Client called us asking to repair a leak they had found in their closet. The leak was located about 3 feet from the outer wall. Upon inspection of the roof. We found that the EPDM had pulled away from the the drip edge and entered the home . The Roof also had some pooling in different areas. Owner decided to replace the EPDM roof and not worry about continued leaks. This was the second in the matter of a few months.
Upon removing EPDM roofing we found some weak and rotten Framing underneath, that was designed to shed water from roof. We had to be rebuilt and replace all the now weak framing, So the new roof would last. We reconstructed the hip style roof framing of the roof and install fan fold sub decking and 60 mill TPO with 50 year warranty on a residential application mechanically fastened hat welded seams. Over the entire roof ensuring drainage and no pooling of water on roof.
