Cheapest Option for Flat Roof: Roll roofing is often the cheapest option for flat roofs, but its lifespan is shorter than other materials.

Affordable Flat Roof Options

1. Built-up roofing (BUR) –  Also known as tar and gravel roofing, is a traditional and cost-effective option for flat roofs. It consists of multiple layers of asphalt-impregnated felt or fiberglass reinforced with layers of hot-applied asphalt or coal tar.
2. Modified Bitumen Roofing – a type of asphalt roofing membrane that is reinforced with polyester or fiberglass. It is commonly installed in rolls and adhered to the roof substrate with heat or adhesives. Modified bitumen roofing offers good durability and weather resistance at a relatively low cost.
3. EPDM (Ethylene Propylene Diene Monomer) Rubber Roofing – EPDM roofing is a durable, lightweight synthetic rubber membrane commonly used for flat roofs. It is attached to the roof with adhesive or fasteners and is relatively inexpensive compared to other materials.
4. PVC (Polyvinyl Chloride) Roofing – Another popular option for flat roofs. They are durable, flexible, and resistant to UV radiation and weathering. PVC roofing is typically installed in rolls and welded together at the seams to create a watertight seal. While PVC roofing may be slightly more expensive than some other flat roofing options, it offers excellent long-term value and performance.
5. TPO (Thermoplastic Polyolefin) Roofing – TPO roofing membranes are known for their affordability and energy efficiency. They are lightweight, durable, and resistant to UV radiation and weathering. TPO roofing is typically installed in rolls and welded together at seams to create a seamless, watertight barrier.
