EPDM Commercial roof in Knoxville, TN
Commercial roofs with a lot of equipment or penetrations will have a greater chance of leaking.
This commercial roof has approximately 50 HVAC units floating above the roof. A rail system suspends them, so they do not require roof penetrations. The rail system makes it easier to prevent roof leaks and roof problems.
Unfortunately, this roof still has a leak issue that Litespeed Construction is resolving.
We discovered cracks, holes, and weak points in the EPDM at corners and penetration areas that could be causing leaks.
EPDM flashing tape is coming loose that could be another area that is leaking.
The old sealant is rotted and coming loose and needs to be sealed with a suitable elastomer.
There are a total of about 18 of these areas with failing sealant.
This EPDM patch is coming apart and complete failure is imminent.
This tape joint is loose enough we can stick our hand under it. We should not be able to do this. If it isn’t letting water in now, then it won’t be long before it is.
This section of the roof is very soft and feels like a trampoline when stepping on it. The roof protrudes downward about 5″ when stepping on it.
A.C. unit should be off the roof as the rest of the roof units.
