Frequently asked questions
Which waterproofing method is best for a roof in Karachi?
It depends on the roof. Polyester reinforced membranes and elastomeric coatings are the most popular for houses and apartments, while APP or SBS bitumen membranes are used on larger commercial roofs. We recommend a system after a free inspection.
Do you provide a free site inspection?
Yes. Call or WhatsApp us and our team will inspect your roof, basement, tank or wall and give you a written quotation.
Can you stop leakage without breaking the roof or bathroom floor?
In most cases yes. We use surface applied membranes and injection grouting, so there is no need to remove tiles or demolish anything.
Do you work in other cities of Pakistan?
We are based in Karachi and handle projects across Sindh. For large commercial or industrial projects we can travel to other cities.
Will roof heat proofing reduce my electricity bill?
A reflective roof lowers the heat entering the building, so air conditioners work less. Actual savings depend on the building and usage.
