Waunakee seamless gutters fail from underneath. A gutter full of water is heavy and stable; an empty one on an exposed eave is a long aluminium airfoil, and wind gets under it and lifts. On open ground north of the lakes, hanger type and spacing matter more than gutter size does.
Four things, and the first one accounts for most of what we get called about here.
Wind under the gutter
An empty gutter on an exposed eave catches wind from below. The force is upward, which is exactly the direction spike-and-ferrule fastening is worst at resisting. On a Waunakee lot, hidden hangers screwed into the fascia at tightened spacing are not an upgrade — they are the baseline.
The old system
Older gutters were hung with long spikes driven through the gutter into the fascia. They loosen over time as the wood works around the spike, and on an exposed eave they work loose much faster. If you can see gaps between the gutter and the fascia, that is what is happening.
Not leaves
With little tree cover, Waunakee gutters do not clog with maple seed. They collect agricultural and airborne debris from open ground upwind, which is finer and behaves differently. Mesh guards designed for leaves are often the wrong product here.
Freeze-thaw
Snow melts off a warm roof and refreezes at the cold eave. Gutters do not cause ice dams, but a gutter already loosened by wind uplift will not survive the added ice load. The real fix is ventilation and insulation, and we will say so rather than selling you gutters.
New seamless systems, guards, drainage, and the repairs that are worth doing versus the ones that aren’t.
Screwed into the fascia at tightened spacing. The correct system for an exposed eave and what we install by default.
Replacing loosened spike-and-ferrule fastening without necessarily replacing the gutter.
Formed on site to the exact run length. No seams means no seam leaks.
Spikes working loose over years chew up the fascia behind them. We replace rather than screwing into damaged wood.
Fine debris behaves differently from leaves. The right screen matters more than whether you have one.
Extensions and underground drains to get water away from the house.
Two-story elevations and difficult access move the number. Fascia replacement is quoted at the estimate once we can see behind the existing gutter — on a house with old spike fastening, expect to find some.

Wind uplift acting on spike-and-ferrule fastening. An empty gutter on an exposed eave catches wind from underneath, and the force is upward — the direction spikes resist worst. Over years the wood works around the spike and the gutter starts to sag away. Converting to hidden hangers screwed into the fascia usually solves it without replacing the gutter.
A spike is a long nail driven through the gutter into the fascia. A hidden hanger is a bracket that clips into the gutter and screws into the fascia, spreading the load and resisting uplift far better. Spikes were standard for decades and they are still used because they are fast. On an exposed Waunakee eave we do not install them.
Less often than in a neighbourhood with mature trees, and if you do, the product matters. Waunakee gutters collect fine airborne and agricultural debris from open ground rather than leaves and maple seed. Mesh sized for leaves passes fine debris straight through, so it accumulates anyway. We will tell you honestly if your lot does not warrant guards.
On most Waunakee homes, no. Six-inch matters where a valley concentrates a large roof area into a short run. On a standard roofline, correctly hung 5-inch with a properly sized downspout is genuinely fine — and on this lot, how it is hung matters more than how wide it is.
No, and anyone who tells you otherwise is selling. Ice dams come from heat escaping into the attic, melting snow that refreezes at the cold eave. Gutters make the resulting damage worse when they are full or already loosened. The real fix is ventilation and insulation, which we also do.
