What a Manassas roof costs

We price Manassas by your ZIP, not by your county

There is no single Prince William County number, so we stopped printing one. Manassas prices off its own ZIP — the drive, the permit office, the age and pitch of the housing stock, and what roofs of your size have actually sold for on your streets. Two homes the same size in the same county land thousands apart, and a page that quotes them the same figure is guessing at one of them.

So we measure first. The inspection is free, the 20+ photo report is yours to keep whether or not you hire us, and the number you get back is a written line-item estimate for your roof in your ZIP — not a range copied off a web page.

What moves it most
Pitch, and how much of the roof a crew can reach from the ground.
What hides until tear-off
Layers to remove, and deck condition under them.
What the estimate must list
Flashing, ventilation to code, gutter and fascia work — by line, not as “etc.”

A roof measured at 24 squares that turns out to have two layers and rotten sheathing is a different job from the one any published range describes — which is exactly why we do not publish one. The only accurate figure is a written line-item estimate after a free measured inspection, and you can compare it against anyone. Book the free Manassas inspection →

How it works in Manassas

From inspection to a roof that's done right

  1. 1
    Free 24-hour inspection & photo report. We document every slope, every penetration and every sign of hail or wind damage on your Manassas roof. The report is yours to keep either way.
  2. 2
    A written line-item estimate. Materials, tear-off, decking, flashing, ventilation, permit and warranty, each on its own line. Not a single number on the back of a card.
  3. 3
    Permit pulled, date scheduled. We pull the Manassas permit and the number goes on your contract. Most single-family roofs install in one day.
  4. 4
    Final walk and warranty registered. Magnet sweep of the property, photos of the finished work, GAF limited lifetime material coverage registered in your name, and our workmanship warranty stated in the contract you signed.

Roofs in Manassas

What we actually find on Manassas roofs

The Manassas postal area covers three separate jurisdictions: the independent City of Manassas at its historic centre, the independent City of Manassas Park beside it, and a large ring of unincorporated Prince William County subdivisions from the 1970s onward.

A Manassas address does not tell you who issues your permit. 20110 is the independent city with its own office; 20109, 20111 and 20112 are unincorporated Prince William County. Prince William publishes the exclusion on its own site -- it does not serve the Cities of Manassas or Manassas Park. Three jurisdictions, one mailing address, and the wrong filing costs a week.

The county-side subdivisions were built in large uniform runs and age the same way -- as a street rather than as a house. If neighbours are re-roofing, that is data about your own roof, not a trend.

The older housing near the historic centre carries board decking and multiple layers, and the historic district adds exterior review to anything visible from the street. Both change the tear-off and both belong in the estimate.

Permits & approvals

Who signs off on a roof in Manassas

Roofing permits for Manassas are handled by Prince William County Building Permitting Services. Their permit line is 703-792-6924. We pull the permit as part of the job — you are not meant to be chasing this — but it is your house, so you should know who is actually deciding.

Worth knowing: SPLIT JURISDICTION. ZIP 20110 is the independent CITY of Manassas with its own permit office; 20109, 20111 and 20112 are unincorporated Prince William County and permit through Building Permitting Services on 703-792-6924. Prince William states the exclusion on its own site: its Department of Development Services does not serve the Cities of Manassas or Manassas Park. Manassas Park is a third, separate independent city. A Manassas mailing address does not settle which of the three you are in. Read from pwcva.gov 2026-09-03.

Permit rules change and depend on the scope of the work — replacing shingles, replacing decking and rebuilding a roof structure are not treated the same. Confirm anything that matters to you with the office above rather than with any contractor's website, including ours.

Manassas roofing questions

Straight answers

Do you serve Manassas, VA?

Yes — United Developers serves all of Manassas and Prince William County, including 20109, 20110, 20111, 20112 and nearby Manassas Park, Bristow, Gainesville. We are GAF Certified and licensed in Virginia (VA Class A #2705183185).

What does a new roof cost in Manassas?

We price Manassas by ZIP rather than publishing one Prince William County figure, because there is no single figure that is true across a county — the drive, the permit office, the age and pitch of the housing stock and what roofs of your size have actually sold for on your streets all move it. The real number comes off a measurement and an inspection: pitch, layers to tear off, deck condition found once the shingles are up, chimney and skylight flashing, and how much of the roof a crew can reach from the ground. The inspection is free and the photo report is yours to keep.

Who pulls the roofing permit in Manassas?

Roof replacement in Manassas is permitted through Prince William County Building Permitting Services (703-792-6924). We pull it, we schedule the inspection, and the permit number is on your contract — you should never be asked to pull your own roofing permit.

Is the Manassas roof inspection really free?

Yes. The inspection and the 20+ photo damage report are free and yours to keep whether or not you hire us. No inspection fee, no consultation invoice, and if your roof does not need work we will tell you that.

Will insurance cover my Manassas roof?

If your roof has storm, hail or wind damage, your policy may cover a replacement — on an approved claim your deductible is typically your out-of-pocket cost. We document the damage, provide a line-item estimate, and meet your adjuster on-site. We are a roofing contractor, not a public adjuster, and we do not negotiate your claim for you.

How fast can you get to my Manassas home?

We typically schedule a free inspection within 24 hours across Prince William County. Calls are answered and appointments booked 24/7; crews work daylight hours. For an active leak call (240) 880-2108 and we will prioritise you.

Has there been storm damage in Prince William County recently?

NOAA logged 29 storm reports in Prince William County in the last 6 months, with hail measured up to 1″. Storm data is preliminary NOAA/NWS public data; damage on your specific roof is confirmed at the inspection, not from a map.
