A roof membrane is a waterproof layer that is applied to the roof deck to protect your home from water infiltration and environmental damage. It is a vital part of your roofing system, providing an added barrier against rain, snow, hail, and other elements that could potentially damage your home. Roof membranes are designed to create a watertight seal and prevent moisture from penetrating your roof structure, thus safeguarding your home’s interior.
They are typically used as part of a flat roof system.
Roof membranes come in various materials and types, each with its own set of advantages and disadvantages. The choice of roof membrane largely depends on your budget, climate, and specific roofing needs. Here are some common types of roof membranes:
BUR roofs consist of multiple layers of asphalt-saturated felt or fiberglass mat. These layers are bonded together with hot asphalt or adhesive.
BUR roofs are known for their durability and longevity, making them suitable for flat and low-slope roofs.
Single-ply membranes are lightweight and easy to install. Common types include:
TPO and PVC membranes offer excellent UV resistance and energy efficiency. EPDM is known for its flexibility and resistance to extreme temperatures.
Modified bitumen roofing combines the advantages of BUR and single-ply membranes. It consists of layers of bitumen (asphalt) mixed with modifiers, reinforced with a fiberglass or polyester mat.
Modified bitumen roofing is known for its toughness and flexibility.
