Our commercial roofing services in Bethlehem cover TPO, EPDM, industrial, and metal roofs, plus full replacement of worn commercial roofs.
Commercial roofing services in Bethlehem come down to four systems. Each card notes the spots where that roof usually lets water in.
Heat-welded white membrane for warehouses, retail, and offices, with seams probed and curbs flashed into the field sheet. Walk pads go on the routes to each unit.
Where Water Gets In
Rubber membrane replacement for offices and older brick buildings, adhered or fastened, with taped laps and new drain flashing. Ballasted roofs are checked under the stone first.
Where Water Gets In
Plant and shop roofs replaced in sections around exhaust, interior humidity, and the production schedule underneath, with equipment isolated before tear-off.
Where Water Gets In
Standing-seam and ribbed panel installs, repairs, and retrofit framing on steel and brick buildings after structural review. Wall flashing is rebuilt where panels meet brick.
Where Water Gets InA quick side-by-side of the four roof systems we install. The inspection on your roof settles the choice for any one building.
| System | Common Buildings | Seams or Joints | Watch For |
|---|---|---|---|
| TPO | Warehouses, retail strips, and offices with rooftop units | Hot-air welded laps, probed after welding | Foot traffic and dropped parts around rooftop units |
| EPDM | Offices and older brick buildings with open roof fields | Primed seam tape rolled into the laps | Lap edges and drain flashing after freezing |
| Industrial Assemblies | Plants, fabrication shops, and process buildings | Membrane and flashing chosen for the exposure | Exhaust residue, equipment curbs, and interior moisture |
| Metal Panels | Steel shops, storage buildings, and pitched wings | Standing seams on clips or lapped ribs | Fasteners, end laps, and flashing at brick walls |
Most owners start unsure. A roof walk and a few cores show which systems make sense for the deck, drains, and equipment you already have.
Schedule Your Free InspectionThe steps stay the same across TPO, EPDM, industrial, and metal work, whatever the size of the roof.
Cores, a moisture check, and a walk of every edge, drain, and curb show what the replacement has to cover. We photograph what we find for the proposal.
The proposal lists the system, insulation, attachment, and each flashing detail in plain terms, along with any allowance for deck repairs found during tear-off.
Roof hoisting spots, debris chutes, and interior protection are placed around how the building runs, keeping entrances and docks clear.
Each roof area opened in the morning is closed watertight by the end of the day, with temporary tie-ins where old and new roof meet.
Seams, drains, and flashing are checked, debris is cleared from the roof and grounds, and the owner walks the roof before we leave.
Replacement is the right call when repairs stop holding. These signs tell us a roof has reached that point.
Cores that find water in many places mean the board under the membrane has to come off. Wet board also hides deck damage until it is removed.
When laps reopen soon after each patch, the sheet itself has aged out, and every new repair joins material that keeps getting weaker.
Rust or rot in the deck needs repair that only a tear-off exposes. Soft spots underfoot near old leaks are the usual warning.
Buildings with stacked old roofs usually need a full tear-off before anything new goes on, since extra layers add weight and hide water.
Loose coping and gravel stop on an aging roof usually travel with a worn membrane, so both are renewed together.
A roof covered in mastic patches at pipes and curbs has more weak points than repairs can keep up with.
Tapered board installed during a replacement corrects slope problems that patches leave behind, sending water to the drains instead of letting it sit.
How owners choose between systems and decide on replacement.
Replace when wet insulation spreads across the roof, when seams fail faster than repairs, or when the deck needs work only a tear-off can reach. A roof with one bad detail and dry layers is a repair job.
Yes, with planning for the season. Winter work depends on safe access and on conditions the chosen system accepts, and each opened area is closed before the crew leaves for the night.
Yes. A warehouse might get TPO on the main roof and metal panels on a pitched wing. Each area gets the system that fits its slope and use.
In most buildings, yes. Sections are opened one at a time, noisy tear-off can be timed around business hours, and interior protection goes up under each open area.
Tear-off depth, insulation, attachment, membrane or panel, flashing at each detail, access and protection, and any allowance for hidden deck damage.
Roof size, the number of layers coming off, and deck repairs set the schedule. The proposal lists sections in order, and weather can shift the dates.
Yes. Twice-yearly walks to clear drains, check seams, and look at curb flashing catch small problems before they reach the insulation.
Usually. We identify the existing system and tie the new area into it with compatible flashing at the joint between old and new.
