Stone-coated steel roofing was conceived during World War II when tar and sand were used to cover galvanized steel bunkers. After the war, the practice was commercialized and the first roofs were produced. Stone coated steel roofs have been protecting buildings for close to 50 years, but the product technology today bears little resemblance to early practices due to advances in the chemistry of coatings.
No. A properly vented steel roof moves air both between the shingles and the underlying deck as well as moving air from vents under the decking. Heated air is allowed to dissipate through the ridgeline as cooler is drawn through eave vents. Reduced energy bills can result from airflow both under and over the decking.
Yes. Some care must be exercised while walking on the roof, but note that roofers walk all over the shingles during the installation process.
TACTILE system will be quiet. The combination of dead air space and the stone coating minimize outside sounds.
TACTILE roofing panels will be able to resist wind speeds in excess of 120-mph.
The steel substrate is protected from corrosion by layers of metallic and polymer coatings. TACTILE will utilize an advanced metal composite developed by BIEC International and introduced in 1973 as aluminium-zinc coated steel. The composite improved earlier metallic coatings by applying an aluminium-zinc alloy to the steel in a continuous hot dip process. The aluminium creates an inert barrier coat while enhancing the long-term performance of zinc and its ability to protect breaks in the coating.
Galvalume coated steel has repeatedly been shown in industry studies, conducted over the last 20 years, to outperform the corrosion resistance of other coated metals.
TACTILE will be using natural stones/ basalt granules, they are not the dyed chips and as a result the colour will remain for many years to come. Over time, a slight change in colour may occur due to settling of airborne contaminants; however periodic rain or washing the roof with a garden hose will keep the roof looking new.
Steel roofing is classified as a non-combustible roofing material (Class A). In new construction and in many re-roofing applications a metal roof is a Class A non-combustible roof assembly. In roof-over applications, where TACTILE panels are installed over old combustible shakes or shingles, the resulting roof assembly can be classified as A, B, or C depending upon the type of underlayment installed between the old and new roof.
A few days based on the complexity of the building.
