A gas torch is a vital tool in laying a proper felt roof. Properly applied, the torch allows the roof to be completely sealed, making for a cost effective and durable roof. It’s a skilled process, and involves playing with a lot of heat. We strongly recommend hiring a professional rather than doing this yourself – if you make a mistake the risk of hurting yourself or severely damaging your property are extremely high.

Propane for Roofing

Choosing a torch for roofing

The most common choice of gas for roofing is propane – it’s widely available and relatively cheap.
Torch-on felt needs a wide column of flame, so the torch should be fitted with a large burner – most torches sold for roofing come with a 50mm bell.

Roofing torches are usually fitted with a long enough neck to allow the user to stand up straight whilst applying flame to the roof. Anyone bending over while working will quickly find themselves developing a crick in their back – even if the roof they’re working on is a very small one.

Small propane bottles that connect directly to the torch are not suitable for laying torch-down roofing. Aside from being heavy and unwieldy, they don’t hold much fuel and will need to be changed often. Larger propane bottles connected by a hose are a better choice. The hose should be long enough that the user can complete the layout of a single strip without pausing to move the bottle.

Outfitted with a flow valve and turbo-blast trigger, the propane torch with push button igniter kit is all you need to burn weeds and stumps, soften asphalt and melt ice. The torch kit is designed for easy hook up to a standard size propane tank.
