Roof leak, or maybe not. Need a good commercial GC in Houston

[Courtney Nguyen]

Hi BP,

Anybody can recommend a good commercial GC in the Houston area?  We had a roof leak back in September at our end cap unit which is a coffee shop (retails strip, 9 tenants, building is only 4 years old) and I reported it to our roof warranty company (Carlisle).  They sent a roofer and that man said roof is good, the issue was with poor installation of HVAC system.  I had an HVAC guy came and he said nothing is wrong with the HVAC system.  So I hired a commercial inspector to inspect the whole roof/hvac system and he said there is 1 boot over the unit that had the leak the AC drain was poking into the vent boot and that is a no no, and the seal was broken.  So I had both the roofer and the plumber guys came to replace the boot and redirected the AC drain pipe to a different route.  We thought that fixed the issue.  But no, over the weekend we had heavy rain and the coffee shop had a leak again, at the exact same spot!  So at this point I am not sure if it's a roof issue or something else.  I already reported the leak to roof warranty company (normally they send an 'authorized roofer' to come and look) but at the same time I feel like maybe I need a good GC who has good understanding of construction to come and look at this and find the source of the leak.  That's why I ask for recommendations of a good commercial GC.  Unless you guys think I need somebody else to at this.

Any tips/advice is greatly appreciated!  Thanks in advance.
