Ice dams form when heat escaping through your Crabtree roof melts snow near the ridge, and that water refreezes at the cold eaves. The ice forces meltwater under shingles and into your home. Prevention requires proper attic insulation and ventilation — both of which we assess during every Westmoreland County inspection.

Yes. Clay tile is significantly heavier than asphalt — typically 900-1200 pounds per square versus 200-350 for asphalt. Many homes not originally built for tile require structural engineering review before tile installation.

Slate has the longest documented service life of common roofing materials — 75-150+ years with minimal maintenance. Standing seam metal follows at 40-70 years. Both have significantly higher upfront costs than asphalt shingles.

OSB (oriented strand board) and plywood are both common decking materials. Plywood has better moisture resistance and structural consistency. OSB is less expensive and widely used. Both perform adequately under properly installed roofing systems.

Dimensional shingle is another term for architectural or laminate shingle — any product with a multi-layer construction that creates a three-dimensional shadow effect on the roof surface. It's the most common type installed today.

Synthetic underlayment is a polymer-based secondary moisture barrier installed over the deck before shingles. It's lighter, stronger, and more slip-resistant than traditional asphalt felt, with better UV resistance for situations where it's exposed before shingle installation.

In climates with high cooling loads — extended summers, high direct sun exposure — Energy Star-rated shingles can reduce attic temperatures meaningfully and lower HVAC runtime. The payback period depends on your climate, home insulation, and HVAC efficiency.

Mixing shingle brands from different manufacturers on the same roof surface is generally not recommended and may void manufacturer warranties. Within a brand, different product lines should not be mixed unless specifically approved.

Class A is the highest fire resistance rating for roofing materials, indicating the product resists fire spread from external sources. Most asphalt shingles carry a Class A rating. Some wood products require fire-retardant treatment to meet Class A.

Lifetime warranty shingles are typically 30+ year laminate products where the manufacturer offers coverage for the life of the original purchaser's ownership. Coverage for workmanship, wind, and algae is often limited within the overall lifetime coverage.

Self-adhered underlayment (ice and water shield) bonds directly to the deck surface, sealing around fasteners and joints to prevent water infiltration. It's required by code at eaves and valleys in most climates.

Algae-resistant shingles incorporate copper or zinc granules into the surface layer that inhibit Gloeocapsa magma growth. Most major manufacturers offer algae-resistant formulations. They're particularly valuable in humid climates where biological growth is common.

Stone-coated steel shingles combine a steel substrate with a stone granule surface coating to provide the appearance of conventional shingles with the durability of metal. They offer excellent impact, wind, and fire resistance.

Standing seam uses concealed fastener panels with raised seams at the panel joints, providing superior water management and a clean appearance. Corrugated metal uses exposed fasteners through the panel surface, which requires more maintenance but costs less.

Steel roofing is protected from corrosion by galvanized or Galvalume (aluminum-zinc alloy) coatings, then painted with a factory finish. Properly installed and maintained metal roofs resist rust for decades. Bare steel without protective coating would rust.
