LET'S TALK SLATE ROOFING VIEW IMAGE GALLERY COLOR OPTIONS SPECIFICATIONS FireRock Slate Roofing More than any other material, the roof protects the inside of a home from the elements. In addition to protection, the roof also defines the style of a home. A slate roof is the perfect combination of durability and classic style, and that’s why we offer the best slate roofing materials for the FireRock collection. The Strength of Slate and Attributes Longevity – A slate roof can easily last a century and usually much longer Slate is unaffected by weather extremes Tolerates temperature fluctuations and severe weather events Some slate is Miami-Dade accepted for hurricane zones Slate is very dense and does not absorb water 100% fire proof: exceeds all standards for fire resistance Since slate is stone, it simply doesn’t burn Hail is a major cause of roof damage each year - Slate offers excellent hail resistance In fact, S-1 slate has been tested to withstand class 4 ice balls in simulated severe storm conditions Slate is impervious to mold, mildew and insects Color Options Slate is never artificially colored. Its color is determined naturally by geological conditions at its formation. Just as slate from different regions vary in durability, it will also vary in color. Slate also varies in its color retention. Some slate is very consistent or “non-weathering” while some exhibit new shades of color over time and are known as “semi-weathering”. Shown here are colors found in Vermont quarries. Slate’s natural colors can be mixed in endless combinations to create a particular hue to match a design or environment. There are computer simulations for slate color selection. Depending on the intention of the designer, the positioning of the building to viewpoints, and surrounding geography, the roof can become an important visual element.

Slate Grade Pounds (LBS) per square LBS per sq ft Standard Grade “Selects” 680 - 780 6.8 - 7.8 Rough Texture Grade 800 - 1,000 8.0 — 10.0 Architectural Grade 1,200 - 1,600 12.0 - 16.0 Heavy Grade 1,800 - 2,200 18.0 - 22.0 Estate Grade 2,500 - 3,000 25.0 - 30.0 The density of slate contributes to indoor temperature stabilization. Its density makes it heavier than most other roofing materials, particularly in traditional-style slate roof installations. Therefore the overall roof weight must be considered. APPLICATIONS Thanks to new installation technologies, genuine slate is being used more widely in new construction and renovation / re-roofing projects. These new installation systems use approximately 40% less slate (final weight less than 6 lbs/sqft) — reducing material cost and costs related to structural support. This allows projects that were traditionally limited to utilizing asphalt or cedar shakes the opportunity to take advantage of slate roofing. Slate is also often the material of choice for upscale residences where the aesthetic appeal is also desired. These property owners can also take advantage of the low cost of ownership that is attained through slates’s longevity and enhanced property value. Slate is particularly appropriate for large institutional projects where the aesthetic appeal of slate is desired and the budget exists to take advantage of the low cost of ownership that is attained through longevity and enhanced property value. GRADES OF SLATE (BY THICKNESS, UNIFORMITY, TEXTURE) Standard Grade “Selects” are a very uniform 1/4" thick and have a fine texture. Rough Texture Grade slates exhibit unique natural texture and vary from 1/4" to 3/8" with prominent grain definition. Architectural Grade slates have the same characteristics as rough texture with more dynamic grain and texture with thicknesses from 3/8" to 1/2".Can be installed on a combustible floor using LiteRock installation application Heavy Grade slates are similar in character to architectural grade and offer more overall roof texture with thickness variation from 1/2" to 3/4". Estate Grade slates exhibit the greatest dynamic range in texture and asthetic appeal in a stone roof as well as extended longevity, with all slates at least 3/4" thick.
