Your garage door is a key feature of your home, not only enhancing its curb appeal but also providing security for your vehicles and belongings. However, one constant threat that can impact its appearance and longevity over time is the sun.
In Minnesota, where sunny days are a common occurrence, UV rays can take a toll on your garage door. Prolonged exposure to the sun can lead to fading, material degradation, and even weaken the structural integrity of your door. The good news is that with the right preventive care, you can protect your garage door from the damaging effects of the sun and keep it 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 harmful ultraviolet (UV) radiation that can gradually damage its materials. UV rays work silently over time, often causing noticeable damage long after the effects have started to build up.
Wooden garage doors are particularly vulnerable to prolonged sun exposure. UV rays can dry out the wood, weakening the fibers and causing cracks and splits. Metal doors, like steel or aluminum, aren't immune either. Continuous sun exposure can lead to fading paint and, in some cases, warping—especially in areas where protective coatings have worn off. If your garage door features windows, the weatherstripping and seals around them are also at risk. UV rays can make these materials brittle, which reduces their ability to protect your home.
If left unchecked, the damage caused by the sun can trigger a chain reaction. What starts as fading can evolve into serious material breakdown, reduced insulation efficiency, and even operational problems. Warping can lead to misalignment, making your garage door more difficult to open and close. Not only will these issues detract from your home’s appearance, but they can also compromise the functionality of your garage door.
What Materials Are Likely to be Affected by Sun Damage?
Different garage door materials react to sun exposure in unique ways, so it’s important to understand these vulnerabilities to protect your investment.
Wooden doors, while naturally beautiful, are particularly sensitive to the harsh effects of the sun. UV rays break down lignin, the natural compound that holds wood fibers together, causing the surface to gray and develop deep cracks. When summer heat combines with humidity, moisture can seep into these cracks, creating ideal conditions for warping and rot. Even treated wood offers some protection but still requires regular maintenance to safeguard it from the damaging effects of the sun.
Vinyl garage doors come with their own set of challenges when exposed to the sun. While they’re designed for outdoor use, prolonged UV exposure can make the material brittle over time. Think of it like a plastic chair left outside—it becomes fragile and more 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 overall appearance.
Fiberglass doors are known for their durability, but they’re not immune to UV damage. Continuous sunlight exposure can cause the material to yellow and become chalky. The protective gel coat that gives fiberglass its smooth, glossy finish slowly deteriorates, leaving the surface rougher and more susceptible to dirt buildup and visible wear.
Metal doors, such as steel and aluminum, also face the harsh effects of sunlight. UV rays break down the paint’s chemical structure, causing fading and chalking. Over time, the protective coating wears away, exposing the metal underneath to moisture, which can lead to rust spots—especially in areas that have been scratched or dented.

How to Prevent Sun Damage to Your Garage Door
Protecting your garage door from sun damage starts with choosing the right materials. Opt for UV-resistant options such as steel with baked-on enamel coatings or composite wood that’s designed to withstand intense sun exposure. These materials are specifically engineered to resist fading and prevent structural damage, ensuring your garage door remains in great condition for a longer period.
At McLeod County Garage Doors, we’re here to guide you in selecting the best materials for your home, helping to ensure that your garage door stays protected from the harsh sun and continues to look its best for years to come.
Regular maintenance is crucial 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 involves gently washing the surface to remove dirt and contaminants, and reapplying a high-quality stain or finish every few years to shield it from UV rays and moisture. Routine inspections also allow you to catch early signs of wear, so you can address small issues before they escalate into larger problems.
Protective coatings are another effective defense. UV-blocking paints and sealants for wood and metal doors create a protective barrier that helps prevent the sun's rays from causing damage. These coatings preserve your door’s color and provide an added layer of protection against the elements, ensuring it stays looking great for longer.
You can also consider adding shade structures like awnings or pergolas to reduce direct sunlight exposure. These structures can help block constant UV rays, which contribute to fading and wear over time.
Strategically planting trees or shrubs near your garage door can provide natural shade and help keep it cooler. Just be sure to place them at a safe distance to prevent any potential damage from roots or moisture-related issues.
Ultimately, regular inspections are essential. Watch for signs of sun damage, such as fading or cracks, and take action quickly. By staying proactive, you can maintain both the appearance and functionality of your garage door for years to come.
