Professional Roofers has been repairing and replacing roofs in Toronto for over two decades. We are your source for all roofing solutions, including SPF flat roof installation (Spray Polyurethane Foam).

Our Toronto roofing company is your source for SPF —  in fact, we are one of the few companies in Ontario that are fully experienced and licensed to install SPF solutions.

The thing is, flat roofs are horizontal — unlike traditional sloped roofs that have inclines that help water run-off.  At one point, tar and gravel were used to help prevent water from penetrating the surface of flat roofs. However, due to harsh weathers, these materials proved to be susceptible to sagging and usually resulted in water pooling.

Flat roofing requires special materials and strategies like SPF to ensure that water can effectively run off. We build our flat roofs on a slight angle to help prevent pooling and provide proper drainage.

SPF is a liquid material that expands into a foam and creates a sustainable, protective layer for your roof. The flat roofing material is known to be efficient, time-effective and durable in extreme weather conditions.

We work with customer satisfaction in mind, which is why we provide SPF services to make sure that your flat roof is durable, water resistant, sustainable, and doesn’t break the bank.

We provide SPF solutions in Toronto, Brampton, Mississauga, Oakville, Burlington, Aurora, Newmarket and all other GTA areas! Be sure to get in touch for our services today.

What Is SPF Roofing?

By definition, Spray Polyurethane Foam (SPF) is a liquid material that, within a matter of seconds, expands into a rigid, closed cell foam. As it dries, it increases by 30 times its size and becomes a watertight, durable blanket that extends across your entire roof.


This is How SPF Works

The foam is heated by a pump to make sure that every component of the spray is proportioned.

The components are mixed at the spray gun before they are applied to the roof.

The protective surfacing is either sprayed or applied by a hand or roller to provide weatherproofing.


SPF is the most cost-effective and sustainable roofing system currently available. It works fast, works well, and lasts for a long time. The system is an effective flat roofing solution for industrial, commercial and residential spaces. The advantages of SPF are endless.

Thanks to its protective layers, SPF is weatherproof and protects your roof from UV rays. The layer helps to fire-proof the material and makes it resistant to machine caused damage.

The Benefits of SPF for Flat Roofing

The advantages of using SPF are endless. The material saves you money by being energy efficient, requiring infrequent repairs, and just by being a long-lasting solution — among other things.

These are the main reasons why SPF is considered to be an effective option when it comes to flat roofing:

spray on roofing Lightweight

Because SPF is so lightweight, it actually puts less pressure on your roof. Don’t worry though — even though it’s lightweight, it is still resistant to external factors. Believe it or not, SPF is the perfect balance — it’s light on your roof, but heavy against damage.


It’s Customizable

Because SPF is a liquid upon application, you can customize it to accommodate for any specific drainage needs your roof may have.

This material can save homeowners up to 50 percent on energy bills and long-term repairs.

Long Lasting

SPF has a life expectancy of 30 + years and requires minimal maintenance. In fact, a flat roof with SPF only needs to be checked twice a year.

SPF adds structural strength that protects your roof in extreme weather conditions not limited to high winds and hurricanes. Because the material is secured with ballasts, strips, or strong fasteners, it is well sealed which allows it to better resist wind and other factors.


Every Building Can Use It

SPF flat roofs, due to their various advantages, are commonly used by a variety of buildings not limited to homes, and both commercial and residential buildings.

Not only is SPF waterproof, but it has a high insulation value that makes it impossible for water to penetrate it. In fact, the foam stays dry even upon contact with water.


Environmentally Friendly

SPF is one of the most eco-conscious roofing solutions.  Not only does it save energy, but more and more SPF materials are being made with renewable resource materials.

According to GreenBuildingSolutions, SPF manages to save homeowners on energy costs because it is applied above the deck of the roof and is usually protected by a coating that is light-coloured and reflective. The foam is such an effective insulation tool that it even manages to help keep down a home’s energy costs.


Weather Conditions

As mentioned, SPF is resistant to extreme weather conditions. In the winter it keeps the wind out, and in the summer, it keeps the heat out thanks to its protective layer that is resilient against strong UV rays.


SPF Roofing Details You Need to Know

Once upon a time — back in the 1960s — SPF was used for industrial and refrigeration insulation. Now, it’s used as an effective roofing application.

SPF is a lesser-known flat roofing solution, despite the fact that it is the most cost-effective and environmentally friendly option available for roofing. These are the main details you are going to want to know about the material:

spray on roofing How Does How it Work

In simple terms, the liquid material is applied to your roof and increases in size by 30 percent to provide a watertight cover. SPF dries as a hard, durable foam that seals your roof. Another protective layer is then applied, which is what makes SPF durable and resistant to harsh weather conditions.


spray on roofing What is SPF Made Out Of?

According to Spray Polyurethane Foam Health & Safety, SPF is formed by combining two liquids; one is a combination of methylene diphenyl diisocyanate (MDI) and polymeric methylene diphenyl diisocyanate (pMDI), and the other is a mixture of catalysts, flame retardant, surfactant and polyols. These two liquids are respectively labelled as “A” and “B” before they are brought together. When combined, they react to one another instantly to expand and create the foam.
