Lancaster County roof replacement,
priced from space
in 60 seconds.

It depends on your roof, not on a county average, so we do not publish a range. Enter your address on this page and you will see the exact installed price for your home in 60 seconds, measured from satellite imagery, for a complete GAF Timberline HDZ roof system with EPDM rubber membrane on any low-slope sections. No name, phone number or email is required to see it. Online cost guides for Lancaster disagree with each other because they average other people’s roofs; the instant quote here prices yours.

It is the installed price for your roof as measured from satellite imagery, and it is checked twice more before any work starts: first with an independent aerial measurement report, then with an on-site survey. If the survey finds something the imagery could not show, you will know before anything is removed from your roof, and your $500 deposit is refundable until the survey confirms the job. If satellite coverage of your home is poor, you can enter your own measurements and get the same pricing.

A vetted, licensed and insured local roofing contractor, matched to your job after you get your price. Clavos measures the roof, sets the price and finds the roofer; the roofer does the work. Pennsylvania requires every home improvement contractor to register with the Attorney General’s office and to print that registration number on contracts and estimates, and you can check any roofer at hicsearch.attorneygeneral.gov. There is no in-home sales appointment; the only visit before work starts is the on-site survey.

In most cases yes, and it comes from your municipality, not the county. Lancaster County has 60 municipalities — the City of Lancaster plus 18 boroughs and 41 townships — and each issues its own building permits directly or through a third-party code agency. The City of Lancaster’s residential permit application lists roofing as permitted work and requires the contractor’s PA HIC registration number. Inside the city’s historic district, replacing shingles in kind needs a permit but not HARB review; changing the material, such as slate to asphalt, needs a Certificate of Appropriateness before the permit. Some code agencies serving county townships exempt small repairs under a quarter of the roof area in a year, and a full replacement is well past that line. Your installer pulls the permit where one is required.

GAF Timberline HDZ, and yes. Wind is the county’s main roof threat: the National Weather Service logged 143 thunderstorm wind-damage reports in Lancaster County from 2023 through mid-September 2026, including an EF-1 tornado in Columbia on August 20, 2026 that blew shingles off roofs. Timberline HDZ carries a 130 mph wind rating with LayerLock technology. It is also UL 2218 Class 3 impact-rated for the quarter-size or larger hail reported somewhere in the county in three of the last four years, Class A fire-rated, and covered by StainGuard Plus, a 25-year algae limited warranty, for a climate with about 44 inches of rain a year — plus GAF’s Lifetime Limited warranty. Any area at 2/12 pitch or flatter gets EPDM rubber membrane, and standing-seam metal is available as an optional upgrade on the pitched area.

By pitch, with the right material for each plane. About one in five Lancaster County homes is an attached row home or townhouse, and in Lancaster City it is more than half, so low-slope sections on row homes, porches and additions are common here. The satellite measurement classifies each roof plane: anything steeper than 2/12 is priced with GAF Timberline HDZ shingles, and anything at 2/12 or flatter is priced with EPDM rubber membrane, because Pennsylvania’s residential code does not permit asphalt shingles below a 2:12 slope. Your quote shows the two parts broken out.

Most Lancaster County installs start six to ten weeks after project approval — the point where the on-site survey has confirmed the job — and sooner when weather and the installer’s schedule allow. The independent aerial report and the on-site survey both happen inside that window, so by the time work begins your roof has been measured three ways: from satellite, from the aerial report, and in person.

The deposit is $500, and it is refundable until the on-site survey confirms the job. Separately, Pennsylvania’s Home Improvement Consumer Protection Act gives you the right to cancel any home improvement contract within three business days of signing, no matter where you signed it, and the Pennsylvania Supreme Court has confirmed you can cancel by any means — including a phone call or a text — as long as the contractor actually receives it. Financing is available if you would rather not pay the balance outright.

No. Clavos prices one thing: full residential roof replacement, anywhere in Lancaster County. If you need a leak patched or a few shingles replaced, a repair contractor is the right call, and this page cannot quote it. Farmhouses are homes, so they qualify — which comes up in a county with more than 4,600 working farms. For a barn, outbuilding or commercial roof, email jobs@clavos.io and we will tell you whether we can price it.
