Drainage is one of the most important parts of flat roof performance because low-slope roofs do not shed water as quickly as steep roofs. If water is allowed to sit on the surface, it can lead to faster wear, seam stress, and a greater risk of leaks over time. In Hamilton, flat roofs also have to deal with heavy rain, snowmelt, freeze-thaw cycles, and seasonal exposure, which makes proper drainage even more important. Aucoin Roofing evaluates drainage as part of the full roofing system so the roof is built to manage water properly and protect the structure below.
