Flat roofs do not shed water as quickly as sloped roofs, so they depend much more on proper drainage, correct layering, and careful detailing at seams, edges, and penetrations. If water is allowed to sit too long or work into a vulnerable transition, the risk of leaks goes up. At Aucoin Roofing, we approach flat roofing as a complete low-slope system so the roof is built to manage water properly and protect the structure below.
