I have attached pictures of an area where I am trying to determine where a leak could be coming in? Roof Apex? HVAC weld point?
I bought a recently remodeled house with a sloped asphalt shingle to flat foam roof. The home inspector guessed the roof is approximately five years old.
I have identified and sealed multiple leaks, but cannot pinpoint the source of one. Water is coming through into the attic on the downslope side of the HVAC vent bag during rainstorms.
I have had four roofing contractors out and they have each said they cannot help me. I have also inquired with a HVAC repair company and they said the leak sounds like a roof leak.
I sealed around the base of the HVAC unit and any visible nails/ possible junctures with roof cement/tar, but the leak is as bad as ever.
I would appreciate any suggestions or advice you can offer?
