Steel Buildings in a Humid Climate
Metal building and shop insulation is common work around Houma, where oil and gas, shipbuilding, fishing and marine trades keep a lot of steel shops, warehouses and boat sheds in use. A bare metal building in Terrebonne or Lafourche Parish gets two problems from the weather. In summer the sun heats the roof panels until the inside is hotter than the outdoors. On cool mornings, humid air meets the cold steel and condenses, and the roof drips on tools, equipment and inventory.
Closed-cell foam on steel
Closed-cell spray foam sticks directly to metal panels and purlins, insulates, and keeps humid air from touching the steel. HomeGuide lists it at $3.00 to $5.00 per square foot installed. It also adds some stiffness to thin panels and seals the gaps at laps and fasteners. For a shop that is air conditioned or used as an office, more depth pays; for a storage building that just needs to stop dripping, a thinner layer may be enough.
Wind and repairs
The region has been hit hard: Hurricane Ida came ashore at Port Fourchon on August 29, 2021, with 150 mph winds, the strongest storm on record to land in Lafourche Parish. Many metal buildings were repaired or replaced afterward. If you are re-skinning or building new, spraying before interior liner panels go up is the easiest time.
Coatings and barriers
In spaces people work in, exposed foam usually needs a thermal or ignition barrier or an approved coating. We note on the quote where that applies, so you are not surprised later.
Residential shops
Many homes in the area have a detached steel garage or workshop. The same approach works at a smaller scale, and it often turns a hot, wet storage building into usable space.

Metal Building & Shop Insulation Questions
How do I stop my metal building from sweating?
Keep humid air from reaching the cold steel. Closed-cell foam on the underside of the roof and walls does that.
Will foam make my shop cooler in summer?
Yes, it cuts the heat coming through the roof panels. Ventilation or cooling still matter for a working shop.
Can you foam over existing fiberglass blanket insulation?
Usually the old facing has to come off or be firmly attached, because foam needs a sound surface. We check and quote removal if needed.
