Flat Roof Installation – how it’s done

Commercial flat roofing is cost-effective to install in Calgary and can be constructed using a wide variety of materials (see below).

These roofs are relatively easy to maintain and allow for efficient use of space, while any potential problems associated with water run-off and debris accumulation can be countered with regular maintenance and inspections.

Depending on the scope of the project, a new installation will typically take anywhere between two weeks and several months.

For installation, our team of professionals will get the installation done right, and accurately. We make frequent visits to the job site to ensure quality, timely delivery, workmanship, and safety. 

We are highly concerned about our customer’s needs and requirements.

Roof Inspections

To ensure that problems are detected early before they become major issues, arrange regular roof inspections with United Roofing.

We can also provide a quote for a replacement roof if required.

Main types of Flat-Roofing Systems

The name flat roof could be deceiving. Flat roofs are not completely flat and often have a slight slope to allow for water runoff (around a quarter-to-a-half-inch per foot).

The climate plays an important role in your choice of materials for flat roofs but, fortunately, there are still plenty of options available.

At BOSS Complete Renovations, this is not a choice you will have to make alone. 

Our certified project managers, engineers, and consultants will be with you every step of your project to ensure your roof is designed with all environmental factors in mind, to ensure the longevity and safety of your roof.

A generous 50-year warranty is provided on all roofs.

Types of flat roofs

How do you know what type of roofing material will best suit your roof’s needs? While Vinyl shingles are a common option in Calgary Alberta there are an array of options to choose from. Your roofing contractor will be able to advise you on the most appropriate material for your specific roof requirements. However, for your reference, we’ve included a list below of the most common roofing material options.

Built-up roofs (BUR)

Built-up roofs are popular, cost-effective, and easy to maintain their durable nature makes them do well in harsh weather and frequent foot traffic.

They consist of multiple layers of insulation boards, tar, and gravel, which create a tough and durable roof. 

When repairing BUR roofs, stripping away the layers and adding new ones is relatively simple. 

These roofs can last up to 40 years with proper maintenance and regular inspections.

PVC Roof

PVC is another sun-reflective, energy-efficient, and weather-resistant membrane used on flat roofing in Calgary. 

You can expect a life of 30 years or more from your PVC roof, and do have a higher upfront cost.

Modified Bitumen Roof

Modified bitumen roofs use a mineral-coated asphalt-based material, which is available in rolled sheets. 

Typically, they are two-ply systems that are generally lighter and more durable than built-up roofing. 

Modified bitumen is considered very stable even if there is high foot traffic. 

The popularity of these roofs is helped by their lower cost and you can expect a life of at least 20-30 years with good maintenance.

EPDM, TPO, or SBS Membrane Roof

EPDM and TPO, energy-efficient, weather-resistant, sun-reflective membranes that are ideal for flat roofs in Calgary. They are cost-effective, easy to install, and available as single or double-ply versions. The main difference between EPDM and TPO is that EPDM is a synthetic rubber while TPO is made from thermoplastic polyolefin. SBS, which is a type of modified bitumen, can also be used in the membrane form. Remember, that SBS is an oil-based product, and the cost of maintenance can fluctuate with the oil market prices. These roofs are installed using insulated board layers and can last up to 35 or 40 years when installed properly and maintained well.
