When i seen this add I had to try it. I was tearing off a flat roof that was around 5 inches thick. I don't know how many layers but i was impressed that blade cut threw it. 5'by5' squares around 1200 sq' and used 1 blade. Once you make the fist cut of around 2 1/2 " the roofing below crumbly. VERY IMPRESSED

I used the 5T to cut through the shingles roof sheathing and the roof rafters to cut off the eave to attach a sunroom. The blade cut great, and made quick work of the job. I cut about 60' of the eave and the blade has not shown any sign of dulling. I was very pleased with this blade.

I'm very satisfied with the 5T blade. It rips right through 2 layers and 1/2" obs plywood. I'm really happy and it saved hours so this the only reason I'm sharing my review. This blade does everything they advertise. I'm just a messenger

Grab any 'demo' blades you have laying around a sharpie, and label them rough framing- because after you use use a big blue you'll know what a true demo blade does. These are my go to from now on.

This is the perfect blade for cutting through roofing. I cut about 100 linear feet of a two layered roof and it never gummed up or slowed the saw down. Highly recommended.

We have been using regular sawblades to cut through roofing materials for our HVAC equipment and curbs, saw this blade and bought one and I’ll tell you it is a Bitchin blade. It cuts through anything so smooth easy and my saw doesn’t get clogged up with debris from the roofing materials.

Worked better than expected. Roofing doesn't gunk up in the saw either. I mean the big cutter is more powerful but this thing is a gem. You can absolutely do a whole roof, if you don't have access to a cutter. Just take it easy on the circ saw. Don't force it...

I first bought the Big Blue 5T and I thought it worked well on the demolition of my tar and gravel roof. But when I thought I needed a 5T replacement I read your website and saw that the 3T would probably work better on Tar & Gravel removal. The 3T has worked better than the 5T. The 3T doesn’t get as clogged with tar as the 5T.

I'm tearing off the whole roof and this blade is one angry beast. Rips through plywood and shingles and never misses a beat. No clogging. No stalling. Rip down hill between the rafters and shingle tabs to avoid nails and cut as fast as you want. Tears through the aluminum drip edge to finish the cut. This tool is an absolute must for this kind of job. I always say that there is a right tool for every job and this is the tool for roof demolition.

The blade worked like a charm. I recommend having two individual electric saws. I tried with my Rigid 8 amp battery and could not get more than 8 feet before my battery quit. My saw was Brushless so not sure if that lead to the problem. After switching to the electric, Black and Decker man it was smooth sailing from their. Or maybe not so, I wanted smaller sections but my friend on the asphalt shingle roof, in 90 plus temp and Florida humidity wow, he wanted nothing more but to get r done. So each section ended up being about 2.5 to 3.5 wide by 8 feet long. WE for about 32 sections. The cutting was really the least time consuming. I went thru all four bladed that I purchased. Roof was 3/4 inch plywood, architectural shingles, paper and nailed down with tabs.

If not for the heat here in South Florida, we could have cut smaller sections and not gone as hard on the saw. That's why I recommend having two saws. When one gets hot, you can swap over. I would post a photo of the job but my phone fell off my car and got run over by another vehicle. Waiting on ne w phone, then off on vacation. So, when return I will try to update the pics of the finished work.

Cuts like butter threw 2 layers of asphalt shingles, 1/2 plywood and 3/4 inch barn board. Lasted the whole day. I needed up buying a 4 pack after I bought the 1 as a trial blade.

Bought the 3 tooth blade. It was amazing Ripped through 3” of tar like it was butter

It does what it says and rips through whatever is in front of it. Using a mag77 saw and trying to cut through roofing and sheeting like I would with a thin kerf blade smoked the brushes on my saw in less than 10 minutes. Chalking this up to user error but you have to go slower than you might think with the huge teeth.

I had a flat roof with bitumen build up and a base layer and the blades tore through it, including nails and drip edge. Without these blades we would have had to have purchased or rented a roof cutter. Instead, this blade with a powerful circular saw ate the roof in record time. Having the blade on a circular saw allowed us to get a precise depth also to avoid the decking below. The blades are beasts and we did over 250 linear feet with the blade and it is still cutting.

Work exactly as advertised!

cut through a 1750 square foot flat roof in 2 foot sections with 3 inches of tar no gravel including wood 3/4 inch and 3 inches of tar in 2 foot by 2 foot sections blade never gummed up with design went right through it will use this blade on every project from here on out blade is awesome

We used these to remove 3/4 decking with snow and ice and a 50 year shingle over that.
Blades performed awesome highly recommend.
The key is to take your time 😎

BigBlue™ 5T Demolition Blade

So far so good. Been using blade to demo existing asphalt based roofing on a school project. Cuts thru many layers. Would recommend to others.

I am not the end user, since I am a reseller, but I can comment on the purchase process. First off, the shipping package was a mess when it got here. It looked like someone was shipping out of their basement, using a letter envelope rather than an actual box. The product was also mis shipped. We ordered 6 of the 3-tooth blades and received 3 of the threes and 3 of the four tooth. Cost and performance are the same, but for this to happen without notice from the shipper caused confusion. These things gave the overall impression of a lack of professionalism. If I get feedback from my customer in field about performance of the blade, I will edit with that information.

The blade that I purchased worked great! It cut threw about 7 layers of roofing material and the plywood with no problem. Awesome product.

Worked great until the switch burned up. Had a random parts fall off during use but made repairs with local hardware parts. Overall though it made the job of tearing up flooring way easier

Seriously good demo blade, cut through multiple layer of shingles, plywood, nails! Also, the thickness of the blade makes an extra wide kerf, so material doesn’t bind up when you want it to fall!!

Cut well for a few passes. Then struggled to cut quickly. It did last for a whole roof. But we used old saw blades for a lot of the cutting that went faster

Amazing blade, cut 65 feet of 5 layer composition roofing with ease.👍👍
