Engineered to Protect Your Home, Family and Other Valuables Against the Elements

Our 3-tab roofing shingles are built to last, thanks to their solid construction, flexible fiberglass mat and weather-resistant design. And, because they come in a metric size that’s larger than many comparable shingles in their class, they’re faster and easier to install.

1. An Exceptional Bonding Experience

IKO Fastlock™ sealant strips run across the back of the shingles to help prevent wind-driv­en rain from getting underneath them. When activated by the sun’s heat, the sealant strips get extra-tacky and create a strong bond.

2. Surface Granules for Color and Protection

At IKO, we quarry, crush and color our own ceramic granules then embed them into the weathering asphalt that coats the fiberglass mat top and bottom. These granules help protect against the sun’s ultraviolet rays that could potentially compromise the shingles’ durability and performance.

Did You Know?

Many homeowners choose our traditional 3-tab shingles to replace the roof on other types of out-buildings, from tool sheds and gazebos to dog houses! Easy to install and  economically priced, they’re available in a wide range of attractive color blends.

Count on IKO for a comprehensive line of quality accessory roofing products – ice and water protectors, synthetic underlayments, ridge cap shingles, starter strips, adhesives and more – to support the installation of almost any roofing project.
