More than a conventional exposed roof
Why Roof Decks and Green Roofs Need Integrated Waterproofing
An occupied roof may include walking surfaces, railings, doors, walls, drains, planters, equipment, and penetrations. Each element creates a transition where the waterproofing system must remain continuous while moving water toward an outlet.
Green roofs add soil, vegetation, irrigation, drainage layers, and long-term moisture exposure above the membrane. The waterproofing must be coordinated with protection, drainage, and root-management components before the planted assembly conceals access.
We evaluate the substrate, existing membrane, drainage, penetrations, terminations, finishes, and occupied space below. The recommended scope depends on whether the project involves new installation, restoration, a localized leak, or broader system failure.
Know the warning signs
Signs of Roof Deck or Green Roof Waterproofing Failure
Moisture can travel below traffic surfaces and planted layers before appearing inside the building.
- Stains, drips, bubbling paint, or dampness in rooms below
- Cracked, blistering, separating, or punctured roof deck coatings
- Standing water, slow drainage, or blocked drains and scuppers
- Leaks near doors, walls, railings, posts, planters, or equipment
- Loose pavers, tile, decking, or deteriorated traffic surfaces
- Persistent moisture near planted areas or irrigation lines
- Repeated patching without a confirmed moisture entry point
- An aging membrane concealed below difficult-to-remove finishes
Professional waterproofing solutions
Roof Deck and Green Roof Waterproofing Services
Waterproofing, drainage, protection, and the overlying use must be planned as one assembly.
Occupied Roof Decks
Waterproof systems protect terraces, patios, amenity decks, and walking surfaces located above occupied space.
Green Roof Membranes
Membranes are coordinated with protection, drainage, root-management, soil, vegetation, and irrigation layers.
Planter Waterproofing
Planter walls, bases, drains, terminations, and adjacent deck transitions are treated as a continuous wet-area assembly.
Paver and Tile Roof Decks
Hidden membranes and drainage paths protect the roof below pedestal pavers, tile, stone, and other finished surfaces.
Drain and Penetration Repair
Leaks around drains, scuppers, walls, doors, rails, pipes, and equipment supports receive focused evaluation.
Membrane Repair and Restoration
Existing systems are evaluated to determine whether targeted repair, recoating, selective replacement, or full replacement is appropriate.
A complete, condition-based approach
Our Roof Deck Waterproofing Process
Every layer above the membrane affects future access, drainage, and performance.
- EvaluateWe review the substrate, membrane, finishes, planters, penetrations, drainage, transitions, and occupied areas below.
- CoordinateThe waterproofing scope is aligned with traffic surfaces, green roof layers, drains, walls, doors, and equipment.
- PrepareFailed materials are removed and the substrate, cracks, joints, penetrations, and transitions are repaired.
- WaterproofThe selected membrane and reinforcing details are installed continuously across the prepared roof deck.
- ProtectProtection, drainage, and finish requirements are reviewed before pavers, tile, decking, soil, or planting layers conceal the membrane.
Residential and commercial experience
Roof Deck Waterproofing for Homes, HOAs and Commercial Properties
We work on residential roof terraces, apartment and condominium amenity decks, commercial roof decks, podium-like occupied surfaces, planters, and green roof areas. Projects can involve a single leak, restoration of traffic coatings, selective membrane access, or a new assembly.
Because the membrane may be concealed below heavy or sensitive finishes, early planning is especially important. Drains, overflow paths, thresholds, wall terminations, railings, equipment, irrigation, and planted areas must be coordinated before access is covered.

Common questions
Roof Deck & Green Roof Waterproofing FAQs
Can a roof deck be waterproofed below pavers or tile?
Yes. A compatible membrane and drainage assembly can be installed beneath pavers, tile, stone, or other traffic surfaces. Drains, thresholds, walls, penetrations, and future access must be coordinated.
What makes green roof waterproofing different?
Green roofs place drainage layers, soil, vegetation, roots, and irrigation above the membrane. Waterproofing must be coordinated with protection, drainage, root-management, terminations, and planter details.
Can you repair a leak without removing the entire roof deck finish?
Sometimes selective access is sufficient, but concealed moisture can travel beneath finishes. The extent of removal depends on the likely entry point, membrane condition, substrate, and how the finish is installed.
Why does water collect on my roof deck?
Standing water may relate to slope, settlement, blocked drains, limited outlets, raised finishes, or changes made after the original installation. Drainage and waterproofing conditions should be evaluated together.
Do planters on a roof deck need separate waterproofing?
Planters require continuous waterproofing, compatible drainage, protected terminations, and careful connections to the surrounding deck membrane. Irrigation creates prolonged moisture exposure.
Which areas do you serve?
Our service area includes Santa Monica, Beverly Hills, Malibu, West Hollywood, Marina del Rey, Manhattan Beach, Van Nuys, Woodland Hills, Calabasas, and surrounding Los Angeles communities.
