Roof Drainage Calculation

We provide roof drainage calculations to help you determine the most effective system design for your projects. Our assessment covers roof slope, rainfall intensity, and roof area to optimise gutter and downspout sizing, ensuring efficient water flow and preventing overflow, ponding, and long-term water damage.

We ensure full compliance with local building codes, Malaysia Standards, and regulatory requirements while coordinating with your roofing profile and overall roof layout. This service also supports accurate project planning and cost estimation, reduces site issues, and enhances the building’s durability through proper stormwater management.
