Covered docks & boathouses FAQ
Can I add a roof to my existing dock?
Often yes. SCDES lists roofs on existing pierheads among the additions covered by a general permit (SC Department of Environmental Services, Critical Area Permitting: General Permits). Size limits apply, so your contractor should check before designing it.
Do covered docks hold up in storms?
A roof adds wind load. Ask the contractor how the roof and pilings are designed and fastened for coastal storms.
