WHAT OUR CLIENTS HAVE TO SAY

ALISON’S TESTIMONIAL

 

On November 30, 2017, Julian Valdez & Eric Quinones came out to 720 Presidio Avenue to do some work on a problematic roof.  They did an AMAZING job.  Everything about the process with your company was great.

 

When Mousa called me to schedule the repair, he listened to all of my concerns (which were many) and answered all of my questions.  I told him that the particular roof had been reroofed three years ago and then repaired, but was still leaking.

I explained the many different theories that had been presented about the leak by different roofers and my frustration.  He was knowledgeable and patient.  He let me know that your crew would look into all of my concerns.

 

Julian and Eric came out and were both very pleasant.  Mousa contacted me after a few hours to let me know that they’d spent quite a bit of time “thinking like water” and had done lots of testing.  They thought they’d identified the problem – a portion of the roof had not been properly adhered and water was entering.  Julian and Eric took videos and photos making it extremely  easy to understand the cause of the problem.  I was somewhat irritated that no one else had been able to identify the problem – which seemed glaringly obvious once they discovered it – but thrilled that your crew could help me.

 

They repaired the problem and Mousa told me that he wanted to wait until we had a good rainstorm to confirm that he problem had been resolved.  I absolutely could not be happier with my experience with your company and will be proud to recommend you.

 

Please thank Mousa, Julian and Eric again for me
