Gutter Installation & Replacement in the Twin Cities
Seamless aluminum gutters, properly pitched, with the owner on your job. Free inspection. MN Lic# BC809688.
Clogged, sagging, or improperly-pitched gutters don't just look bad — they direct water into your fascia, soffit, and foundation. Northern Forge installs seamless aluminum gutters that are cut on-site to exact lengths, properly sloped to your downspouts, and secured with hidden hangers that won't pull out in winter ice loads.
Seamless vs. Sectional Gutters
| Factor | Seamless (What We Install) | Sectional (Big Box Store) |
|---|---|---|
| Leak points | Only at corners and downspouts | Every 10–12 feet |
| Installation method | Cut on-site to exact length | Pre-cut sections, gluedtogether |
| Lifespan | 20–30 years | 10–15 years |
| Appearance | Clean, continuous profile | Visible seams and joints |
| Maintenance | Lower — fewer failure points | Higher — seams need resealing |
Northern Forge installs seamless gutters only. We don't do the sectional stuff from the hardware store.
5-Inch vs. 6-Inch Gutters
Standard K-Style
Right for most Twin Cities homes. Handles typical roof drainage without looking oversized. Lower cost. Works with standard downspouts.
Best for: Standard-pitch roofs, most residential homes
Oversized K-Style
Handles 40% more water volume. Worth it for steep roofs, large roof sections, or homes prone to overflow during heavy rain. Pairs with 3×4 downspouts.
Best for: Steep pitches, large homes, high-volume drainage areas
Gutter Guard Options
We'll give you an honest comparison — not a sales pitch for the most expensive option.
| Guard Type | How It Works | Effectiveness | Cost | Our Take |
|---|---|---|---|---|
| Micro-mesh (aluminum) | Fine mesh stops debris, water flows through | Excellent | $$$ | Best long-term option for MN |
| Reverse curve / surface tension | Water clings to curved surface, debris falls off | Good | $$$ | Works well, requires professional install |
| Perforated / screen | Screen lets water in, blocks large debris | Moderate | $$ | Fine seeds and pine needles still get through |
| Foam inserts | Foam in gutter, debris sits on top | Poor | $ | We don't install these — they clog and harbor mold |
What Proper Gutter Installation Looks Like
Most gutter problems come from installation shortcuts. Here's what we do on every job:
- Hidden hanger fasteners every 24 inches (not every 36–48 like cut-rate installers)
- Proper 1/4-inch per 10-foot pitch toward downspouts
- Drip edge behind gutter top for proper water transfer
- Downspout extensions directing water at least 6 feet from foundation
- Sealed mitered corners (not just crimped)
- Correct downspout sizing for gutter volume
- Final flush test before we leave
Bundle Your Gutter & Roof Replacement
If you're already replacing your roof, gutters are the natural companion project. We'll coordinate both so you're not dealing with two separate crews — and your new gutters will be matched to your new drip edge profile.

Most homes do fine with 5-inch gutters. If you have a steep or large-surface roof that dumps a lot of water during heavy rain, 6-inch gutters handle 40% more volume and are worth the upgrade. Luis will measure your roof surface area and recommend the right size at the free inspection.
Gutters don't cause or prevent ice dams — ice dams form above the gutter line from heat escaping through the roof deck. What gutters do is manage the meltwater once an ice dam forms. Proper attic ventilation is what prevents ice dams at the source.
20–30 years with proper installation and occasional cleaning. The fasteners and hangers usually fail before the gutter material itself — which is why we use hidden hangers rated for Minnesota's ice loads.
Possibly not on all sides. But in Minnesota, the freeze-thaw cycle means water that seems to drain away in fall can refreeze against your foundation in winter. Luis will assess your specific lot during the inspection and give you an honest answer — not a "you definitely need gutters everywhere" pitch.
Quality micro-mesh guards are worth it if you have trees overhanging your gutters and dread the twice-yearly cleaning. Cheap foam or screen inserts are not — they clog with small seeds and create more problems than they solve. We'll be straight with you about whether guards make sense for your situation.
Yes — hail and wind can damage gutters and downspouts, and insurance will often cover replacement alongside the roof. We document gutter damage as part of every storm inspection so nothing gets left off the claim.
