Roof Rejuvenation in Hershey, PA

If you own an asphalt shingle roof in Hershey or the surrounding Derry Township developments 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 80-85% less than a full replacement. We start with a free inspection and tell you whether treatment is the right call.

What do roofs look like in Hershey?

Hershey is a planned "company town" at heart. Laid out around the chocolate factory in the early 1900s, with the recognizable streets near Chocolate Avenue and Cocoa Avenue and the landmarks that draw visitors to Hersheypark year after year. That planned origin means much of the housing came in coherent waves: sturdy early-1900s homes near the town center, a big band of mid-century ranches and split-levels, and generous newer subdivisions spreading across Derry Township toward Hummelstown and Palmyra. That mid-century-to-newer stock is right in the roof-rejuvenation sweet spot, with wide, simple roof planes that treat beautifully.

Why do Hershey roofs age the way they do?

Sitting in the Susquehanna's broader river valley, Hershey gets hot, humid summers and cold winters. Strong afternoon sun on exposed south- and west-facing slopes bakes the protective oils out of asphalt shingles, while valley humidity keeps roofs damp longer after storms and encourages algae streaking on shaded slopes. Once the oils are gone, the shingle stiffens and granules wash into the gutters. Then Dauphin County's freeze-thaw winters cycle above and below freezing, working at any brittleness that's setting in. Rejuvenation is designed to put those oils back before the shingle turns brittle, which is exactly why so many of Hershey's mid-life suburban roofs are ideal candidates right now.

Wondering whether your roof qualifies? The short version: asphalt shingles roughly 6–20 years old that are dry or fading but still sound, with no active leaks. See the full qualification checklist.

The mid-century and newer developments across Derry Township tend to hit that sweet spot particularly well right now. Our treatment is corn-based and 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 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 reduced granule loss by approximately 53% on 15-year-old shingles after treatment. That's lab testing, not a sales claim. And it matches what we see on tired suburban roofs that are simply thirsty rather than failed. Rejuvenation costs a small fraction of a full replacement.
