Metal Roofing

A box-shaped component that connects scuppers to downspouts, helping control the flow of roof runoff and avoiding unsightly cascades. Waterheads are also called conductor heads or rainheads.

Flexible joints built into a roof system that absorb movement from expansion and contraction. They prevent cracking and leaks at connections between different parts of your roof assembly.

An L-shaped piece of roof edge flashing that helps rainwater flow off the roof and away from the fascia boards. It prevents water from seeping under shingles or other roofing materials, protecting the roof deck from rot.

The process where water moves into tiny gaps or along narrow spaces, often against gravity, because of surface tension. In roofing, it can draw water into seams or cut edges, leading to hidden leaks and damage.

The waterproof layer in a roofing system that protects the building from water intrusion and reflects sunlight, lowering energy costs. It’s usually the top layer of the roofing system and can be made of materials like TPO, PVC, EPDM, or modified bitumen.

A type of white single-ply roofing membrane that’s sealed at the seams using hot air, creating a waterproof layer over the roof. It’s commonly used on flat or low-slope commercial buildings, since these roofs need to most protection from water infiltration.

A black, gray or white rubber roofing membrane known for its long lifespan. It’s commonly used on flat or low-slope buildings and is typically glued down, mechanically fastened or ballasted, not heat-welded.

A high-end type of heat-welded thermoplastic membrane that stands up well to oils and chemicals. It’s ideal for restaurants or industrial buildings for its extra resistance, though it usually costs more.

A durable type of heat-welded thermoplastic membrane that reflects sunlight and helps reduce cooling costs. It’s a cost-effective option for flat roofs but may not perform as well as PVC in harsh environments.

A watertight joint created by joining metal roofing or flashing components together. Soldered joints provide long-lasting, durable seals against water infiltration.

The short wall that extends above the roofline, often around the roof’s edge, to provide safety, block wind, and in some cases help manage water drainage. In roofing, parapet walls are usually capped with coping to keep water from seeping into the wall structure.

A roof drain retrofit designed to fit inside existing piping without major demolition. Retro drains are cost-effective solutions for improving drainage on older roofs.
