As a York shingle roof coating contractor, we coat commercial shingle sections that still lie flat and have an approved coating, and say so when they need reshingling.
York shingle roof coating has a narrow gate. Compare your shingles with both cards before planning anything.
Shingle sections in decent shape, with an approved coating, can be coated to keep them in service longer.
Shingles in this column need reshingling; coating would only cover the problem.
Shingle sections on commercial buildings show clear signs of whether coating is still an option.
Some granule loss comes with age. Heavy buildup in gutters and bare patches on the tabs tell us the shingles are near the end.
Tabs that curl will not lie down under coating and keep lifting in wind. Those sections usually need reshingling.
Gaps where tabs blew off expose nails and underlayment. They get replaced with matching shingles before any coating plan.
Water marks inside a mansard wall or soffit mean the shingles or flashing are letting water in. Call so we can find the entry point.
Joints between a shingle mansard and the flat roof behind it are common leak points. We check that flashing on every inspection.
Shingle coating on commercial buildings follows a short list of builds.
Only coatings the shingle and coating makers support for that shingle go on, applied at their listed rate.
Fabric and brush coats at the mansard-to-roof joint, valleys, and penetrations before the field coat.
When the shingles fail the inspection, new shingles replace them, and the rest of the roof is coated as planned.
Tab-by-tab checks of curling, granule loss, and nail hold across the section come before any product is chosen.
Coating binds loose granules on aging tabs, which slows the bare spots that let sun break down the asphalt.
Light coating colors cut heat on dark shingles that face the afternoon sun.
On flat-lying shingles, coating can push a reshingling decision out while other roof work on the building gets planned.
Reinforced coating at the joint between the shingle face and the flat roof closes a spot that leaks on many older buildings.
Where shingles are still in good shape, coating does a few useful things.
Missing tabs leave nails and underlayment open to rain. Call and we will check the section and patch it before deciding on coating.
Four steps, with a product check before any price.
Tabs, granules, nails, flashing, and the deck under soft spots get checked, and we look for interior stains below the shingle section.
Approval from both the shingle maker and the coating maker is checked before pricing. Without it, we recommend reshingling.
Missing tabs are replaced, flashing is resealed, and the shingles are cleaned gently so granules stay put.
Coating goes on at the rate the maker lists, with extra attention at valleys, flashing joints, and edges.
Notes on the tabs and flashing joints to watch go to you, and an inspection is set so curling or granule loss gets caught early.
Most buildings with shingle sections have other roof areas too.

Small sections still need the same compatibility review and access setup, so the per-foot cost can run higher than on a big roof. Coating plans at about $2.50 to $4.00 per square foot of roof and replacement at about $5 to $8; flashing and repairs move the number.
On shingles that qualify, coating plans at about $2.50 to $4.00 per square foot of roof, compared with $5 to $8 for replacement. That gap matters only when the shingles pass the condition check; coating failing shingles just delays the reshingling bill.
The shingles decide. Flat-lying tabs with most granules, a dry deck, and an approved product can be coated. Curled, brittle, or bald shingles, or a wet deck, mean reshingling, because coating them would only postpone repairs the roof already needs.
The reviewing authority decides what review a project needs. Pennsylvania’s Uniform Construction Code sets the statewide framework, and we give the reviewer a clear description of the coating and any shingle replacement involved.
When the shingles are no longer a stable covering: broken or missing tabs, lost attachment, or wet decking underneath. Coating needs a supported product and shingles in good shape, and using it to put off repairs the roof already needs only moves the problem down the road.
The one both makers support for your specific shingle. We check that compatibility before talking about application, and if no supported product exists or the shingles have aged out, we tell you to address the shingles themselves.
Start with the shingle maker and the coating maker. Both have to support that combination for your shingles and roof conditions; if either one says no, or the shingles have aged out, the better plan is to repair or replace the covering itself.
Light grays and tans cut heat on south and west faces while staying close to the original look. The color has to come from the approved product line for that shingle, so we show you those options after the compatibility check.
