Many Leaks are Caused by Mechanical Rooftop Equipment
Who’s to Blame? Don’t Blame the Roofer
It is estimated that roughly 30% of leaks from commercial buildings originate from HVAC equipment, while only 20% of those leaks are actually roof related.

Common leak spots for HVAC units
Holes and loose edges on HVAC fresh air intake hoods
Holes and poor weather stripping in HVAC air intake panels.
Loose or missing filter access panels on HVAC units.
Poorly designed filter access covers on HVAC ductwork.
Improperly sealed joints, seams and holes on HVAC ducts
The Roof is a Working Platform
For most construction trade – electrical, mechanical, plumbing, etc.
And many times the equipment itself is not waterproof. This often leads to roof leaks. Tenants incorrectly assume that all wet ceiling tiles mean roof leaks, but in reality it is often the rooftop equipment. So guess who gets the blame? Of course the roofer is called, while the mechanical, plumbing, and electrical contractors remain unaware of the equipment problems.
