Reline before rebuild
A sound box gutter with a dead lining does not need to be torn out. Relining a trough that still has good wood under it is usually the right call, and it costs a fraction of a rebuild.

Box Gutters in Northern Virginia
A box gutter is part of the roof, not something hung off it. That means when one leaks the water goes into the structure instead of down the siding, and you usually find out from the ceiling.

Overview
Box gutters show up on rowhouses, older Virginia homes, and commercial buildings because they move serious water, and they fail quietly because the failure happens inside the roof edge.
Most of the box gutters we open up are not failing because the trough is the wrong size. They are failing because the lining is at the end of its life, or because someone patched a seam with roof cement ten years ago. We find the actual failure, repair the wood under it, and reline the trough in a material that belongs there.
Rot gets replaced
Lining over soft wood buys a season. We pull the old lining, cut back to solid framing and decking, replace what is gone, and only then start building the new trough surface.
Outlets sized to the roof
Big roofs put a lot of water into a box gutter fast. We size outlets and downspouts to the drainage area using the 6.5 inch per hour rate Virginia designs to, not to whatever hole was already there.
Detail
How we approach a box gutter
Every box gutter is a little different, because most of them have been repaired by somebody before us. We start by finding out what is actually holding water and what is just old.
- Inspection firstWe get in the trough, check slope, probe the wood at the low points and the outlets, and look at the ceiling and wall below. The inspection is free and you get the photos whether you hire us or not.
- Lining optionsEPDM membrane works well in a wide flat trough and runs in the same material family as a flat roof. Soldered metal lining suits historic work and narrow troughs. We tell you which one fits the trough you have.
- Tie in to the roofThe lining has to run up under the roofing at the back edge, not stop at it. That transition, plus ice and water shield at the eave, is where most box gutter leaks are actually born.
- Commercial and multi buildingApartment blocks and rowhouse runs often share one continuous box gutter across several units. We stage that work so no unit is left open overnight, and every section is photographed by address on CompanyCam.

Questions
Box Gutters questions we get asked
What is a box gutter?
A large rectangular trough built into the roof structure rather than hung on the fascia. You see them on older homes, rowhouses, and commercial buildings with big roof areas. Because the trough is part of the building, a leak drains into framing and ceilings instead of running down the outside wall.
Can an old box gutter be relined instead of rebuilt?
Often yes. If the framing and decking under the trough are solid and the slope still runs to the outlets, a new lining is the correct repair. We only recommend a rebuild when the wood is gone or the trough has no fall left in it at all.
Why does my box gutter leak in the same spot every year?
Because it has been patched, not repaired. Roof cement and tape over a failed seam last a season or two, then the joint moves again with temperature and opens back up. The fix is continuous lining through that area rather than another patch on top of the last one.
Do you work on commercial box gutters?
Yes. Larger commercial and multi building box gutter work is a regular part of what we do, including the flat roof surfaces those troughs usually tie into. Most residential roofers in the DMV have never lined a box gutter, so ask any bidder what they last relined.
What does box gutter work cost?
It depends entirely on how much wood is bad, which nobody can tell you from the ground. We inspect, show you photos of the trough, and give you a written estimate with the rot repair broken out separately so you can see what is condition and what is scope.

Keep them working
New gutters only work if they stay clean.
A seamless run, a new downspout or a re-pitched trough still fills with leaves, seed pods and shingle grit. Cleaned on a schedule, gutters drain the way they were built to. Every visit we clear each trough by hand, flush every downspout and check the hangers and pitch. We don’t install gutter guards. See why.
