Peeling
Old Coating Lifting in Sheets
Film that peels in large flakes shows poor original bond, so those areas get scraped to steel and primed again.

Recoats That Start With a Grip Test on the Old Coating
As a Sullivan metal roof coating contractor, we test old coatings and patch mastic for adhesion, remove loose layers, and recoat commercial and municipal steel roofs.
Sullivan Metal Roof Coating Over Old Coatings
Sullivan metal roof coating jobs often land on roofs that were coated or patched before. On commercial, municipal, and industrial buildings in Sullivan County, we find aging coatings, smears of asphalt mastic over laps, and layers of mixed products.
A new coat bonds only as well as the layer under it. Adhesion tests at several spots show which old material holds firm and which peels, and the loose layers come off before any recoat goes on.

Metal Roof Coating Problems on Previously Coated Sullivan Roofs
Roofs with earlier coatings show these four conditions. Each one changes how the recoat gets prepared.
Asphalt Mastic
Black Mastic Over Laps
Tar-based patches bleed through light coatings and stain them brown, so they need a blocking primer or removal first.
Snowmelt
Leaks During Thaws
Melting snow keeps water on the roof for days, and ice at gutters backs it up against old patches until they let go.
Thin Film
Worn-Through Coating
Old film that has eroded down to primer or bare steel along ribs needs spot priming before the full recoat.
Benefits of Coating Your Roof
A properly prepared recoat gives Sullivan building owners four results that a quick top-up over loose film and old patches never does.
New Coat That Stays
Testing and removing loose layers means the recoat bonds to firm material across the roof.
Stains Kept Down
Blocking primer over asphalt patches keeps brown bleed-through out of the new white finish.
Thaw Leaks Sealed
Laps and patches that let go during snowmelt get rebuilt before the coating covers them.
Known Roof History
Adhesion results and photos give the building a record for the next owner or manager.

Recoats add testing to the usual order. These five steps take a previously coated roof to a new, measured film.
Inspect Your Roof
We walk the roof, note every peeling area, mastic patch, and thin spot, and photograph the old coating and its edges.
Test the Old Layers
Adhesion tests at several spots show where old coating and patches hold firm and where they lift off.
Remove What Fails
Loose coating is scraped to a firm edge, failed mastic comes off, and bare steel gets primer.
Block and Rebuild
Asphalt patches get a blocking primer, and laps that leak during thaws get new fabric and sealant.
Recoat and Measure
New coats go on with a compatible product, and wet-film readings confirm thickness across old and new areas.

More metal roof coating answersWhy does a warehouse roof in Sullivan leak when snow melts?
Melting snow holds water on the roof for days, and ice at gutters and drains backs it up against seams and screws. Any small gap then leaks, so sealing laps and screws and clearing drains before winter cuts these leaks down.
Can a new coating go over an old one?
Yes, once the old film passes an adhesion test and is cleaned. Loose areas come off first, and the new product has to be compatible with the old one.
What happens to black asphalt patches during a recoat?
Patches that are firm get a blocking primer so they do not stain the new coating. Patches that have cracked or lifted are removed and the lap is rebuilt.
How do you tell which old coating is on the roof?
A quick test and the look of the film usually show whether it is silicone, acrylic, or another product. That decides which recoat products will bond.
What does a Sullivan metal roof recoat cost?
The calculator range runs about $2.50 to $4 per square foot of roof. The amount of old coating to remove, mastic patches to block or replace, and laps to rebuild set where a roof lands.
How often should a coated roof be checked?
Once a year and after big storms. A walk each spring catches worn spots along ribs, open patches, and clogged drains while they are still small fixes rather than the start of a full recoat.
Is removing all the old coating ever needed?
Only when adhesion tests fail across most of the roof. Then the old film comes off by scraping and washing, the steel is primed, and the job prices like a first coating rather than a recoat.
Can the recoat change the roof color?
Yes, when the new product bonds to the old one. Covering a darker old coating with a light topcoat can take an extra pass for even color, which the scope accounts for.
