This profile was designed in-house by Rare and is intended to simulate the look of old world slate. It is made using the same base metal as our other roofing products. It is an interlocking, hidden fastener system, just like our Ironwood Shake. The hip/ridge cap on this profile is also interlocking and each cap covers the fasteners on the previously installed cap.
Minimum slope requirements are 3 in 12. This profile is installed directly onto either a solid sheeted deck or partially filled in skip sheathing. It can be installed directly over asphalt as well, depending on local building codes. The IronStone Slate product is available in a variety of colour choices as shown below.
