Vancouver torch-on roofingTorch on roofing is similar to tar and gravel, consisting of layers of flexible fibreglass and polyester with bitumen. But unlike tar and gravel, it is applied with a torch instead of a hot mop. You don’t experience the unpleasant odours associated with tar and gravel. Sheets are torched down during installation, using large torches that melt the asphalt at the seems, joining them permanently together. The final result is the vulcanization of a large rubber sheet to a flexible fibreglass base. The process is often referred to as modified bitumen because asphalt is mixed with rubber compounds. Torch down roofing provides added strength and resistance to flat and low sloped roofs. It has an average life expectancy of 20+ years.
Torch on roofing is generally considered a more attractive roof than tar and gravel. Its flexibility makes it a good choice for the climate change and extreme weather conditions of the West Coast. It can shift as required and resists brittleness. Torch on provides excellent waterproofing and it is a fire, wind and hail rated roofing system.
Self adhering modified bitumen sheets are available, making patch repairs both practical and cost effective.
