Sloped and flat roof waterproofing using APP membrane, liquid coating and elastomeric systems. Handles old rooftop repair and new builds.
Roofs are the primary line of defence against weather elements. In Bangalore, roofs endure prolonged monsoon rains, UV radiation, and temperature swings. Whether your property features a flat concrete roof, sloped tiled roof, metal sheet roof, or composite structure, improper waterproofing leads to moisture penetration, internal ceiling decay, and structural damage over time.
Prime Waterproofing Contractor delivers tailored roof waterproofing services across Bangalore. We assess roof slope, drain capacity, expansion joints, and surface material before recommending a suitable solution. Our technicians use high-grade waterproofing materials to seal every weak point, ensuring robust protection against rainwater infiltration.
Water leakage paths can travel meters away from visible damp patches. Before recommending any waterproofing system, our senior technician conducts a thorough site evaluation to pinpoint the exact root cause.
If you observe any of the following signs on your property, immediate diagnostic inspection is recommended:
Age-related degradation of original roofing materials and sealants
Thermal expansion causing joint separation in roofing structures
Improper installation or clogged rainwater gutter drainage systems
Corrosion around roof sheet bolts, J-hooks, and flashing joints
Unsealed roof penetrations from solar panels, dish antennas, or HVAC units
Every project follows a structured engineering workflow to ensure complete moisture barrier performance:
Thorough inspection of roof gradient, joints, flashings, drains, and roof sheet condition.
Removing moss, dirt, rust scale, or decaying sealants with pressure washing.
Sealing roof joints, overlaps, ridge caps, and fastener holes with polyurethane sealant.
Applying surface-compatible primer coat to maximize coating adhesion.
Applying multi-coat elastomeric or bituminous roof membrane system.
Reinforcing roof perimeter edges, wall flashings, and downspout entries with mesh reinforcement.
Quality verification of thickness, continuity, and drainage flow path.
Seamless liquid coatings that cure into a flexible rubberized membrane ideal for flat and sloped roofs.
