary — always confirm with your own insurance provider.
