Roofing in Herndon, VA: Repairs, Replacements and Flat Roof Sections
Reston Roof works from Reston and serves houses, townhouses and small buildings in Herndon. We start every job by working out which office issues the permit.
What We Do for Herndon Roofs
Most of our roofing is residential: replacement and repair on houses and townhouses, chimney leak repair, emergency storm repair and tarping, small repairs and roofs for gazebos and other small structures. We also take on some commercial roofs and the flat or low-slope sections that sit beside pitched roofs. Reston is next door, so Herndon visits are a short drive down Baron Cameron Avenue, which turns into Elden Street at the town line.
If you want to know what a roof will involve before anyone climbs up, call (571) 453-6515 or book a phone consultation. We will ask about the age of the roof, where it leaks and which part of Herndon you are in.

Phone ConsultationThe First Question: Town or County?
The Town of Herndon was incorporated on January 14, 1879, covers about 4.3 square miles and had 24,655 residents at the 2020 census. Inside those limits, the Town's own Building Inspections office issues building permits, not Fairfax County. The Town's re-roof paperwork asks for a Re-Roof Form and either a state contractor license or an owner's affidavit, plus proof of zoning approval for properties in the historic district.
Many addresses that say Herndon, with ZIP code 20170 or 20171, sit outside the Town. Oak Hill, Floris, Franklin Farm and McNair are unincorporated Fairfax County, so Land Development Services is the permit office there. We check your address first and confirm with the right office before we start. Our Fairfax County roofing permits guide explains the county rules in plain language.
What Herndon Roofs Look Like on Paper
The Census Bureau's 2020 to 2024 American Community Survey counts 8,076 homes in the Town: 3,532 detached houses, 2,196 attached townhomes and 2,202 homes in buildings of five or more units. The median year built is 1983, and 56.1 percent of the homes went up between 1970 and 1989. About 42.7 percent pre-date 1980. The survey does not record roof material, so these figures say little about what is on top. Our reading is that most original roofs from those decades have been replaced at least once, and the flat sections and add-ons are often a different age from the main roof.
Herndon is more house-heavy than Reston: detached homes are the largest group, with townhouse rows and multi-unit buildings close behind.
Old Downtown, and the Historic District Overlay
Herndon's downtown core was largely rebuilt after a 1917 fire, and the Herndon Historic District around it includes houses from 1890 to 1920. The Herndon Depot Museum is on Lynn Street. The Town has a Historic District Overlay with a Historic District Review Board, and a roof material or color change in the overlay should go to the Town's historic district staff first. A 2023 news report on the updated overlay map placed the Fortnightly Square townhomes, built in 2005, inside it, so age alone does not tell you.
We have not seen a Town rule that exempts a like-for-like roof replacement, so we ask. For homeowners in subdivisions with an association, a separate set of covenants may apply, and the Town does not review them.
Weather That Tests Herndon Roofs
On April 6, 2017, an EF0 tornado formed just west of Herndon Parkway and crossed about three miles to the northeast. The National Weather Service rated peak winds at 70 mph, and the damage was mostly to trees and fences. A derecho on June 29, 2012 gusted to 71 mph at Dulles International Airport, the nearest weather observation point. Snow matters too: Dulles recorded a preliminary record of 73.2 inches in the 2009 to 2010 season.
Trees are the other factor. A 2025 report put Herndon's canopy near 26 percent, and the Town has been trimming and removing hazardous trees. After a storm, limbs on a roof are a common problem, and we document damage with photos for your claim.
Flat Roofs and Special Materials, Page by Page
Pitched shingle work is the core of what most homeowners need. For the flat or nearly flat parts of a roof, and for metal, we have a page for each material, written for Herndon.
- TPO roofing in Herndon: heat-welded membrane for townhouse flat sections, multi-unit buildings and small commercial roofs.
- EPDM roofing in Herndon: rubber sheet for porches, additions and garage roofs on older houses.
- PVC roofing in Herndon: for kitchen exhaust, crowded flat roofs and old flashing that has to be isolated.
- Metal roofing in Herndon: standing seam and screw-down panels for houses, dormers and garages.
Great local roofing experts with very reasonable pricing versus the big roofing companies. They were quick, courteous, and diligent.

Getting to the Job: Herndon Roads and Access
Access shapes roof work as much as weather. Elden Street is a six-lane commercial corridor, Sterling Road carries the same route west toward Loudoun County, and Dranesville Road is the northern name of state route 228. Herndon Parkway is the truck route around the west side of downtown, and the Fairfax County Parkway follows the town's eastern border. The Dulles Toll Road meets route 228 near town. For roofs near these roads, we plan where trucks can stage and whether a dumpster fits.
Our neighbors on the map include Reston, Sterling, Chantilly and Great Falls, and Oak Hill sits between Herndon and Chantilly. The full list is on our service areas page. Frying Pan Farm Park in Oak Hill is a handy landmark when you describe where you live.
Frequently Asked Questions
How do I know if my Herndon address is inside the Town of Herndon?
A Herndon mailing address does not settle it. The Town is an incorporated town of about 4.3 square miles, while Oak Hill, Floris, Franklin Farm and McNair are unincorporated parts of Fairfax County that can carry a Herndon mailing address. When you call, we confirm which jurisdiction applies before we plan anything.
Do I need a permit to replace my roof in Herndon?
Inside the Town, the Building Inspections office issues permits, and the Town publishes a Re-Roof Form, so we do not assume a replacement is exempt. We confirm with the Town before we start. In unincorporated Fairfax County, the County's own list says replacing roof shingles needs no permit, but roof repairs, chimney repairs and large decking replacements can. When it is unclear, we ask the office before any work begins.
Does the Herndon Historic District affect my roof?
It can. The Town's Historic District Overlay is reviewed through Certificates of Appropriateness, and the Town's re-roof application asks for proof of zoning approval when the property is in the district. Changes to roof color, material or style should go to Town historic district staff first. A National Register listing alone does not bind owners; the local overlay does, and the Town's map decides which houses are inside it.
What kinds of roof work does Reston Roof do around Herndon?
Mostly residential: full roof replacements and repairs on houses and townhouses, chimney leak repair, emergency storm repair and tarping, small repairs, and roofs for gazebos and other small structures. We also do some commercial work and flat or low-slope sections using TPO, EPDM, PVC or metal. For larger commercial roofs we talk through the scope on site before promising anything.
My roof is leaking right now. What should I do first?
Protect the inside first: move belongings and put a bucket under the drip. Do not climb onto a wet roof. Take photos of the damage, then call us at (571) 453-6515. If a tarp is needed, we can arrange a temporary cover and plan the permanent repair. We document damage with photos for your claim.
