What does the Wilmington climate do to a flat roof?
The Wilmington climate is coastal and harbor-exposed, with salt air, marine layer and heavy diesel and refinery residue combining to age roofs faster than weather alone would.
Metal drains and flashings corrode quickly, and residue softens asphalt surfaces.
How often should a Wilmington commercial roof be inspected?
A Wilmington commercial roof should be inspected twice a year, spring and fall, and the metal components on port warehouses deserve attention every time.
Corroded drains often leak long before the membrane shows wear. Our commercial roof inspection page explains what each visit covers.
