Our roof has had really ugly mold stains on it for several years. At one point we had honestly considered re-roofing (composite shingles) to get rid of the unsightly stains even though the roof is only 10 years old.
At first we weren't sure what was causing it, but finally after some research became convinced that it could be removed by the proper process.
Finding an Austin-based company that can do this work wasn't easy. The first "Austin" company (according to their website) I contacted finally replied two weeks later to tell me they are based in Michigan and "no longer have an operator in Austin". Then I called another so-called roof cleaning company which turned out to be a young kid trying to make money for college.. not that I'm not supportive of that, but when he came out, it was soon obvious that he had no clue about roof mold or how to remove.
Finally, after much searching, I stumbled on to the (inappropriately named for my purposes) Window Gang.
I called Greg and discussed our issue, he seemed to be knowledgeable about how to remove the mold, and came out the following day for an estimate, (cheaper than the young kid, by the way), and followed up with a firm schedule for the next week.
Sure enough, Dan and David showed up as scheduled with what was clearly a professional setup. They were pleasant, careful, and immediately took to the task. Our roof has a very steep pitch, and quite high off the ground in several areas (No way I'm gonna get up there for any amount of money!)
I had to leave before the job was finished, and went ahead and paid in advance.
When I returned home later that day, I couldn't believe my eyes. Every trace of mold and discoloration was removed from the roof. Now our house looks new again.
I just wish I had the capability of showing a before and after picture. The results are stunning.
I couldn't be more pleased with the Window Gang's work and will certainly be using them in the future. As far as I have been able to find, this is the ONLY legitimate company in the Austin area that will do roof mold removal.
It is a shame that one reviewer gave this company a mere 2 star review, based on insignificant issues (from his own description). That is definitely unjust and does not reflect the professionalism of this company.
Highly recommended! read more
