Flagstaff Spring Melt Checklist
Roughly 90 inches of snow has to go somewhere — here’s what to check as it does.
Most of Flagstaff’s snow falls in January and February, and the melt plays out gradually from February through May, with the city typically snow-free by the time May arrives. That stretch is when every weak point in your grading, gutters, and roof edge gets tested at once.

- Snow-free by May, typically

The checklist
Check three places as the snow goes
The crawl space, for water finding its way in through grading or downspouts. The gutters, for ice and debris still blocking proper drainage. The roof edge, for leftover ice dams that formed over winter and are only now letting go. All three get worse the longer the melt runs unchecked.
This is where winter’s leftovers show up
An ice dam that formed in January doesn’t finish doing damage until it melts in March or April — the same goes for grading issues and gutter problems that were frozen solid all winter and only become obvious once the water starts actually flowing again.

Water in the crawl space
If it shows up every melt season, that’s a grading or downspout issue, not something to just wait out.
See what it means →Gutters backing up as it melts
Ice and debris left over from winter can still dam a gutter well into spring, right as the heaviest melt is running through it.
See why gutters overflow →Ice still sitting at the roof edge
A late-season ice dam can keep backing water up under the shingles right through the final weeks of melt.

When does the spring melt actually happen in Flagstaff?
It’s gradual, running from around February through May, with the city typically snow-free by the time May arrives — not a single sudden event.
Why does an ice dam from January matter in spring?
Because it doesn’t finish causing damage until it actually melts — an ice dam that sat frozen solid all winter can still be forcing water under shingles well into March or April as it lets go.
Is some water in the crawl space during melt season normal?
A small amount of dampness can happen, but standing water or water that shows up every single melt season points to a grading or downspout problem worth fixing.
Should I check my gutters again even if I cleaned them in fall?
Yes — winter can leave ice and fresh debris behind even in a gutter that was clean in September, and spring melt is exactly when that backup becomes a problem.
What’s the single most important thing to check during spring melt?
The roof edge and gutters together — that’s where leftover winter ice does the most damage as it finally melts and has to go somewhere.
