Storm and Wind Damage Assessment for Manufactured Homes

Why manufactured homes need a different post storm check

A site built house transfers wind load into a continuous foundation. A manufactured home transfers it through a tie down system into ground anchors, and holds itself up on a grid of dry stacked piers. Both of those systems can be disturbed by a wind event without the roof or siding showing much at all.

A gust that lifts one side of the home even slightly can unseat shims, tip a pier stack, or take up the slack in a strap and load an anchor hard. When the wind stops, the home settles back onto a support system that is no longer in the same condition it was that morning.

What an assessment looks at

Anchors and straps

Anchor heads are checked for lifting or tipping, since a hard pull can draw an anchor partly out of the soil. This concern is larger on Blackland clay after a dry spell, because shrinkage cracks reduce the confinement the anchor relies on. Straps are inspected for stretch, fraying, kinks and hardware damage.

Piers and shims

The crawlspace is checked for tipped stacks, cracked blocks, shims that have shifted or fallen, and any pier that has lost contact with the beam. A pier that is only slightly out of plumb after a storm will keep moving under load if it is left alone.

Frame level

Elevation readings tell whether the home moved as a unit or twisted. Twist is important because it shows up later as doors and windows binding on one end of the home only.

Skirting and perimeter

Missing, torn or displaced skirting panels are the most visible damage and also the easiest to underestimate. An open skirt lets wind driven rain into the crawlspace, which on clay means concentrated water going straight to the soil the piers bear on.

Water intrusion and drainage

After heavy rain the assessment includes where the water went. Washouts along the perimeter, new or widened soil cracks, and pooling near pier lines all change the bearing conditions under the home.

Documentation matters

If an insurance claim is involved, the written record from an assessment is what supports it. Photographs of each finding, elevation readings, and a clear description of what was disturbed give an adjuster something concrete. It is worth asking the contractor whether they provide a written report before work is scheduled.

Safety first

After a storm, hazards around a manufactured home include downed lines, unstable skirting panels with sharp edges, and open trenches or deep soil cracks that heavy rain may have widened or partly concealed. Open cracks and trenches in this ground are a recognized safety hazard, and they are harder to see when covered with debris or standing water. If the home appears to have shifted noticeably, staying out until it has been assessed is the right call.

The seasonal factor

Storms in this county often arrive at the end of a dry stretch, and that combination is the worst case for support. The soil is already cracked and has lost volume, the anchors have reduced grip, and then a large volume of water arrives quickly and runs down the cracks to pad depth. A post storm assessment on Blackland clay should therefore look at the soil condition as carefully as at the hardware.

Getting connected

This site connects Navarro County homeowners with independent contractors who assess manufactured home damage after severe weather. Describing what the storm brought (wind, hail, flooding) and what has changed since gives the contractor a head start.
