Gutter replacement and seamless gutter installation in Pittsburgh

Seamless gutters

Pittsburgh, PA winters are why seamless matters. A seamless gutter is made on site from a single coil of aluminum, so each run is one piece from corner to corner. Sectional gutter from a hardware store has a joint every 10 feet, and in a climate that freezes and thaws dozens of times a winter, every joint becomes a leak. A well-hung seamless system should still be tight in twenty years; the sectional system it replaces often starts weeping in eight. Residential seamless gutters are the standard choice for that reason, and the only real decisions are size, gauge and hangers.

Sizing for Pittsburgh

Rain here isn't as violent as the Gulf Coast, but it's steady and it comes with two things southern crews never think about: snow sliding off the roof and ice sitting in the trough for weeks. A good spec accounts for both.

• 5-inch gutters with 3x4 downspouts on most single-story and modest two-story homes. The larger downspout roughly doubles capacity for a few dollars more per drop.
• 6-inch gutters on large roofs, steep slate or metal roofs where snow comes off in a sheet, and any run collecting more than about 1,000 square feet.
• Hangers every 16–24 inches with screws into the rafter tails — closer spacing on the north side of the house where ice lingers. Avoid spike hangers.
• A second downspout on any run over 35 feet. One downspout on a 60-foot run is a classic reason a clean gutter overflows.

The math for your own roof is in how much roof drains into one downspout.

Aluminum gutters

Pittsburgh's road salt and wet sidewalks are the main reason aluminum beats steel here: it won't rust where a downspout meets the ground or where salt splashes. Ask for .032 gauge, heavier than the .027 some installers use, in one of the 25-plus baked-on colors most suppliers stock. Copper and galvanized steel are quoted separately for the homes where they belong — copper on a slate-roofed house in Fox Chapel or Sewickley, for instance, where it will outlast everyone reading this.

Replacement or new gutter installation

Pittsburgh, PA replacement work is mostly 1950s–70s aluminum in Ross Township, Bethel Park, Monroeville and Moon Township that has reached the end of its life. Local gutter installation in Pittsburgh should include, in writing:

• Tear-off and haul-away of the old gutters and downspouts
• A fascia check, with any rotted board replaced before the new gutter goes up (quoted per foot)
• New seamless gutter, corners, end caps and downspouts
• Downspout extensions or connections so water lands at least six feet from the foundation, or into a drain that has been tested and still works
• A water test when the work is done

Choosing a gutter installation company

Compare quotes on the same spec, not the same total. Ask each gutter installation company for the gauge, hanger type and spacing, downspout size and count, and whether fascia and haul-away are included. Look up the contractor's Pennsylvania home improvement registration with the Attorney General's office and ask for a certificate of insurance. Calls and estimate requests from this site go to an independent local contractor partner who quotes and performs the work; you are never obligated to hire.

Homes that never had gutters, or shouldn't get hung ones

Plenty of Pittsburgh homes have gutters on the front and nothing over the back porch or a side addition. Partial runs are fine; the wall that solves the problem is the one to do. What should never happen is aluminum hung on the face of a built-in box gutter to hide a failed lining. That's a box gutter job, and the two get confused often enough that it has its own guide.

What to check on the old system first

Before anyone quotes new gutters, it's worth knowing why the old ones failed, because the same cause will work on the new ones.

• Soft fascia under corners and downspouts means water has been behind the gutter for years. New gutter on rotten wood pulls loose in the first winter.
• Where the downspouts go. If one drops into a buried clay pipe, find out whether that pipe still drains before a new downspout is connected to it.
• The roof edge. Shingles or slate should overhang the gutter slightly, with drip edge behind it. If water has been running down the fascia, part of the fix belongs at the roof edge.
• Where the ice sat. Bent front lips and pulled hangers on one side of the house point to the eave that needs closer hanger spacing.

Common mistakes on new gutters

• Hanging a run level instead of pitched toward the downspout. A quarter inch every ten feet is the usual target.
• Reusing the old downspout positions without asking whether a long run needs a second one.
• Letting a downspout end at the wall because there was never an extension.
• Skipping the fascia check to keep the quote low.
• Adding guards to a gutter that was never sized for the roof.

Each of these is cheap to get right on install day and expensive to fix after the first winter.

Installation day

The installer arrives with the coil and the forming machine on the truck. Old gutters come down, fascia gets checked, then each run is measured and formed to the exact wall length. Corners are sealed, downspouts strapped every 8 feet, extensions set, and a hose run through everything. Most homes are done in a day. Hillside lots with a two-story drop on the downhill side, common across Pittsburgh, sometimes need staging and run into a second morning; ask whether the estimate allows for that.

Cost

Seamless aluminum installed is about $9–$15 per foot here. A single-story home with 140 feet and four downspouts is typically $1,400–$2,100; a two-story with 200 feet and six downspouts, $2,200–$3,200. The pricing page has the tables, and what the price per foot actually buys explains why three quotes on the same house can be $900 apart.
