Removing 3 Layers Of Asphalt Shingles And Deck Sheathing At One Time?


I'm doing a simple 200 sq. ft replacement and the roof sheathing is going to.

I want to use a circular saw to cut through everything and remove it in small sections.

Can i use a circular saw? I think i did it before but it was over ten years ago the last time i did a small roof project.

I have a beat up circ saw and old blades just wondering is it dangerous?

3 layers of shingles.


I'm a sparky but work is work right now for me. And i'm sure I'll get laughed at by the pros here it's all good

Just wear safety glasses at the least.
Something that small would strip quick enough with a regular stripping shovel though.

I would at least let ithem get warm and rip off the top layer. It should come off easy as long as the shingles aren;t old and crispy

Come to think of it I can use just about anything to pry up the old shingles because I don't have to worry about the nails not coming out...all the sheathing is going anyway.

I have a spade shovel I'll use that saw

thanks guys

About thirty seconds after you start cutting in two things are going to happen.

Your blade housing will be jammed full of gooey asphalt and the teeth will be bent and broken from hitting all the nails.

There are good reasons why tearoffs haven't changed much in 100 years. Just sayin.

BTW, check Home Depot. They have decent wood-handled spuds for around $25

Even if you strip it first (I would), skip the circular saw and put a demo blade on your recip saw.

One of those heavy duty garden forks is all that we used for years.

Good Luck
Dave

We just did this on a big remodel a few months back. It had 2 layers and it came right off with 2 saw blades. No gumming, but yes on hitting nails. Probably 5 sq's

Wear goggles and ear protection.

We went between the bays and 4' sections. Dumpster or trailer. Took 2 of us 3 hours max.

We have used an old skilsaw and blades on 3 layer tears, but that was when we had to keep chit from falling, public job, but we like forks, shovels, and even a leaf spring with a handle and go nuts..

Do you have a forklift? If you do, stab the forks between the rafters rip out and you will done in a half hour.

Couldnt imagine running a saw to tear off. Used pitch forks in the early days and with every 3 layer I think I encounterd the original layer was like crumbs.

Hated doing them not for the rip but the clean up, little pieces
2 sq should talk 20 min to get off.

OMG. Would everyone please just make sure you have video running when you try all these ideas. Post them on youtube and MAKE SURE TO GIVE US THE LINK!

Me? I'd be partial to well-placed explosives. What is funny is many of my contracts specifically forbid me from using explosives for roof demolition.

Re: Removing 3 Layers Of Asphalt Shingles And Deck Sheathing At One Time?


Tomorrow should be my last day on this job!! NEVER again will i do a roofing job.

Anyway the old roof had 4 layers of shingles on it!


Tomorrow I am installing the shingles (another nightmare i bet) but I have a question....

I have to tie into old shingles and they are 4 layers might be 3 not sure...

Will transitioning from 3 layers into 1 layer cause leaking? The new part I'm doing will sit lower now like a half inch.

I should have used 3/4 ply to make the new shingles line up better too late now!

I got in way over my head with this one I know.
