What is roof regeneration?
The Third Option Nobody Told You About
Most homeowners only hear two choices: patch it, or tear it off and replace it. Roof regeneration — also called roof rejuvenation or roof restoration — is the option in between, and it works with the roof you already have.
Asphalt shingles are made to flex. Over time, Hawaii's UV, heat, and salt air pull the natural oils out of them. The shingles dry out, stiffen, start curling and cracking, and shed the granules that shield them from the sun. That's not damage — that's aging, and aging can be treated.
Shingle Serum is a penetrating, non-film-forming treatment made from tall oil — a renewable byproduct of pine pulping, not a food crop. It doesn't sit on top of your roof like a coating. It is formulated to soak into the shingle, restore flexibility and help shingles hold onto their granules. Per the manufacturer, it's sprayed on white so our crew can verify even coverage, then dries clear as it penetrates. And it never goes on a dirty roof: every treatment starts with a professional roof wash that cleans off algae, moss, dirt and buildup and preps the shingles, so the serum can soak in the way it's meant to — wash and serum go hand in hand.
Soaks in. Not a coating. That's the whole idea.

5 Signs Your Roof Is Asking for Help
Walk outside and look up — then check your gutters. If you see these, your shingles are aging. Caught at this stage, they're exactly what regeneration is made for.
- 1Granule loss
Sand-like granules collecting in your gutters and at the bottom of your downspouts — that's your shingles' sun protection washing away.
- 2Curling edges
Shingle corners and edges lifting or curling as the material dries and shrinks.
- 3Cracking
Fine cracks across the shingle surface — dried-out asphalt can't flex with heat and wind anymore.
- 4Dry, faded appearance
The roof looks washed-out and thirsty compared to when it was installed. On the windward side, add dark algae streaks from all that rain.
- 5Reduced flexibility
Shingles that feel stiff and brittle instead of pliable — the surest sign the oils are gone.
How it works
Wash. Dry. Treat. Then We Come Back.
Every job starts with an honest inspection, because treatment only makes sense when the shingles are still a good candidate. If yours aren't, we'll tell you straight — and you pay nothing.
Professional Roof Wash
It starts with your free roof check — we confirm your shingles are in the treatment window — then a professional roof wash cleans off the algae, moss, dirt and buildup sitting on them. A clean roof is a prepped roof: the wash readies the shingles so the Shingle Serum can soak in properly. Wash and serum go hand in hand.
Inspect & Dry
With the roof clean, we inspect the whole roof up close and note which areas need more attention, then let the roof dry properly so the treatment can penetrate.
Treat — Same-Day Application
Shingle Serum is applied evenly across the qualifying roof. It goes on white so coverage is visible, then dries clear as it soaks in. No tear-off, no dumpster, no mess.
The One-Week Return Visit
One week after your treatment, we come back — free. Your choice: a free solar panel cleaning or a free gutter cleaning — much mahalos for trusting us with your roof. And we check how your roof took the tall oil. It's our quality check, built into every job.

Aging Is Treatable. Worn Out Is Not.
Regeneration works on shingles that are aging but still sound. Here's the honest line between the two — the same one we use at your free roof check.
A Good Candidate Treatable
- Aging or faded asphalt shingles
- Granules shedding, but still substantially present
- Edges starting to curl, fine cracking, dry and stiff feel
- Dark streaks and staining from windward rain and humidity
- Roof is still structurally sound — no leaks, no soft spots
Too Far Gone Needs a Roofer
- Exposed fiberglass or large areas of missing granules
- Missing, broken, or badly curled shingles
- Active leaks, damaged flashing, or soft spots in the deck
- Asphalt that has already degraded beyond recovery
If this is your roof, we'll say so to your face and point you to a qualified roofer. Selling you a treatment your roof can't use would be stealing, and we don't do that.
Why tall oil?
Why We Chose Tall Oil Over Soy, Corn & Nano
Four kinds of chemistry get sprayed on aging shingles: soy, corn, nano — and tall oil. We looked at all of them before choosing what we'd put on Oahu roofs, and it wasn't close. Here's the simple version of why.
From Pine — Not a Food Crop
Tall oil is a byproduct of Kraft pulping of pine — its name comes from the Swedish tallolja, "pine oil." It is not a vegetable oil, and it is not a food crop. The soy and corn products our competitors on Oahu spray start as food-crop oils. Ours starts as a tree.
It Penetrates — It Doesn't Coat
Shingle Serum is formulated to soak into the shingle itself — not sit on top of it as a surface coating. It's sprayed on white so our crew can verify even coverage, then dries clear as it penetrates — restoring flexibility and helping shingles hold onto their granules.
Proven in the Asphalt World
Tall oil genuinely works in asphalt. Tall-oil-based products are used as recycling agents blended into reclaimed pavement binder, because they soften aged binder and help it flow again. That's the same job an aging, dried-out shingle needs done — done by a chemistry from the asphalt world, not the kitchen.
Starts as a food-crop oil — soybean oil, from the same plant family your kitchen knows from cooking oil, salad dressing, and mayonnaise — chemically converted into a sprayable roof treatment. Food first, roof product second.
Same story, different crop: corn-based treatments start as food-crop oils and fermented corn sugars. However they're processed afterward, the starting point is a food crop.
Work the opposite way from a penetrating treatment: instead of soaking in, they sit on the surface of the shingle as a coating or barrier layer.
From pine — not a farm field, not a food crop — and formulated to penetrate into the shingle rather than coat it, with a working history in asphalt itself. For an asphalt shingle, tall oil is the better chemistry. Plain and simple.
Two of them start as food crops. One sits on the surface. Ours comes from pine — and soaks in.

Solar attic ventilation
Let the Sun Pull Attic Heat Out
A Hawaii attic traps serious heat. That heat pushes down into your living space, works your air conditioner harder, and bakes your roof deck and shingles from underneath — the side no treatment can reach.
As a Platinum Preferred Dealer for The Attic Depot, we also sell their solar attic fans. They're solar powered and whisper quiet, and installation is handled by a licensed contractor — plus a lifetime manufacturer warranty on the fan. Treatment on top, ventilation underneath — one plan for the whole roof.
Installed by a licensed contractor. The attic fan and its solar panel are installed by a licensed contractor — roof penetration, flashing, and panel mounting done properly, sealed right, and to code. No handyman shortcuts on your roof.
Licensed contractor installation — fan and solar panel installed by a licensed contractor
Runs when needed — smart thermostat switches on at 85°F, off at 70°F
Watches humidity too — sensor switches on at 75% RH, off at 60% — a real factor in Hawaii homes
No wiring — the 30W solar panel powers it; nothing ties into your home's electrical
Built for weather — galvanized steel, corrosion-resistant powder-coated finish, protective animal screen, hail and wind resistant
Every solar attic fan — including its solar panel — is installed by a licensed contractor. Ask about adding a fan at your free roof check: 808-427-0123.
The complete attic system
Two More Ways We Cool the Attic
As The Attic Depot's Platinum Preferred Dealer in Hawaii, we sell their full attic line — the same dealer agreement behind our solar attic fans also covers Radiant X radiant barrier and the DraftMaster stairway insulator. Ventilation moves hot air out; these two slow it down and seal it off.
Radiant X radiant barrier
Reflect Heat at the Roof Deck
Radiant heat is one of the largest contributors to attic heat buildup — the sun heats your roof, and that energy radiates straight into the attic. Radiant X is a spray-on radiant barrier coating applied directly to the underside of the roof decking, reflecting up to 81% of radiant heat before it ever enters the attic space.
Traditional insulation slows heat after it enters the attic. Radiant X addresses it at the source — and it's not a replacement for insulation, it works alongside it: barrier at the deck, insulation at the floor, fan moving air out. That's a complete system.
Cooler attic — less radiant heat gain where it starts
Less HVAC strain — ductwork and living space sit under a cooler attic
Professional application — sprayed with an airless sprayer by our trained crew; slight odor dissipates in about an hour
Lifetime manufacturer warranty — per The Attic Depot
DraftMaster stairway insulator
Seal the Hole in Your Attic Floor
Most attics are insulated across the floor — except the stair opening, which is often left as a bare, uninsulated gap between your cool living space and a hot attic. The DraftMaster is an insulated cover that seals that opening shut.
It's built from double-bubble radiant foil that reflects up to 96% of radiant heat, and when installed properly it's R-15.2 rated — it creates a sealed dead-air space over the opening. A heavy-duty zipper system opens it completely in seconds, so the attic stays easy to reach.
Blocks drafts — seals the air leakage at the attic access point
Keeps attic dust out — a barrier against dust, insulation fibers, and insects entering living spaces
Fits your opening — 16 sizes for pull-down stairs, hatchways and scuttle holes, and walk-through attic doors
Installs in minutes — no major modifications; works with your existing insulation
10-year manufacturer warranty — per The Attic Depot

The Real Truth About Roof Rejuvenation
Aloha Roof Regeneration is NOT a roof repair company — and there is no spray that can fix a roof.
Our Shingle Serum treatment is regeneration: a penetrating tall-oil treatment formulated to restore flexibility to aging shingles and reduce granule loss. It does not fix leaks, replace missing or broken shingles, repair flashing, or correct structural damage. If your roof has damage like that, it needs a qualified roofer first — and we will tell you that honestly at your free roof check rather than sell you a treatment your roof can't use.
And one more piece of the truth: ARMA — the shingle manufacturers' association — is in the business of selling asphalt shingles. They're not in the business of extending the life of the one you already own. We are. Their position against treatments like ours isn't based on any study they've done — it's based on what they sell: a brand-new roof, the most expensive answer a homeowner can get, and the only one they offer. If your roof qualifies, regeneration is the smarter spend — and if it's too far gone, we'll tell you that too, straight. We're not selling you — we're telling you the TRUTH, and then the choice is yours.
We put this on our website, our quotes, and our invoices, in plain words — not fine print — because the fastest way to lose a homeowner's trust is to sell them something their roof doesn't need.
Common questions
What Homeowners Ask Us
Straight answers before you ever pick up the phone. If your question isn't here, call or text and we'll answer it directly.
What is roof regeneration?
Roof regeneration is a treatment for aging asphalt shingle roofs. As shingles age in Hawaii's sun and salt air, they lose the natural oils that keep them flexible, so they dry out, crack, curl, and shed granules. Our Shingle Serum treatment is a penetrating tall-oil formulated to soak into the shingles, restore flexibility and reduce granule loss — it works with the shingles you already have instead of covering them with a coating. Roof regeneration, roof rejuvenation, and roof restoration all describe this same treatment.
Is my roof a good candidate for roof rejuvenation?
Good candidates are asphalt shingle roofs that are aging — granule loss, curling edges, cracking, a dry or faded appearance, or reduced flexibility — but are still structurally sound. Roofs with exposed fiberglass, badly curled or missing shingles, or asphalt that has degraded beyond recovery are past the treatment window. A free roof check settles it: we inspect your shingles and give you an honest answer either way. The scorecard above gives you a head start.
How is Shingle Serum different from a roof coating?
Shingle Serum soaks in — it is not a coating. The manufacturer describes it as a non-film-forming, penetrating treatment made from tall oil, a renewable byproduct of pine pulping (not a food crop). Instead of sitting on top of the shingle as a topical layer, it is formulated to penetrate into the shingle itself. That distinction matters: a non-permeable surface film can trap moisture against the shingle, while a penetrating treatment works from inside the shingle itself — which is why we apply Shingle Serum instead of a surface film.
Will roof rejuvenation affect my shingle manufacturer's warranty?
Here's the truth about that question. ARMA — the shingle manufacturers' association — is in the business of selling asphalt shingles. They're not in the business of extending the life of the one you already own. We are. Shingle Serum stands on its own: it's backed by a 7-year manufacturer warranty from The Attic Depot. And at your free roof check, we'll give you a straight read on your roof and answer the warranty question for your specific shingles before you decide anything.
Is there proof rejuvenation adds years to a roof?
Yes — here's what stands behind it. Tall oil is proven chemistry in the asphalt world: tall-oil-based agents are used to soften aged asphalt binder and help it flow again in reclaimed pavement — the same kind of restoration an aging, dried-out shingle needs. Shingle Serum is formulated to penetrate the shingle, restore flexibility and reduce granule loss. The treatment is backed by a 7-year manufacturer warranty. If your roof qualifies, regeneration is the smarter spend — and if it's too far gone, we'll tell you that too.
Does roof regeneration fix leaks?
No — and no spray can fix a roof. Aloha Roof Regeneration is not a roof repair company. Our treatment does not fix leaks, replace missing or broken shingles, repair flashing, or correct structural damage. Leaks and damage must be repaired by a qualified roofer first; after that, regeneration can help the repaired roof's shingles stay flexible. We'll tell you honestly at your free roof check.
What happens during the treatment process?
It starts with a free roof check to confirm your roof is in the treatment window. Then comes the professional roof wash. With the roof clean, we inspect the whole roof up close and note which areas need more attention, let it dry properly, and apply Shingle Serum, which goes on white so we can verify even coverage and dries clear as it penetrates. One week later we return, free of charge — your choice of a free solar panel cleaning or a free gutter cleaning — and check how your roof took the tall oil.
What does roof rejuvenation cost?
Every roof is different, so we don't publish one-size prices. Your roof check is free, and after we inspect your roof we give you a fair, transparent quote for your roof — no pressure and no haggling. Call 808-427-0123 to book.
Do solar attic fans really help in Hawaii?
Attic heat builds fast under a Hawaii roof and bakes shingles from underneath while pushing heat into the living space. Our solar attic fan uses a 30W solar panel to power a 24V brushless motor moving up to 1,550 cubic feet of air per minute — no household wiring needed. A smart thermostat switches it on at 85°F and off at 70°F, and a humidity sensor switches it on at 75 percent relative humidity and off at 60 percent. The fan carries a lifetime manufacturer warranty.
Who installs the solar attic fan and its solar panel?
The attic fan and its solar panel are installed by a licensed contractor. That means the roof penetration, flashing, and panel mounting are done by a licensed contractor — properly sealed and installed to code — not a handyman add-on.
