Built-Up Roofing (BUR)
BUR is one of the most reliable flat roofing systems we offer. It is made by layering multiple sheets of asphalt and reinforcing fabrics.

The surface can be finished with gravel or a reflective coating.

Modified Bitumen Roofing
Modified Bitumen roofing combines asphalt with synthetic rubber or plastic. This mix adds flexibility to the roofing material and improves its resistance to temperature changes and UV rays important in a city where temperatures range from winter lows around 46°F to summer highs of 84°F. We install Modified Bitumen in sheets that are often heat-welded onto the roof deck.

EPDM is a rubber-based material known for its flexibility and resistance to UV light. It's ideal for roofs with curves or irregular shapes and is highly durable against weathering perfect for the diverse architectural styles found throughout Westminster's 10 square miles.
TPO is a plastic-based membrane that is heat-welded at seams for a secure, watertight bond.
