Short Curbs After Past Reroofs
Each reroof raised the roof but not the curbs, so flashing now stops only an inch or two above the surface. Snowmelt and driving rain top that low flashing and run inside the curb.

Roof Replacement for Buildings With Many Rooftop Units
Brookhaven commercial roofing often means working around equipment: we replace roofs on buildings with rooftop units and plan the HVAC work first.
Brookhaven Commercial Roofing Around Rooftop Units
On Brookhaven commercial roofing jobs with rooftop units, the equipment plan is written before tear-off starts.
A new roof usually sits higher than the old one because of added insulation. That shrinks the flashing height at every unit curb, so some curbs need raising and some units need lifting.
We list each unit, decide what happens to it, and book the HVAC contractor for those days. When roofing reaches a unit, the disconnects, lifts, and curb extensions are already lined up.

Rooftop Unit Problems Behind Commercial Roofing in Brookhaven
Units cause more roof leaks than any other detail. These are the ones we find most.
Condensate Lines Draining on the Sheet
Units drip condensate onto the membrane, staining it and keeping one spot wet all summer. Algae grows on that wet patch and holds even more water against the seams.
Cracked Flashing at Curb Corners
Corners at unit curbs take the most movement and crack first, letting water in beside the unit. Preformed corners on the new roof replace the folded and patched ones.
Wear Along Service Paths
Technicians walk the same path to each unit, and the membrane wears thin along it. Scuffed seams and small cuts collect along that line first.
Abandoned Curbs and Openings
Old curbs from removed units stay on the roof as leak points nobody maintains. Many still have open ducts under their caps that let rain into the building.
Water Held Behind Units
Large units across the slope trap water on their uphill side. That trapped water finds any small opening in the curb flashing nearby.

Curbs Tall Enough to Flash
Curbs are raised to give proper flashing height above the new insulation. Units are reset level on the raised curbs by their own trade.
Old Openings Closed for Good
Unused curbs come out and the deck is patched, removing leak points. The patched deck gets insulation and membrane like the rest of the roof.
Condensate Piped to Drains
Condensate lines are routed so water stops sitting on the membrane. Lines are strapped on supports so they stay off the membrane.
Walkways to Each Unit
Walkway pads mark the service route and protect the sheet underfoot. Technicians reach every unit without crossing open seams.

Brookhaven Rooftop Unit Questions
What owners ask about units, curbs, and HVAC timing.
Coordination
Do Brookhaven Rooftop Units Need Coordination During a Roof Replacement?
Yes, whenever the new roof changes flashing, access, or roof height at a curb. We list the equipment tasks before removal reaches those areas, and the HVAC trade handles disconnects and resets, with clear responsibility for putting both roof and unit back together.
How Is HVAC Work During a Roof Replacement Scheduled?
We give you and your HVAC contractor a section schedule. Units come off line only on the day roofing reaches them. Disconnects, lifts, and restarts are booked ahead, so the crew is not waiting on equipment.
Curbs
What Does Rooftop Unit Curb Flashing Include?
Base flashing wrapped up each side of the curb, preformed corners, and a cap or counterflashing at the top under the unit. It must rise far enough above the finished roof to keep water out during heavy rain and snowmelt.
When Is Raising Curbs for New Insulation Needed?
When the new insulation leaves too little flashing height at the curb. We measure each one. Short curbs get extensions, which often means lifting the unit for a day.
Old Equipment
What Happens to Curbs From Removed Units?
We take them out during the reroof, patch the deck, and roof over the opening. Leaving them in place keeps a leak point nobody services.
Can Condensate Lines Drain Onto the New Roof?
We route them to a drain or onto a protected pad instead. Constant drips wear the membrane, grow algae, and keep one spot wet.
