# Preparing Your Garage Door for Hot Weather: Essential Tips
As temperatures rise during the summer months in New Hampshire, your garage door faces unique challenges that can affect its performance and longevity. The combination of heat, humidity, and increased use during warmer weather requires special attention to keep your garage door operating smoothly. Here's your comprehensive guide to hot weather garage door maintenance.
High temperatures impact various components of your garage door system in different ways:
Metal expansion, Metal tracks, springs, and hardware expand in heat, which can affect door alignment and operation. This expansion can cause the door to stick or bind in the tracks.
Lubricant breakdown, The lubricants that keep your garage door running smoothly can thin or evaporate in extreme heat, leading to increased friction and wear on moving parts.
Weather seal deterioration, Rubber and vinyl weather seals can crack, warp, or become brittle when exposed to prolonged heat and UV rays, compromising their ability to keep out the elements.
Opener motor stress, Garage door openers work harder in hot weather, especially if the garage itself becomes extremely hot. This increased workload can lead to premature motor failure.
Before the hottest days arrive, take these proactive steps to prepare your garage door:
Inspect and replace weather stripping, Check the rubber seal at the bottom of your door and the weather stripping around the frame. Look for cracks, gaps, or sections that no longer make full contact. Replace any damaged seals to maintain energy efficiency and keep pests out.
Lubricate all moving parts, Use a silicone-based or white lithium grease lubricant specifically designed for garage doors. Apply to: - Hinges, Rollers (if they have bearings) - Springs, Bearing plates, Lock mechanisms
Avoid using WD-40 as a lubricant, while great for cleaning, it's not a long-term lubricant and can actually attract dust and debris.
Check the balance, Disconnect the automatic 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 a job for professionals due to the high tension involved.
Clean the tracks, Wipe down the inside of the tracks with a damp cloth to remove dirt and debris. Don't lubricate the tracks themselves, as this can cause the door to slip.
If your garage faces south or west and receives direct sunlight, additional protection may be needed:
Consider a lighter color, Dark-colored garage doors absorb more heat, which can warp the door and stress components. If you're due for a new door, consider lighter colors that reflect heat.
Apply UV protectant, For wooden doors, apply a UV-resistant stain or sealant annually. For steel or aluminum doors, a quality car wax can help protect the finish.
Install insulation, An insulated garage door helps regulate interior temperature, reducing stress on the opener motor and making your garage more comfortable. Insulation also improves energy efficiency if your garage is attached to your home.
A cooler garage means less stress on your garage door system:
Improve ventilation, Consider adding vents or a small exhaust fan to reduce heat buildup. Passive roof vents or gable vents can make a significant difference.
Use a garage door screen, A retractable garage door screen allows air flow while keeping bugs out, perfect for summer evening projects.
Park hot cars outside briefly, Let your car cool down for a few minutes before parking in the garage to reduce heat transfer.
Watch for these warning signs during hot weather:
- Door moves slowly or unevenly, Unusual grinding or squeaking noises, Opener motor overheating or shutting off, Visible warping or gaps in the door panels, Weather seal no longer seals properly
If you notice any of these issues, don't wait, addressing small problems early prevents major repairs later.
