Modified bitumen systems combine traditional asphalt with polymer modifiers, enhancing flexibility and performance. Installed in multiple plies, these roofs resist punctures and tearing and withstand heavy foot traffic, cold, and heat.
Metal Commercial Roofing
A prominent choice for sloped or industrial roofs, metal brings unmatched longevity and minimal upkeep. Key variants include steel, aluminum, and copper panels. Metal roofs deliver fire resistance, energy savings, and contemporary aesthetics.
- Standing Seam Metal Roofs: Interlocking panels minimize leaks and shed precipitation efficiently.
- Corrugated Metal Panels: Offer cost-effectiveness for warehouses and agricultural structures.
Green Roofs And Vegetated Roofing Systems
Green or living roofs feature vegetation atop engineered drainage and waterproofing layers. These innovative solutions reduce heat absorption, filter rainwater, and improve building energy efficiency. They are increasingly popular in cities seeking to address stormwater runoff and environmental regulations.
Spray Polyurethane Foam (SPF) Roofing
SPF is a seamless, spray-applied roofing solution that conforms to any roof shape for a watertight and insulated surface. SPF boasts strong energy efficiency and a solid wind uplift rating, suitable for retrofits and complex roof designs.
Asphalt Shingles In Commercial Applications
While primarily residential, asphalt shingles find use on small commercial buildings with steep slopes. Recent innovations have improved shingle durability and resistance to algae, UV, and wind, expanding their applicability for standalone shops or restaurants.
