Quick Answer
Commercial flat roof leaks aren’t always caused by the area where water is dripping inside your building. Water can travel several feet before it becomes visible. That’s why professional inspections are critical for accurately identifying the source of the leak and recommending the right repair.
We provide free annual inspections and can identify areas that need to be repaired.
Flat roof repairs include:
- EPDM or Rubber
- TPO
- PVC
- Built up roofing (BUR), also known as hot tar
Flat roof problems are like a puzzle; they are often not straightforward. Why? Water is cohesive (or sticky) and will follow paths until it begins to drip. You may have a leak that shows up 10 feet from where it originated. Our highly experienced repair technicians will be able to identify the problem.
Common causes of roof leaks are:
- Membrane Puncture
- Roof Drain Backup
- Clogged Scuppers or Downspouts
- Ice Dams
- Membrane Fatigue
- Flashing Failure
Common non-roof-related reasons for ceiling leaks include:
- HVAC Penetrations
- Ice Condensation
- Poorly Installed Vents
⭐ Building Owner Tip
Building Owner Tip: A ceiling stain doesn’t always indicate where the roof is leaking. Water often travels beneath the roofing system before it becomes visible inside the building. A professional inspection can help locate the true source of the problem and prevent unnecessary repairs.
