Hail and sun damage to a garage door in Colorado

The Front Range sits in hail alley and gets intense high-altitude sun, so this is a real question here, not a rare one. Here is how to read the damage.

What Colorado hail does to a garage door

Hail hits a garage door flat on its largest, most exposed face, so a single storm can mark the whole door at once. What it does depends on the door:

• Hollow single-layer steel dents easily, often across every panel, because there is no backing behind the skin.
• Insulated steel resists hail far better, since the foam core stiffens each panel and absorbs the impact.
• Aluminum and glass can crack or shatter under large stones.
• Wood may dent or gouge and then trap moisture in the broken finish.

Most hail leaves shallow dimples that are purely cosmetic. The concern is the deeper strike that creases a panel, cracks the finish down to bare metal, or knocks a section out of alignment so it catches the rollers.

What sun and UV do over time

Sun damage is slower but just as real at altitude. Thin mountain air lets more ultraviolet light through, and with roughly 300 sunny days a year a south or west facing door takes a beating:

• Fading and chalking. Paint loses color and develops a dull, powdery surface, worst on darker colors that absorb more heat.
• Warping. Lightweight or hollow panels can bow as they heat and cool through big daily swings.
• Brittle seals and trim. Rubber and plastic dry out, stiffen, and crack, which then lets in drafts and water.

A quality baked-on finish and a lighter color slow all of this down, which is part of choosing the best door for Colorado weather in the first place.

Cosmetic versus structural: how to tell

Before you decide on a fix, sort the damage into one of two buckets:

• Cosmetic: shallow dimples, surface fading, minor scuffs. The door still opens, closes, and balances normally. You can live with it or address it for looks.
• Structural: deep dents or creases, cracked or split panels, bent tracks or rollers, a door that now sticks, sags, or runs crooked. This affects how the door works and should be repaired.

A quick test: disconnect the opener and lift the door by hand. If it still runs smoothly and holds its position halfway, the damage is likely cosmetic. If it drags, catches, or feels off balance, something structural moved.

Repair one panel, or replace the door?

Once you know the damage type, the decision usually falls one of three ways:

• Repair or leave cosmetic damage. Shallow dimples on an otherwise healthy door rarely justify a replacement.
• Replace a single panel when one section took the hit but the rest of the door, the springs, and the opener are in good shape and the panel style is still made. See whether you can replace just one garage door panel for your model.
• Replace the whole door when several panels are creased, the door is already aging, or matching panels are discontinued. At that point a new insulated door often costs less than chasing repairs and gives you a hail-resistant upgrade.

If a major storm hit your area, it is also worth checking whether your homeowner's insurance covers storm damage to the door before you pay out of pocket.

We inspect hail and sun damage across Denver and the Front Range, tell you honestly whether it is cosmetic or structural, and quote a flat rate for a single-panel fix or a full replacement. We serve Denver and the nearby suburbs with free estimates. After a big storm, a quick inspection is the cheapest way to know where you stand.

Most garage door hail damage in Colorado is skin deep, but the deep strike that bends a panel or throws the door off balance is the one worth fixing before it wears the opener and the springs.
