Everything homeowners need to know about protecting roofs and terraces before the monsoon hits.

Nepal's monsoon brings 80% of the country's annual rainfall in just four months. Preparing your roof before Ashar can save lakhs in repair costs.

Inspect before the rains

Check for hairline cracks in the terrace screed, blocked rainwater outlets and failed sealant joints around parapets.

Choose the right system

SBS modified bitumen membranes suit flat terraces; PU liquid coatings work best on complex profiles with many penetrations. Crystalline treatments are ideal for water tanks and basements.

Hire certified applicators

Waterproofing fails at the workmanship level far more often than at the material level. Always ask for an applicator certificate and a written workmanship warranty of at least 5 years.
