Why is the stain far from the actual hole?

Water follows beams and wall cavities from the failure point and drops where it runs out of road, so the source is traced at the trough.

Box Gutter Repair in Brevard County, Florida (FL)

Q: How do I know my building has a box gutter at all?

If the roof meets a parapet or no gutter is visible from the street on an older building, water runs through a built-in trough.

Q: Can you reline the gutter without touching the rest of the roof?

Usually yes. The liner sits inside the trough and ties into the surrounding covering at the edges.

Q: What if the gutter boards are rotten?

The survey report says so with photographs and prices the rebuild as its own line before any work starts.

Across Brevard County, we keep the box gutters of old storefronts, farmhouses and mills doing their quiet job: survey first, then a liner or rebuild priced in writing.

What a box gutter is, and why yours leaks

A box gutter does not hang off the roof edge. It is built into the roof itself: a timber trough lined with metal or membrane, running behind a parapet wall or tucked between two roof slopes. Nearly every American building put up before 1950 with a flat front, and most commercial roofs since, drains through one.

That hidden position is the whole problem. A hanging gutter fails in public, dripping where you can see it. A box gutter fails inward. The trough floor rusts through or a joint opens, and the water takes the shortest path into the building: along a beam, down a wall cavity, out through a ceiling ten feet from the actual hole.

By the time a stain appears, the leak has usually been running for seasons. This is why we open every job with a survey rather than a sales pitch. Someone has to stand in the trough, meter the timber and find out which of the six classic failures is at work before any fix is worth pricing.

Surveying a box gutter behind a brick parapet on a commercial roof

The six ways a trough gives up

Failure	What you notice	How serious
Rust-through	Brown staining creeping along one ceiling line	Urgent, the trough floor is opening
Ponding	Water still standing in the trough days after rain	Serious, rust and split joints follow
Joint split	A leak that only arrives with hard rain	Moderate when caught early, patchable
Parapet overflow	Damp patches high on an outside wall	Serious, masonry soaks from the top down
Blocked outlet	Overflow at one corner in a downpour	Simple to clear, expensive to ignore
Sagging boards	The gutter line visibly dips mid-run	Structural, this is a rebuild conversation

Every survey checks all six, photographs what it finds and writes down which ones your roof actually has.

Lining options, with their honest lifespans

Option	Expected life	Relative cost	When it is the right call
Folded metal liner	40 to 60 years	Higher	Sound timber, long straight runs, an owner who intends to keep the building.
EPDM rubber liner	25 to 35 years	Middle	Awkward shapes and junctions, or when the roof must be weathertight by tonight.
Liquid membrane	10 to 20 years	Lower	Buying honest time on a trough that is tired but structurally sound.
Full rebuild	The next sixty years	Highest	When boards, bearers and liner have all given up at once.

The survey decides this, not the brochure. When a coat of liquid is the wrong answer we say so, and when it is the right one nobody will talk you into a rebuild.

Troughs we have stood in

**Decay, found early**Fifty quiet years look like this. Catching a trough at this stage is the whole game.

**Folded metal liners**Galvanized or stainless sections folded to the trough and locked over sound timber.

**EPDM lining**One rubber membrane, welded seams, no joints left for the frost to open.

**Liquid membranes**Rolled wet onto a prepared trough, reinforced at every junction and outlet.

**Outlets and grates**A new drain head under a leaf grate, because most floods begin at a blocked outlet.

Homes, mills and main streets

Houses with history

Victorians, foursquares and rowhouses hide their gutters behind cornices and crown moldings, exactly where a ladder inspection never looks. The trough is often original, which means a century of patches over the first liner.

We work from the roof, keep the cornice profile intact and match liner details to the age of the house. The neighbors notice fresh paint, not our scaffold.

Commercial roofs and old mills

Parapet gutters on flat commercial roofs feed internal downpipes, so one blocked outlet can put water through three floors of stock. Mills and warehouses add long spans and valley troughs measured in hundreds of feet.

We schedule around trading hours, document every finding for owners and insurers, and can put the trough on a standing maintenance rota so the next blockage never becomes a claim.

Four moves, one dry building

ZIP code, what the gutter is doing, your name and number. Photos can wait for the survey.
2
The roof survey
We walk the trough end to end, meter the timber, photograph every junction and lift what needs lifting.
3
The report and the quote
One document: what is failing, what can wait, and what each fix costs. You keep it whichever way you decide.
4
The repair or the reline
Liner in, outlets flowing, and a hose test before the ladder comes down for the last time.

The price of a dry trough

Job	Typical bracket	What it covers
Roof survey and written report	Free	Findings, photos and prices, yours to keep.
Patch and joint repair	$260 - $700	Seam resealed or a liner patch, leak traced first.
Reline in folded metal	$34 - $60 / lin ft	New metal trough liner over repaired boards.
Reline in membrane	$22 - $42 / lin ft	EPDM or liquid system, junctions reinforced.
Full trough rebuild	$90 - $180 / lin ft	New boards, bearers, liner and flashings.
New outlet and leaf grate	$320 - $850	Drain head cut in, sealed and grated.

Length, access and how far the rot has traveled set the final number. The survey settles all three, and the survey costs nothing.

Asked from under a stained ceiling

How do I know my building has a box gutter at all?

If the roof meets a parapet wall, if the front of the building is flat with no gutter visible from the sidewalk, or if two roof slopes meet over a wall, water is running through a built-in trough. Buildings put up before 1950 nearly always drain this way.

Why is the stain ten feet from where you found the hole?

Because water is a traveler. It leaves the trough at the failure, follows a beam or a wall cavity, and only drops when it runs out of road. Chasing the stain instead of the source is how buildings end up with three patches and the same leak.

Can you reline the gutter without touching the rest of the roof?

Usually, yes. The liner sits inside the trough and is independent of the slates, shingles or membrane around it. We tie the new liner into the existing covering at the edges, and the rest of the roof never knows we were there.

Metal or membrane, which liner should I want?

The honest answer is the one that fits your trough, not the one with the best margin. Sound timber and straight runs favor folded metal for its lifespan. Twisting runs, many outlets or a tight budget favor rubber or liquid. The report prices what fits.

How disruptive is the work for the shop or offices below?

Less than a leak is. Nearly everything happens at roof level behind edge protection. Trading continues, and for occupied commercial buildings we sequence noisy cutting outside the hours that hurt.

What if you find the gutter boards are rotten?

Then the report says so, with photographs, and prices the rebuild as its own line. Nobody discovers a doubled invoice halfway through the job. Rot found at survey stage is a plan; rot found mid-reline is an argument, and we prefer plans.
