Steel is the strength play: galvanized and Galvalume gutters shrug off the ladder dings, hail, and snow loads that crush aluminum, which is why they're standard on commercial buildings and favored in hail alley and snow country. Free referral to a licensed local pro — one call, no obligation.
Steel is the strength play: galvanized and Galvalume gutters shrug off the ladder dings, hail, and snow loads that crush aluminum, which is why they're standard on commercial buildings and favored in hail alley and snow country. The trade is corrosion — zinc coatings sacrifice themselves over decades, and once red rust appears at scratches and cut edges the countdown starts. Galvalume (aluminum-zinc alloy coating) roughly doubles galvanized life.
These are the specific failure modes licensed installers see most on this work.
Rust-through beginning at cut ends, scratches, and fastener penetrations.
Seam corrosion in sectional systems where water sits in the joint.
Weight demanding stout fascia and close hanger spacing — sag pulls fasteners in weak wood.

We connect you with a licensed local gutter professional who covers your area.
The pro inspects and quotes the work. No obligation, and the referral costs you nothing.
Your local pro completes the job — installation, repair, or maintenance.
Hail-prone regions, heavy-snow rooflines, commercial buildings, and anywhere mechanical abuse is likely (ladders, sports, low rooflines). Steel takes impacts that permanently crease aluminum.
Both are steel with sacrificial metallic coatings: galvanized is pure zinc, Galvalume adds aluminum to the alloy and roughly doubles corrosion life. If you're paying for steel install labor, Galvalume is usually worth the small material premium.
Eventually, at the vulnerable points: cut edges, scratches, screw penetrations, and standing-water lines. Quality installs seal cut ends and use matching screws; annual touch-up of scratches extends life significantly.
It's their strongest case. Aluminum hail damage is cosmetic-to-functional creasing that insurance fights over; steel typically takes the same storm without a mark.
Yes — seamless machines run steel coil, though fewer crews carry it than aluminum. Expect a specialty contractor and modestly higher labor; the seam elimination matters even more for steel because seams are where it rusts.
Roughly triple aluminum's weight before water and debris load. Sound fascia and hangers every 18–24 inches are non-negotiable; a pro will probe the wood before hanging steel.
Between aluminum and copper. The licensed installer prices by gauge, coating, and footage — GutterLinker's referral is free.
Keep them clean (standing water is the enemy), touch up scratches with zinc-rich primer, rinse coastal salt seasonally, and recoat the interior trough if finish thins — a maintained Galvalume system can reach 40 years.
