Does roof rejuvenation actually work on Biddeford, ME roofs?

Why shingles fail here in the first place

An asphalt shingle stays watertight because the asphalt binder holding the mat together stays flexible. Sun and heat cycling drive the oils out of that binder over time, and a stiff shingle cracks when it's asked to expand and contract. Coastal exposure at the Pool and along Fortunes Rocks brings salt and wind; inland Biddeford sees heavy snow retention. Freeze/thaw stress on steep older roofs shows up first at valleys and flashing.

What the treatment does — and doesn't

• Does: soak into the shingle and restore flexibility to the asphalt
• Does: slow granule loss and reduce cracking on aging but sound shingles
• Doesn't: replace missing shingles or seal an active leak
• Doesn't: fix flashing, ventilation problems or a soft deck
• Doesn't: work on roofs that have already structurally failed

What we look at on Biddeford roofs

Every assessment is done on the roof, not from the driveway. In Biddeford we're paying particular attention to:

• Steep multi-family roofs with wear concentrated at valleys
• Salt and wind weathering on Pool-area properties
• Aging shingles on rental properties with deferred maintenance
• Granule loss visible along street-facing eaves

The honest version

Roughly speaking, a good share of the aging roofs we look at qualify and a meaningful share do not. We would rather tell you no and refer you to a roofer we trust than take money for a treatment that won't help. That's the whole business model.
