Where flat roofs leak

Commercial flat roofing in Schenectady leaks at seams, penetrations, and ponding, in that order. EPDM rubber roofing in Schenectady means the black membrane on most buildings here; it opens at glued seams as the adhesive ages. TPO's welded seams last longer but its surface chalks. Water that stands more than 48 hours after rain is called ponding, and it finds every weak seam eventually. The fix is usually drainage, not more patches.

Coat, patch, or replace

A membrane with 5 dry years left coats better than it replaces: roof coating in Schenectady runs $3–$5 a square foot against $9–$14 for new membrane, and the coating resets the clock about 10 years. A roof that's wet underneath is done. Coating over trapped moisture buys nothing, and a core cut (a small plug we cut and check) settles the question for a few dollars instead of a few thousand.

Commercial questions

Do I have EPDM or TPO?

Black rubber, glued seams: EPDM. White or grey, welded seams: TPO. Commercial TPO and EPDM in Schenectady split roughly by age: older roofs rubber, newer ones white. It changes the repair method and the coating chemistry, and it's the first thing we check.

Is ponding actually a problem?

Standing water past 48 hours voids most membrane warranties and works seams open. Sometimes the fix is a $600 drain clearing, not a roof project.

Can you work around my tenants?

Coatings and patches are low-noise and staged by section, because commercial flat roofing in Schenectady is mostly built around occupied buildings. You get the schedule in writing, and the COI goes to your property manager before anyone's on the roof.
