Gutter guides
By Gutter Report Editorial. Last reviewed August 2026. How we research this.
In brief
The cost pages tell you what things cost. These pages tell you what to buy. Every one ends in a recommendation rather than a list of factors, because a page that lists factors has handed the decision back to you. Start with repair or replace, because it decides whether the rest matters at all. Repair averages $275 to $399 across four publishers, and replacement runs $2,200 to $5,000 at HomeGuide, so getting that one wrong is the most expensive mistake on this site. If you are replacing, the order that saves money is size first, then material, then seamless or sectional, then profile, then guards. Size comes first because changing it later means doing the whole job over. Guards come last because they are the one item here you can add at any time, years after the rest is done. Every page below names its sources and the date we read them.
1.0Start here
| Guide | The decision it makes |
|---|---|
| Repair or replace | The one that decides the others. Includes the crossover point where patching stops paying |
| Which material | Aluminum, copper, steel and vinyl on one table, with a verdict per situation |
| Seamless or sectional | What the $3 to $5 a foot premium buys, and the two cases where sectional wins |
| K-style or half round | A look decision more than a drainage one, and the page says so |
| Do it yourself or hire | What you save, what it costs to get wrong, and what is not available to buy |
| Are gutter guards worth it | A payback test on your own house, not a product review |
2.0Sizing and specification
These are the pages a contractor should already know and often skips. They are also where the published numbers are most often reprinted wrong.
| Guide | What it answers |
|---|---|
| Gutter sizes | The full sizing method, roof area to gutter size, with the rainfall input the reprints leave out |
| How many downspouts | Nine sources, three different rules, and which to use |
| Gutter slope | Four published standards, two and a half times apart, and what that means for your run |
| Gutter hangers | Types, spacing, and why a sag is almost always this and not the gutter |
| How installation works | The whole job in order, so you can tell what you are watching |
| Seamless gutter machines | The machine that makes seamless contractor only, and what it costs |
3.0The order that saves money
If you are replacing, decide in this order. Each step narrows the next one, and going out of order is how people end up paying twice.
- Size. Roof area, pitch and local rainfall set it. Getting it wrong means redoing the job, not adjusting it. See gutter sizes.
- Downspouts. Cheaper capacity than a bigger gutter, and it changes where the outlets go. See how many downspouts.
- Material. Sets the price band and the service life. See the material comparison.
- Seamless or sectional. Only a real choice in metal, and it depends on the material you just picked. See seamless against sectional.
- Profile. Mostly a look decision. See K-style against half round.
- Guards. Last, and separable. You can add them in five years. See are guards worth it.
4.0You may not be replacing at all
Most people who reach a site like this arrived with a symptom, not a plan. Water over the front edge in heavy rain, a drip at a joint, a section pulling away from the house, or a stain appearing on the soffit. Not one of those is a reason to replace gutters by itself.
Overflow is usually slope, a clog, or too few downspouts. A drip is a seam. A sag is a hanger or the fascia behind it. Work through repair or replace before you price anything else, and price the fix on the repair cost page. We can say that plainly because we do not sell gutters and we do not install them.

Common questions
What is the most expensive gutter mistake?
Replacing a system that needed a repair. Repair averages $275 to $399 across four publishers. Replacement runs $2,200 to $5,000 at HomeGuide. Most calls about leaks and overflow turn out to be a seam, a hanger, a clog or a slope problem, and none of those needs new gutter. The repair or replace guide walks the test.
Which decision should I make first?
Whether you are repairing or replacing. Everything else follows from it. If you are repairing, material and profile do not matter, because you keep what you have. If you are replacing, work in this order: size, then material, then seamless or sectional, then profile, then guards. Size is first because it is the one you cannot change later without doing the job again.
Do I need a bigger gutter or more downspouts?
Usually more downspouts, and it is much cheaper. Fine Homebuilding states that going from one outlet to two doubles the roof area a run can drain. Moving from 5 inch to 6 inch buys about 40 percent, per Englert. Adding an outlet also fixes the case a bigger gutter cannot: water concentrated at one spot, like the bottom of a valley.
Can I do any of this myself?
Some of it. Cleaning and simple sealing are homeowner work. Vinyl gutter snaps together and can be fitted by hand. Seamless cannot be, because the gutter is rolled to length by a machine on a contractor truck, so there is no seamless product to buy. Ladder work above one story is where most of the real risk sits, whatever the job.
