The Flagstaff Home Maintenance Calendar
What to do, and by when, so the season doesn’t catch your house off guard.
The first fall frost lands around September 19 on average here, monsoon runs June 15 to September 30, and most of the roughly 90 inches of snow we get falls in January and February before melting out by May. None of that is random — it’s a real calendar, and this page is the five real windows worth planning around.

The five windows worth planning around
Late summer: Winter Prep
Before the first frost hits around September 19, gutters, pipes, weatherstripping, and the swamp cooler all need attention.

Before the rain starts June 15, gutters, drainage, and anything that could blow around need a check.

Landlords and property managers near campus work on an academic calendar, not just a seasonal one.

Roughly 90 inches of snow has to go somewhere once it starts melting — here’s what to check as it does.

Closing up for winter and opening back up in spring are two halves of the same job, done right.

Miss the window, pay more later
A gutter cleaned in August is a $150 job. The same gutter, ice-dammed and overflowing into a ceiling in January, is a very different bill. Most of what’s on this calendar is cheap prevention done at the right time, or an expensive repair done at the wrong one.
Flagstaff runs on a different clock
A fall-checklist article written for Phoenix doesn’t account for a September frost date or a 90-inch snow year. These five windows are built around what actually happens here, not a generic seasonal template.
FAQ
When should I start winter prep in Flagstaff?
Aim to have it done before the average first fall frost, around September 19 — waiting until the first cold snap actually hits means doing it in a rush, or after something’s already frozen.
Is monsoon season really worth prepping for separately from winter?
Yes — it’s a completely different kind of weather (short, hard, wind-driven rain from June 15 to September 30) that tests different parts of a house than winter cold does.
Does this apply if I only visit my Flagstaff property occasionally?
It applies even more — a second home or vacation property left unattended through a seasonal transition is exactly where small issues turn into big ones before anyone notices.
How far in advance should I book seasonal work?
As early in each window as you can — everyone else is calling at the same time once the weather actually turns, and booking deadlines tighten fast in the weeks right before each season starts.
Does this calendar get updated?
Yes, it’s republished each year as conditions and timing are rechecked, not left to go stale.
