5-inch vs 6-inch gutters: which size does a Central Florida home need?
Most Central Florida homes are fine with the 5-inch K-style. The 6-inch is the right call when the roof funnels more water into fewer runs, such as large valleys, a steep pitch, long two-story runs, or a roof section that dumps into a short gutter length. We confirm the size on site.

How the two sizes actually differ
The 6-inch gutter is wider than the 5-inch, so it holds and carries more water per run before it starts spilling over the front edge.
That does not make the 6-inch automatically better. It is a sizing decision, not an upgrade. What matters is how much roof drains into each individual run and how many downspouts that run has.
A house with small roof planes and well placed downspouts moves the same water through a 5-inch gutter with no trouble. A house that funnels three roof planes into one short run can overwhelm a 5-inch even though the gutter itself is fine.
The sizes we install and what they cost
| Size | Best for | What it costs |
|---|---|---|
| 5-inch K-style | Most standard shingle roofs in Central Florida | From $7 per linear foot installed |
| 6-inch K-style | Roofs with big valleys, steep pitch, or long two-story runs | From $7 per linear foot installed |
| 7-inch K-style | Tile and metal roofs where the roofing hangs past the roof edge | Quoted per project |
Read that table again. With us, the 5-inch and the 6-inch are the same price, from $7 per linear foot installed. Nobody should be upcharging you just for going to the 6-inch.
When the 6-inch is the right call
- You see water shooting over the front of the gutter in a heavy summer rain, in the same spot every time, while the rest of the house drains fine.
- A valley dumps a whole roof plane onto one short run of gutter. All that water arrives at one point instead of spreading along the roof edge.
- One long run on a two-story elevation is doing the work of two, because there is nowhere good to put a second downspout.
- The pitch is steep enough that water comes off fast and skips instead of settling into the gutter.
When 5-inch is enough
Most single-story shingle homes in Central Florida are handled fine by the 5-inch K-style with correctly placed downspouts.
Going bigger does not fix a clog. If the gutter is packed with oak leaves and pine needles, a 6-inch just gives the debris more room to sit. That is a leaf protection question, not a size question.
Going bigger does not fix a bad pitch either. A gutter hung flat or backwards will hold water at 6 inches the same way it does at 5 inches.
What we check on site
- How much roof area drains into each individual run, not just the total square footage of the house.
- The number and position of the downspouts, and whether there is a clean path to add one.
- Valleys, and which run they land on.
- The pitch of the roof and how fast water leaves it.
- The condition of the fascia, because the fascia is what the gutter hangs on.
Where the 7-inch fits
The 7-inch is a different situation. It is for clay tile and metal panel roofs where the roofing material hangs past the roof edge, so the water leaves the roof further out than a 5-inch or 6-inch gutter can reach. It is aluminum only and quoted per project.
