Single-ply work we do
Four jobs on membrane roofs
Your roof needs one of these, and each is quoted separately.
New installation
Insulation, membrane and flashing on a bare or new deck.
Replacement and re-roofing
We tear the failed roof off to the deck, then lay new insulation and membrane.
Repair
Fixing open seams and punctures on your existing membrane, plus flashing at drains and curbs.
Inspection
Seam probing, then a written condition report before you decide to repair or replace.
TPO, EPDM or PVC for your building
Which membrane fits your roof
The right sheet depends on sun exposure and on what the building vents onto the roof.
| Membrane | Our usual pickTPO | EPDM | PVC |
|---|---|---|---|
| Seams | Hot-air welded | Taped or glued | Hot-air welded |
| Handles best | Sun and cooling load | Cold and flexing | Grease and chemical exhaust |
| Suits | Warehouses, retail | Apartments, multi-family | Restaurants, mixed-use |
| Typical attachment | Mechanically attached; how we install TPO start to finish | Fully adhered | Mechanically attached or adhered |
Fastened, seamed and insulated right
How we fasten, weld and insulate the sheet
Fully adhered membrane is glued to the cover board edge to edge, which suits concrete decks and roofs exposed to hard wind. Mechanically attached sheets are screwed through plates into steel or wood decks, with tighter rows at corners, where uplift peaks.
We weld every seam with hot air, then probe it once cool. Polyiso insulation underneath sets the R-value. Each commercial single ply roofing job follows the manufacturer's spec, so the manufacturer warranty holds. What a long-term commercial warranty actually covers is worth checking before you sign.
Single-ply roofing FAQ
Before you sign for a membrane roof
Can a new membrane go over the existing roof?
Often yes, when the deck carries one roof and the insulation is dry. Core cuts tell us. Wet insulation or two existing roofs means a tear-off.
How long does single-ply last on a Queens building?
Well past its warranty term, with seams welded right and a yearly inspection. Thicker 60 or 80 mil sheets outlast 45 mil around rooftop units.
Can tenants and businesses stay open during the work?
Yes. Single-ply goes down with hot-air welders and adhesive, with no kettles or torches. We work in sections and seal each one watertight at the end of the day.
