BUR Removal.


Any particular tools, (or methodologies), those of you with experience might deem indispensable for the efficient removal of built-up roofing? Advice will be appreciated.

My problem: a 10 foot by 38 foot run of asphalt BUR which, though competently installed forty plus years ago, performs no longer.

The decking is nearly dead-flat; the original builder achieved slope by layering the installation, (or "doming" it), from edge to middle. The mid-point thickness -- 3 or 4 inches, maybe more -- would seem to make for a fair amount of material.

If it is mopped on top of insulation on top of the decking, it will be easier.

If is is solidly primed to a wood decking, then it may take a very very long time.

We use a stand up roof cutter, but that would not be an option for you.

I have used a cut-off saw with a diamond tipped demolition blade to score the BUR down to the decking, but the asphalt build up in the blade guard continualu cloggs up. It woks better if you have a self oiler to keep it from sticking inside the guard.

Also, the splatter wil get thrown violently outward in front of you, so unless the immediate area is quite clear, build a plywood deflector dshield wall in front of where you are cutting if you use this method.

The other option is elbows and a**holes. Keep chopping with a sharp axe, but it is for sure a slow and body shaking experience.

BUR Removal.


We did a 5 sq rip on Thursday and it was 4 plies and gravel mopped directly to the plywood sheeting. Fortunately for us it was around 2 degrees Celsius in the morning and once we had a small area opened up the bottom felt paper came off from the mopped plywood with no grief at all, just over an hour and we were all ripped. I did almost a identical rip last july with a morning temp about 20 degrees celsius and it was a nightmare, If I ever came across that again I would just rip out the sheeting and re sheet .
I know of a guy that used a mechanical scraper on one of these and really messed up the owners ceiling with vibration damage.

A DEMO SAW WOULD BE THE WAY to go ,with a shingle eater to remove the plywood,resheathe,and then put tapered isocyanurate insulation down with screws and plates for a good pitched surface for the new hot tar or single ply roof
