This wide range depends heavily on the roofing material (like TPO, EPDM, or modified bitumen), the size and complexity of the roof, accessibility, and necessary decking repairs.

The cost of a new flat roof varies significantly based on materials, size, and location.

For homeowners seeking the most budget-friendly flat roof solution, modified bitumen is typically the cheapest option. This material consists of asphalt-based sheets reinforced with fiberglass or polyester, offering a durable and waterproof membrane at a lower cost than single-ply membranes like TPO or EPDM. While initial installation is affordable, it is important to consider long-term value. A low upfront cost can sometimes lead to higher maintenance expenses or a shorter lifespan.
