Half-round on a house this size

Many of the larger homes here carry half-round gutter, or carried it once, and the round profile suits a house with this much trim. It behaves differently than the K-style on a subdivision house, though. Half-round sits in brackets screwed to the fascia or the roof deck. The brackets are what give out.

Put a long eave under a heavy tree load and space the brackets too wide, and the trough rolls forward a little every winter. Ice settles in the belly. By March the front lip sits lower than the back and water pours over the top.

Usually the trough itself is fine. We add brackets, reset the fall toward the outlet, and the run goes back to work. When it isn't fine, we'll show you the cracks and split seams in photos before anyone talks price.

Copper that has earned its green

Copper gutter on an old house can outlast two or three roofs. What lets go is the solder at the seams and at the spots where outlets drop out of the trough. A drip at a copper seam is a repair, and usually a small one. We clean the joint back to bright metal, flux it and resolder it.

We don't paint copper, and we don't patch it with a tube of sealant. Sealant on copper buys you about a season. We also won't tell you to tear out a copper system because one corner drips, since the rest of it likely has decades left. There's more on the metal itself on our copper gutters page.

Old metal, new pieces

Sometimes a section really is gone. A limb came down on it. Or somebody years ago spliced a length of aluminum into a copper run, and the two metals have been eating each other at the joint ever since. Copper and aluminum shouldn't touch. That joint corrodes fast.

When we replace a piece, we match material, profile and size. A 6-inch half-round run gets 6-inch half-round. New copper looks like a bright penny for a while and browns on its own over a few years outdoors. Our half-round gutter page covers sizes and bracket styles if you want the detail.

A canopy that fills gutters in a week

The tree cover is the reason people want to live here, and it's the reason their gutters clog. Oaks drop tassels in May and acorns in the fall. Silver maples throw seeds in spring that pack into a wet mat right at the outlet. Pin oaks hang onto brown leaves half the winter and let them go a few at a time.

On a big lot, one fall cleaning won't cover it. Two in the fall and one in late spring is closer to what these houses actually need. Guards deserve a real look on this street grid, and micro-mesh is the kind we'd put on an old house with this much overhead. Read the trade-offs on our micro-mesh guards page before you decide.

Tall eaves and old lumber

Plenty of these houses run two and a half stories, with steep roofs, dormers and porches tucked under the main eave. That means more ladder work and more corners than a ranch. It also means more places for water to slip behind the gutter.

Original fascia here is often thick old lumber that has held up remarkably well. Sometimes a past owner wrapped it in aluminum, and the wrap hides rot. We probe every bracket location before trusting it. If a few feet are soft, we cut that out and splice in new wood, primed and painted, instead of re-boarding the entire eave. Our notes on rotted fascia go further.

Downspouts on a sloping lot

Webster Groves isn't flat, and a lot of Webster Park yards fall toward the street or toward a neighbor. Water off a big roof picks up speed on a grade. A downspout emptying at the base of an old stone or brick foundation on the uphill side will find the basement sooner or later.

So we follow each downspout to where its water actually ends up. Sometimes a longer extension handles it. On the high side of the house, a buried line carried out to daylight downhill is often the honest answer, even though it's more work than a splash block.

Upgrades this house doesn't need

We won't sell you thin aluminum K-style to replace half-round on a house like this. It's cheaper this year, and it looks wrong for the next thirty.

We won't rip out copper that only needs solder. And if a built-in box gutter needs relining, that's a bigger conversation. We'll have it straight with you instead of hanging a new gutter in front of an old problem.

The things we will push for are dull ones. Brackets at tight spacing. Real solder joints. Sound wood behind every fastener.

Webster Park gutter questions

Can you repair half-round gutter without replacing the whole run?

Usually. Most half-round trouble comes from brackets spaced too far apart or pulled loose. Adding brackets and resetting the pitch cures the sag in many cases. If the trough itself is cracked or split, that piece gets replaced.

Our copper gutter leaks at a seam. Is caulk good enough?

Not for long. Sealant on copper tends to fail within a season or two. A proper fix cleans the seam to bare metal and resolders it, and that joint holds for many years.

Will new copper match the dark copper already on our house?

Not on day one. New copper starts out bright and darkens by itself after a few years outdoors. The difference shrinks every season.

Why is there a piece of aluminum spliced into our copper gutter?

Someone made a quick fix at some point. Where aluminum and copper touch, the joint corrodes. We'd swap that piece for copper so the run is one metal again.

How often do gutters need cleaning on a lot with big oaks?

Most Webster Park lots with mature oaks and maples need two cleanings in the fall and one in late spring. Guards cut that down, though even a good guard needs an occasional rinse.
