A stain on a bedroom ceiling rarely sits directly under the hole that caused it. Water runs along decking, rafters and the top of drywall before it shows up inside, which is why a good roof repair starts with diagnosis rather than a tube of sealant. When a Chantilly homeowner calls about a leak, our first job is to trace it to the real source: a cracked pipe boot, a lifted shingle, failed flashing at a wall or chimney, or a ventilation problem that's causing condensation and looks like a leak.
Roof repairs we handle
- Leak diagnosis and repair.
- Replacement of damaged, missing or creased shingles.
- Flashing repair at chimneys, walls, dormers, skylights and valleys.
- Correction of ventilation issues that cause recurring problems.
- Repairs to low-slope and flat roof sections over porches and additions.


These photos are from a flat roof repair over a covered front porch and balcony in Oakton, a few miles east of Chantilly. Low-slope sections like that one are a common source of leaks on otherwise healthy roofs because water drains slowly and seams matter more. We've written a separate guide on porch and addition roofs if that's what you're dealing with.
Repair or replace: how we decide
The honest answer depends on the extent of the damage and the age of the roof. A single leak or a patch of storm-damaged shingles on a roof with plenty of life left is a repair. Several leak points, widespread granule loss, or shingles that are brittle enough to crack when you lift them usually mean you're paying to patch a roof that's finishing anyway. When it's close, we'll explain both options in writing so you can compare them rather than taking our word for it.
Permits and Fairfax County
Fairfax County Land Development Services lists roof repairs among the miscellaneous residential work it issues permits for, while straight replacement of roof shingles appears on its list of work that doesn't need a permit. Where a particular repair falls is the county's call, not ours to guess, so the written scope says whether a permit applies and who is responsible for pulling it. The county recommends that a licensed contractor pull permits as the responsible party.
What you can do before we arrive
- Photograph the ceiling stain or drip and note when it shows up: every rain, only wind-driven rain, or after snow.
- If it's safe, look in the attic with a flashlight for wet decking, dark rings around nails or damp insulation.
- Put a bucket under active drips and move valuables. Don't climb onto a wet roof.
- Find any paperwork on the roof's age or previous repairs.

Typical Northern Virginia reference ranges from the Roofing Roughnecks cost guide, not a quote for a Chantilly roof. Your written estimate is based on an inspection of your actual roof.
Can you repair just part of my roof?▸
Yes. Targeted repairs for leaks, damaged shingles, flashing and ventilation issues are a core part of what Roofing Roughnecks does. Matching very old shingles exactly is not always possible, and we'll tell you up front if a patch will be visible.
Why does my roof leak only in heavy, wind-driven rain?▸
That pattern often points to flashing at a wall, chimney or dormer, or to lifted shingles that let water in sideways. It needs an inspection to confirm.
Do you repair flat roofs over porches?▸
Yes. Low-slope and flat sections over porches and additions are part of our roof repair work, as on the Oakton porch project shown on this page.
