Peak Rejuvenation — GreenSoy roof rejuvenation in Wilmington, Delaware

A Wilmington Family Business, Not a Storm-Chasing Crew.

Peak Rejuvenation is owned and run by Brennan Del Genio. One service, done properly, for the community we live in.

Meet Brennan Del Genio

Brennan Del Genio founded Peak Rejuvenation with one goal: give Delaware homeowners a straight answer about their roof. After seeing neighbors pushed into full replacements they didn't need, he built a business around a single service — GreenSoy™ oil replenishment for asphalt shingles — and learned it inside out.

Wilmington homeowners are used to contractors who show up after a big storm and are gone by the next county. We're not that. We live here, our kids go to school here, and the roofs we treat are on streets we drive every week.

That's also why we'll tell you when a roof doesn't qualify. A treatment that won't work isn't a sale — it's a complaint waiting to happen.

The Science

Why Putting the Oils Back Actually Works

An asphalt shingle is a fiberglass mat saturated with petroleum-based oils and surfaced with mineral granules. The oils are the working part: they keep the asphalt flexible, hold the granules in the mat, and keep water out.

Delaware weather doesn't let up. Long humid summers bake the oils out of asphalt shingles, and then a winter of freeze-thaw cycles and coastal storms works the brittle mat apart until shingles curl at the edges and start shedding granules.

GreenSoy™ is a soy-derived, USDA certified bio-based oil with a molecular structure close enough to the original asphalt oils to be reabsorbed by the mat. Spray-applied, it penetrates rather than coats — no added weight, no trapped moisture, no film on top of the shingle.

Independent laboratory work by PRI Construction Materials Technologies has measured the results: roughly 80% improvement in shingle flexibility and zero granule loss in hail impact testing on treated shingles. That flexibility is exactly what matters in the Mid-Atlantic — every storm season puts your shingles through impact they were never designed to take twice.

UV Depletion

Sun drives volatile oils out of the asphalt mat year after year, faster here than nearly anywhere.

Molecular Match

Soy-derived esters are absorbed into the mat rather than sitting on the surface as a film.

Honest Eligibility

Structure and granule coverage decide the answer, not a quota. Some roofs are past saving.
