How to Winterize Your Roof and Gutters Before the First Snow
As the temperatures drop and snowstorms loom, it’s essential to prepare your roof and gutter system to withstand Denver’s harsh winter conditions. Proper winterization protects your home from ice dams, water intrusion, and expensive repairs — and it starts with a few smart steps.
Step 1: Clean Out Gutters and Downspouts
Leaves, pine needles, and debris in your gutters can block water flow and lead to ice dams. Backed-up water can freeze, causing gutters to crack or pull away from your roofline.
Pro Tip: Clear your gutters in late fall, and make sure downspouts direct water away from your foundation by at least 3 feet.
Step 2: Inspect and Secure Flashing
Flashing seals the edges of roof penetrations like chimneys, vents, and skylights. These areas are prone to leaks in freezing conditions.
Pro Tip: Have a roofer check and reseal flashing with roofing-grade caulk or replace damaged pieces as needed.
Step 3: Check Attic Insulation and Ventilation
Improper insulation can allow heat to escape into your attic, which melts snow on your roof. That meltwater then refreezes at the eaves, forming destructive ice dams.
Pro Tip: Add or replace attic insulation where needed and make sure your soffit and ridge vents are clear and functioning.
Step 4: Trim Overhanging Tree Branches
Heavy snow and ice can weigh down branches, causing them to snap and damage your roof or gutters.
Pro Tip: Trim branches to at least 6 feet away from your roof and power lines before snow season.
Step 5: Inspect Shingles and Sealants
Loose, cracked, or missing shingles leave your roof vulnerable to water intrusion when snow begins to melt.
Pro Tip: Look for damaged shingles and seal exposed nail heads to help keep water out.
Step 6: Install Ice and Water Shield (If Needed)
If you’re re-roofing or upgrading before winter, ask your roofer about ice and water shield underlayment — a self-sealing barrier that helps prevent leaks from ice dams.
