How this number is built
We start from a 2026 national baseline for roof replacement and apply a Pennsylvania cost factor of 1.03, which reflects local labour, permitting and material costs. That puts Pennsylvania 3% above the national average — ranked #36 of 51 from cheapest to most expensive.
That's about $4.89–$6.95 per square foot of roof area including tear-off and permits. Roof size drives the total more than anything else — which is why we measure your actual roof from satellite data rather than guessing from house size.
What moves the price
- Roof square footage and number of planes
- Pitch — steeper roofs cost more to work on
- Material: architectural shingle vs metal vs tile
- Layers to tear off, and any decking repair
