Curling Tab Edges
- You See
- Tabs lifting at the corners across a slope.
- What It Means
- Curled tabs crack under coating and let wind in. Widespread curling points to reshingling.

As a Hazleton shingle roof coating contractor, we coat commercial asphalt shingle sections, such as mansards and steep faces, once both makers approve the pairing.
Hazleton shingle roof coating has a narrow fit. Most of the decision comes down to the shingles themselves.
| Roof Detail | Good Fit | Repair Or Reshingle |
|---|---|---|
| Tabs | Flat and sealed down | Curled, lifted, or missing |
| Granules | Most still in place | Bare mat showing |
| Flashing | Tight at walls and curbs | Rusted or pulled loose |
| Approvals | Shingle and coating makers agree | Either maker says no |
| Deck | Firm underfoot | Soft or sagging |
Coating covers shingles; it does not fix them. These conditions decide whether coating makes sense.
Shingle work runs from a coating to a full reshingle. These are the four outcomes we see most.
Sound shingles with maker approval get cleaned and coated with the specified product. Faces are cleaned and dried a day ahead so the coating bonds.
A few damaged shingles and flashings are replaced, then the face is coated. Replacement shingles are matched as closely as the maker allows.
Widespread curling or granule loss points to new shingles rather than a coating. A photo report shows why coating was ruled out for those faces.
The flat roof inside a mansard can be coated with its own system at the same time. Doing both at once saves a second setup of lifts and staging.
On the right shingle roof, a coating buys time. Here is what it does.

A coating protects the remaining granules and mat from sun and rain. That protection matters most on south and west faces that get full afternoon sun.
Faded, streaked shingle faces on offices and storefronts get an even color. A single color across all faces gives the building an even look from the street.
Flashing repaired during prep stops the most common mansard leaks. Walls, windows, and roof edges around a mansard are where leaks start most.
Healthy shingles with years left can stay in place longer under a compatible coating. That extra time lets you plan a reshingle when the budget is ready.
We check first whether coating fits. Start with a planning range for your building.
Shingle coating starts with paperwork as much as with the roof, because the makers decide what is allowed.
We check tabs, granules, nails, flashing, and the deck, and photograph each face of the mansard or slope. Each face gets a short note in the photo report.
The shingle maker's guidance and the coating maker's requirements for that shingle are checked before quoting. Approvals are kept on file with the job records.
Damaged shingles are replaced and step flashing, counterflashing, and edge metal are refastened and sealed. Nails that have backed out are reset or replaced.
The faces are gently cleaned, dried, and coated with the approved product at the specified rate. Coverage is checked on every face before the crew moves on.
Walkways and doors below the work are covered, and work near entrances is timed around the building's hours. Staging stays clear of signs and windows.
The flat or metal roof next to the shingles may need one of these.

Only where both makers support the combination and the shingles are in good shape. We check adhesion requirements, tab condition, and drainage first. Curling, loose tabs, or broad wear point toward repair or reshingling rather than coating. A short photo report of each face shows you what we saw before any decision is made.
Coating plans out at about $2.50 to $4.00 per square foot of roof, and replacement at about $5 to $8. Size, access, coating type, thickness, coats, and flashing or penetration work set where a shingle job lands. Mansards with many windows or wall joints take more flashing work, which moves the price up.
Very little. A price means nothing until we know the shingles can take a coating and the makers allow it. Compatibility and condition come first, then the price comparison makes sense. Once compatibility is confirmed, prices from different contractors become easy to compare.
It lasts as long as the shingles under it hold together. Exposure, adhesion, and the condition of the mat matter more than the coating's own rating. Brittle tabs, granule loss, and failing flashing shorten it. Steep faces that get full afternoon sun wear faster than shaded ones.
Offices, clinics, and retail buildings with mansards or steep faces are the usual fit, when the shingles are in good shape and the owner wants a few more years before reshingling. It rarely fits a roof already curling or leaking at many points.
We tell you plainly when a reshingle is the better use of the money.
