In September 2026, Loudoun Roofing fixed a roof leak on a detached brick garage in the Old Waterford Knoll neighborhood of Leesburg, Loudoun County, Virginia. Water was getting in around an old pipe flashing and had soaked the board decking underneath, so the crew replaced the damaged boards, installed a lifetime pipe boot and re-shingled the area with CertainTeed Landmark in Weatherwood to match.

The challenge and how we solved it
The roof on this garage was fairly new, but water was getting in around an old pipe flashing that was lifting the shingles around it. Inside, the board decking under that spot was wet and stained. A framing nail had also pushed up through a shingle nearby.
The homeowner asked whether the leak could be fixed without removing any shingles. It can’t: the wet decking sits under the shingles, so the only way to reach it is to open up the roof. The crew removed the shingles in about a 3 by 6 foot area, replaced the damaged deck boards, installed a new lifetime pipe boot over ice and water shield and replaced the shingles where the framing nail had popped. Because the roof was relatively new, a lifetime pipe boot made sense.
Before
What we did
- Inspected the leak from inside and on the roof.
- Removed the shingles in about a 3 by 6 foot area around the leak.
- Replaced the wet, damaged deck boards with new 1×8 boards.
- Installed ice and water shield around the pipe and a new lifetime pipe boot.
- Replaced two shingles where a framing nail had pushed through and checked the wood under them.
- Re-shingled the repair area with CertainTeed Landmark in Weatherwood.
- Sealed and checked the repair.
The finished project
Why these materials
Lifetime pipe boot over ice and water shield. A lifetime pipe boot is built to last as long as the roof, and the ice and water shield underneath adds a second layer of protection around the pipe.
CertainTeed Landmark shingles in Weatherwood. Landmark is CertainTeed’s dual-layer architectural shingle. CertainTeed lists a lifetime limited transferable warranty, a 110 mph wind rating (upgradable to 160 mph), a UL Class A fire rating and UL 2218 Class 3 impact resistance. Details are on CertainTeed’s Landmark page. See our CertainTeed Landmark page for more.
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.
- Keep an eye on the area around roof pipes. A lifting flashing or cracked boot is one of the most common leak sources on a newer roof.
Frequently asked questions
Usually not when the decking under the leak is wet. The shingles have to come off to replace the damaged wood. On this Leesburg garage, the crew opened about a 3 by 6 foot area.
A worn or lifting pipe flashing or a cracked pipe boot lets water run down the pipe and into the decking. Here, the old flashing was lifting the shingles around it.
This repair came with a 2-year labor warranty from Loudoun Roofing.
Some roofs have decking made of individual wood boards instead of plywood sheets. Damaged boards can be replaced one at a time, as they were here with new 1×8 boards.
