Commercial and Industrial Flat Roofing Systems

We do not want to promote any certain roofing material over another because the location of your roof and its surrounding environment are key factors in choosing a flat roofing system. Also, your available building finances must be taken into consideration. Some companies choose to invest in a more cost effective roof and then a maintenance program to extend the life of the roof while others choose to spend more on the roof and a more spread out maintenance plan. Call us to discuss which roofing system is right for you.

If you are not sure what type of roof you have, or if you are in need of flat roof replacement or flat roof repair, give us a call. With our years of experience we can repair or replace almost any type of commercial industrial roof. We specialize in:


Modified Bitumen Roof

Modified Bitumen RoofingModified Bitumen (MB) is asphalt that has had modifiers added to it to give it plastic or rubber-like properties. Installed in layers which are either torch welded or adhered using factory applied adhesive Modified Bitumen can be a cost-effective alternative. The longevity and warranty received on the product is dependent on the maintenance, quality of and number of layers installed.

Engineered modified bitumen originated in Europe in the mid 1960's and has become a standard commercial roof application and has been being successfully used in Canada since approximately 1975.

Mineral-surfaced roofing products are typically furnished with granules, but are also available in designer colors to match asphalt shingles or to otherwise compliment the overall building design.

TPO (Thermo-plastic Polyolefin)

TPO Roofing

TPO is typically based on polypropylene and Ethylene-propylene rubber polymerized together using state-of-the-art polymer manufacturing technology. This technology enables the production of TPO membranes that are flexible at low temperatures without the use of polymeric or liquid plasticizers.

It is relatively new in the roofing market but has a high return for its cost. Lightweight, completely waterproof, resistant to punctures and tears and highly flexible (important when considering the temperature fluctuations of winter and summer). TPO also is available in white colour resulting in a highly reflective surface that can save you heating and cooling costs. Some manufacturers of TPO roofing materials also market it as “seamless” due to the hot-air welded seams – a much stronger alternative to adhesives.

Unlike some other popular thermoplastic roofing membranes, the TPO polymer does not contain chlorine and no chlorine-containing ingredients are added during sheet production. This lack of chlorine allows TPO marketers to advertise their membrane as an environmentally safe, “green” product.

EPDM (Ethylene Propylene Diene Monomer)

EPDM RoofingOne of the most popular commercial roofing options is EPDM roofing. EPDM roofing systems are lightweight and simple to install. It is a single-ply membrane like TPO and PVC made of synthetic rubber which has been improved over the years so that current EPDM roofing systems are incredibly durable, tear and highly puncture resistant while maintaining flexibility. EPDM roofs have superior resistance to extreme heat and fire, and ultraviolet radiation.

This type of roofing system is applied using a fully-adhered glue system, loose-laid with gravel or mechanically fastened. None of which require an open flame. The use of adhesive and nails to install results in the environmental benefits being reduced emissions from the amount of equipment needed to install it, there are fewer petroleum based product s and less landfill waste.

Some argue that this type of rflat oofing system is not the most aesthetically pleasing but then that is generally insignificant to a building owner. Alternatively, this type of roof is available in different colours like white grey or black and it can be manufactured in wide rolls to minimize the number of seams.

BUR (Built-Up Roofing)

BUR Flat Roofing>Built-Up Roofing (BUR – "tar and gravel" – coal tar - asphalt and gravel) is the most classic "tar and gravel" system of roofing. Traditionally flat roofs have been installed by setting three - four layers of coal tar with coal tar saturated felts (tar-paper). Typically, the surfacing is gravel set in a flood-coat of hot asphalt. Coal tar is a by-product of the coal manufacturing process and makes an excellent water and oil resistant material.

It is always important to consider your location in the world when choosing a roof because of important factors like ultra violet rays. An asphalt and gravel roof can be adversely affected by ultra violet rays and will not maintain its integrity if water is ponding on top of it because it is moisture resistant rather than moisture proof. Alternatively Coal Tar Built-up roofing has a molecular structure that provides a natural resistance to water, ultraviolet rays and chemicals -things which are commonly found in a rooftop environment.

PVC (Poly Vinyl Chloride)

PVC RoofingPVC (Poly Vinyl Chloride) roofing is another popular choice for commercial applications. Flexible, durable, with little seams or joints and with quick and simple installation. PVC roofing is also chemical resistant making it excellent for applications for restaurants or other sites where grease or chemicals would otherwise eat away the membrane over time. Available in reflective colours as well, PVC Roofing is often times toted as the best roofing material available.

PVC meets all applicable building codes. PVC membranes also meet the cool roofing requirements of EnergyStar®, Green Globes™, and LEED®.

PVC is one of the most durable waterproofing options. It is a product that has proven it can serve its purpose for a longer period of time without need for replacement. This type of roofing also has an established end-of-life recycling program that converts the old membrane back into roofing membrane products.

As with most roofing materials, it is naturally fire retardant and will self extinguish with the removal of the flame source.
