Is a Torch On (Torch Down) Roof Right for You?

Torch On Roofing

Torch 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.

Gutter repairs

Gutters are commonly found in two formats. Hidden gutters and exposed gutters. Hidden gutters are usually waterproofed using a single ply EPDM membrane. Exposed gutters are aluminum troughs hanging on the face of your fascia boards. I’ve recently done two full repair jobs to rubber gutters. The original installation is never done according to today’s accepted standards. Either the builders didn’t want an expensive system or the chosen roofer was uneducated in Carlisle or Firestone membrane procedures. I find most hidden gutters are leaking at the corners and where the drains are located. It is not necessary to replace the entire gutter membrane because of a leak or several leaks. Although the problem is systemic, it can be fixed by installing patches to all seams and corners. The patches are applied using compatible products. The membrane must first be dried, cleaned and primed. A special uncured membrane patch must be prepared and also primed. The patch is laid in, rolled with a steel roller and then finished with a compatible caulking.
