Metal Roofing in Coastal Virginia

Salt exposure is a specification issue

Coastal atmospheres can accelerate corrosion on unsuitable metals, coatings and fasteners. In Hampton Roads, the Eastern Shore, the Northern Neck and the Middle Peninsula, the specification should reflect distance from the water.

Questions to ask

These distinguish a coastal-appropriate quote from a generic one.

• What substrate metal and coating system are proposed?
• What fastener and clip metals are used, and are dissimilar metals separated?
• Does the manufacturer warranty exclude coastal exposure within a stated distance of salt water?
• What maintenance, such as rinsing, does the warranty require?

Wind performance

Coastal Virginia's wind exposure makes attachment detail as important as corrosion resistance. Ask what wind rating the assembly carries and what installation achieves it.
