Ryan McBee (Poplar Grove, IL)
BigBlue 3T Blade

I had to cut through a built-up asphalt Flat Roof.
I was a little skeptical at first ordering a blade with only 3 Teeth on the whole blade, but this did the job!!
I had to demo out a good 1 1/2" thick roof, and it cut right through it.
The circular saw gets very dirty though (which is to be expected), so be ready for that.
Love this Blade!!

BigBlue 3T Roofing Demolition Blade.

This blade exceeded my expectations. Cut through cold tar roof, metal gravel stop and underlayment of slate with minimal effort. Blade lasted longer than I expected.
Excellent product.

Great Company

I researched best roof cutting blades and Smartman had it. I needed the blades in less than a week to rip my roof up. They were shipped quickly and arrived a day earlier than expected. They even emailed me to make sure they arrived in time.
Will definitely be doing business with them in the future
