Stone coated steel roofing is approximately 15-20% more expensive than traditional materials initially, but provides overall value savings over time through reduced maintenance and energy costs as it will not need replacing like other roofs. Tefute Building Materials offers lifetime warranties of over 60 years, one of the best in the industry, for their stone coated steel products and services. Stone coated steel roofs typically last 40-70 years when installed properly, much longer than asphalt shingles that need replacing every 20 years, and can withstand harsh weather conditions better than other materials.
