What Are Flat Roofing Systems?
Flat roofs are commonly used in commercial buildings because of their cost-effectiveness, ease of installation, and space-saving benefits. Unlike sloped roofs, flat roofs have a slight slope (¼ inch per foot) for drainage.
Benefits of Flat Roofing Systems:
✔️ Cost-effective installation compared to sloped roofs
✔️ More usable space for HVAC units & solar panels
✔️ Easier access for maintenance & repairs
✔️ Modern, sleek appearance
