Has Flat Shingles Losing Granules
Granules collect in the gutters, yet the tabs still lie flat and stay fastened.

As a Papillion shingle roof coating contractor, we coat asphalt shingle roofs on commercial buildings once the shingles are firm, flat, and repaired.
Papillion shingle roof coating fits shingles that still do their job. These cards show the line between coating and reshingling.
Granules collect in the gutters, yet the tabs still lie flat and stay fastened.
Wind took a handful of shingles, and the rest of the roof is intact.
Algae and sun have aged the surface while the shingles stay firm.
Tabs cup upward, rows slip, or the deck gives underfoot.
Shingle coating answers a narrow set of problems. These are the ones we see on commercial buildings in town.
Sun and age loosen the mineral surface on the shingles.
After a gentle wash, a coating made for asphalt shingles is applied in measured coats over the worn surface.
Step flashing and counterflashing have pulled loose or cracked at the wall line.
Flashing is resealed or replaced before coating, then the coating carries over the repaired joint.
Older sealant strips let go and gusts lifted the tabs.
Missing and broken shingles are replaced to match, then sealed down before any coating goes on.
Valley metal and vent boots wear out sooner than the shingles around them.
We replace worn boots, seal the valleys with fabric and base coat, and coat across them.
Shingle coating jobs vary mostly in prep and coverage. This spec sheet lists the options we pick from.
| Option | Best On | Prep It Needs | Recoat Later With |
|---|---|---|---|
| Full shingle coating | Flat, firm shingles losing granules | Wash, shingle repairs | Same shingle coating |
| Coating after tab repairs | Roofs with a few missing tabs | Replace and seal tabs | Same shingle coating |
| Valley and flashing detail | Roofs leaking at joints | Fabric and base coat | Same shingle coating |
| Slope-only coating | Sun-facing slopes wearing faster | Wash, repairs on that slope | Same shingle coating |
| Reshingle | Curling, sliding, or soft decks | Tear-off and new shingles | Not a coating job |
A shingle coating adds a weather layer over shingles that still hold. Here is what changes on the roof.
Tell us the building type and roof size. We check whether the shingles are firm enough to coat or need replacing.
Shingle coating depends on the inspection gate. If the shingles pass, these steps follow in order.
We lift tabs to check the seal, look for curling and soft deck, and check flashing at walls, vents, and valleys. Roofs that fail this check get a reshingle quote.
Missing and broken shingles are replaced, lifted tabs are sealed down, and worn vent boots and valley metal are swapped out.
A low-pressure wash removes dirt, moss, and loose granules without stripping the shingles, then the roof dries fully before coating.
Flashing at walls and penetrations is resealed, and valleys get fabric and base coat so the joints carry an extra layer.
A coating made for asphalt shingles goes on in measured coats, and we check coverage slope by slope before calling the roof done.
Many shingled buildings sit next to steel or flat roofs. These systems cover the other sections.

Steel warehouse sections behind a shingled office get a metal roof coating system matched to their screws and laps.

Pitched metal outbuildings on the same lot can take acrylic during the same warm-weather window as the shingle job.

Uninsulated metal shops on church or office grounds can take foam for insulation, separate from the shingled roof.

It falls inside the coating planning range of about $2.50 to $4.00 per square foot, with replacement at about $5 to $8. Shingle condition drives where a job lands. Tab replacement, flashing work, cleaning, and safety setup on steep pitches all add time.
Yes, when the shingles are dry, firmly fastened, and clean. We wash the roof, replace missing or broken shingles, and reseal flashing first, then apply a coating made for asphalt. Curled or water-damaged shingles are poor candidates, since coating will not reattach them.
The city’s Building and Fire Safety Department decides that. Papillion has adopted the 2018 International Building Code and International Existing Building Code, and its permit forms cover re-roof work. We confirm with the department before the job starts.
Coat when the shingles lie flat and hold most of their granules. Reshingle when they curl, crack, slide, or sit on soft decking. A coating adds a weather layer over aging but intact shingles. We check offices, churches, and storefronts tab by tab before recommending either one.
It depends on the shingles underneath, the coating thickness, and sun exposure. A coating will not outlast shingles that keep breaking down below it. Sunny slopes wear faster than shaded ones, and hail can cut the film. Yearly inspections and touch-up coats keep the shingles covered.
