Built for office buildings, warehouses and everything between
We replace roofs on office buildings, retail stores, warehouses, industrial facilities, restaurants, multi-family and mixed-use buildings, shopping centers, schools and churches. Each gets a membrane matched to its use and equipment load.
TPO
Heat-welded seamsTPO uses heat-welded seams and reflects heat well, so it runs energy efficient.
EPDM
Adhered or fastenedEPDM is a rubber membrane, installed fully adhered or mechanically fastened.
PVC
Heat-welded seamsPVC is heat-welded too, and holds up against grease and chemicals better than most.
Modified Bitumen
Torch or self-adheredModified bitumen goes down torch-applied or self-adhered, in layers.
Replacement is also the time to deal with an aging skylight. Our commercial skylight replacement page covers that alongside the membrane work.
Two paths, and the roof itself decides which one
Commercial owners face one real decision: full tear-off or roofing over what is already there. We inspect first and tell you honestly which path fits. Roofing over is faster, but code and condition do not always allow it.
- Condition of the existing deck and membrane
- Building code limits on how many layers are already up there
- Rooftop equipment that needs lifting, cutting around or resetting
Costs differ between the two. Our tear-off vs roof-over cost breakdown walks through what drives the price either way.
Slope and drainage decide how long the roof lasts
A low-slope roof still needs slope. Poor drainage lets water pond after storms, and standing water breaks a membrane down faster than sun or wind alone. We check drains, scuppers and slope during inspection, not after the membrane is down.
Rooftop HVAC units, condensers and vent stacks stay operational as much as possible, planned around your equipment instead of shutting it down.
A schedule built around your operating hours
Your building does not stop running because the roof is being replaced. We phase the work by section, with off-hours and weekend scheduling for buildings that cannot host crews during business hours.
- Phased sections so only part of the roof opens at once
- Off-hours and weekend work for occupied buildings
- Continuous waterproofing through every stage of tear-off
Commercial roof replacement, answered plainly
How long does a commercial roof replacement take?
A Brooklyn replacement typically runs a few days to a couple of weeks, depending on square footage, access and whether it is a full tear-off or a roof over. We confirm a firm timeline after inspecting.
Do you offer roof coating and maintenance after replacement?
Yes. We offer coating and maintenance plans once the new roof is installed, to protect the membrane and extend its lifespan.
Can you match my building's insurance documentation needs?
Yes. We provide the scope of work and completion records most insurers and property managers ask for.
Do you work on occupied buildings?
Yes. Phased scheduling, off-hours work and continuous waterproofing let us replace a roof while your building stays open.
