Stone Coated Steel
The following pictures show how we install a stone coated steel roof, either direct to deck (batten less) or with battens. The selection of the installation method is based on a discussion at the time of an estimate.
Within the descriptive photo sequence we have three different applications:
#1: The first sequence is a home that had a Concrete Tile roof. The weight of the concrete was causing the rafters to sway by as much as 4 inches. To remedy the problem we tore off the concrete tile roof, applied a synthetic moisture barrier and then took the sway out of the roof by installing a 1×4 and 2×2 batten system with shims. This process leveled the roof without having to remove rafters inside the structure and then re assembling the plywood. After the battens were installed we then installed the new Metro Shake panels onto the battens. The weight of the Concrete Tile was approximately 10 pounds per square foot and the Steel Roof installed is 2 pounds per square foot.
#2: The second sequence represents tearing off a wood shake roof down to the plywood sheathing. The roof was very steep, so for ease and safety we installed a 2×2 batten system over the synthetic underlayment. Stone Coated Steel panels were then screwed to the 2×2 battens. Finishing the install we replaced all flashings and added more roof ventilation by using dormer vents.
#3: The third sequence represents a more common install of Stone Coated Steel panels. This home had two layers of existing roofing. The first layer was wood shingle and the second was a 20 year old asphalt composition roof. Since the wood shingle roof was not torn off when the asphalt shingle roof was installed, the home did not have full plywood sheathing.
The original wood roof was installed over skip sheathing. Skip sheathing was used when the home’s original roof was a wood shake or wood shingle. Nailing 1×4’s to the rafters with a gap in between the 1×4’s allowed the roof to breathe better than if the home had plywood installed. This benefit of skip sheathing allowed the wood roof to last longer due to less heat load in the attic.
If a home’s roof structure has skip sheathing, then once the wood roof is torn off, we have options to install the Steel panels. In this case we installed, as necessary, new skip sheathing and covered with a synthetic underlayment. We then screwed the Metro Shake Steel panels to the skip sheathing and then replaced all necessary flashing. We also added roof ventilation by installing Dormers to evacuate hot air out of the attic.
Regardless of a home’s existing roof sheathing; either full plywood sheathing or skip sheathing, most Stone Coated Steel panels can be installed with or without battens.
