tearing down roof advice Answered

I plan on tearing down my roof with a gas torch cutter, i have included the link to my photo bucket gallery for community advice and input;


how does asphalt and concrete react to a high temp torch cutter? will i be cutting through metal plates as well?

Edit: thanks all great responses, since i shouldn't be cutting huge amounts of concrete just the paste binding the shingles together it should be feasible?


I hired 2 friends once to help me roof my house. While we were tearing off the shingles the loose chunks were in a small pile that hadn't been tossed off the roof yet. One of my friends decided it was a good moment to give a tarzan yell and then he STOOD ON HIS HEAD on top of the shingles! We were on top of my ROOF... and this clown was standing on his head on top of loose shingles! Luckily he didn't fall. But that was the last time i hired "friends" to help me save money doing roof work. Besides that... It was hot nasty work and i didn't save any money anyway. I could have had a professional do it for about the same as it costed me after paying them.

Asphalt shingles or rolls are flammable, therefore using a gas torch cutter is an invitation for disaster. The best way is hiring a few buddies like I have done, rent a dumpster and start ripping every shingle with roofing spades. It may take some time depending of the number of friends and the amount of beer (my friends don't work for nothing). Once you clear the roof, remove every nail and sweep thoroughly, you can start installing the new roof.

Concrete can will spall violently if extreme localised heat is applied to it.

In most jurisdictions around the world it's ILLEGAL to burn a tarred roof, let alone a bad idea. Concrete is extremely immune to the effects of a gas torch. You may need to reconsider a more physical approach (demolition equipment).

I agree totally. With the conc. in contact with the steel, you may not even be able to cut thru the steel. Hire some day laborers and rent some equipment.

Forgot to mention, the abundance of concrete-like materials in the building of various furnaces, kilns, and ovens...
