Roof and drainage systems are the moste vital elements that protects interior spaces, features and objects from damage. The following roofs need immediate attention:

  • Château-sur-Mer
  • Kingscote

Gutters/Downspouts: Repair and replace damaged or missing parts. Consider replacement using more historically appropriate design and/or materials. Tie into perimeter drainage system.

Remove tree limbs hanging over gutter system, and inspect bi-annually.

Grade: Clear foundation of plantings within four feet (4'). Regrade to achieve nine inches (9") of clearance between ground, siding, corner boards, or water table. Create positive grade away from structure to facilitate drainage.

In concert with assessment of the roof and drainage system, conduct structural analysis of roofing system and related structural components.
