All Pro Roofing successfully installed a new covering on my 19' x 17' flat roof even in +1C temps. The roof was in dire need of repair, covered in green moss and was the old tar & stone application. They removed 90%+ of the stone, all of the moss, and cleared all the small debris with a leaf blower. In addition they removed adjoining shingles where the flat roof was connected to the remaining house, sufficient to join the two roofs together with the new Duro-Last roofing system. I have every confidence that this investment will outlast any other application and their attention to detail was comforting knowing the job was done by trained workers who took the extra effort & time while installing the Duro-Last roofing system. Money well spent! See my Before and After photos during the Nov 2017 job.
