Preparing Your Garage Door for Hot Weather: Essential Tips

2024-01-10 7 min read West Roxbury Garage Doors Team

As temperatures rise, your garage door faces unique challenges that can affect its operation, appearance, and lifespan. Hot weather can cause expansion of metal components, degradation of weatherseals, and stress on the motor and springs. This guide will help you prepare your garage door for the summer months and prevent heat-related problems.

How Heat Affects Your Garage Door

Metal garage doors expand in hot weather, which can cause binding, misalignment, and increased stress on the opener motor. Dark-colored doors absorb more heat and can become extremely hot to the touch, potentially warping or causing paint to fade. The rubber weatherseals around your door can dry out and crack in sustained heat, compromising your garage's insulation and allowing pests to enter.

Springs are particularly affected by temperature changes. As metal heats up, it becomes more pliable, which can change the spring tension and affect how smoothly your door operates. This is why doors sometimes seem easier or harder to open at different times of day during summer.

Pre-Summer Maintenance Checklist

Inspect and lubricate all moving parts: Before summer heat sets in, apply silicone-based lubricant to the springs, hinges, rollers, and tracks. This helps components move smoothly despite thermal expansion. Avoid using WD-40 as your primary lubricant, it's a cleaner, not a long-term lubricant.

Check the weatherstripping: Examine the rubber seals around the door's edges and along the bottom. Look for cracks, gaps, or hardening. Replace any damaged weatherstripping before summer to maintain your garage's temperature and keep out pests and water.

Test the balance: Disconnect the opener and manually lift the door halfway. A properly balanced door should stay in place. If it falls or rises, the springs need adjustment. This is especially important before summer, as heat will further affect spring tension.

Clean and inspect the tracks: Remove any debris from the tracks and check for dents or misalignment. Smooth, clean tracks reduce stress on the motor and prevent binding when components expand in heat.

Protecting Your Door from Sun Damage

If your garage door faces south or west, it receives the most intense sun exposure. Consider these protective measures:

Apply UV-protective finish: For wood doors, apply a UV-resistant stain or sealant. For steel doors, high-quality exterior paint with UV inhibitors helps prevent fading and heat absorption.

Consider lighter colors: If you're replacing your door or repainting, lighter colors reflect more sunlight and stay cooler. This reduces expansion stress and helps maintain garage temperature.

Install insulation: Insulated garage doors maintain more stable internal temperatures, reducing stress on all components and making your garage more comfortable during summer months.

Summer Operation Tips

During hot weather, give your motor occasional breaks during heavy use. If you're moving items in and out of the garage repeatedly, pause for a few minutes between cycles to prevent overheating. Modern openers have thermal protection, but it's still good practice to avoid excessive continuous operation.

Keep your garage ventilated if possible. Extreme heat buildup in the garage puts additional stress on the door and opener. Screen vents or exhaust fans can help maintain reasonable temperatures.

Watch for signs of heat-related problems: increased noise during operation, sluggish movement, or the door seeming to stick at certain points. These often indicate components need adjustment or lubrication.

When to Call a Professional

If you notice significant changes in your door's operation as temperatures rise, it's time for a professional inspection. Issues like persistent sticking, unusual noises, or visible warping should be addressed promptly to prevent more serious damage.
