    FAQ’S

    Is a SGB Roofing System more expensive?

    A SGB roof offers more value for your money. With a minimum 50 year life expectancy, you would have to purchase and install 2-1/2 shingle roofs for the cost of one SGB roof. Like most products you buy, "you get what you pay for." A SGB roof offers more for your money. Itís no bargain to put two roofs on your house because the first one was "cheaper

    Why is SGB the "original stone coated steel roofing product"?

    SGB has a long history and is the original stone coated steel product developed by L.J. Fisher in 1957.

    Is a metal roof only for commercial buildings?

    No, SGB's product profiles and attractive ceramic stone granules do not resemble the standing seam roofs of the commercial industry; they add value and curb appeal to any roofing installation.

    Does granule size matter in the longevity of the product?

    Deterioration of the coating takes place when there is exposed, uncovered basecoat; granule size- smaller or larger- does not ensure better coverage.

    Do you use a non-oiled granule?

    We use only 3M granules and they do have a small amount of mineral oil on them. However, the miniscule amount does not interfere with the adhesion of our basecoat, and does not affect water run-off.

    Is water run-off from a metal roof potable?

    Yes, the water run-off from our products meets the World Health Organization Standards testing. However, rainwater is variable across regions; atmospheric conditions should be considered in actual use. Water collected during the first or second rain fall after extended dry periods can be contaminated by dirt accumulation.

    What is the best reason to buy a SGB Roofing System?

    Well, we've given quite a few reasons, but the best reason is our success in the industry. As the original stone coated steel manufacturer, our products have been proven around the world in more than 120 countries since 1957. (link to Roofing Contractor Magazine article)

    Is a SGB Roofing System warranted?

    The best in the industry. SGB Roofing Systems carry a Limited Lifetime Warranty including 120 mph winds, hail penetration for any size hail and manufacturing defects - including excessive granule loss. In addition, material and labor are covered for the first 20 years after that time, material is covered the remaining warranty period.
