Rooftop waterproofing
Rooftop waterproofing acts as the frontline defense against water intrusion into buildings. Flat roofs face sun exposure, temperature cycling, and ponding risk, so detailing matters. Vital spots include around roof penetrations, parapets, and equipment such as heating distribution manifolds. Choosing a compatible membrane and proper attachment method reduces long-term maintenance needs.
Opt for membranes with UV resistance and proven adhesion to concrete, metal, or wood decks. Ensure a deliberate slope toward drains and install flashings that seal transitions to walls. Around penetrations like condensate lines and heating distribution manifolds, use tested sealants and metal flashings. Before completion, perform adhesion tests and a careful coating cure to avoid microcracks later.
Exterior wall sealing
Exterior wall sealing helps prevent water from tracking back to the roof edge and attic spaces. Cracks, joints, and window frames create potential leaks unless addressed with compatible sealants and membranes. Keep expansion joints sealed and use wind-driven rain barriers to maintain continuous protection.
Regular inspections after storms reveal failed sealants before moisture penetrates insulation. Gutter maintenance and proper flashing at roof-wall transitions reduce water ingress. Document repairs to guide future budgeting and ensure consistent protection over time.
Bathroom waterproofing
Even in rooftop environments, wet areas like roof terraces with bathrooms require durable waterproofing from substrate to tile. Choose cementitious or flexible membranes suitable for showers and floors, compatible with substrate adhesives. Achieve correct slope toward drains and use transition details that prevent water from seeping under finishes.
Inspect joints around fixtures and penetrations, including any plumbing lines that pass through the roof. Regular resealing of grout and reapplication of sealants every few years keeps the barrier intact. Moisture meters or infrared scanners help detect hidden leaks behind tiles before damage spreads. Maintaining a maintenance log aids timely repairs and preserves roof lifespan.
