Roofing & Flashing
From TPO to EPDM to Green roofs, we’ve got the experience and manpower to get it done. All our solutions include flashing fabrication and installation from our metal shop.


We know how important it is to our general contractors and building owners that their roofing projects be competitively priced, well-done, completed on schedule and as specified. Our foremen receive training in scheduling; planning and blueprint reading so that they are better prepared to not only complete the job but to efficiently handle any problems that may occur on site. Additionally, they, along with our roofing crew, receive safety training to ensure that our work sites are safe. Good housekeeping practices result in our job sites being left in an orderly condition upon completion.



When regular maintenance and repair methods have been exhausted, Raven Roofing can advise you on the best replacement roof system and the best method of installation according to your unique needs. It is paramount that our re-roofing projects are completed with the least amount of disruption to building occupants and to this end we maintain open communication with the owners and tenants. Our crews are experienced and knowledgeable when it comes to re-roofs and pay particular attention to the removal of debris without incident.


Roofing Systems

EPDM Roofing
Ethylene Propylene Diene Monome

EPDM is an extremely durable synthetic rubber roofing membrane (ethylene propylene diene monomer) widely used in low-slope buildings. Its two primary ingredients, ethylene and propylene, are derived from oil and natural gas. EPDM is available in both black and white, and is sold in a variety of widths, ranging from 7.5 feet to fifty feet, and in two thicknesses, 45 and 60 mils. EPDM can be installed either fully adhered, mechanically attached or ballasted, with the seams of the roofing system sealed with specially formulated tape.

Thermoplastic Polyolefin

TPO membrane is a single-ply, flexible, and durable roofing solution used for steep or low-slope buildings. The seams are weldable with hot air. The membranes have excellent ozone resistance, are algae-resistant, long-lasting and environmentally sound. A TPO membrane roof is very resistant to tears, punctures and impact damage. The flexibility also allows for building movement and settling. TPO membranes can be installed in two different ways: fully adhered or mechanically attached. The membranes come in white, grey or tan. Custom colours are available as well.

Styrene Butadiene Styrene

Modified bitumen is a roofing asphalt that was designed for use on buildings that have a low slope or flat roof. There are a wide range of methods available for installing modified bitumen roofing, from using a hot torch to using a sealant-backed peel and stick rolls. Modified bitumen roofing has excellent waterproofing features, and the cost of installation is competitive with other materials when you consider the life of the product.

Brickyard Station

A green or living roof is a roof that is partially or completely covered with vegetation planted over a waterproof membrane. Two types of green roof exist: intensive and extensive. Intensive green roofs are essentially elevated parks. They can sustain shrubs, trees, walkways and benches with their complex structural support, irrigation, drainage and root protection layers. Extensive green roofs are relatively light and support hearty native ground cover that requires little maintenance. Extensive green roofs usually exist solely for their environmental benefits and don’t function as accessible rooftop gardens.

Surrey Library

Metal roofing is a preferred alternative for sloped roofs. Various profiles are engineered to accomodate the slope of the roof. They are also designed to provide pleasing aesthetics, since they are typically visible from ground level.


Properly made and installed flashings are necessary to ensure a leak free roof and, aesthetically, they are the “icing” on your new roof. Raven MetaPro, our metal division, custom fabricates and installs all our metal products. Our state of the art equipment and highly trained operators enable us to manufacture your flashings to exact specifications.
