Mobile Home Hurricane Straps: Secure Your Home!
Believe it or not, a properly anchored mobile home can withstand winds exceeding 100 mph, often far surpassing the capabilities of structures anchored using outdated or improper methods. That surprising resilience hinges on understanding wind zones, using the right mobile home tie down systems, and adhering to local codes.
Understanding Wind Zones and Your Mobile Home
The first step in ensuring your mobile home's safety during high winds is understanding the wind zone in which it's located. Mobile home wind zone maps, typically provided by your local building department or available online through FEMA and state emergency management agencies, categorize regions based on their potential for wind speeds. Knowing your wind zone dictates the necessary anchoring requirements for your manufactured home. These zones are classified generally as Wind Zone I, Wind Zone II, and Wind Zone III, with Zone III having the highest wind-resistant standards.
It's crucial to remember that your mobile home was originally certified for a specific wind zone at the time of manufacture. This information is typically found on a data plate inside the home, often near the electrical panel or a kitchen cabinet. If you've moved the home to a higher wind zone, you'll need to upgrade the anchoring system to meet the new zone's requirements. Ignoring this can have devastating consequences. Statistics show that mobile homes improperly anchored in high-wind areas are significantly more likely to sustain severe damage during hurricanes and other wind events.
Assessing Your Current Anchoring System
Before considering any upgrades, thoroughly inspect your existing mobile home tie down system. Look for signs of corrosion, damage, or loose connections. Pay close attention to the ground anchors for mobile homes, the straps, and the points where they connect to the home's frame. If you find any issues, address them immediately. Even a small amount of rust can significantly weaken a tie-down, rendering it ineffective. Make sure the straps aren't rubbing against sharp edges, as this can cause them to fray and break under pressure.
Here are some key areas to check:
- Ground Anchors: Are they properly installed and embedded in the ground? Look for any signs of movement or leaning.
- Tie-Down Straps: Are they taut and free from damage? Check for cuts, fraying, or corrosion.
- Frame Connections: Are the straps securely connected to the mobile home's frame? Make sure the connections are tight and free from rust.
- Over-the-Top Ties: If your system includes them, inspect their condition and ensure they're properly tensioned.
Upgrading or Installing a New Anchoring System: A Step-by-Step Guide
Upgrading your mobile home's anchoring system is a significant undertaking, but it's essential for protecting your investment and ensuring your family's safety. If you're not comfortable performing this work yourself, it's best to hire a qualified professional. However, if you choose to proceed with a DIY mobile home anchoring project, follow these steps carefully.
Step 1: Planning and Permitting
Before you even buy materials, check with your local building department for any specific mobile home anchoring codes or permit requirements. Many jurisdictions require permits and inspections for anchoring work to ensure it meets safety standards. Failure to obtain the necessary permits can result in fines or even require you to redo the work. Also, consult the manufactured home foundation requirements for your area.
Step 2: Selecting the Right Anchors
Choosing the right types of mobile home anchors is critical. The type of anchor you need depends on the soil conditions and the wind zone. Common types include:
- Screw-in Anchors: These are relatively easy to install and are suitable for most soil types.
- Drive Anchors: These are driven into the ground with a hammer or powered driver and are best for dense soils.
- Concrete Anchors: These are embedded in concrete pads and are the strongest type of anchor.
Refer to the manufacturer's specifications for each anchor to determine its holding capacity and suitability for your specific needs. Don't cut corners on quality. Invest in anchors that are designed for mobile home anchoring and are properly rated for your wind zone.
Step 3: Installing the Anchors and Tie-Downs
This is the most labor-intensive part of the process. The following table illustrates the common spacing and requirements, but check local codes for adherence.
| Component | Description | Spacing (Typical) | Important Notes |
|---|---|---|---|
| Ground Anchors | The devices that secure the tie-down straps to the ground. | Typically spaced every 10-15 feet along the perimeter of the home. | Must be installed according to manufacturer's specifications and local codes. |
| Tie-Down Straps | Heavy-duty straps that connect the ground anchors to the mobile home's frame. | Correspond to the anchor spacing, ensuring each anchor is connected to the frame. | Should be made of weather-resistant material and properly tensioned. |
| Frame Connections | The points where the tie-down straps attach to the mobile home's frame. | Located at designated points along the frame, usually reinforced areas. | Must be securely fastened and free from corrosion. |
| Over-the-Top Ties (Optional) | Straps that run over the roof of the mobile home and connect to ground anchors on the opposite side. | Spaced according to manufacturer's recommendations and wind zone requirements. | Help to prevent the roof from lifting off during high winds. |
Follow these steps for each anchor:
- Locate Anchor Points: Determine the correct placement for each anchor based on your mobile home's frame and the manufacturer's recommendations.
- Install the Anchor: Install the anchor according to the manufacturer's instructions. This may involve screwing it into the ground, driving it in with a hammer, or pouring a concrete pad.
- Attach the Tie-Down Strap: Connect the tie-down strap to the anchor and to the mobile home's frame. Make sure the strap is properly tensioned and secured.
- Tensioning: Mobile home stabilization is important. Use a tensioning device (usually a turnbuckle) to tighten the strap. The strap should be taut but not overly tight. Overtightening can damage the frame.
Ensuring Proper Tension and Adjustments
Maintaining proper tension in the tie-down straps is crucial for the long-term effectiveness of your anchoring system. Over time, the soil around the anchors can settle, causing the straps to loosen. Regularly inspect the straps and adjust the tension as needed. A good rule of thumb is to check the tension after any major weather event, such as a heavy rain or a windstorm.
Use a tensioning device (turnbuckle) to adjust the straps. Tighten the turnbuckle until the strap is taut but not overly tight. Avoid overtightening, as this can damage the mobile home's frame. If you're unsure about the correct tension, consult a professional.
Hurricane Straps for Mobile Homes and Supplemental Protection
In high-wind areas, consider using hurricane straps for mobile homes to provide additional protection. These straps are designed to reinforce the connections between the roof and the walls, preventing the roof from lifting off during a hurricane. They are typically installed by professionals and can significantly increase your mobile home's mobile home wind resistance.
Beyond hurricane straps, consider these supplemental measures:
- Skirting: Install skirting around the base of your mobile home to prevent wind from getting underneath it.
- Window Protection: Install hurricane shutters or board up your windows before a storm to prevent them from breaking.
- Debris Removal: Remove any loose objects from your yard that could become projectiles during high winds.
Troubleshooting
Strap Corrosion: If you notice any corrosion on your tie-down straps, replace them immediately. Corrosion can significantly weaken the straps and make them more likely to fail during high winds.
Anchor Movement: If you notice any movement or leaning in your ground anchors, inspect them carefully. The anchor may be pulling out of the ground, or the soil around it may be eroding. If the anchor is loose, you may need to replace it or reinforce the soil around it.
Uneven Tension: If you notice that some tie-down straps are tighter than others, adjust them to ensure even tension. Uneven tension can put undue stress on certain parts of the mobile home's frame.
