If you own an asphalt shingle roof in Reading or the surrounding Berks County suburbs 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.

What do roofs look like in Reading?

Reading is one of Pennsylvania's great brick cities, and its housing stock shows it. Climb Mount Penn toward the Pagoda and look back over the grid: block after block of tightly packed two- and three-story brick rowhomes, many dating to the industrial boom of the late 1800s and early 1900s. Those steep, narrow roofs have almost all been re-shingled at least once, so the asphalt you see today is typically mid-life rather than original. Push out toward Wyomissing, West Reading near the GoggleWorks, and the newer developments in Exeter and Spring Township, and the picture changes — you get the wider, simpler roof planes of mid-century ranches, Cape Cods, and post-2000 subdivisions that are ideal candidates for treatment.

Why do Reading roofs age the way they do?

The biggest culprit here is sun combined with the Schuylkill Valley's summer humidity. South- and west-facing slopes on the rowhome blocks catch heavy afternoon UV with little tree cover, and that's exactly what bakes the protective oils out of asphalt shingles. Once those oils are gone, the shingle stiffens and the granules let go — you start finding dark grit in the downspouts. Add Berks County's freeze-thaw winters, where daytime thaws and overnight refreezes work at brittle shingles week after week, and a mid-life roof can look a decade older than it really is. Rejuvenation is designed to put those oils back 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 of the oldest city roofs, replacement is the smarter money — and we'll tell you when that's the case.

Is my Reading 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 suburban developments around Wyomissing and Exeter tend to hit that sweet spot right now, but plenty of re-shingled city 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 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 Construction Materials Technologies, which measured roughly 46% less granule loss on 17-year-old shingles after treatment. That's lab testing, not a marketing claim — and it lines up with what we see on tired Berks County roofs that are simply thirsty rather than failed. A full replacement in this area typically runs $8,000–$16,000; rejuvenation is a fraction of that.
