Danville Commercial Roofing Contractor
Recover Or Tear-Off For Roofs Hiding Several Old Layers?
As a Danville commercial roofing contractor, we replace roofs on older offices, churches, and shops, starting with cores that show how many layers sit on the deck.
Danville Commercial Roofing On Older Buildings
Danville commercial roofing on older buildings starts with a count. Many roofs here were covered more than once, and that history decides the plan.
Cores through the field show each layer, what it is made of, and whether it is wet. Code caps how many layers a roof can carry, so a stacked roof comes off to the deck before anything new goes on.
Old wood decks get checked from below and at the cores. Rotted boards are replaced during tear-off, and churches and offices are covered inside before each section opens.
- Cores count every layer
- Wood deck checked and repaired
- Sanctuaries and offices covered inside

Commercial Roofing Systems For Danville Properties
Older buildings in town take these systems once the deck is ready.
TPO Roofing
Welded white sheets on larger flat offices and newer commercial buildings, fastened through new board once the old layers are off.
EPDM Roofing
Rubber suits churches and older offices with many walls and steps, since it flexes where old brick and new roof move differently.
Industrial Roofing
Shops and light plants with exhaust get matching membrane, raised curbs, and walkway pads to every unit.
Commercial Metal Roofing
Metal panels fit pitched church and shop roofs, with snow guards set over entrances and walkways.

What owners of older Danville buildings ask us.
Layers
Do you install roofs on Danville commercial buildings?
We roof offices, churches, shops, and light industrial buildings in town. Older buildings often carry several layers, so we check underneath before deciding whether a recover is possible, then choose TPO, EPDM, or metal for that roof.
How many roof layers are allowed on a commercial building?
The building code limits recovers, so a roof that already has its maximum number of layers gets torn off to the deck. Your local building office can confirm the rule for your building. Cores at several spots tell us exactly what you have, layer by layer, before anyone prices a recover.
Older Buildings
What does an older commercial building roof replacement involve?
Expect cores, a deck check from below, tear-off in sections, repair of soft boards, new insulation, membrane or metal, and new parapet flashing with coping. Interior covers protect rooms below each open section, and older scuppers and gutters are rebuilt so water leaves the new roof cleanly.
How is a church roof replacement scheduled?
Work avoids services, weddings, and funerals, with sanctuary areas covered inside before the section above opens. Steep sections over the sanctuary usually take metal panels with snow guards over entrances; low roofs over halls and classrooms take membrane. The church gets a calendar of which roof is open each week.
Decks
What if the wood deck is rotten under a Danville roof?
Rotted boards are cut out and replaced during tear-off, before insulation goes back down. The scope lists a per-board allowance, so deck work is priced before it starts, and you see the damaged sections before they are covered. Sagging spans get checked for the joist below too.
