Roof Cost Calculator for Harrisburg, PA
Get a rough price range for a new shingle or metal roof on a house in Harrisburg, PA, without handing over any contact details. Answer four questions about your home, and the calculator applies 2026 Pennsylvania cost figures to an estimate of your roof's surface. It suits homes across Dauphin County and the nearby townships.
What to Enter
Before you start. The calculator never sees your roof, so it works from your home instead. It takes your living space, divides it by the number of stories to estimate the footprint, then multiplies by a slope factor (1.12 for a walkable roof, 1.30 for a steep one) and by 1.10 for the overhangs. That roof area is then priced at a low and a high rate per square foot.
The rates come from RoofObservations' 2026 Pennsylvania guide. Shingles run from the "Pennsylvania 3-tab shingles, per sq ft" row to the "Pennsylvania premium shingles, per sq ft" row. Metal runs from the "Pennsylvania exposed-fastener metal, per sq ft" row to the "Pennsylvania standing-seam metal, per sq ft" row. All five rows are below.
| Cost row | Figure | Source (year) |
|---|---|---|
| Pennsylvania 3-tab shingles, per sq ft | about $6.45 | RoofObservations, 2026 |
| Pennsylvania architectural shingles, per sq ft | about $7.10 | RoofObservations, 2026 |
| Pennsylvania premium shingles, per sq ft | about $8.80 | RoofObservations, 2026 |
| Pennsylvania exposed-fastener metal, per sq ft | about $9.50 | RoofObservations, 2026 |
| Pennsylvania standing-seam metal, per sq ft | about $14.65 | RoofObservations, 2026 |
The tool covers pitched roofs only. Slate, tile, and flat or low-slope roofs, like the rear sections on many brick rowhouses and twins, each need a roofer's own quote, because their prices fall outside these rows.
After the Result
A range helps with budgeting, and the next step is a price for the roof you actually have. Send a request through the form and it goes to one independent local roofer, who measures the roof, looks at the decking and puts a figure in writing. The referral is free to you; the roofer pays this site for it.
Not sure the roof needs replacing at all? The repair-or-replace checker asks five quick questions about age, wear and storms. The cost guide explains what moves a price, and the Pennsylvania roofing rules page covers contracts and deposits.
