Most commercial roof leaks aren't a worn-out roof — they're one failed seam, one flashing, one drain, one curb. We find which, fix it properly, and hand you photos of both the problem and the repair.
A TPO or membrane roof rarely fails in the middle of the field. It fails at the joints, the edges, and everything bolted through it — and on Grand Valley buildings, sun and hail find those details first.
Welded seams fail at their ends and at T-joints first, where three layers meet. A proper re-weld is a real repair with a real service life — not a smear of mastic that buys you one more season.
Where the membrane turns up a wall and terminates is where a great many commercial leaks actually begin. Termination bar, counterflashing, and a top edge that isn't just trusting a bead of sealant to last.
Internal drains and scuppers fill with gravel, leaves, and whatever the wind delivered. Water that can't leave gets heavy and goes looking for the nearest weak seam instead.
The HVAC unit gets serviced twice a year. The flashing skirt around its curb gets serviced never. Curb corners, condensate lines, and the sheet metal nobody has looked at since it went on.
Conduit, gas line, and the sleeper blocks holding them off the roof, which shift slightly every time it heats and cools and grind the membrane underneath. Pitch pans — the sealed boxes poured around odd-shaped penetrations — dry out and shrink until there's a gap at the top.
Service techs walk the same line to the same unit for years. Add a dropped tool or a dragged ladder and you get a puncture. Sometimes the right fix isn't only the patch — it's a walk pad so it stops happening.
On a commercial building you're usually not the only person who needs to understand what happened up there. An owner, a landlord, a board, or an adjuster is going to ask — so we document the repair the same way we document a storm claim.
If the inspection turns up a roof that's failing in too many places to keep patching, we'll say so — and replacement is its own conversation. If storm damage is involved, the claim process works much the way it does on a house. Still working out what your building needs? The commercial roofing overview lays out both paths.
Call and tell us what you're seeing and where. We'll get someone on the roof to find the source and, where we can, stop the active water while we're up there. What we won't do is guess from the ground — the spot on your ceiling is very often not under the hole.
Water lands on the membrane, travels between layers or along the deck, and comes through at whatever low point it reaches first — sometimes many feet away. So we work from the failure points outward: seams, flashings, drains, curbs, and penetrations uphill of where you're seeing it, rather than opening up the roof directly above the stain.
It can absolutely be repaired. Single-ply membrane is designed to be welded, so a properly prepared and re-welded seam or patch becomes part of the sheet rather than a bandage sitting on top of it. Whole-roof replacement is the answer when the failures are everywhere, not when there are three of them.
Almost never for a repair. Most of the work happens on the roof rather than inside, and we'll agree on access and timing before we start so your customers or tenants aren't walking around a ladder. Tell us your busiest hours and we'll plan around them.
It can, depending on who manufactured the membrane and who holds the warranty — some require that work be done a particular way or by a particular contractor. If your roof is still under a manufacturer warranty, bring us the paperwork before anything is touched and we'll work out what it allows.
When the same roof keeps failing in new places rather than the same one, and especially when the insulation underneath has taken on water. At that point each repair is buying a shorter and shorter reprieve, and the math turns. We'd rather tell you that than keep selling you patches.
