Frequently Asked Questions - Stone Coated Steel Roofing

  • 26 gauge, pre-primed, galvanized steel
  • Coated by poured on acrylic basecoat
  • Embedded with ceramic earth-stone granules
  • Over-coated with a clear acrylic glaze and baked on

Yes. However, caution should be taken to only walk the front edges.  The rib sections should not be walked on.

Stone coated steel roofs weigh only about 1.5 lbs per square foot, which is seven times lighter than most clay or concrete tiles which weigh 6 to15 lbs per square foot. Stone coated metal roofs are even lighter than inexpensive asphalt composition shingles, and they are far more durable than any asphalt shingles.

Due to the interlocking design, insulated dead-air space between the roofing layers, and the earth-stone granule finish, these roofs are very quiet. A stone coated metal roof is often much quieter than an asphalt shingle roof.

Not neceissarily. With Boral steel roofs you may be able to leave your roof on as Boral steel has been tested and approved to be installed directly over your existing roof due to its unique installation method. You should check with your local city however, as each city has different ordinances.

The lifespan is 50+ years which is 2-3 times longer than most traditional asphalt shingles.

Again, due to the insulated "dead-air" space, there is no heat gain. Much like dual-pane windows, the design actually works as an energy-saving barrier.

There is minimal movement with steel roofs due to the fully interlocking profile when affixed to the batten. Also, the rough granule finish and angular design add to restricting movement.

Fear of lightning is not a concern, as the steel roof is grounded through existing pipe vents. In realtity, a metal roof may make a lightning strike less dangerous; similar to the way that you are more protected by staying inside of a metal car during a lightning storm.

Boral steel, formerly Gerard roofs have been used in over 30 countries around the world for more than 55 years. These products have beautifully withstood all weather climates.

Stone coated steel is one of the best possible materials for withstanding the devastating hail storms that impact our area of the country. These products come with the highest UL-listed, Class 4 UL impact rating.  Unlike traditional asphalt shingles, large hail stones do not generally damage the integrity or lifespan of the roof.

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.

They are lighter than all other roofing materials. Also a metal roof actually adds shear strength to your structure.

Stone coated steel roofing has been proven to resist wind speeds in excess of 120 MPH. Even if you don't live in tornado or hurricane country, standing up to wind is very important. High velocity winds caused by firestorms can blow burning embers. High winds will cause most roofing to blow off, or in the case of concrete or clay tile, to rise in the front which allows embers to blow under the roof. Flying embers can not get under a stone coated steel roof.

Discounts are offered by many insurance companies. They all have different policies and it is best to you call them and compare.
