Two Roofs Stacked Up There
An earlier owner covered an old roof instead of removing it. Cores find both, and the building office decides whether code allows one more.

Old Layers and Sullivan Commercial Roofing
Sullivan commercial roofing decisions start below the surface. How many layers are up there decides whether a new roof can go over or the old ones come off.
Older retail and municipal roofs often hide a second roof under the first, plus years of patches. Cores cut at the field, drains, and walls count them and show whether the insulation is dry.
One dry layer can carry a recover with new cover board. Several layers, or any wet boards, point to tear-off, and code limits how many layers a roof can carry.
- Cores at field, drains, and walls
- Layer count written into the scope
- Wet boards removed before anything goes over
- Permit office confirmed before work
Roof Conditions
Commercial Roofing Problems on Sullivan Buildings
Roofs with history hide problems under the surface. These four come up most often in Sullivan.
Wet Boards Under a Dry Surface
A sheet that looks fine can sit over soaked insulation from an old leak, adding weight to the deck.
Patches in Three Materials
Repairs in tar, tape, and coating overlap on the same seam, and none of them bond well to the others.
Public Buildings With Open Hours
Municipal and retail buildings stay open during work, so noise, entrances, and parking need planning.

Sullivan Commercial Roofing Questions

Buildings outside the towns we list can call or send a message, and we will say whether we can reach them.
Permits
Who handles commercial roofing permits for Sullivan buildings?

Cost
What drives Sullivan commercial roofing cost?
Whether the old layers stay or go makes the biggest difference.
A recover over one dry layer skips most of the tear-off, while two layers or wet boards add removal and deck repair. Size, system, and curbs add the rest.
Local
Where can I find Sullivan commercial roofing near me?
Call with the building address.
We set a roof walk with core cuts, then tell you whether the roof can take a recover or needs a tear-off.
Hiring
Is there a commercial roofing contractor near Sullivan for public buildings?
Municipal and other public buildings get work planned around open hours, entrances, and parking.
Boards and managers get the layer count and core photos in writing to back the decision.
Layers
How many roof layers can stay under a new roof?
Code sets a limit on roof layers, and the local building office applies it.
We count the layers with cores and confirm the limit with that office before choosing recover or tear-off, so nothing goes on that has to come off later.
