Commercial Roofing Services in Paducah

Replacement makes sense when the membrane or panels are worn across most of the roof, the insulation underneath is wet, or repairs keep failing in new places. A roof walk shows it: seams opening across the field, blisters and shrinkage pulling flashing off walls, soft spots underfoot, or rust holes at panel ends.

The old insulation decides. Dry, firm boards under a single roof layer can take a recover, which adds a layer and raises the edges and curbs. Wet boards, or a roof that already has two layers, call for tear-off down to the deck, which also opens rusted deck sections to repair.

Wet boards are removed and new polyiso goes in at the level the commercial energy code sets, often with tapered sections that pull water toward drains. Boards are staggered so joints never line up, cover board goes over the top, and crickets sit behind wide curbs. Edge metal and curb flashing are built to the new height.

Yes. Work moves section by section, and each one is sealed watertight before the crew leaves for the day, with a temporary tie-off holding rain out of the next area. Lift spots stay clear of entrances, doors under active edges get covered walkways, and unit shutdowns are timed with building staff.

A full replacement rebuilds the perimeter and every detail along with the membrane: edge metal rated for wind uplift, coping caps reset on continuous cleats, counterflashing set into reglets in masonry walls, new or retrofitted drain bowls and strainers, and scuppers or gutters sized for heavy storms. Corners get the tightest fastening.

Six layers do the work: the structural deck, a vapor retarder, insulation, cover board, the membrane or panels, and the edge metal and flashing that close the perimeter. Replacing a roof means choosing each of those layers, and the edges deserve as much attention as the open field because most leaks start there.

If the roof looks flat from the ground but still drains, it is low-slope and takes a membrane such as TPO or EPDM. Visible pitch with panels running from a ridge cap to the eave means metal works. Ponding rings around drains or along the eave show where slope is too shallow for the covering on it.

Spring through fall gives the most working days, since adhesives, primers and seam tape all have minimum temperatures. Summer brings long days and quick adhesive set but a hot membrane, while fall offers steady weather with short days and morning dew. Winter jobs lean on fastened sheets and welded seams that need less adhesive.
