Proper drainage is essential for roof longevity. We diagnose and correct drainage problems that cause premature roof failure.
Commercial flat roofs are designed with a slight slope to direct water toward drainage points. When drainage is inadequate or improperly designed, water pools on the roof, creating serious problems that lead to premature failure, leaks, and costly repairs.
Ponding water (water that stands on the roof for 48+ hours after rain) is one of the most damaging conditions for any roofing system. It accelerates deterioration, promotes algae growth, and adds significant weight load to the building structure.
Different drainage issues require different solutions
The original roof design didn't provide enough slope for water to flow to drains. This is common on older buildings or when roofs were added without proper engineering.
Too few drains for the roof size, or drains are improperly positioned. Each drain can only handle water from a certain area—exceed that and water pools.
The roof deck has deflection or sagging that creates low spots where water collects. Can be caused by age, structural issues, or added weight.
Drain bodies rust, crack, or separate from the roof. Clogs from debris prevent proper flow. Strainers may be missing or damaged.
We evaluate your roof's drainage system, including slope, drain placement, and capacity. We observe the roof during rain to identify problem areas.
We clear clogged drains, repair damaged drain bodies, and install or replace strainers. Many drainage problems are solved with simple maintenance.
When the original drainage is inadequate, we can add additional drains or scuppers to properly handle the roof's water load.
For roofs with insufficient slope, we can install tapered insulation panels to create proper drainage paths to existing drains.
Ponding water shortens roof life significantly. Get your drainage system evaluated today and protect your investment.
