COMMERCIAL ROOFING / ST. AUGUSTINE, FL904-558-9951
Blackstone Roofing / Residential & commercial waterproofing

Waterproofing for homes & commercial properties.

Water intrusion can affect a home or a commercial building. Blackstone provides waterproofing, caulking, and sealant repairs at vulnerable details: where a roof meets a wall, a drain meets the membrane, or a joint moves with the building. Blackstone reviews those conditions on site and defines a compatible repair or restoration scope.

For homeowners

Keep water outside your home.

Have a recurring leak, deteriorating caulk, or an exposed roof or wall transition? We assess the affected area and recommend a repair scope suited to your home.

  • Exterior caulking and sealant replacement at joints and transitions
  • Window and door perimeter sealing where appropriate
  • Roof flashing, penetrations, and roof-to-wall details
  • Roof coatings and liquid-applied waterproofing where the existing surface is suitable
Ask about your home
For commercial properties

Protect buildings in daily use.

We work with owners, property managers, and construction teams on roof drains, parapets, wall interfaces, sealant joints, and liquid-applied details. Each scope accounts for the existing assembly, site access, and property operations.

Capabilities

Where we focus

  • Roof drains, penetrations, equipment stands, and curb transitions
  • Parapets, coping, perimeter edges, and wall interfaces
  • Fluid-applied weather barriers and exterior wall or window-opening scopes where specified
  • Liquid-applied detailing and sealant work where appropriate to the assembly
  • Documentation of existing conditions and a clear scope before work begins
Our approach

A scope built around the assembly

We look at the existing roof or building surface, drainage, access, substrate condition, and the cause of water entry. Product selection and preparation depend on those findings. An isolated leak may call for a targeted detail repair; broader deterioration may require a larger restoration or replacement plan.

Based in St. Augustine. Project coverage across Florida depends on scope, licensing, crew availability, and site requirements.
