Stone Coated Steel Roofing Tiles

By Richard Maas

Stone coated steel roofing tiles were born from World War II camouflage techniques, using bitumen coated steel with crushed rock applied on top, to hide aircraft hangers. The longevity of those surfaces gave the inspiration to make these products for homeowners.

The result of updating the concept is a striking array of colors, shapes and finishes from a wide variety of manufacturers. These "tile" products are available also as shingle  and shake designs as well as in variations on the tile designs also. The industry standard warranty is for 50 years and to endure 120 mile-per-hour wind. They are fire resistant and have a reputation for resisting hail damage.

Installation of these roofs require some specialized tools and techniques, such as benders and stand mounted cutters. It is important to use nails or screws that are corrosion resistant to the manufacturers specifications. Associated fascia panels, drip edges, flashing, vent fittings, stack coverings,  valleys and related parts are available from the manufactures and are recommended.  Commercial installers should have taken the manufacturers installation course or have certification as well as references.

For all of the high quality of stone coated steel tiles, here are some economic reasons for using them. In the U.S. some of the products in colors that reflect most of the sunlight are eligible for Energy Star tax credits. You can take a credit on your taxes for 10% of the cost (not including installation) up to a maximum of $500, for all improvements combined. Additionally, some insurance companies give a discount for stone coated steel roofing tiles.

It is important to observe the manufacturers recommendations concerning walking on the tiles as some damage may occur. Washing may be necessary to maintain a uniform appearance and specifications should be referred to for pressure washer pressure limits.
