Works great!

Our large 100+ year old roof had 5 layers of asphalt roofing (over an inch thick) and a layer of sheet metal over 3/4” boards. The 3T blade cut through all of it with a DeWalt circular saw. This blade saved hours of labor.

Amazing blade

Came across Bigblue on YouTube while researching removing a tar and gravel roof system. I bought just one big blue to try it out and damn, this thing was able to slice through 2300sq ft of the 70yr old tar and gravel on my house roof. In some places it was about 1/2” thick, yet no problem for Bigblue. Hasn’t lost or even damaged a tooth yet. Can’t recommend this blade enough for this type of demo. 5 stars for sure.
