2-Ply Modified Bitumen Roofing

This system consists of two plies of thick polyester reinforced modified bitumen asphalt covered in shingle-style granules, creating a monolithic roof about 3/8" thick. We adhere the layers with adhesives and heat-weld the membrane together, eliminating hot asphalt and smelly kettles. 


The exposed membrane design offers incredible puncture resistance and simple repairs. Designed to last 25+ years, this system allows for cost-saving restoration. When nearing end of life, we can torch another granulated cap sheet over the existing roof, reusing the base system.

Built-Up (BUR) Roofing System

We construct this system from alternate layers of bitumen and strong fabrics with hot asphalt and gravel, available in 3, 4, or 5-ply configurations. The seamless structure withstands harsh climates, heavy foot traffic, and rooftop machinery, making it a popular choice in the Canadian market. 


This inverted or conventional system offers easy repair, low maintenance, strong durability, and UV ray resistance. With professional installation, BUR roofs last over 20 years while handling extreme weather conditions.


EPDM Roofing System

This durable synthetic rubber membrane features reinforced rubber sheets with exceptional mechanical quality and weather resistance. We install EPDM using three methods (fully adhered, mechanically tied, or ballasted) and seal seams with liquid adhesives or specialized tape. 


Available in various thickness levels, EPDM flexes with your structure's movements and resists extreme temperatures, thermal shock, hail, and UV rays. The system is reusable for re-roofing applications, offering long-term value.

 TPO Roofing System

Our single-ply TPO membrane is a lightweight system that delivers high performance at an affordable price point. We hot-air weld all membrane seams to create strong waterproof bonds between sheets. 


This energy-efficient roofing withstands any weather conditions while resisting fungal growth and physical damage. TPO roofs combine durability with cost-effectiveness for businesses seeking quality without premium pricing.


Metal Roofing

We install corrugated galvanized steel coated with zinc, plus aluminum, copper, and stainless-steel options in various colours. Metal roofs excel in rainy and snowy climates with superior resistance to heat, large impacts, and high winds. 


This eco-friendly, energy-efficient system requires low maintenance and offers non-combustible protection. With exceptional lifespan and endurance, metal roofing provides decades of reliable performance.

 Liquid Applied Coatings

We apply protective coatings over asphalt, bitumen, concrete, felt, and other traditional roofing materials to extend your roof’s lifespan. These high-performance coatings shield against physical damage, UV rays, and normal wear while resisting extreme temperatures. 


The reflective properties prevent heat transfer into buildings with cooling systems, lowering energy bills in the summer. This cost-effective solution adds years of service to existing roofs.
