Gulf Coast heat, humidity and storm season strip the oils out of asphalt shingles years before the roof actually fails — and in Florida, a roof's age alone can cost you your policy. JG Construction puts those oils back, in a single day, for a fraction of what a Northwest Florida replacement costs.
Performance figures reflect independent PRI Construction Materials Technologies laboratory testing of GreenSoy™ treated asphalt shingles. Results vary by roof condition, age and shingle type.
Why Gulf Coast roofs age early
An asphalt shingle is not a solid piece of material. It's a fiberglass mat saturated with asphalt oils, with ceramic granules pressed into the surface. Those oils are what make the shingle flexible, waterproof, and able to hold onto its granules. From the day it's installed, the roof starts losing them.
Northwest Florida takes them faster than almost anywhere. Heat, humidity and eighty inches of rain in a bad year. A Gulf Coast roof works harder in twelve years than a northern roof does in twenty-five. Every summer bakes a little more oil out of the asphalt. Every storm pulls a few more granules into the gutter. Algae settles into the surface and feeds on what's left. Neither one shows up until the roof stops looking like a roof — and by then the homeowner has usually already been quoted a replacement.
A roof is like skin. Dry it out and it cracks. Put the oil back and it flexes again.
Average highs run 76 to 81 degrees year-round, and the surface of a dark asphalt roof runs far hotter than the air above it. Heat is what drives the volatile oils out of asphalt, and here it works every month of the year — there is no off season.
Pensacola is one of the wettest cities in the continental United States. Recent years have run from 59 inches to over 88. Add storm season, and shingles that have lost their flexibility get tested harder than they were ever built for.
The black streaks on roofs all over this county are algae, not dirt, and they feed on the limestone filler in asphalt shingles. Gulf humidity keeps them alive year-round — and they take hold exactly where the granules have already thinned.
The third option
Most products sold for an aging roof sit on top of it. A coating is a film — it covers the shingle, adds weight, changes how it sheds water, and eventually it fails and peels. In a climate this hot and this humid, a film that traps moisture underneath it is the last thing your roof needs.
GreenSoy™ does the opposite. It's a bio-based, soy-derived oil that penetrates the asphalt matrix and replaces what a decade of Gulf Coast summers took out. The shingle regains flexibility from the inside. Granules re-adhere. The roof goes back to behaving like a roof — not like a roof wearing a raincoat.
It's sprayed on. It soaks in. There's nothing left sitting on the surface.
Soaks into the asphalt matrix and restores flexibility from within. No film, no added weight, nothing to trap Gulf humidity or peel off in three summers.
Granules are the shingle's armor against UV and against algae. Restoring oil helps the shingle grip them instead of shedding them into your gutters every storm.
A flexible shingle expands and contracts through a Florida summer without cracking. A brittle one splits, curls and lifts — and a lifted shingle is where the next storm starts.
USDA Certified Bio-Based. Nothing torn off, nothing hauled away. About 11 million tons of shingle waste hit US landfills every year — none of it from this.

Florida homeowners
Florida law protects a roof under 15 years old: an insurer can't refuse to write coverage on age alone until it crosses that line. After 15 years, that protection is gone. Carriers inspect. Citizens requires it. Some non-renew. Some surcharge. Some simply decline to write the policy at all — on a roof that isn't leaking and hasn't failed.
And asphalt shingles in Florida conditions are commonly put at 12 to 15 years of service life, against 20 to 25 in milder climates. Which means a great many Escambia and Santa Rosa County homeowners are arriving at that 15-year line with a roof that is chemically tired but structurally fine — and being quoted eleven to eighteen thousand dollars for a replacement because of it.
Rejuvenation restores the shingle. It does not change the date on the permit, and nobody can promise you what your carrier will do. What it does produce is documentation: dated before-and-after photography, a written condition report, treatment records, and a 6-year transferable warranty certificate. That's a professional maintenance record on a roof that would otherwise have nothing but its age attached to it.
The black streaks
Every homeowner in this county knows what those black streaks look like. Almost nobody knows what they are.
They're algae — a blue-green algae that thrives in Gulf humidity and feeds on the limestone filler inside asphalt shingles. It doesn't settle on a healthy roof by accident. It takes hold where the granules have thinned and the surface holds moisture, which is to say it grows exactly where the shingle has already started losing its oils. By the time you can see it from the driveway, the roof underneath has been going for a while.
Left alone it makes the problem worse. It holds moisture against the shingle, it keeps working on the filler, and it spreads down the slope with every rain.
So we take it off first. We won't apply the rejuvenation treatment over algae — you'd be paying to treat a roof that's still being fed on. Soft washing is prep, not an upsell, and when it's done on the same visit as the rejuvenation it's priced accordingly.
Every JG Construction treatment carries a 6-year transferable warranty on treatment performance, handed to you in writing the day the work is done.
Transferable matters more in Florida than almost anywhere. Roof condition and roof documentation are among the first things a buyer's inspector and their insurer look at down here. If you sell inside those six years, the warranty goes with the house — along with the photographs and the condition report.
Pick a time on Junior's calendar. Takes about a minute. No deposit, no obligation, no salesman sitting in your kitchen.
Junior inspects the roof himself — shingle condition, granule retention, flashing, age, penetrations, and how much algae the roof is carrying. He's looking for one thing: whether rejuvenation is actually the right call for your roof.
You get photos of your own roof and a plain-English report. If it qualifies, you get a fixed quote — including the soft wash if the roof needs it first. If it doesn't qualify, he tells you that and you owe nothing.
Algae comes off first if there is any. Then GreenSoy™ is sprayed across the full roof surface. Most Escambia County homes are done in a day. No tear-off, no dumpster, no crew in your house.
Before-and-after photos, written completion report, and your 6-year transferable warranty certificate — delivered before we leave.

Replacement figures reflect published 2026 Northwest Florida market ranges for asphalt shingle replacement across Escambia, Santa Rosa, Okaloosa and Walton counties, and will vary by roof size, pitch, complexity and material; coastal and beachfront properties typically run 10–25% higher. Rejuvenation pricing is quoted per roof after inspection. Rejuvenation is only appropriate for asphalt shingle roofs that qualify — a roof past the point of restoration needs replacing, and Junior will tell you so.
It's an oil replenishment treatment for asphalt shingles — not a replacement, not a coating, not a cleaning. A bio-based oil is sprayed onto the roof and penetrates the shingle, restoring the flexibility, granule adhesion and weather resistance that years of Gulf Coast heat and humidity have stripped out.
Junior comes out and looks at it — free, and with no obligation. He evaluates shingle condition, granule retention, age, flashing and overall structural soundness. Most asphalt roofs between 6 and 20 years old are candidates. If yours isn't, he'll tell you straight and you won't owe anything.
GreenSoy™ is a soy-derived, bio-based rejuvenation product, USDA Certified Bio-Based. Instead of sitting on top of the shingle like a coating, it penetrates the asphalt and replaces the oils that have been lost over the years.
Most homes in Escambia and Santa Rosa County are done in a single day. There's no tear-off, no heavy equipment and no dumpster. Most homeowners stay home while we work.
A 6-year transferable warranty on treatment performance, provided in writing the day the job is completed. If you sell the house within those six years, it transfers to the new owner.
Yes. Heat is not a limitation for the product — the practical limit is how hot it is to work on a roof safely, not how the treatment performs. Humidity isn't a factor either. The roof surface needs to be dry when we apply, so we work around rain rather than around the season. That's why booking a few days out beats trying to squeeze it in during a wet week.
We won't promise you that, because nobody honestly can. Rejuvenation does not reset your roof's age, doesn't guarantee a renewal and doesn't lower a premium. What it does give you is documentation — dated before-and-after photos, a written condition report and a warranty certificate — on a roof that otherwise has nothing attached to it but a date. Florida carriers can decline or non-renew on roof age alone once a roof passes 15 years, so talk to your carrier directly about what they want to see.
A full asphalt shingle replacement in Northwest Florida typically runs $8,000 to $20,000 or more, with a typical 2,000 square foot roof landing between $11,000 and $18,000 — and coastal properties running higher still. Rejuvenation is a fraction of that. Pricing depends on your roof, so the free inspection includes a fixed written quote with no obligation.
Yes, but not over them. Those streaks are algae, and they have to come off first — treating over them means paying to rejuvenate a roof that's still being fed on. Junior soft washes the roof and applies the treatment on the same visit where possible, and the wash is priced as prep rather than as a separate job. We don't pressure wash: high pressure strips off the granules the treatment is meant to protect.
Yes. GreenSoy™ is plant-derived and bio-based. We protect landscaping, driveways, gutters and downspouts before we spray, and we clean the site before we leave. Pets and family are fine to be home.
Yes. Junior is a native Spanish speaker and the whole job can be handled in Spanish from the first phone call to the written condition report.
