New Colorado Fire Code: What It Means for Your Roof

Colorado's New Wildfire Resiliency Code:

What It Means for Your Roof Replacement

Starting July 1st, a new Colorado fire code could add thousands of dollars to your roof replacement project, and it might require upgrades to your siding, doors, windows, and fascia even if a new roof was all you planned for.

Here at Excel Roofing, we want you to understand exactly what the Colorado Wildfire Resiliency Code means for your home, why it exists, and how to prepare for it before you start collecting quotes. By the end of this article, you'll know whether your property is affected, what the code requires, what can trigger additional work, and how to avoid surprise costs.

For decades, homes in Colorado's foothill and mountain communities were built without specific wildfire protections. That has changed. The new code requires those protections, and the scope goes well beyond the roof.

Here is the official state website's interactive map:

What Is the Wildland-Urban Interface (WUI)?

The first step is finding out whether your property sits inside a wildfire hazard area. The Colorado State Forest Service has mapped the Wildland-Urban Interface, or WUI, an interactive tool that shows exactly which properties are affected. Check your address against the state's official WUI map. If your home falls inside one of the highlighted zones, the new code applies to you.

Understanding Your Fire Intensity Classification

If your property is in a WUI area, it also receives a fire intensity classification of Low, Moderate, or High. The state assigned these ratings using its 2022 Colorado Wildfire Risk Assessment, which weighs vegetative fuel, topography, and typical weather conditions for each area.

Classification	Color	What It Means
Low	Yellow	Minimal wildfire exposure based on fuel, topography, and weather patterns
Moderate	Orange	Elevated risk; additional protections likely required
High	Red	Greatest risk; most stringent protections apply

Your classification determines exactly what your home needs, and it's the first thing a qualified contractor should check before writing an estimate.

What the Code Requires: Class A Roofing

At minimum, any roof installed in a WUI area must carry a Class A fire rating, the highest fire-resistance classification for roofing materials. This isn't a new recommendation from us. Excel Roofing has been steering Colorado homeowners toward Class A materials for years because of how common wildfire exposure is across the Front Range and mountain communities.

What Could Trigger Additional Upgrades

Here's where homeowners are often caught off guard. When you pull a permit for a new roof in a WUI zone, inspectors now also look at:

• Eaves and soffits
• Fascia
• Exterior doors
• Windows

If a roof project triggers an inspection, the code official can require upgrades to any of these components, even if they weren't part of your original estimate. It can feel like a lot to take in, but with Colorado in an ongoing drought, these protections exist to keep homes and families safer when wildfire risk is highest.

When you schedule an inspection with us, we will:

• Siding
• Check your address against the official WUI map
• Identify your fire intensity classification
• Walk your property in person
• Explain exactly what the code requires, what a roof project might trigger, and what it will cost

No surprises. Just a clear picture before you commit to anything.

Frequently Asked Questions

How do I know if my property is in a Colorado WUI zone?

Check your address against the Colorado State Forest Service's interactive Wildland-Urban Interface map. If your property falls inside a highlighted zone, the Wildfire Resiliency Code applies to you.

What are the three fire intensity classifications?

Colorado properties in WUI zones are rated Low (yellow), Moderate (orange), or High (red), based on the state's 2022 Colorado Wildfire Risk Assessment of vegetative fuel, topography, and weather conditions.

Does the Wildfire Resiliency Code only affect my roof?

No. While every new roof in a WUI zone must carry a Class A fire rating, a roofing permit can also trigger inspection of eaves, soffits, fascia, exterior doors, windows, and siding.

Will I be required to upgrade my siding or windows just to replace my roof?

It depends on your fire intensity classification and what an inspector finds. Not every roof project triggers these upgrades, which is why a property-specific inspection matters before you get quotes.

What roofing material meets the new code?

Any roof installed in a WUI area must be rated Class A for fire performance, the highest available fire-resistance rating for roofing materials.

How can Excel Roofing help me prepare?

We'll check your address against the WUI map, identify your fire intensity classification, walk your property, and explain exactly what the code requires and what it will cost, before you commit to anything.
