When installed correctly, torch-on waterproofing can last up to 15 or 20 years, making it a cost-effective roof treatment for commercial businesses and homeowners.
Torch-on waterproofing requires a torch to heat fuse asphalt material directly onto a roof to create a waterproof barrier. It is generally used on flat roofs where rainwater can collect and remain for extended periods, causing damage to the roof structure.Torch-on waterproofing is applied at an even thickness across the entire roof surface.
The material used in torch-on waterproofing is a combination of modified bitumen layers coated with various waterproof resins.
Torch-on Waterproofing installation
If the roof is in good shape, the process can start immediately. If not, old material and sheeting should be removed first.
The roof needs to be boarded with a layer of plywood that is nailed to the roof to secure it. This is the base sheet that is necessary to cover the roof smoothly.
Next, the bitumen layer is rolled out onto the base layer. Then a torch is used to melt the material so it adheres to the base. To get a good seal on metal flashings like around vents and chimneys, the material is applied to these metal surfaces before it is covered with the roofing layer.
The Benifits Of torch-on Waterproofing
Torch-on waterproofing is tear and puncture-resistant, which means it will need fewer repairs over its lifetime.
If you need to make any changes to the roof, modifications of the torch-on waterproofing can be done easily.

There is little odour from the torch-on waterproofing material as it is applied, unlike tar and gravel roof treatments.
If the roof is in decent shape and is still flat, it can immediately be covered with torch-on waterproofing, saving you money.
