Rated 4.8 out of 5 by 40 reviewers.
Rated 5.0 out of 5.0 by Durable, Reliable for PROS In the past, we would go through 2 roofing guns per year for our roofing crew. We used mostly Bostitch in the past. When their guns got lighter, they got cheaper. I got tired of retiring them after a couple months of use. We would have them repaired. Again, they would lose a spring, a pin or o ring, leaving them inoperable. GARBAGE! I purchased 3 Hitachi Roofing guns. All 3 work well with no problems. Two of the three are 2 and 3 years old. They are used 3x/week for 40+ weeks a year. June 10, 2014

Rated 5.0 out of 5.0 by Excellent Tool! I'll start by saying I don't do this for a living. I bought this gun because it received the best reviews on the HD website. I used this gun to place an asphalt roof on my 12x16 shed and it worked flawlessly...I could have bought a less expensive gun but when it comes to tools, you get what you pay for. I was able to bounce and single nail with this gun. Never jammed once. Now that I have tested the waters with this gun I might try and save myself many thousands of $ by replacing the roof on my house myself. A fantastic nail gun. November 22, 2014
Rated 5.0 out of 5.0 by This is a great tool. . It is well engineered and well made. It served my purpose perfectly February 22, 2015
Rated 4.0 out of 5.0 by Good product The roofing nailer was as described. It worked well, was simple to operate and understand. Saved me many hours on the shingling of my roof. December 15, 2014
Rated 5.0 out of 5.0 by best of the best This is the best roofing nailer on the planet. Over 3200 roofs completed with these guns in the past 4 years, need i say more? November 22, 2011
Rated 2.0 out of 5.0 by Too many double-fires. Not for the newbie or novice who can't (or doesn't want to) bounce nail and needs to single nail instead. Apparently there is a technique for single shooting nails that doesn't require you fit the optional single-shot trigger, but I just couldn't take the time to master it - I had a roof that actually needed to be shingled. So I bought the Porter Cable gun instead and set the Hitachi aside. Yes, the Hitachi feels like it's built better, but the Porter Cable has a selectable trigger right out of the box - it's not a $75 option that you can only get by mail. In my opinion, if you need a single shot trigger it should preferably a) be right there in the box with the gun or b) be available as a no-cost or low-cost accessory. October 7, 2014
Rated 5.0 out of 5.0 by Hitachi is the one to buy I bought this Hitachi nailer to do my roof after wasting time on two Harbor Freight units that jammed all the time. This is a professional level tool and works great. Great unit, works well, what more can I say. July 9, 2011
