Roof Replacement Cost in Pennsylvania (2026 Guide)
A new roof is one of the biggest projects a Pennsylvania homeowner takes on. Prices vary a lot from Philadelphia to Pittsburgh, so the best way to know your number is to compare a few local quotes. This guide gives you realistic ranges so you know what to expect.
Typical price ranges
Most roofers price a replacement per "square" (100 sq ft of roof). As a rough 2026 guide for a typical single-family home:
- Shingle (asphalt): the most common choice; for an average home many owners land roughly between $10,000 and $20,000.
- Metal: usually around 2 to 3 times the cost of shingle, but it can last 40+ years.
- Flat roofs (rubber/EPDM, TPO): common on additions and row homes; priced by membrane type and the condition of the deck.
- Slate: the premium option you see on many older Pennsylvania homes; repairs are often smarter than full replacement.
These are ballpark figures, not quotes. Your price depends on the details below.
What changes the price
- Roof size and pitch: steeper roofs need more safety equipment and labor.
- Tear-off: removing one or two old layers adds cost; Pennsylvania code limits how many layers you can have.
- Decking repairs: soft or rotted wood found during tear-off is extra.
- Details: chimneys, skylights, valleys and new flashing all add labor.
- Season: spring and fall are busiest; booking early helps.
Permits and contractor registration
Many Pennsylvania municipalities require a permit for a full replacement. Home improvement contractors in Pennsylvania must also be registered with the Attorney General's office under the Home Improvement Consumer Protection Act; ask for the registration number and check it before you sign.
How to get a fair price
- Get 2 to 3 written quotes for the same scope of work.
- Make sure each quote lists the material, the tear-off, underlayment, flashing and cleanup.
- Ask about the manufacturer warranty and the roofer's own workmanship warranty.
