Rolling shutters are fantastic additions to homes and businesses because they provide security, insulation, and light control. However, like any mechanical system, they are subject to wear and tear over time. A common issue many people face is damage to the slats, which are the horizontal segments that make up the rolling surface. If you’re unsure how to handle this, don’t worry—we’ve got you covered. This guide is packed with tips for repairing damaged slats in rolling shutters so that they stay functional and look as good as new.

Learn how to assess damage to rolling security shutters, what tools you’ll need for repairs, and how to prevent future problems. Plus, we’ll help you determine the best time to step back and call in the experts.

Understanding Rolling Shutter Slats

Types of Slats and Their Materials

Aluminum is the standard material for rolling shutter slats due to its lightweight, rust-resistant, and durability. Still, rolling shutter slats vary in design and construction, depending on their intended use:

• Single-wall extruded aluminum (Series 560/561/562) is strong and ideal for areas that demand durability. The aluminum slats are available with small or large perforations as well as a solid design.
• Double-wall extruded aluminum (Series 450) provides extra strength for commercial or heavy-duty applications.
• Foam-filled aluminum (Series 400/500) is lightweight and provides excellent insulation.
• Resin-filled aluminum (Series 440/540) provides insulation and superior protection from break-ins and weather.

Common Causes of Slat Damage

While DefendaGuard shutters can stand up to weather, extreme conditions may cause damage. Heavy rain, storms, or extreme temperatures can weaken or warp the slats over time. In addition, accidental bumps or strikes caused by flying debris during a storm or a vehicle hitting the shutter can dent or crack the slats.

Over time, daily use can cause minor damage that builds up, such as misalignment or small cracks. Understanding these details can help you diagnose, treat, and prevent slat damage more effectively.

Assessing the Damage

Before beginning repairs, it’s crucial to inspect the shutters and evaluate the extent of the damage. Follow these steps:

Inspect the Entire Shutter

Roll it up and down a few times to pinpoint the location of the damaged slats. Look for dents, tears, bends, or cracks.

Test the Movement

If the shutter doesn’t roll up smoothly or feels stuck, this could indicate damage affecting more than one slat, the guide rails, or the internal mechanism. Check the alignment of the slats, as well.

Review the Warranty

Some rolling shutters come with warranties that can be voided if you attempt unauthorized repairs. Always check your warranty documentation before proceeding with a DIY fix. This assessment will also help you determine whether you can fix the damage yourself or if it’s time to call a professional.

Tools and Materials You’ll Need

Repairing slats can be straightforward if you have the right tools and materials on hand. Here’s what you’ll need for the job:

• You’ll need either a flathead or Philips screwdriver, depending on the shutter model. This will help you loosen and remove screws from the box housing.
• Pliers will help you pull out damaged slats or straighten bent components.
• Use a measuring tape to confirm the replacement slats are the correct size.
• Gloves protect your hands while handling sharp edges.
• Replacement slats should match your current shutter model, such as Series 400, 450, or 560.
• Adhesive or sealant to lock out moisture and fix cracks.
• Lubricant supports smooth operation post-repair.

Step-by-Step Repair Guide

1. Removing Damaged Slats

Unroll the shutter curtain, and locate the box housing. Use a screwdriver to remove the end caps and access the slats. Then, slide out the damaged slats one by one. You may need to use pliers to remove the slats if they are stuck.

2. Preparing the Area

Clean the area of any debris or broken pieces for a smooth installation. Next, check the alignment and condition of adjacent slats and make adjustments, if necessary.

3. Installing Replacement Slats

Measure the slats you’ve removed to ensure the replacements are the correct size. Slide the new slats securely into the guide rails, starting from the bottom.

4. Securing the Slats

After replacing all damaged slats, reattach the shutter’s box housing and end caps. Finally, test the shutter to confirm it rolls up and down easily with no misalignment.

Preventative Measures

Regular maintenance can go a long way in preventing future damage and extending the lifespan of your rolling shutters. Here are some steps you can take:

1. Dust and debris can accumulate over time and negatively affect the shutters’ functionality. Clean the slats and guides periodically with a damp cloth.
2. Apply a lubricant to the guide rails and roller mechanisms every few months to ensure smooth operation.
3. Handle manual shutters gently, particularly when opening or closing them. If they seem stuck, don’t force them; instead, inspect for obstructions or damage.
4. Shutters with an AnchorLoc End-Retention System keep slats securely in the guide rail and provide additional resistance to impact.

When To Call a Professional

Professionals have the experience and equipment to tackle shutter repairs efficiently. While doing it yourself can be great for managing minor repairs, the following situations require professional expertise:

• If multiple slats or the internal mechanism are damaged, professionals will conduct repairs correctly.
• If your shutters are under warranty, contacting your DefendaGuard dealer for repair might be your safest option.
• If the shutters are motorized, they will require specialized tools and expertise beyond a DIY fix.
