"I just completed re-roofing nearly 60,000 SF of 55-year-old roof on the 6th floor of the building here at the Tri-Main Center in Buffalo. I told the roofer at the onsite that I wanted Marathon replacement drains when we first walked the roof. That’s exactly what I got, The “Aluminator” replacement drain! Carmody Roofing went to their supplier, Beacon Building Products to get the dozen or so Marathon replacement drains I needed. I have to say that they add a great finishing touch to the new black EPDM roof. Kudos to the Marathon crew for providing the myriad of roof drain solutions and products for roofing needs everywhere!"
