Buying Gutters: The Complete Homeowner Guide, Step by Step

By Pittsburgh Gutter Repair · October 15, 2026 · 8 min read

Buying gutters in Pittsburgh is mostly a matter of asking the right questions in the right order: what's actually wrong, whether it needs fixing or replacing, what to buy if it's the second, and who to hire. This gutter buying guide is the short version of everything on the site, in that order, with a link to the longer post for each step. If you read nothing else before getting a quote, read this.

Why gutters matter on a Pittsburgh house

A gutter's job is simple: catch the water coming off the roof and put it somewhere away from the house. On a flat lot in a dry climate, a missing gutter makes a wet flowerbed. Here, with about 38 inches of rain and 28 inches of snow a year, clay soil that holds water, and many houses sitting on a slope with a stone or block foundation, the gutter is the first line of defense for the basement, the fascia, the siding and any retaining wall downhill of the house. That's why rain gutters in Pittsburgh are worth more attention than the price of the metal suggests.

Diagnose first

1. Work out what's actually wrong

Most gutter problems in Pittsburgh are one of five things: a corner or seam that freeze-thaw has opened; a run that's sagged because spike hangers backed out; a downspout that's too small or too few for the roof; a downspout that ends at the foundation or in a dead drain; or, on a pre-1930 house, a box gutter lining that has failed. Only the last one is expensive.

Twenty minutes with a hose sorts the first four. How to find a gutter leak walks through the test, and why gutters overflow explains the overflow that isn't a leak at all.

2. Decide between repair and replacement

The rule: aluminum or copper, under 20 years old, trouble in a few spots — repair. Sectional, rusting steel, or more than a third of the runs with problems — replace. The arithmetic, with prices for both, is in repair vs. replacement, and how long gutters last covers the lifespan of each material in this climate.

These are typical market ranges, not quotes; the house, the access and the condition of the fascia move every one of them.

What to buy when buying gutters in Pittsburgh

3. Know the spec before you get quotes

Residential seamless gutters in .032-gauge aluminum, hidden hangers at 24 inches or closer, 3x4 downspouts, one downspout per 35 feet, extensions to six feet from the wall. Six-inch gutter on big roofs and under slate or metal. That's the whole spec, and what the price per foot buys explains each line and what it costs. Half-round on older houses where the look matters; copper where the house already has it.

4. Size it for the roof

The downspout is the bottleneck, not the gutter. A 2x3 handles about 600 square feet at a Pittsburgh storm rate; a 3x4 about 1,200. Measure the roof area feeding each run and the downspout count follows. The downspout math has a worked example.

5. Get the water away from the house

Whatever you do to the gutters, the downspouts have to end at least six feet from the foundation, on ground that slopes away, and not in the sanitary sewer. On a hillside, downhill of the house and any retaining wall. This is the cheapest thing on the list and it fixes more basements than anything else; downspouts and your foundation covers the soil and the local disconnection rules.

Guards and timing

6. Guards: only under the right trees

Micro-mesh under maples (the seeds go through everything else), screen under oaks and sycamores, nothing under two small ornamentals. Avoid solid reverse-curve hoods on north-facing eaves here; they ice over. Payback under heavy trees is six to eight years. The fall leaf post has the tree-by-tree guide and the guards page the prices.

7. Time it for the season

Reseal and re-hang in warm weather; sealant doesn't cure below about 40°F. Clean in the second half of November, after the oaks. Heat cables, if you need them, go on after that cleaning and before the December freeze. Ice damage shows up in March, which is when local gutter crews are busiest, so booking an inspection before then is easier. Winterizing has the list, the storm-season checklist the September walk-around, and heat cables the de-icing decision.

If the house is old

8. If the house has box gutters

Pre-1930 brick with a deep cornice and no visible gutter: it's built in. Relining in EPDM or copper is the fix; nailing an aluminum gutter over the front of it is the thing to refuse. Prices are per foot and the wood decides most of it. Box gutter repair explains it.

Hiring, and what to do this week

9. Hire properly

Ask for a written, itemized quote — gauge, hangers, downspouts, corners, fascia per foot, haul-away — with the contractor's Pennsylvania home improvement registration number on it. For the state's registration and written-contract rules, and to look the number up before signing, check with the Pennsylvania Attorney General's office (HICPA registration lookup). Ask for a certificate of liability and workers' compensation insurance issued by the contractor's agent. Be wary of a today-only price. How to read a gutter quote goes through a gutter estimate line by line, the about page lists what to expect from any gutter company, and the pricing page has the full tables so you can check any quote against them.

10. What to do this week

Walk around the house in the rain with a flashlight. Note every downspout that isn't discharging somewhere sensible, every corner that drips, every run with a belly in it. That list is your estimate request. Send it with a few photos and you'll get a more accurate price over the phone, and a shorter visit. The gutter repair page is the place to start for most houses; installation if the gutters are done.

Mistakes that cost money when buying gutters

• Comparing totals instead of line items. Two quotes a few hundred dollars apart can be the same job, or very different ones. Put the gauge, hanger type, hanger spacing and downspout size side by side before you look at the price.
• New gutters, old downspout endings. Spending $2,000 on the trough and leaving every downspout dumping at the foundation wall keeps the wet basement you started with.
• Guards on a house with no big trees. If nothing taller than the house stands within reach of the roof, a yearly cleaning costs less than guards will over their life.
• Spikes on a new install. A brand-new run hung on spike-and-ferrule hardware is a sag waiting for its third winter. Ask for screwed hidden hangers in writing.
• Booking a reseal for December. Sealant needs warm, dry metal to cure. A cold-weather reseal often has to be redone in spring.
• Covering a failed box gutter. A hung gutter nailed over a rotting built-in trough hides the leak; it doesn't stop it.

A short list of questions for any contractor

1. What gauge is the aluminum, and is that printed on the quote?
2. What hangers, and how far apart?
3. How many downspouts, what size, and where does each one end?
4. Is fascia repair priced per foot, and how will I know how much was replaced?
5. Is removal and haul-away of the old gutters included?

Common questions

What do gutters do for a house?

They collect the water that runs off the roof and carry it to downspouts that discharge it away from the walls. Without them, roof water lands in a line along the foundation, splashes mud onto the siding and soaks the fascia and the soil next to the basement. On clay soil and sloped lots like most of Allegheny County, that water tends to end up inside.

Why are gutters important on a house in Pittsburgh?

Because the ground here doesn't drain well and many houses sit on a slope. Clay holds water against the foundation, and water dumped at the top of a hillside lot runs toward the low corner of the basement or loads a retaining wall. A working gutter with downspouts that end well away from the house is the cheapest protection against that.

How many quotes should I get for new gutters?

Two or three is usually enough to see the range, as long as each one is itemized the same way. Compare the gauge, hanger type and spacing, downspout size and count, fascia pricing and haul-away rather than the bottom-line number. A quote that won't list those items is hard to compare at all.
