What the homeowner said
Sara T.
Highly impressed with Loudoun Roofing. I had several companies come look at my roof, Loudoun Roofing was the only one that showed me pictures of the inside and outside, explained all the issues with the roof, underlayment, flashing. In fact, they’re the only ones to discover that the exhaust fans for the bathrooms weren’t even vented to the outside. They were great communicators, extremely professional and clean, and they take great care in their work.

The challenge and how we solved it
The leak traced back to the aluminum ridge vent running along the peak of the roof. Ridge vents let hot, moist air out of the attic, but when the vent or its seal fails, rain can get in right at the highest point and run down into the house.
Patching the vent wouldn’t have fixed an aging roof, so the crew replaced the roof and the ridge ventilation together, so the new shingles and the new vent are sealed as one system.
Two roof vents sat where the new ridge vent would have blocked them, so the crew moved both. A third-party solar company removed the home’s solar panels before the tear-off and reinstalled them afterward, and we made sure the roof was leak-free once they were back on. The crew also replaced the gutters with new 5-inch K-style gutters.

Keeping your roof in good shape
- Keep the ridge vent clear. Don’t let anything sit on or block it, and have any roof vent near it checked if you ever see stains on ceilings near the peak.
- 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.
- Keep tree limbs trimmed back from the roof so branches don’t scrape shingles or drop debris into valleys.
- Check your attic a couple of times a year for water stains, and keep attic vents clear so moisture can escape.
- In winter, watch for ice building up along the eaves. Heavy ice dams are worth a call.
Frequently asked questions
Usually a failed seal, a cracked or dented vent, or nails that have backed out. Wind-driven rain in Loudoun County storms finds those gaps fast, and the water enters at the highest point of the roof.
Sometimes. If the shingles are in good shape, the vent can be replaced on its own. On an older roof, replacing the vent and shingles together usually makes more sense, which is what this homeowner chose.
Colonial Slate is a CertainTeed Landmark PRO color with blended gray and dark tones, chosen to look like a slate roof.
Most homes this size are done in one to two days, depending on weather and what the crew finds under the old shingles.
