torch down

I put 3 tab shingle on low pitch roof and leak, is it ok to torch down over shingle, under the shingle is ice guard, or do I need to tear off shingle?

If you don't know that I don't think you should be torching

I concur.

You should not torch over shingles.
You should not torch directly over ice guard.
You should not use a field torch too torch near walls, rakes, eaves or any penetrations in the roof, use a detail torch for those area's.

You should have a fire extinguisher and fire retardant powders with in hands reach at all the times.
You should be aware of your surroundings at all times making sure there's no smoldering of insulation, underlayment materials or anything else during your work or after you have finished.

Best advice, find a safer route.
Hire a pro or use a different material such as a single ply system.

scll, if you happen to have read other topics here on torchdown, you will notice that none of us think it is a DIY system. I've been doing it for 20 years and still am paranoid and nervous when we start a job. There are numerous details and techniques involved to get it done properly and if you miss even one, you will have an improper installation. On top of that it only takes one wrong move to barbecue the patient.

In this situation we tend to encourage the DIY'ers to check into the self-adhering SBS systems. They are much more DIY friendly. Google Flintlastic SA or GAF Liberty SA.

Either way, yes you should start with bare, clean, dry wood substrate.

I agree

I have seen many buildings burnt to the ground from inexperienced torching. Would not recommend it. I would recomend a peel & stick.
