Ilia did an excellent job replacing my flat roof - he removed all the previous layers, and did repairs on the roof which, if they were ignored or covered up without being dealt with, would have caused me alot of problems down the road. I feel confident that the work was done correctly. He took pictures to show the work that was being done. Ilia and his team work hard to complete the job and clean up completely. I would not hesitate to recommend him for any roofing job.
