A Stronger Roof Built to Withstand Severe Weather in Colorado
Colorado homeowners are no strangers to hailstorms, high winds, heavy snow, and rapid temperature swings. With these weather extremes becoming more frequent and costly, many property owners are asking: What is a fortified roofing system, and is it worth it?
A FORTIFIED™ roofing system is a construction and re-roofing standard developed by the Insurance Institute for Business & Home Safety (IBHS). It is designed to strengthen homes against severe weather by going beyond standard building code requirements. The program is based on decades of laboratory and field research into how roofs fail during wind, hail, and rain events.
What Makes a Roofing System “Fortified”?
A fortified roofing system is not just a brand of shingles. It is a set of specific installation methods and performance upgrades that work together to create a more resilient roof structure.
According to IBHS, the FORTIFIED Roof™ designation focuses on strengthening the most vulnerable parts of a home; the roof deck, edges, and attachment systems. Key elements include:
1. Sealed Roof Deck
The seams of the roof deck are sealed to create a secondary water barrier. If shingles are blown off during a storm, the sealed deck helps prevent rain from entering the home.
2. Enhanced Roof Deck Attachment
Stronger fasteners (such as ring-shank nails) are installed in specific patterns to improve resistance to wind uplift. This reduces the likelihood of the roof being torn off during high-wind events.
3. Reinforced Roof Edges
Roof edges are particularly vulnerable during storms. Fortified systems require enhanced drip edges and secure edge detailing to reduce the chance of wind peeling materials back.
4. Impact-Resistant Roofing Materials
Many fortified roofs incorporate materials that meet impact resistance standards to better withstand hail. This is especially relevant in Colorado, which consistently ranks among the top states for hail insurance claims.
5. Independent Verification
A third-party evaluator verifies that all fortified requirements have been met before the roof can receive an official FORTIFIED designation. This ensures accountability and compliance with the standard.
Why Fortified Roofing Matters in Colorado
Colorado’s Front Range experiences:
- Frequent hailstorms capable of damaging standard asphalt shingles
- High wind events along the I-25 corridor and in foothill communities
- Freeze-thaw cycles that stress roofing materials
- Heavy snow loads in certain areas
The National Weather Service and NOAA report Colorado as one of the most hail-prone states in the country, contributing to billions in insured losses annually.
A fortified roofing system is specifically designed to reduce the types of failures that occur during these events, particularly wind uplift and water intrusion after shingle damage.
How Fortified Roofing Differs From Standard Building Code
Traditional building codes establish minimum requirements for safety and construction. FORTIFIED standards go further by:
- Requiring stronger attachment methods
- Adding secondary water barriers
- Mandating specific inspection protocols
- Focusing on real-world storm performance testing
IBHS research facilities simulate hurricane-force winds, wind-driven rain, and hail impacts to evaluate roof performance. The FORTIFIED program is built from those findings.
Potential Benefits of a Fortified Roofing System
While every home is different, fortified roofs may offer:
- Reduced risk of storm-related roof failure
- Lower likelihood of interior water damage
- Increased durability and lifespan
- Potential eligibility for insurance discounts (varies by insurer and state - discounts not guaranteed)
Homeowners should consult their insurance provider to determine whether premium incentives apply in Colorado.
Is a Fortified Roof Right for Your Home?
A fortified roofing system is particularly beneficial in regions exposed to severe weather patterns making it highly relevant in Colorado. It is most commonly installed during full roof replacements rather than minor repairs, as the system requires access to the roof deck.
If you are evaluating a new roof installation, understanding the difference between minimum code compliance and fortified construction can help you make a more informed decision about long-term protection and resilience.For more information about Fortified Roofing, contact Select Roofing Company today.
