Your garage door is one of the first things people notice about your home, adding to its curb appeal while keeping your vehicles and belongings safe. However, one constant threat can affect its look and durability over time: the sun.
In Laramie, where the sun can be intense in the summer months, UV rays continuously target your garage door. This can cause fading, material damage, and even compromise its structural integrity. The good news is, with the right preventive care, you can protect your garage door from sun damage and ensure it stays looking great for years to come.
Understanding Sun Damage
When the sun shines on your garage door, it’s not just providing warmth and light—it’s also bombarding your door with constant ultraviolet (UV) radiation that can seriously damage its materials. UV rays are particularly sneaky because their effects build up over time, often going unnoticed until significant deterioration has already occurred.
Wooden garage doors are especially vulnerable to sun exposure. Prolonged UV rays can dry out the wood, causing fibers to weaken, crack, and split. Metal doors, like steel or aluminum, aren’t immune either. Sun exposure can cause the paint to fade, and in some cases, lead to warping—especially in areas where protective coatings have worn away. If your door features windows, the weatherstripping and seals around them are also at risk. Over time, UV rays can make these materials brittle, reducing their effectiveness.
If left unchecked, sun damage sets off a chain reaction. What begins as fading can escalate into serious material breakdown, decreased insulation efficiency, and even operational issues. Warping can cause parts to become misaligned, making your garage door harder to open and close. These issues not only affect your home’s appearance but can also compromise the basic functionality of your garage door.
What Materials Are Likely to be Affected by Sun Damage?
Different garage door materials respond to sun exposure in unique ways, so it's essential to understand these vulnerabilities in order to protect your investment.
Wooden doors, though naturally attractive, are especially sensitive to the sun's harsh effects. UV rays break down lignin, the natural compound that holds wood fibers together, causing the surface to gray and develop deep cracks. When the summer heat mixes with humidity, moisture can seep into these cracks, creating the perfect conditions for warping and rot. Even treated wood isn’t fully immune—it offers some protection but still requires regular maintenance to keep it safe from the sun’s damaging effects.

Vinyl garage doors face their own set of challenges when exposed to the sun. While they’re built for outdoor use, prolonged UV exposure can make the material brittle over time. It’s similar to how a plastic chair left outside eventually becomes fragile and prone to cracking. Over time, the sun can also cause significant color fading, turning a once-bright white door into an uneven, yellowed surface that detracts from your home’s appearance.
Fiberglass doors are generally durable but aren’t immune to UV damage. Continued exposure to sunlight can cause the material to yellow and become chalky. The protective gel coat that gives fiberglass its smooth, glossy finish gradually deteriorates, making the surface rougher and more prone to dirt buildup and visible wear.
Metal doors, including steel and aluminum, face their own battle with intense sunlight. The UV rays break down the paint’s chemical structure, leading to fading and chalking. Over time, the protective coating can wear away, exposing the metal underneath to moisture. This can lead to rust spots, particularly in areas where the door has been scratched or dented.

How to Prevent Sun Damage to Your Garage Door
Protecting your garage door from sun damage begins with choosing the right materials. Select UV-resistant options like steel with baked-on enamel coatings or composite wood that’s designed to handle intense sun exposure. These materials are specially crafted to resist fading and prevent structural damage, helping to keep your garage door in great shape for longer.

Regular maintenance is essential for protecting your garage door from sun damage. By establishing a simple routine of cleaning and inspecting your door, you can significantly extend its lifespan. For wooden doors, this means gently washing the surface to remove dirt and contaminants, then reapplying a high-quality stain or finish every few years to shield it from UV rays and moisture. Routine inspections also help catch early signs of wear, so you can address small issues before they turn into bigger problems.
Protective coatings are another valuable defense. UV-blocking paints and sealants for wood and metal doors create a protective barrier, keeping the sun’s rays from damaging the surface. These coatings preserve your door’s color and add an extra layer of defense against the elements, helping to keep it looking great longer.
You can also consider adding shade structures like awnings or pergolas to reduce direct sunlight exposure. These structures can help block the constant UV rays that contribute to fading and wear.
Strategically planting trees or shrubs near your garage door can provide natural shade and keep the door cooler. Just make sure the plants are placed at a safe distance to prevent root damage or moisture-related issues.
Ultimately, regular inspections are key. Watch for signs of sun damage, such as fading or cracks, and take action quickly. By staying proactive, you can maintain your garage door’s appearance and functionality for years.
