Critical Issue

The Dangers of Poor Drainage

Inadequate roof drainage is one of the leading causes of premature roof failure and building damage

Ponding Water

Standing water accelerates membrane deterioration, promotes mold growth, and adds thousands of pounds of weight to your structure

Structural Overload

Clogged drains can cause water accumulation that exceeds design load limits, risking structural collapse

Ice Dams

In winter, inadequate drainage leads to ice formation that blocks proper water flow and damages roofing materials

Interior Damage

Overflow and leaks from failed drainage cause expensive interior damage to ceilings, walls, inventory, and equipment

Vegetation Growth

Ponding water creates ideal conditions for algae, moss, and even tree saplings to take root in your roofing system

Voided Warranties

Most roofing warranties are voided if ponding water persists for more than 48 hours after rainfall
