Storm Damage Checklist for Green Bay Gutters
After a storm moves through, a gutter system can end up with damage that isn't always obvious from the ground. This is a general checklist of what to look for — it's informational only, meant to help spot signs of damage, not a guide to what any of it means for a claim or what steps to take with an insurer.
Dents and Impact Marks
Hail and wind-driven debris can leave visible dents along the length of a gutter, most often on the section facing the direction the storm came from. Dents can range from small, shallow marks to larger deformities that visibly change the shape of the channel.
What to look for: Small circular dents spaced somewhat evenly along a run often indicate hail impact. Larger, irregular dents or gouges are more consistent with debris — a branch, or material carried by wind — striking the gutter directly.
Sagging Sections
A gutter run that's sagging or pulling away from a level line, rather than running straight, can result from added weight during a storm — waterlogged debris, ice, or a branch that landed and stayed — or from a fastener that gave way under stress.
What to look for: A visible dip or curve in an otherwise straight gutter run, or a section that looks like it's pulling slightly away from the fascia board behind it, both point to a sagging or loosening section.
Detached or Separated Sections
In more severe wind events, a section of gutter can partially or fully separate from the fascia, or come apart at a joint connecting two sections.
What to look for: A gutter section hanging at an angle, swinging loose, or missing entirely from part of a roofline is the clearest sign of this. Less obvious signs include a joint that's visibly gapped open where two sections used to sit flush.
Granule Buildup From Roof Damage
Loose granules from asphalt shingles collecting in unusually high amounts inside a gutter channel after a storm can be a sign that the roof itself — not just the gutter — took some impact.
What to look for: A noticeably heavy, gritty buildup of dark granules in the gutter, beyond what normal shingle wear would produce over the same period, especially right after a hailstorm or high-wind event.
Downspout Damage
Downspouts can take their own damage separately from the gutter run itself — a section knocked loose, crimped by falling debris, or disconnected at a joint during high wind.
What to look for: A downspout that's visibly bent, hanging at an odd angle, or separated from the wall bracket it's normally secured to.
Timing the Check
Looking things over reasonably soon after a storm — within the following few days, weather permitting — tends to produce a clearer picture than waiting weeks. Loose debris settles, wind and rain can further shift an already-loosened section, and small details like fresh granule buildup are easier to distinguish from ordinary seasonal wear when the check happens close to the event itself.
Ground-Level vs. Close Inspection
A ground-level walk around the house catches the more obvious signs — a visibly sagging run, a downspout hanging loose, a gutter section clearly out of alignment. What it tends to miss are smaller details: shallow dents that only show up at the right angle, a joint that's loosened but hasn't fully separated, or granule buildup that's only visible looking down into the channel itself. Both levels of looking have a place — the ground-level walk is a reasonable first pass, and a closer look fills in what that pass can't catch from a distance.
A Simple Walkthrough After a Storm
- Walk the perimeter of the house and look at each gutter run from the ground, checking for dents, sagging, or obvious gaps.
- Look specifically at downspouts for bends, separations, or loose brackets.
- Note any unusually heavy granule buildup inside the gutter where it's visible.
- Take photos of anything that looks different from before the storm, dated with when they were taken.
- Keep a record of what was observed and when, in case it's useful for later reference.
What This Checklist Doesn't Cover
This list is meant to help identify visible signs of storm-related gutter damage — it isn't a guide to what those signs mean for repair needs, what any of it costs, or what to do about a homeowners insurance policy. For general, informational background on how storm damage and insurance coverage relate, see gutter damage and insurance claims: what to know. Neither article is a substitute for a homeowner's own policy or their insurer's guidance.
The Bottom Line
Dents, sagging, detached sections, and granule buildup are the main visible signs that a gutter system took damage in a storm. Spotting them early, and documenting what's found, is a reasonable first step regardless of what happens next. A gutter inspection & damage assessment can take a closer, more thorough look at a system after a storm than a ground-level walkaround allows.
