Rooftop Equipment and Penetration Inspection, explained.
Every hole in a roof is a leak waiting to happen. HVAC curbs, refrigerant lines, conduits, gas pipes, vent stacks, roof hatches and satellite mounts all penetrate the membrane and depend on flashing, sealant and good workmanship. Service technicians can also damage the roof by walking on it or dropping tools.
We inspect each curb and penetration: flashing laps, sealant, fasteners, pipe supports, pitch pockets and the membrane around them. We note damage from foot traffic and equipment service. The report lists each penetration, its condition and its repair priority, so the weakest links are fixed first.

Why do penetrations leak?
Sealants age, flashings loosen and movement from equipment and weather opens gaps.
Should service technicians avoid walking the roof?
Walk pads and set paths reduce damage. We can suggest places for them.
Can a new unit damage the roof?
Installation can puncture or disrupt flashing, so inspection after installation is wise.
