Granules In The Gutters
Gutters fill with dark grit after storms.
Likely Cause
The shingle surface is wearing and losing its protective granules.
What We Do
We check how much remains and whether an approved coating can protect what is left.

Is Lancaster Shingle Roof Coating Right for This Roof?
Lancaster shingle roof coating fits a narrow set of roofs. This table shows the line between coating and new shingles.
| What We Check | Coating Fits | Fix First | Replace Shingles |
|---|---|---|---|
| Shingle shape | Flat and flexible | A few lifted tabs to reseal | Curled, cupped, or brittle |
| Granules | Most still in place | Bare patches to spot-repair | Bare across large areas |
| Product approval | Coating approved for shingles | Approval to confirm in writing | No approved product exists |
| Flashing | Firm at walls and vents | Loose pieces to reset | Rusted or missing throughout |
| Attic and deck | Dry and ventilated | Small wet areas to fix | Soft or rotted decking |
Shingle Roof Coating Conditions on Lancaster Buildings
Commercial shingle roofs show these signs before an owner calls. Each one decides between coating and new shingles. Most begin in the gutters.
Lifted Tabs After Wind
A few shingles flap or stick up after a storm.
Likely Cause
The seal strips have let go on those tabs.
What We Do
Tabs are resealed or replaced before any coating is considered.
Stains Near A Wall
A ceiling stain sits under a roof-to-wall joint.
Likely Cause
Step or counter-flashing has loosened.
What We Do
Flashing is reset and sealed, since coating the field leaves that joint open.
Curling Across The Roof
Shingle edges cup or curl over large areas.
Likely Cause
Age and heat have dried the shingles out.
What We Do
We recommend new shingles, because a coating over curled shingles fails quickly.
Leaks Around Pipe Boots
Drips show under vent pipes after storms.
Likely Cause
Rubber boots around the pipes have cracked with age.
What We Do
Boots are replaced and sealed before the field of the roof is considered for coating.
Commercial Roof Coating Options for Lancaster
Shingle coating is one of four systems we work with in Lancaster. Here is where each one fits.
Approved Shingle Coating
Flat, flexible shingles with good granule cover can take a coating the maker approves for them.
Tab And Flashing Repair
Lifted tabs and loose flashing get fixed first, whether or not a coating follows.
Acrylic On Metal Sections
Metal porch roofs or canopies on the same building can take acrylic over primer.
Silicone On Flat Sections
Low-slope areas beside a mansard or shingle face often take silicone.
Benefits of Coating Your Roof
On the right shingle roof, a coating gives Lancaster owners these gains.
Granules Held
Coating holds remaining granules in place on worn but flat shingles.
Cooler Surface
Light-colored coatings reflect more sun than dark shingles.
More Time Before Reroofing
Reroofing can wait while the shingles stay flat and flexible.
Flashing Rechecked
Every wall, vent, and edge detail gets fixed along the way.
Churches And Offices
Commercial shingle roofs on churches and offices are the usual candidates.
Written Approval
You get the product's shingle approval with your estimate.
Sealed Tab Edges
Resealed tabs and coated edges shed rain cleanly.
Honest Replacement Calls
Roofs past coating get a replacement recommendation instead.

Shingle Roof Coating Steps on Lancaster, PA Buildings
Five steps, with a clear stop point if the shingles are past coating.
- Step 1
Inspect Your Roof
We check shingle flex, granule cover, flashing, ventilation, and the deck from the attic where we can reach it.
- Step 2
Confirm The Product
The coating maker's instructions have to approve it for asphalt shingles on this roof before we go further.
- Step 3
Repair Tabs And Flashing
Lifted tabs are resealed, broken ones replaced, and flashing at walls and vents reset.
- Step 4
Clean Gently
A low-pressure wash removes dirt and loose granules without stripping the shingles.
- Step 5
Apply The Coating
The approved coating goes on at its specified thickness, with care at edges and flashing.
When Lancaster Shingle Roofs Need Another System
Metal and flat sections on the same building take other coatings. These are the other services we offer.
Commercial Metal Roof Coating
Steel roofs that need fastener, lap, and rust repair first.
Silicone Roof Coating
Low-slope and flat sections where water sits after rain.
Acrylic Roof Coating
Sloped metal that drains fast, coated in warm, dry weather.
Spray Foam Roofing
Roofs that need added insulation and one continuous surface.
Shingle Roof Coating Questions for Lancaster Owners
What Does Shingle Roof Coating Cost?
Coating usually runs about $2.50 to $4.00 per square foot of roof, against about $5 to $8 for replacement. Shingle repairs, flashing work, roof size, access, and the coating type and thickness move the figure. Shingle roofs without an approved product get no coating price.
Is Shingle Roof Coating on Commercial Buildings Common?
It is used on a narrow set of commercial roofs, often churches, offices, and mansard faces. The shingles have to be flat and flexible, and the coating has to be approved for them. Strip centers with mansard fronts are another.
Shingle Roof Coating vs Reshingling: How Do You Choose?
Condition decides. Flat, flexible shingles with most of their granules can take an approved coating. Curled, brittle, or bare shingles need reshingling, along with any deck and flashing repairs the tear-off uncovers. We show you the shingles that decided it.
Which coating is appropriate for shingles on a commercial church building?
Only a coating whose maker approves it for asphalt shingles, confirmed in writing. We also look at the shingles' condition, attic ventilation, and flashing. A product made for metal or flat roofs is the wrong choice, and worn shingles point toward replacement.
When should a commercial owner choose new shingles instead of coating?
When shingles curl, turn brittle, or lose large areas of granules. We also check the deck and flashing to size the full job. Any moisture or ventilation problem gets fixed as part of the work, whichever way the roof goes.
A tear-off also exposes the deck for checks.
How should a commercial shingle coating budget be assessed?
Start with compatibility: no approved product means no coating budget. From there, roof size, access, coating type and thickness, number of coats, penetrations, flashing, and repairs set the figure.
Planning numbers run about $2.50 to $4.00 per square foot for coating and $5 to $8 for replacement.
What Is the Best Coating for Asphalt Shingles?
The best choice is one the coating maker approves for asphalt shingles, applied to shingles that are still flat and flexible. Approval comes first, then the shingle condition and ventilation checks. Products made only for metal or flat roofs are left off shingle roofs.
