A flyer on the door says a spray treatment can buy your roof more time. The quote on the counter says tear it off. You want to know who’s right.
Here’s our answer, and we sell the treatment. Rejuvenation is meant to help asphalt shingles that are drying out but still sound. It does nothing for a roof that’s worn out. And plenty of roofs aren’t candidates at all, which is why the evaluation comes before any recommendation.
How we decide, and why the paperwork comes first
We decide in a set order, and the shingles themselves come last.
- Your shingle maker’s guidance. The company that made your shingles puts out its own guidance for them, and makers don’t all say the same thing about treatments added after a roof is on. If yours rules it out, we stop there.
- Your HOA rules, if you have one. Covenants can cover what goes on a roof. If yours rule a treatment out, we stop there too.
- The roof itself. Only then do the shingles, the granules and the deck come into it. That checklist is further down this page.
Why that order? A roof can look like a great candidate from the ladder and still be the wrong one to treat. If the maker or the HOA says no, how good the shingles look doesn’t change our answer. You should hear that before you spend anything, not after.
Why we offer it at all
We offer rejuvenation because some roofs are good candidates, and their owners want a real option before replacement. That’s the reason we opened.
But a treatment is never the default. The checks above come first, every time.
We’re a NexaNano Certified Dealer and Applicator, trained on NexaNano’s roof rejuvenation and protection products. That training doesn’t change the rule. We’d rather tell you no than treat the wrong roof.
What it’s designed to do
Shingles dry out as heat drives off what InterNACHI calls volatiles, the parts of the asphalt that keep a shingle flexible (InterNACHI). We walk through that process in why asphalt shingles dry out.
Rejuvenation is a treatment for aging asphalt shingles. Its job is to help restore flexibility and address some effects of aging. NexaNano, who makes the products we use, describes them as SiO2 (silicon dioxide) treatments “designed to penetrate porous surfaces while forming a breathable protective barrier.” It says the technology is meant to “integrate with the surface itself while still allowing trapped moisture vapor to escape” (NexaNano). Whether a treatment lets moisture out is a fair question to ask about any product on a roof.
Built for weather like ours
NexaNano also says its coatings are designed for conditions like “High UV exposure,” “Humid climates” and “Freeze/thaw conditions.” Evansville has all three. It averages 41 days a year at 90°F or hotter, and about 75 days that dip below freezing overnight and climb back above it, by our math on NOAA’s 1991-2020 normals.
What it can’t do
- It won’t stop a leak.
- It won’t replace missing shingles or loose flashing.
- It won’t firm up soft or rotted decking.
- It won’t bring back granules that already washed into the gutters.
- It won’t flatten shingles curling across whole slopes.
- It won’t keep algae from coming back. Cleaning is a separate step.
We also won’t put a number of years on it. Roofs here age at different rates, depending on shade, slope and how worn they were to start. Any figure we gave you for your roof would be a guess, and you deserve better than a guess.
Which roofs are candidates
Plenty of roofs aren’t. A good candidate tends to look like this:
- Asphalt shingles, still lying flat and sealed.
- No leaks and no ceiling stains.
- Granules still covering the mat, even if they’ve thinned.
- A firm deck.
- A shingle maker and HOA, if you have one, whose rules don’t rule it out.
Miss any of these and it isn’t a rejuvenation job. Some of those roofs need a roofer. Some only need cleaning. Some in fair shape are better suited to roof protection, a different treatment for a different roof.
Why the evaluation comes first
You can’t judge this from the driveway, and neither can we. At the free exterior evaluation, we inspect the roof slope by slope, take photos, and check the shingle maker’s guidance and any HOA rules. Then you get a straight answer: rejuvenate it, protect it, clean it, call a roofer, or leave it alone for now.
If your roof turns out to be a candidate, our roof rejuvenation page explains the work itself. To book, call or text Terrance at (812) 664-6222.
Common questions
Do shingle makers allow roof rejuvenation?
It depends on the maker, and they don’t all say the same thing. That’s why we check your shingle maker’s guidance, and your HOA rules if you have one, before we recommend anything. If either one rules it out, our answer is no, however good the roof looks. If neither does, the evaluation decides whether your roof is a candidate at all.
How long does roof rejuvenation last?
We don’t give a number of years, for any treatment. How a treated roof holds up depends on how worn it was, how much sun and shade it gets and the weather it sees. A number we gave you for your roof would be a guess. We’ll tell you what we actually see at the evaluation instead.
Does my HOA have to sign off on a roof treatment?
That depends on your HOA’s rules, which is why we read them before we recommend a treatment. If you’re in an HOA, have your covenants or architectural rules handy for the visit and we’ll go through the roof section with you. If the rules need a board sign-off, you’ll know before any work is scheduled.
