If you own an asphalt shingle roof in the Allentown–Bethlehem–Easton metro and it's roughly 6–20 years old, dry, and shedding granules, our corn-based rejuvenation can restore flexibility and add years of service life — for about 15–20% of what a full replacement costs. We start with a free inspection and tell you honestly whether treatment is the right call.

Why do Lehigh Valley roofs age the way they do?

The Lehigh Valley is one of Pennsylvania's fastest-growing metros, and the 2000s build boom across Allentown, Bethlehem, Easton, Lower Macungie, Upper Macungie, and Whitehall produced exactly the kind of asphalt roofs that qualify for rejuvenation now. The valley's summer heat and humidity bake oils out of shingle asphalt, while cold winters and freeze-thaw cycles work at any brittleness that follows. The result: many 12–16-year-old roofs look tired, shed granules into the gutters, and get quoted for replacement when they're actually still sound and simply thirsty. Rejuvenation replaces those oils before the shingle turns brittle.

The honest scope: rejuvenation restores aging-but-intact shingles. It does not fix leaks, flashing, or missing/cracked shingles, and it won't rescue a roof that's already failed. On some older homes, replacement is the smarter money — and we'll tell you when that's the case.

Is my roof a candidate?

Asphalt shingle roof, roughly 6–20 years old
Dry, faded, or shedding granules — but structurally sound
No active leaks; shingles present and not cracked

The developments across Lehigh and Northampton Counties are hitting that sweet spot right now, and plenty of re-shingled older homes qualify too. Our treatment is corn-based and about 95% USDA-certified bio-based; it penetrates the shingle rather than coating it, so it works across brands without changing how your roof looks. Each treatment adds 5 years of restored shingle flexibility, backed by our 5-year transferable warranty. With periodic re-treatment, many qualifying asphalt roofs gain 10–15 years of added service life.

Does the treatment actually work?

The evidence comes from independent ASTM lab testing performed by PRI Asphalt Technologies, which measured restored shingle flexibility and reduced granule loss by approximately 53% on 15-year-old shingles after treatment. That's lab testing, not a sales pitch — and it lines up with what we see on tired roofs that are simply thirsty rather than failed.

Commercial roofs, HOAs, and apartment portfolios

The Lehigh Valley's townhome communities, condo buildings, and apartment portfolios make it an important commercial market for us — serving those boards and property managers across the 100-mile ring is core to what we do. Boards get a free portfolio-level walk-through, a prioritized proposal, phased scheduling, and full insurance documentation — certificates of insurance, W-9, and any additional-insured endorsement required. See our Commercial & Multi-Family page for the full picture.
