Frequently Asked Questions
How much does roof waterproofing cost per sqm in Saudi Arabia?
Roof waterproofing typically costs from 45–120 SAR/m² depending on system (bituminous, PU liquid, polyurea, or foam), roof condition, and access. Final pricing requires a free site survey.
How long does roof waterproofing take?
2–5 working days for typical villa roofs after preparation. 1–3 weeks for commercial roofs depending on area and weather.
What warranty do you provide on roof waterproofing?
Written workmanship warranty of 5–10 years depending on system type, substrate condition, and maintenance. Exact term is stated on the project quotation.
What roof waterproofing system is best for Saudi Arabia?
Systems must withstand extreme UV, thermal cycling and occasional heavy rain. Liquid-applied membranes and reinforced bituminous or PU systems are commonly specified for KSA roofs.
How often should a commercial roof be re-waterproofed?
Inspection cycles depend on exposure and traffic, but most commercial roofs in Saudi Arabia benefit from assessment every 3 to 5 years due to UV degradation.
Do you waterproof flat and podium roofs?
Yes. Pedox installs complete roof waterproofing systems for flat roofs, podiums, terraces and plant decks on towers and commercial developments.
Do you serve roof projects in Riyadh, Jeddah and Al Khobar?
Yes. Pedox executes roof waterproofing in Riyadh, Jeddah, Dammam and Al Khobar. See our city pages for local details.
