A lifted lap on a Hampton commercial or institutional roof is a weak spot that rain finds quickly. Water gets in where two sheets of membrane have separated, even if the roof on either side is still sound. We diagnose and repair commercial membrane roofs in Hampton and across the Chesapeake, VA area. We look at the actual seam and the roof around it before choosing a repair, rather than guessing from how it looks. The repair has to bond to solid material and sit on dry insulation. If the roof is failing in many places, we'll talk about replacement instead.
Every Hampton building has its own access and operating needs. Before we come out, the building contact tells us which rooms need protection, what equipment is nearby and when we can work. Send us when the leak happens and photos of the inside if you have them, so we can compare them with what we find on the roof.
On site, we inspect the laps and nearby flashing and photograph the opening or failed seam. Our report separates what we confirmed from what needs a closer look. That lets you approve a clear, limited repair now, with a path for follow-up if we find hidden damage once the roof is opened.
Why laps lift and how we fix them
A seam can lift while the membrane next to it is still well attached. Wind catching an open edge can peel it back further over time. We check the seam, the membrane around it and the surface it sits on. Old sealants and patches often hide damaged material and make the good membrane harder to find. We identify your roof type and use repair materials that bond to it. Putting another layer over a lifted lap won't fix loose or wet material underneath.
Our commercial roof repair crews rebuild lifted laps based on what we find. Buildings in Newport News get their own inspection. If people have been walking or working near the seam, there may be damage beyond the obvious spot, so we check nearby seams too. If a condensate line or other equipment is part of the problem, that's for your HVAC contractor. We repair the roof based on what's actually there, not on what was done last time.
Checking the insulation under the seam
Water through a lifted seam can soak the insulation below, sometimes farther than the visible gap suggests. We test suspicious areas using methods suited to your roof. An infrared scan can help find likely wet spots on the right roof, but we confirm them with core cuts, since equipment and layers can affect the readings. If we still have questions about an area, we note it for further testing. The new seam needs dry, solid insulation underneath.
Our infrared moisture survey helps us target testing. Buildings in Suffolk get their own testing. We separate confirmed wet areas from areas we're still unsure about. Dry insulation stays where the repair method allows. If we find more damage once the roof is opened, we show you where and explain the fix before going further. Covering wet insulation won't give the new seam the support it needs.
We also check where the new insulation will meet the existing roof. That transition needs to be level and well supported. Flashing nearby may need new backing too. You'll hear about those details before approving the repair.
When the leak comes back
If a leak shows up again near an old patch, it might be coming from a different spot. We inspect nearby seams and equipment and compare them with when the leak appears. Water can travel through the roof layers before dripping inside, so the stain helps us know where to look, not exactly where to cut. If a condensate drain or equipment is leaking, your HVAC contractor should handle it. We'll tell you if that's the case.
Our roof leak repair work finds where the water is getting in now. Old sealants around the seam may hide the real problem. We look for sound membrane the new repair can bond to. If we're not sure about the insulation underneath, we say so before opening the roof. Photos show you how the leak inside connects to what we found on the roof. A coating or surface patch only makes sense if the material underneath is good. If spot repairs won't hold, we'll recommend a larger repair or replacement.
Getting ready before we open the roof
A good seam repair needs the right materials and a properly prepared surface. We identify your roof type before choosing how to clean and join the seam. We check moisture and temperature at the repair area, since every product has its own requirements. If the surface needs more time to dry, we wait. If an HVAC unit needs to be moved or a curb needs new backing, that trade needs to be scheduled first. Having materials on site doesn't help if a curb isn't ready.
Our penetration and skylight flashing work often goes along with seam repairs. Damaged backing near a pipe or curb can change the size of flashing parts, so we measure before ordering them. If conditions aren't right, we explain what needs to change before we continue. Temporary seals tie into the existing roof around the opening. We plan a safe stopping point before opening a larger area. Each day's work includes everything the repair needs to stay watertight.
Working over occupied buildings
Removing damaged membrane opens the roof over the space below. The building manager tells us which areas need protection and how materials can get to the roof. If ceilings or electrical equipment got wet, your maintenance staff or electrician should check them. We seal the open area before the end of each day. New flashing and materials are ready before we start. If we find more damage, we explain it before expanding the repair. A sealed roof doesn't mean the ceiling or finishes inside are ready to repair.
For roof work over occupied buildings in Hampton, we plan around the people inside. For public and government buildings, the facility contact sets the access rules. When we're done, you get a record of the repaired seams and replaced insulation. HVAC crews get tips for avoiding damage to the repair. Interior contractors can move ahead once the roof is done. You can report leaks nights, weekends and holidays, and we'll confirm timing based on your address. If new damage shows up later, we inspect it fresh.
Commercial Roofing Questions
What makes a lifted-lap repair last?
Bonding the repair to clean, sound membrane, sitting it on dry insulation and using materials that match your roof type. Covering a lifted seam with sealant usually doesn't last.
Does the length of the lifted seam tell you how much insulation is wet?
No. Water can spread beyond the visible gap. We test the insulation around the seam to find the wet area before deciding what to replace.
What if a leak shows up near an old repair?
It may be a new leak from a different spot. We inspect nearby seams and equipment and compare them with when the leak happens before deciding on a fix.
What needs to be ready before you remove damaged membrane?
Materials, flashing parts and any HVAC or curb work, plus a plan for sealing the roof that day. We also check that the surface is dry enough to work on.
How do we keep the repaired seam from getting damaged later?
We give HVAC and maintenance crews a record of where the repair is and tips for working around it. If new damage happens, we inspect it fresh.
Lifted seam on a Hampton roof?
Send us the Hampton building address, when the leak happens and any access restrictions. We'll find the open seam and send photos with a short explanation of the repair.
