Roofing 101: Composition
Composition roofing, usually called asphalt shingles, is the most common roof used on houses. It's lowest in cost and easiest to install. Characteristics:
-- Cellulose or fiberglass mats coated with asphalt and granules
-- Many colors available; lighter colors reduce cooling costs
-- Lightweight with flat profile
-- The heavier the shingle, the longer it will last
-- Algae-resistant granules available for warm, humid climates
-- Cost: Starts at $50 per square (100 square feet), uninstalled
-- Many colors available; lighter colors reduce cooling costs
-- Lightweight with flat profile
-- The heavier the shingle, the longer it will last
-- Algae-resistant granules available for warm, humid climates
-- Cost: Starts at $50 per square (100 square feet), uninstalled
Roofing 101: Laminated
Laminated shingles are thicker and heavier than composition roofing. Multilayer panels produce three-dimensional profiles and shadow lines. Characteristics:
-- Fiberglass mat instead of cellulose core
-- Has a shake-like profile
-- Greater fire and wind resistance than composition
-- High-end products weigh up to 450 pounds per square
-- High-end products last 40 to 50 years
-- Cost: $60-$80 per square, uninstalled, more for premium or architectural product lines
-- Has a shake-like profile
-- Greater fire and wind resistance than composition
-- High-end products weigh up to 450 pounds per square
-- High-end products last 40 to 50 years
-- Cost: $60-$80 per square, uninstalled, more for premium or architectural product lines
Roofing 101: Wood
Wood shingles and shakes are made from cedar, redwood, and southern pine. Some local codes prohibit wood because it's flammable. Characteristics:
-- Wood's natural character blends with the landscape
-- Shingles are flat and machine sawn on both sides
-- Shakes are thick and may be hand split
-- Requires a roof with at least 4:12 slope to shed water
-- Lasts 15 to 25 years; apply preservative and fungicide every two to five years
-- Cost: From $100 per square, uninstalled

-- Lasts 15 to 25 years; apply preservative and fungicide every two to five years
-- Cost: From $100 per square, uninstalled
Roofing 101: Metal
Metal shingles are long lasting, lightweight, and fire-resistant, but they conduct heat and can be noisy. Characteristics:
-- Made of aluminum, steel, or copper
-- Come in standing seam, corrugated, or faux-shake styles
-- Can last 40 to 50 years; color coatings guaranteed against fading for 25 years
-- Aluminum won't rust, but lower grades can dent
-- Cost: Steel and aluminum, $100-$260 per square, uninstalled; copper, $250-$500 per square, uninstalled
-- Come in standing seam, corrugated, or faux-shake styles
-- Can last 40 to 50 years; color coatings guaranteed against fading for 25 years
-- Aluminum won't rust, but lower grades can dent
-- Cost: Steel and aluminum, $100-$260 per square, uninstalled; copper, $250-$500 per square, uninstalled
Roofing 101: Clay Tile
Clay tile is a heavy, durable material that complements mission and Spanish-style architecture. Characteristics:

-- Hundreds of glaze colors available
-- Molded from pulverized clay and water
-- Can weigh 1,000+ pounds per square; usually requires reinforced roof framing
-- Lasts 50 to 100 years; tiles can crack or chip
-- Cost: $250-$500 or more per square, uninstalled
-- Hundreds of glaze colors available
