Signs you need new gutters

Gutters fail slowly. By the time water is pouring over the edge or pooling at your foundation, the damage has been building for months.

  1. Water spilling over the edges during rain instead of flowing to downspouts
  2. Gutters pulling away from the fascia board or sagging visibly
  3. Cracks, holes, or rust spots along the gutter channel
  4. Pooling water or erosion at your foundation after storms
  5. Paint peeling or staining on the fascia or soffit behind the gutters
  6. Ice dams forming at the gutter line during winter
  7. Mold or mildew on exterior walls below the roofline
  8. Gutters are more than 20 years old and patched multiple times

If any of these sound familiar, call (406) 313-3020.
We can usually diagnose in one visit.

Why Swagg Roofing
for gutters

Frequently Asked Questions

How much do new gutters cost in Montana? +
Gutter pricing depends on your roofline length, material choice, number of downspouts, and whether we are removing an old system. Most residential gutter installs fall between $1,500 and $4,000. You get a free written estimate with exact pricing before any work starts.
How long does gutter installation take? +
Most homes are completed in one day. Larger or multi-story homes may take a second day. We give you a specific timeline in your written estimate.
WWhat warranty do you offer on gutters? +
All gutter work comes with a written workmanship warranty covering installation, hangers, seals, and pitch. Materials carry their own manufacturer warranty on top of that.
What size gutters do I need? +
Most Montana homes do well with 5-inch seamless aluminum gutters. Homes with steep roofs, large roof areas, or heavy tree coverage may need 6-inch gutters with oversized downspouts to handle the water volume.
Are seamless gutters better than sectional? +
Yes. Seamless gutters have no joints along the run, which eliminates the most common failure point. Sectional gutters leak at every splice over time. We only install seamless systems.
Do you install gutter guards? +
Yes. We install debris screens and leaf guards on new and existing gutter systems. Guards reduce cleaning frequency and prevent clogs that cause overflow.
Can you replace gutters as part of a roof replacement? +
Absolutely. Bundling gutters with a roof project gives you a cleaner install, matched materials, and typically a lower combined price than doing them separately.
Do you offer financing for gutter projects? +
Yes. We offer $0 down financing options for qualified buyers. Ask your project manager for details during your estimate appointment.
What materials are available for gutters? +
We install seamless aluminum (most common, lightweight, rust-resistant) and steel (heavier duty, ideal for high-snow areas). Both come in multiple colors to match your home.
How do I know if my gutters can be repaired or need full replacement? +
If the damage is limited to one or two sections with isolated leaks or loose hangers, repair usually makes sense. If you see widespread rust, multiple sags, or the gutters are pulling away from the fascia in several areas, replacement is the better long-term investment.
