Initial Roof Inspection and Consultation

An on-site inspection documents roof type, membrane condition, penetrations, drainage, and visible ponding or membrane failures, with roof area measured, existing layers recorded, and problem spots photographed for client reference. Building use, interior leak history, and maintenance access are reviewed to understand operational constraints, with budget range and expected service life discussed to align recommendations with client financial and asset-management goals.

Detailed Leak and Vulnerability Assessment

Non-destructive leak detection through infrared thermography or moisture scanning maps subsurface wet areas, with flashings, seams, roof-to-wall connections, gutters, and scuppers traced to pinpoint entry points. Rooftop equipment curbs, HVAC penetrations, and expansion joints are checked for compromised seals, with slope, drainage patterns, and runoff paths assessed to identify ponding risks and areas needing tapered insulation or improved drains. Deterioration severity is logged and repairs prioritized into immediate breaches, near-term failures, and preventative upgrades.

Solution Planning and Material Selection

A tailored waterproofing plan addresses detected failures and aligns with lifecycle cost expectations, with system selection covering elastomeric coatings, liquid-applied membranes, single-ply membranes, or reinforced sheet systems based on roof substrate, slope, and traffic. Primers, adhesives, flashing materials, and reinforcement fabrics are specified to match the chosen system and local climate performance needs, with flashing transition details, curb and penetration treatments, and drain interfaces included to prevent common failure points. A written proposal with scope, warranty options, material specs, cure times, and a disruption-minimizing work schedule is provided before approval.

Surface Cleaning and Preparation

Loose debris, gravel, and biological growth are removed to create a stable substrate, with pressure washing or soft washing completed and surfaces dried to manufacturer-recommended moisture levels before any application begins. Membrane laps are ground or seam-repaired, degraded flashing replaced, and failed coatings or blisters removed, with localized patching or new base sheets installed where saturation or delamination exists. Roof-mounted equipment, vents, and walkways are masked and protected throughout to maintain site safety and prevent mechanical unit contamination.

Waterproofing Application

Primers and moisture-tolerant base coats are applied per manufacturer instructions with temperature and humidity monitored for proper cure, followed by reinforcement installation at seams, curb transitions, expansion joints, and penetrations to create continuous durable seals. The primary membrane whether liquid-applied or sheet is laid with uniform coverage, correct thickness, and proper overlap, with termination bars, drip edges, and counterflashing installed and the new system integrated with gutters, scuppers, and existing wall flashings. Wet film thickness is measured continuously and cure times noted to prevent premature traffic or subsequent layer application.

Final Quality Assurance and Client Walkthrough

Adhesion and continuity checks, cured membrane thickness measurements, and flashing, drain, and penetration inspections confirm workmanship, with water tests or flood tests conducted in vulnerable zones where feasible. Completed work is documented with photos, material batch numbers, and as-built notes for warranty files and future maintenance planning, followed by a roof walkthrough with the client or facility manager covering new features, maintenance recommendations, warranty coverage, and post-installation support contact information.
