Top Gutter Contractors in Des Moines
Our unbiased ranking of the best gutter contractors serving the Des Moines metro. Know what vetted installation quality looks like before you let anyone on your roof.
In Des Moines, the barrier to entry for calling yourself a “gutter contractor” is almost nothing. A truck, a ladder, and a beat-up roll former are about all it takes to hang a sign. The result? A market flooded with seasonal operators who vanish when the warranty comes due, leaving homeowners with sagging, leaking systems and no recourse. This guide cuts through the noise with non-negotiable standards and honest contractor intelligence built from over 10,000 local installations in the Central Iowa market.
The DSM Contractor Vetting Framework
Before looking at any individual company, every legitimate gutter contractor operating in the Des Moines metro must clear the following baseline requirements. If they fail even one of these, walk away.
| Vetting Criterion | Why It Matters in Iowa | How to Verify |
|---|---|---|
| Iowa Contractor License | Protects you legally; unlicensed work voids homeowner’s insurance claims | Iowa Division of Labor online lookup |
| Liability + Workers’ Comp | If an uninsured worker falls off your roof, you are liable | Request certificates of insurance; call the carrier to verify active status |
| On-site Roll Former | Seamless gutters require fabrication at your home; pre-cut sections = more seams = more leak points | Ask directly: “Do you fabricate seamless gutters on-site?” |
| .027 or .032 Gauge Aluminum | Iowa ice loads demand structural-grade material; .020 gauge bends under snow pack | Ask for the material spec sheet before signing anything |
| Hidden Screw Bracket System | Spike-and-ferrule installation fails in 3–7 years in freeze/thaw climates | Inspect their sample installation or ask for a photo of their bracket |
Tier 1 — Full-Service, Year-Round Operators
These contractors maintain permanent crews, carry proper insurance, and can handle everything from a simple 5-inch K-style installation on a ranch home to a complex 6-inch system with custom miters on a multi-peak acreage property. They will still be in business next year when your warranty matters.

The Red Flags: How Bad Contractors Win Bids in DSM
Storm-chaser gutter crews follow the same playbook as roofing fraudsters: they surge into the Des Moines market after a major weather event, offer prices 30–40% below legitimate operators, and disappear before the first winter cycle exposes their work. Here is exactly what they do and how to spot it.
Long aluminum nails driven through the face of the gutter into the fascia. In Iowa’s freeze/thaw climate, they pull out within 3–7 years, causing the gutter to lean, sag, and eventually detach entirely.
Sections joined with pop-rivets and caulk. Every joint is a future leak point. Iowa’s temperature swings cause the metal to expand and contract, eventually cracking the caulk and allowing water intrusion into the fascia and soffit.
Installing 2x3” downspouts on a 6-inch gutter is a volume mismatch that guarantees overflow during a typical Iowa summer storm. The chokepoint causes water to back up, overflow the front of the gutter, and saturate the foundation below.
Material warranties cover the aluminum — they do not cover improper pitch, sagging, or fastener failure. If a contractor won’t put a labor warranty of at least 2 years in writing, their confidence in their own work should tell you everything.
The 3 Questions to Ask Before Signing Any Gutter Contract
Before committing to any contractor in the Des Moines area, ask these three questions directly. How they respond will tell you more than any review platform.
- 1. “What gauge aluminum do you use, and will you put that in the contract?”
Any legitimate operator knows their gauge spec by reflex. Hesitation or a vague “standard grade” answer means you’re getting the cheapest material available.
- 2. “Do you fabricate the gutters on-site with your own roll former, or do you bring pre-cut sections?”
On-site fabrication is the single clearest signal of a full-service contractor. It cannot be faked.
- 3. “Can I see a copy of your workers’ compensation insurance certificate, and can I call the carrier to verify it’s active?”
Fraudulent or lapsed certificates are common among low-bid operators. Calling the carrier takes two minutes and can save you a $50,000+ liability lawsuit.
Quick Answer
The best gutter contractors in Des Moines operate year-round permanent crews, fabricate seamless gutters on-site with their own roll formers, use .027 or .032 gauge aluminum minimum, and install with hidden screw bracket systems — not spike-and-ferrule fasteners. Always verify their Iowa contractor license and call their insurance carrier to confirm active workers’ comp coverage before signing.
