A roof leak in Manassas rarely shows up where the water gets in. Rain follows the rafters and drops off a nail or a duct, so the brown ring on the ceiling can sit several feet from the opening.
The roofer checks the usual entry points first: chimney flashing, plumbing vent boots, valleys, skylight curbs and the spots where a dormer meets the main slope. Wind-driven rain from a thunderstorm finds the weak one fast.
Most leak repairs cost $400 to $2,000. Chimney flashing runs $500 to $2,000 and a skylight reflash runs $400 to $1,500. Access, roof pitch and how long the leak has soaked the insulation change the price.
Wet insulation and dark decking in the attic tell the roofer how long water has been getting in. Houses near Old Town Manassas and Georgetown South with older flashing often show the same pattern around the chimney.
Technician insight
The stain on a Manassas ceiling shows where water landed, not where it entered. The roofer starts in the attic and follows the wet wood uphill.
