The Pennsylvania permit process, step by step
Confirm whether your scope is permitted work
In Pennsylvania, structural, electrical, plumbing, mechanical and most exterior envelope work on roof replacement projects triggers a permit. Cosmetic, like-for-like repairs often do not.
Let the licensed contractor pull it
A contractor who asks you to pull an owner-builder permit is shifting liability to you. Whoever pulls the permit is responsible for code compliance.
Budget for fees and plan review
Permit fees are usually a percentage of job valuation plus a flat plan-review fee. On a typical Pennsylvania roof replacement project of $8,925 – $35,700, expect permitting to be a low single-digit percentage of the total.
Schedule inspections before you close things up
Rough-in inspections have to happen before drywall, backfill or roofing covers the work. A missed inspection can mean tearing finished work back out.
Keep the final sign-off
The closed permit and certificate of completion belong in your home file — buyers, appraisers and insurers all ask for them on permitted work.
