# Preparing Your Garage Door for Hot Weather: Essential Tips

As temperatures rise in New Hampshire, your garage door faces unique challenges. Heat can affect metal components, lubrication, and overall performance. Here's how to keep your garage door operating smoothly all summer long.

How Heat Affects Your Garage Door

Metal Expansion

High temperatures cause metal tracks, springs, and hardware to expand. This can lead to:

- Binding or sticking during operation - Increased wear on moving parts - Slight changes in door alignment

Lubrication Issues

Heat can cause lubricants to thin out or evaporate faster than normal, leading to:

- Increased friction and noise - Faster wear on rollers and hinges - Potential for metal-on-metal contact

Weatherstripping Degradation

Rubber weatherstripping can deteriorate faster in heat:

- Becomes brittle and cracks - Loses its seal, allowing hot air and pests inside - May need replacement more frequently

Summer Maintenance Checklist

1. Inspect and Lubricate

Apply a silicone-based lubricant to:

- Rollers and hinges - Tracks (lightly) - Springs - Pivot points

Avoid petroleum-based products that can attract dust and dirt.

2. Check Weatherstripping

Examine the weatherstrip along:

- Bottom of the door - Sides and top - Between door panels

Replace any that shows cracking, gaps, or compression damage.

3. Test the Balance

An unbalanced door works harder:

1. Disconnect the opener 2. Manually lift the door halfway 3. Let go – it should stay in place 4. If it moves up or down, call for professional adjustment

4. Inspect Hardware

Look for:

- Loose bolts or screws - Worn rollers - Damaged cables - Rust or corrosion

5. Clean Tracks and Sensors

- Wipe tracks with a clean cloth - Remove debris from the garage floor - Clean safety sensor lenses

Energy Efficiency Tips

Keep your garage cooler and reduce energy costs:

Insulated Doors: If you don't have one, consider upgrading to an insulated garage door. It keeps the garage cooler and reduces heat transfer to your home.

Weatherseal: Ensure all weatherstripping is in good condition to prevent hot air infiltration.

Ventilation: Consider adding garage ventilation to reduce heat buildup.

Light Colors: If replacing your door, lighter colors reflect more heat.
