In November 2026, Loudoun Roofing replaced the roof on a townhouse in the Goose Creek Village neighborhood of Ashburn, Loudoun County, Virginia, after an October inspection found water-stained, rotting roof decking in the attic around a vent. The new roof is CertainTeed Landmark PRO in Moire Black, installed in one day, with new decking where the old decking had failed.

About Ashburn
Ashburn is an unincorporated community in eastern Loudoun County, made up mostly of planned neighborhoods built from the 1990s on, so many roofs there are reaching the age where first replacements come due. Ashburn Park, a 16-acre Loudoun County park on Partlow Road, is a neighborhood landmark. Learn more from Loudoun County.
The challenge and how we solved it
During an October inspection, the crew found water staining and rotting decking in the attic around a roof vent where the dryer duct connects. On the roof, nail heads had worked loose and rusted, several shingles were cracked, and the flashing where the roof meets the siding had been patched and was pulling apart.
With damage under the shingles as well as on top, a full replacement made more sense than spot repairs. When the old roof came off, the decking at the vent opening was rotted through, so the crew cut it out and installed new decking before the new roof went on.

Keeping your roof in good shape
- Check your attic a couple of times a year for water stains, and keep attic vents clear so moisture can escape.
- Clean your gutters after the fall leaf drop and again in spring. Clogged gutters push water back under the edge of the roof.
- After strong storms or wind warnings from the National Weather Service Baltimore/Washington office in Sterling, look over your roof from the ground for missing or lifted shingles.
- On a townhouse, make sure dryer and bath fan ducts stay connected and sealed at the roof, so warm, damp air goes outside instead of into the attic.
Frequently asked questions
Water stains or soft decking in the attic, rusted or popped nails, cracked shingles and loose flashing at the walls are common signs. The inspection on this Ashburn townhouse found all of these, so a full replacement was the better choice.
It is roof decking treated to slow the spread of fire. It is often used on attached homes like townhouses, and the crew installed new fire-rated plywood on this roof.
This one took one day on the roof, from tear-off to finished shingles. Most townhouse roofs take one to two days, depending on weather and what the crew finds under the old shingles.
Moire Black is a CertainTeed Landmark PRO color, a deep black blend.
