Ice dams form when heat escaping through your Rosslyn Farms 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 Allegheny County inspection.

Both are single-ply membrane systems used on low-slope roofs. EPDM (rubber) is a single-ply membrane typically installed adhered or ballasted. TPO is a thermoplastic membrane with heat-welded seams that offer strong seam strength. Each has cost and performance trade-offs by application.

Cool roofing products have high solar reflectance and thermal emittance ratings that reduce heat absorption and attic temperature. Energy Star-rated shingles, reflective metal coatings, and white TPO membranes are common examples.

Synthetic slate and shake products offer the appearance of natural materials with better impact resistance, lower weight, and significantly longer service life. They cost more than asphalt but less than genuine slate or wood shake, and are growing in market acceptance.

Class 4 impact-resistant asphalt shingles or standing seam metal are the most appropriate choices in high-hail-frequency areas. Impact ratings should be verified for the specific product — not all products marketed as impact resistant are Class 4 rated.

Hip roofs with metal roofing or high-wind-rated architectural shingles perform best in hurricane environments. Product wind ratings should meet or exceed local building code requirements. Standing seam metal with concealed fasteners offers the strongest wind resistance.

Modified bitumen is an asphalt-based flat roof membrane reinforced with fiberglass or polyester. It's applied in two layers and can be torch-applied, cold-applied, or self-adhered. It's common on low-slope residential and light commercial applications.

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.
