☀️⛰🌪 At high altitude, Colorado roofs take a beating. The sun is stronger, the hail hits harder, and the weather swings from blazing hot to freezing cold in a single day. That’s why more homeowners and contractors are turning to metal roofing over shingles.

Here are 3 reasons why:

1️⃣ UV Durability – At elevation, shingles dry out and crack quickly. Metal stands up to Colorado’s intense sun, season after season.
2️⃣ Hail Resistance – Colorado’s hailstorms are no joke. Metal resists impact far better, saving you from costly repairs.
3️⃣ Lifetime Value – Shingles need replacing again and again. Metal lasts 40–70 years, delivering real long-term savings.

💪 Built for altitude. Built to last. Flatiron Steel
