Why Is Storm Damage Worse in Manufactured Homes?

The short answer

Lighter Build, Bigger Risk

Manufactured homes use lighter materials than site-built houses. Roofs, walls, and floors are designed for transport, not for extreme weather. That means wind and rain can cause more visible damage in a shorter time.

The metal roof panels often have seams that can pull apart under stress. Water then finds a path into the wall cavities and insulation. Once moisture gets inside, it can soak into framing and drywall, creating conditions for mold and rot.

Anchoring and Stability

Manufactured homes rely on tie-downs and anchors to stay put during storms. If those straps are loose, corroded, or missing, high winds can shift the home on its foundation. A small movement can crack plumbing lines and create gaps where water enters.

Older models may not meet current wind standards. Even newer units need regular checks of the anchoring system, especially after a storm passes. A quick inspection can reveal loose straps or bent supports before they become a bigger problem.

  • Check tie-down straps for rust or fraying after any storm
  • Look for gaps between the home and its skirting
  • Inspect the roof seams for lifted edges or tears
  • Ensure gutters are clear and downspouts direct water away
  • Trim branches that could fall onto the roof
  • Keep the area around the home clear of loose debris

Water Entry Points

Doors, windows, and vents in manufactured homes often fit into openings that are less sealed than in site-built houses. Storm-driven rain can push water past weatherstripping and into the interior. Once inside, water spreads along floors and up walls.

The underbelly of a manufactured home is another weak spot. Skirting can tear away, letting rain and runoff splash up into the crawlspace. That moisture can soak insulation and wiring, creating hazards and making cleanup more involved.

Interior Damage Spreads Fast

Inside a manufactured home, walls are often thinner and insulation is packed tightly. Water that enters a wall cavity can travel sideways along the studs and soak multiple rooms. The result is that a small leak can turn into widespread damage quickly.

Carpet and padding absorb water easily, and the subfloor underneath can warp. If you notice a musty smell or soft spots on the floor, water has likely been sitting for a while. Acting quickly to dry things out can limit the damage.

What You Can Do After a Storm

If a storm has hit your area, start by checking for obvious signs like torn roofing, shifted skirting, or water stains on ceilings. Turn off the power if you see standing water near outlets or appliances. See a doctor if you feel unwell from any floodwater exposure.

Local water damage pros can assess the extent of the damage and help with drying and repairs. If you live in Bellingham, keep your shutoff valve location written down so you can stop water quickly if a pipe breaks. Document everything with photos and notes for your insurance records.

Policies vary, and your insurer decides what is covered. The pros can also help with structural repairs after damage, but the work usually involves drying, cleaning, and rebuilding affected areas. The cost depends on how much water got in and how long it sat.

  • Shut off power if water is near electrical panels
  • Move valuable items to a dry area if safe
  • Remove wet rugs and furniture to help air circulate
  • Open windows and use fans to start drying
  • Call a mold professional if you see mold growth
  • Keep receipts for any supplies you buy for temporary fixes

Frequently asked questions

Can a manufactured home be repaired after storm damage?

Yes, many manufactured homes can be repaired. The extent of the work depends on how much water got in and whether the structure shifted. Local pros can dry out the home and replace damaged materials. If the frame is bent, structural repairs may be needed.

How long does it take to dry out a manufactured home?

Drying time varies with the amount of water and the weather. In a mild marine climate with wet winters, drying may take longer. The pros use equipment to speed up the process, but you should expect several days for full drying. Acting quickly helps reduce the time.

Should I file an insurance claim for storm damage to my mobile home?

Check your policy to see what storm damage it covers. Policies vary, and your insurer decides what is covered. Take photos and list damaged items before you call. Your insurer will guide you on the next steps. A claim may help with repair costs, but it depends on your coverage.
