If you’ve lived in Denver for more than a year, you already know the weather here doesn’t follow the calendar the way it does in other parts of the country. A 75-degree afternoon in March can be followed by a blizzard the next morning. Hail the size of golf balls can fall in late June. And by September, wildfire smoke from fires across the Front Range can push air quality into hazardous territory for days at a time.
Colorado has experienced 76 confirmed billion-dollar weather and climate disasters since 1980, with severe storms – including hail – accounting for more than half of all events, according to NOAA’s Colorado disaster summary. In the last five years alone, Colorado has averaged 4.4 billion-dollar disaster events per year, compared to 1.7 per year over the full historical record. The trend is clear: weather-related property damage in Colorado is becoming more frequent.
Many property damage problems can be reduced with regular, season-specific maintenance. This checklist walks Denver-area homeowners through what to do each season to reduce risk and catch potential problems before they become expensive emergencies.
Spring Checklist (March – May): Hail, Snow Melt, and Wind
Spring in Denver is the season of rapid change and high storm activity. It’s also the beginning of Colorado’s hail season – and the Colorado Climate Center’s historic weather records document major Denver hailstorms dating back to at least 1984, including the destructive 1990 Denver hailstorm.
Roof and Gutters
- Inspect your roof for winter damage: missing or cracked shingles, damaged flashing around chimneys or vents, and lifting at the ridge cap.
- Clean gutters and downspouts after winter. Debris accumulation causes water to back up under roofing material.
- Check downspout extensions to confirm they direct water at least four feet from your foundation.
- Make sure the ground around your foundation slopes away from the house – water that pools at the foundation can infiltrate the basement or crawl space. The EPA’s mold guidance specifically recommends ensuring the ground slopes away from the building foundation.
Windows and Doors
- Inspect caulking and weatherstripping around all windows and exterior doors. Winter temperature cycling often causes caulking to crack and shrink.
- Look for water staining inside window frames – a sign that water is getting past the seal.
Plumbing and Water Heater
- Remove any exterior faucet insulation you installed for winter.
- Test outdoor hose bibs before connecting hoses – sometimes freeze damage isn’t obvious until water pressure is applied.
- Flush your water heater (or have it serviced) to remove sediment. A water heater at the end of its life is a common source of flooding.
Know Your Hail Deductible
In Colorado, especially in the Denver metro and Eastern Plains, many homeowners’ insurance policies carry separate deductibles for roof and hail damage, according to the Credit Union of Colorado’s hail damage guide. Before hail season begins, pull out your declarations page and confirm what your deductible is. This affects whether filing a claim after a small hail event makes financial sense.
Summer Checklist (June – August): Storms, Flash Floods, and Moisture
Summer in Denver brings afternoon thunderstorms, localized flooding, and intense heat. July and August are peak flash flood months along the Front Range. The devastating September 2013 Colorado floods – which affected many parts of the state and caused over $2 billion in damage as recorded by NOAA – serve as a reminder that flood risk here is real and can develop rapidly.
Drainage and Grading
- Walk your property during or just after a heavy rain. Watch for:
- Water flowing toward the house rather than away from it
- Pooling near the foundation or in the window wells
- Saturated soil near the home for more than 24 hours after rain ends
- Clear any storm drains or culverts on your property of debris.
Basement and Crawl Space
- Test your sump pump. Pour a bucket of water into the sump pit to confirm it activates and discharges properly.
- Consider a battery backup for your sump pump. Power outages frequently accompany the same storms that trigger flooding.
- Check your crawl space for standing water or moisture on vapor barriers.
- Keep indoor humidity below 60% – ideally between 30% and 50% – as recommended by the EPA. Use a dehumidifier if needed.
HVAC System
- Replace your HVAC filter before peak cooling season. A clogged filter causes your system to work harder and can lead to condensate drain clogs – a frequent and underappreciated source of water damage.
- Check that your condensate drain line is clear and draining properly.
- Keep air conditioning drip pans clean and drain lines unobstructed, as the EPA recommends.
Appliances
- Check washing machine hoses for cracks, bulging, or wear. Washing machine supply line failures are one of the most common sources of indoor flooding.
- Inspect dishwasher supply lines and door seals.
- Clean your refrigerator’s ice maker water line connection – these small connections can fail silently.
Fall Checklist (September – November): Wildfire Smoke and Early Freeze Prep
Fall in Denver is a beautiful season – and increasingly, a concerning one for air quality. Wildfire activity across the Colorado Rockies and Front Range has intensified significantly in recent years. NOAA’s data shows 12 billion-dollar wildfire events affecting Colorado between 1980 and 2024, with wildfire activity accelerating sharply in the 2010s and 2020s.
Wildfire Smoke and Indoor Air Quality
When wildfire smoke pushes into the Denver metro area, outdoor air quality can shift from healthy to hazardous within hours. The EPA recommends creating a “clean room” as part of wildfire preparedness – a room where you can minimize smoke infiltration during severe events.
To prepare for fall smoke season:
- Identify a clean room – ideally a bedroom with an attached bathroom that can be sealed off from the rest of the house.
- Stock a MERV 13 or higher HVAC filter and be prepared to install it quickly during a smoke event. The EPA guidance recommends MERV 13 filters for central HVAC systems during wildfire smoke events.
- Have a portable air purifier on hand – one sized for the room you plan to use as a clean room.
- Check your HVAC system’s fresh-air intake and know how to set it to recirculate mode, which prevents drawing in outdoor smoke.
- Inspect and replace HVAC filters more frequently during active smoke seasons.
Note: Wildfire smoke is an air quality and health concern, not typically a property damage event requiring restoration. The Colorado Department of Public Health and Environment’s wildfire air quality guidance provides real-time AQI tracking and recommends staying indoors, running HEPA filtration, and avoiding strenuous activity when smoke reaches unhealthy levels. However, if smoke or ash infiltration is severe – such as after the Marshall Fire (December 2021) or similar events – smoke odor and fine particulate deposition inside a structure may require professional cleaning and restoration.
Freeze Preparation
- Disconnect and drain all garden hoses before the first hard freeze. Water left in hoses can back-freeze into the supply line.
- Locate and insulate any pipes in unheated spaces: garages, crawl spaces, exterior walls.
- Know where your main water shutoff valve is and confirm it works. In a pipe burst emergency, every second before you reach that valve means more water on the floor.
- Schedule a chimney inspection and cleaning before fireplace season begins. A blocked or cracked chimney is a fire hazard.
Roof Before Winter
- Clear leaves and debris from gutters and valleys in your roof – debris traps moisture and can cause ice dams in winter.
- Inspect flashing around any roof penetrations: chimneys, skylights, vents.
- Trim any tree branches that overhang the roof. Denver’s wet, heavy snowfall can cause branches to break and fall on roof surfaces.
Winter Checklist (December – February): Frozen Pipes, Ice Dams, and Storm Damage
Denver winters range from mild to brutal, sometimes within the same week. The Colorado Climate Center lists Denver’s Christmas Eve Blizzard of 1982 and a significant March 2003 blizzard as historic events – and modern Denver homeowners have experienced snowfall events, ice storms, and deep freezes that test every system in the house.
Pipe Freeze Prevention
Frozen pipes are one of the most disruptive and expensive winter emergencies a Denver homeowner can face. When water freezes inside a pipe, it expands with enough force to split copper, PEX, or galvanized steel – and when the pipe thaws, it can release hundreds of gallons before the leak is discovered.
Prevent frozen pipes by:
- Keeping your thermostat at no lower than 55°F even when the house is empty.
- Opening cabinet doors under kitchen and bathroom sinks on exterior walls to allow interior heat to reach supply lines.
- Letting faucets drip at the furthest point from your water main during extremely cold nights – a slow drip prevents pressure buildup.
- Insulating pipes in garage, crawl space, and attic spaces before cold weather arrives.
Ice Dams
Ice dams form when heat escapes from a warm attic, melts snow on the upper roof, and that meltwater refreezes at the colder eave. As ice builds up along the eave, it can backwater under shingles and cause significant interior ceiling and wall damage.
Prevent ice dams by:
- Ensuring your attic is well-insulated (typically R-49 to R-60 for Colorado) to reduce heat loss through the roof deck.
- Making sure attic ventilation is adequate and unobstructed.
- Removing heavy snow from the lower several feet of your roof after major snowfalls using a roof rake – without getting on the roof.
Heating System
- Replace your furnace filter at the start of the heating season and every 30 to 90 days depending on the filter type.
- Have your furnace professionally serviced before peak heating season. A failure at the coldest point of winter can create conditions for frozen pipes throughout the house.
- Test your carbon monoxide detectors – heating system problems are a leading cause of CO buildup.
Year-Round Practices
Some damage prevention measures aren’t seasonal – they’re simply good habits:
- Know your home’s main water shutoff location. In an emergency, you need to find it in seconds.
- Test smoke and carbon monoxide detectors monthly.
- Check under sinks periodically for slow drips or supply line weeping – these small leaks often go unnoticed until they cause significant damage.
- Keep a current home inventory with photos and receipts stored off-site or in the cloud. This is essential for insurance claims after any major damage event.
- Review your insurance coverage annually. Make sure your dwelling coverage limit reflects current replacement costs, not what you paid for the house years ago.
