Frequantly Ask Questions

  • Q1How long has Stone-Coated Steel roofing been around?

    Stone coated steel roofing occurred 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 5oyears, but the product technology today bears little resemblance to early practices due to advances in the chemistry of coatings.

  • Q3Can you walk on Roofastic steel roof?

    Yes. Some care must be exercised while walking on the roof, but note that roofers walk all over the roof during the installation process.

  • Q5Will a Roofastic rust?

    The steel substrate is protected from corrosion by layers of metallic and polymer coatings. Stone coated utilizes 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 out perform the corrosion resistance of other coated metals. This is why stone coated roof system is referred to as "The final Roofing System", and is backed up with a 30-50 year limited warranty.

  • Q7How long does it take to install a steel roof?

    Usually only a few days. The complexity of the building's roof scape is the primary factor in determining the time required Complex roofs require more time than basic designs.

  • Q9Are steel roofs more susceptible to lightning strikes?

    Steel roofing is no more susceptible to lighting than other roofing materials.It has been demonstrated that lightning strikes most frequently the highest points of terrain. Where concerns exist, lightning rods can be installed on roofs that are the highest point of point of surrounding terrain.

  • Q2Will a Roofastic stone coated tiles make my Home Hot?

    No. A properly vented steel roof system moves air both between the shingles and the underlying decks well as moving air from vents under the decking. Heated air is allowed to dissipate through the ridge line as cooler air is drawn through eave vents. Reduced energy bills can result from airflow both under and over the decking.

  • Q4How do the granules stay bonded to the steel?

    Specially graded, non-oiled stone chips, are used for all stone coated products. The finely graded, non-oiled stone granules ensure long-term adhesion to the steel substrate and are embedded in a UV resistant acrylic polymer for lasting bond to the steel substrate.

  • Q6Does the colour fade?

    Though sized more precisely, Stone coated uses the same stone granules used by asphalt shingle manufacturers for over 50 years so history demonstrates that fading is not a problem. Over time, a slight change in color 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 top.

  • Q8What is the installed weight of a steel roof in comparison to other products?

  • PRODUCT WGT.PER SQ. (1-Sq.ft)
  • Steel Roofing 125lbs
  • Standard (3tab) Asphalt Shingles 190-215lbs
  • Wood Shake/Shingle* 250-300lbs
