Flat roofs are built to last — but even the best roofing systems can be compromised by one thing: poor drainage. As the seasons shift and we move into colder, wetter months, your roof’s drains and water-management systems quietly become the most important parts of your building’s protection.
The photo above is a perfect example. This roof has a clean, well-maintained drain and proper membrane detailing — exactly what you want to see before the freeze–thaw cycle begins.
Why Flat Roof Drainage Maintenance Matters More Than Most People Realize
Flat roofs are designed with subtle slopes that guide water toward drains, scuppers, or gutters. When that drainage system is blocked, damaged, or overwhelmed, three problems begin almost immediately:
1. Standing Water (“Ponding”)
Water that sits for long periods accelerates membrane wear, adds load to the structure, and increases the risk of leaks.
2. Freeze–Thaw Damage
As temperatures drop, trapped water freezes, expands, and forces its way into seams and flashings. This is one of the top causes of winter leaks.
3. Premature Roof Aging
Even small drainage issues can shorten the lifespan of the entire roofing system.
Seasonal Roof Drain Checks Make a Huge Difference
A simple inspection of your drains and surrounding membrane can prevent thousands of dollars in spring repairs. At A & K Construction, our seasonal service includes:
Clearing roof drains, strainers, and surrounding debris
Checking for membrane blistering or soft spots near drains
Inspecting seams, terminations, and flashings

Identifying risks before freeze–thaw cycles begin
These small proactive steps protect your building all winter and reduce emergency calls when the weather turns.
If Your Building Has a Flat Roof — Drainage Isn’t Optional
Whether your property is commercial, industrial, or multi-residential, proper drainage determines how well your roof performs. It's quiet, it’s unseen, and when it's working, you don’t even think about it — but when it fails, you notice fast.
A clear roof drain today is a dry building tomorrow.
