Shops, offices & low-slope roofs
Commercial roofing in the Lehigh Valley
Repairs that keep the business open, and replacement planned around it. Low-slope and pitched roofs on commercial buildings in Allentown and nearby.
Low-slope roofs fail at the details
Most flat and low-slope roofs do not wear out evenly. Trouble tends to start where the membrane is interrupted or under stress:
- Seams and laps that have opened up
- Curbs around rooftop units, vents and hatches
- Drains, scuppers and gutters that are blocked or undersized
- Parapet walls, coping and the flashing where roof meets wall
- Areas where water ponds for days after rain
Catching these early is usually far cheaper than replacing wet insulation and decking later.
Planning work around your business
Commercial work starts with practical questions: what is under the leak, how staff, customers and deliveries get in and out, where materials can be staged, and which hours are quiet. If you lease the building, it also helps to know who is responsible for the roof under the lease before anything is scheduled.
Regular checks cost less than emergency calls
The National Roofing Contractors Association recommends inspecting roofs at least twice a year, typically in spring and fall, and again after severe weather. A check after the leaves come down and before winter is especially worthwhile in the Lehigh Valley, where repeated freezing and thawing finds any weak seam.
Commercial buildings with pitched roofs, slate, gutters or custom metal are covered too. See slate and tile roofing and sheet metal and flashing.
FAQ
Commercial roofing: common questions
Can a commercial flat roof be repaired instead of replaced?
Often, yes. If the leaks come from seams, flashings or drains and the insulation underneath is still dry, targeted repairs can buy years of service. Widespread wet insulation, repeated leaks across the roof or a membrane that is brittle everywhere point toward replacement.
How often should a commercial roof be inspected?
At least twice a year, usually spring and fall, plus after major storms. That is the schedule the National Roofing Contractors Association recommends, and it lines up well with Lehigh Valley seasons.
What causes ponding water on a flat roof?
Blocked or poorly placed drains, a deck that has sagged, or a roof built without enough slope. Water still standing a couple of days after rain adds weight and speeds up wear, so it is worth having looked at.
