Most Chantilly homeowners don't search for a roof replacement company. They search for a roofing contractor, because the first question is usually whether the roof needs replacing at all. We start in the same place: an inspection of the roof you actually have, followed by a straight answer about repair versus replacement. If replacement is the right call, everything below is part of one coordinated project rather than a series of decisions made after the old roof is already off.
What a full roof replacement includes
- Roof inspection and a material recommendation based on your roof's slopes, valleys and penetrations.
- Tear-off of the existing roof, down to the decking.
- Decking repair where the boards underneath turn out to be damaged.
- Installation of the new roofing system: underlayment, flashing, shingles, ridge and accessory components.
- A ventilation review, so intake and exhaust are considered with the new roof rather than ignored.
- Cleanup and debris removal at the end of the job.
Each of those items should appear in the written scope with enough detail to compare against another roofing company's proposal. If something is an allowance, such as a set amount of replacement decking, the scope should say so and explain how anything beyond that is documented and approved.
The photos above are from a full roof replacement in Centreville, Chantilly's neighbor to the south. We haven't photographed a finished project in Chantilly yet, so we won't show you one and call it local. What carries over is the sequence: harnessed tear-off, underlayment with bundles staged, then finished architectural shingles.
Why the county matters for a Chantilly roof
Chantilly is an unincorporated community in western Fairfax County, so roofing questions go to Fairfax County Land Development Services, not a town hall. The county's own permit guidance lists replacement of roof shingles on a home as work that does not need a building permit, and replacing less than 256 square feet (nine boards) of roof plywood is also on that list, unless the roof is required to be fire rated, which the county gives townhomes as an example of. Larger decking replacement and roof repairs are a different conversation, which is one reason we write down the decking assumption before tear-off.
There is one Chantilly wrinkle worth knowing: some homes with a Chantilly mailing address, including parts of the 20152 ZIP code around South Riding, actually sit in Loudoun County. If that's you, Loudoun's rules apply instead. Our permits and HOA page walks through both.
Choosing materials
Roofing Roughnecks installs GAF Timberline HDZ, Timberline UHDZ and Grand Sequoia shingles, and CertainTeed Landmark, Landmark Pro and Presidential Shake. Roofing Roughnecks holds CertainTeed Master Craftsman credentials, Roofing Contractor and Shingle Quality Specialist, earned September 2026. The right product depends on the roof's details and, if you have an HOA, on what it will approve, so we treat color as a decision made after the scope is clear rather than before.
What the homeowner does
- Share what you've noticed: leaks, granules in the gutters, curling shingles, attic stains, or simply the roof's age.
- Check your HOA's architectural rules before picking a color, and submit for approval if required.
- Tell us about anything on the roof that isn't roofing, like solar panels, satellite dishes or skylights.
- Plan for driveway access on tear-off day and move vehicles, grills and patio furniture away from the drip line.
- Walk the property with us at closeout before the job is signed off.
What it costs
Our cost guide lists typical Northern Virginia reference ranges for full replacement: Basic $9,000–$16,000, Mid-Range $16,000–$28,000 and High-End $28,000–$50,000+. Roof size and pitch, the shingle line, the number of layers coming off and how much decking needs replacing move a roof between those tiers. If you want a feel for size before anyone climbs a ladder, the free roof-size tool on the Roofing Roughnecks site measures your roof from satellite and elevation data.
Do I need a permit to replace my roof in Chantilly?▸
Fairfax County's permit guidance lists replacement of roof shingles on a home as not requiring a permit, along with replacing less than 256 square feet of roof plywood unless the roof must be fire rated, such as on townhomes. If your home has a Chantilly address but sits in Loudoun County, check Loudoun's rules. The written scope should say who confirms this.
How do I know whether I need a replacement or a repair?▸
A single leak or a small area of damaged shingles is usually a repair. Widespread wear, multiple leak points, or a roof near the end of its life usually points to replacement. We'll inspect it and give you a straight answer.
How long does an asphalt shingle roof last?▸
Asphalt shingle roofs commonly last 20-30 years, but condition and maintenance history matter as much as age.
Who actually does the work?▸
Roofing Roughnecks is a division of Kenney Construction, the same licensed, insured and bonded company (VA DPOR #2705187519). The work isn't passed to a subcontracted third party.
