A commercial roof inspection checks the membrane, seams, flashing, drains, rooftop equipment curbs and signs of wet insulation, then documents everything with photos. On Staten Island, flat commercial roofs should be inspected twice a year (spring and fall) and after major storms, so small repairs never turn into replacements.

What a commercial inspection covers
Membrane & seams
Splits, punctures, shrinkage, open seams and sun damage on TPO, PVC, EPDM and modified bitumen.
Drainage
Drains, scuppers, gutters and ponding areas. Standing water is the fastest way to shorten a roof's life.
Flashing & parapets
Wall and parapet flashing, coping, counterflashing and edge metal. Wind and salt air near the water wear these first.
Penetrations & equipment
HVAC curbs, vents, pipes and anything bolted through the roof.
Insulation moisture
An infrared (thermal imaging) moisture scan that maps wet insulation under the membrane, plus the soft spots and blisters that point to it. Wet areas are marked on the photo report, so you know exactly how much roof is affected.
Safety & access
Hatches, ladders and walkway pads, so service techs don't damage the roof.
Why regular inspections pay for themselves
A commercial flat roof should last 20–30 years. Many don't, because small problems like a clogged drain, a lifted seam or a cracked boot around a vent go unnoticed until water reaches the ceiling tiles. Caught early, those fixes usually fall in the $400–$1,500 range. Found after the insulation is soaked, they can mean a full replacement.
An inspection also gives you something you can't get from a ground-level look: a record. Insurers, lenders and boards all want to see the roof's condition on paper, with dates and photos.

(929) 370-1552Commercial roof inspection: common questions
How often should a commercial roof be inspected?
Twice a year: in spring to catch winter damage and in fall before the cold season. Also after nor'easters, major storms or any rooftop equipment work.
What do I get after the inspection?
A photo report showing the roof's overall condition, every issue we found and where it is, and a prioritized list of repairs with prices, so you can budget and get approvals.
Can an inspection help with insurance or buying a building?
Yes. A documented condition report is useful for insurance claims after storms, for due diligence when buying a building, and for capital planning.
Will you push us to replace the roof?
No. Most roofs we inspect need maintenance and a few repairs, not replacement. If a section is beyond repair, the photos will show you why.
Get an honest answer about your roof.
Free inspection, photos of what we find and a written quote. If it only needs a repair, we'll tell you.
