Barndominium & Carport Corrosion: Assessment & Intervention

Covered and exposed purlins, whether galvanized or painted steel, serve as key structural elements in barndominium and carport roofs. In coastal regions, purlins that are exposed to salt air, even under roofs, are particularly vulnerable to rust due to salt buildup, which accelerates corrosion. Metal that isn't regularly rinsed is even more susceptible to this damage. Regular cleaning and the application of protective coatings are essential to prevent rust and extend the lifespan of these structures.

An assessment involves a thorough inspection of the carport for any existing damage. In most cases, intervention requires the use of a scissor lift. The entire process, from damage removal to applying protective measures, typically takes a minimum of two days to complete.

Additional concerns include the sealant between the exposed purlins and the house or shop, which may potentially allow water to leak into the building. Another important issue is the need to add drainage holes in areas where water tends to pool.

Initial assessment identified several areas of concern with signs of corrosion under the carport. If corrosion is present, intervention is required to prevent structural damage. Intervention consisted of removing the present damage.

The intervention process took three full days of work for over five hundred and thirty feet of exposed purlins. Finished photos below.
