A leak near equipment may involve the roof curb, a penetration or the equipment itself. Access and coordination with the property team can help narrow the problem.

Write down the unit or curb location and where water appears inside. Ask who will coordinate access and whether the roof crew or another trade is responsible for the suspected detail.

Contact Dekoven Roofing to discuss a commercial roof assessment. Include the building address and the name of the person who can arrange access.

Equipment adds details

Rooftop equipment such as HVAC units sits on curbs and has pipes, wiring and condensate lines that pass through the roof. Each is a place water can enter.

Possible sources

  • Flashing at the curb.
  • Pipe or conduit penetrations.
  • Condensate drainage.
  • The equipment housing itself.
  • Seals disturbed during service.

Coordinate access

Work with the building team and the HVAC contractor so the roofer can inspect safely. Service visits can disturb roofing, so ask the HVAC contractor to report any roof damage.

Document

Record when leaks occur relative to equipment operation. That can help separate roof leaks from equipment issues.

Frequently asked questions

Is it a roof or HVAC problem?

It can be either. Inspect both.

Who is responsible for repairs?

That depends on contracts. Ask.

Can I prevent damage during service?

Ask contractors to protect the roof.
