Timberline HDZ Shingles are easy and fast to install, with an incredible 99.9% nail placement accuracy.

New and modern look
We needed a new roof. I was hesitant about changing the color. However, my salesman guided me through the selection process and we are so happy with the new look. It really gives our house a fresh look
    My home looks beautiful !!!!!
    Our home is the envy of the neighborhood. The roof really sets off our brick home.
      one less thing to worry about
      old roof was 20 years old. was a great relief to have a new quality shingle with quality workmanship
        Much better!
        Our house had a silver metal roof when we purchased it. It was unsound and had to be replaced. We chose a GAF architectural shingle in a weathered wood color. It is much more attractive. And now we have a strong warranty to back it up.
          Changed my homes appearance!
          Quality product from the peel and stick base to the quality shingles.
            Perfect Shingles, Looks Beautiful
            Despite the awful situation with the company and their employees, the actual Roof looks wonderful and we could not be more pleased.
              My home looks fantastic
              Shingles look fantastic with many compliments from my neighbors and the shingles have a lifetime warranty.
                Love the look on our home and outbuildings.
                Great looking shingles making our buildings and home look amazing.
                  The cabin looks beautiful!
                  Only time will tell how the shingles hold up but I am very happy with the way they look.
                    What a difference! My new roof is stunning.
                    My neighbors have all commented on how much better it looks. I couldn't be happier with the service or the product. The GAF shingle's quality is outstanding. What a difference it makes. I'm thrilled with my new roof.
