Is there a significant Difference between roofing and weeding torches?
The weed burner that I have is more of a cross of the 2 torches and yes my weed burner will work but not as well as the roofing torch.
What are the differences the roofing torch is highly focused compared to the weed burner, the focused heat is helpful at not overheating the edges and starting fires where the weed burner can create the heat but tends to flame more (I hope that makes sense)
Other minor things like the cradle to keep the flame pointed up (yes you could make one) but the focused torch can be a help as I have used it not pointing down but horizontal to help put a fire out it sounds funny and it takes some practice but I don’t think you can do that with a weed burner.
(But for small jobs I would and have used my burner)
