Frequently Asked Questions

What is a "square" in roofing?
A square equals 100 square feet of roof surface. In addition, pittsburgh roofers measure and price by the square, so a 25-square roof means 2,500 sq ft of coverage in shingles, underlayment, and labor.
What's the difference between 3-tab and architectural shingles?
3-tab shingles are flat, single-layer, and typically wind-rated to about 60 mph. As a result, architectural (dimensional) shingles are multi-layer and rated 110–130 mph — the standard choice on most Pittsburgh homes today.
What is "underlayment" and why does Pittsburgh need it?
Underlayment is the water-resistant layer installed between the roof deck and the shingles. For example, in Pittsburgh's freeze-thaw climate, synthetic underlayment plus ice-and-water shield at eaves and valleys is standard protection against ice dams.
What does "ice and water shield" do?
It's a self-adhered waterproof membrane installed along eaves, valleys, and roof penetrations. In fact, building code in most Pittsburgh jurisdictions requires it 24 inches inside the exterior wall line — critical for snow-load winters.
What's "flashing" on a roof?
Flashing is thin metal — typically aluminum or galvanized steel — installed at joints and transitions like chimneys, skylights, valleys, and wall-to-roof intersections. Similarly, failing flashing is the leading source of interior leaks in older Pittsburgh homes.

More Questions Homeowners Ask

What does ACV vs. RCV mean on a roof insurance claim?
ACV (Actual Cash Value) is the depreciated payout your insurer issues upfront. Because of this, rCV (Replacement Cost Value) is the full replacement cost, released once the work is complete and paid invoices are submitted.
What is "roof pitch" or "slope"?
Pitch is the vertical rise over 12 inches of horizontal run — written as 6:12, 9:12, and so on. What’s more, steeper pitches take longer and cost more, and often require added safety gear on Pittsburgh's older two- and three-story homes.
What is a "ridge vent" and do I need one?
A ridge vent runs along the roof peak and lets hot attic air escape. In particular, paired with soffit intake vents, it prevents ice dams and premature shingle failure — critical for Pittsburgh's humid summers and snowy winters.
What does "tear-off" vs. "overlay" mean?
Tear-off strips existing shingles down to the deck before new shingles go on. In addition, overlay adds a second layer on top. As a result, pennsylvania building code allows two layers total, and most Pittsburgh insurers require full tear-off for warranty coverage.
What is a "drip edge"?
An L-shaped metal strip installed along the roof's edges to direct water into the gutter and away from the fascia. For example, it's code-required on asphalt shingle roofs in Pennsylvania and takes about 10 minutes per side to install.
