Why does my flat roof seem to have a better water collection system than my actual gutters?

Rain is great—until your flat roof starts treating the building like a swimming pool.
That’s where a proper galvanized gutter installation for a flat roof comes in.

For this project, the rear of the building will receive a new galvanized gutter designed to help move rainwater away from the flat roof and toward the existing downspouts. The goal is simple: keep rainwater moving in the right direction—not sneaking into places it has absolutely no business being. The existing downspouts will remain in place, keeping the current drainage setup intact.

The modified bitumen membrane from the flat roof will be heat-welded into the gutter to create a secure, watertight connection. In normal human language, that means fewer opportunities for water to find a tiny gap and start its unwanted indoor adventure.

A gutter on a flat roof system isn't just a piece of metal hanging around looking important.
Proper drainage is especially important for flat roofs because rainwater can sit on the surface instead of naturally running off like it would on a steep roof. A properly installed gutter helps direct that water toward the downspouts and away from the building.

Because the last thing anyone wants is a flat roof collecting water like it's preparing for a backyard pool party.
A properly installed galvanized gutter for a flat roof helps manage rainwater while providing a durable, sealed connection with the existing modified bitumen membrane.
When it rains, the water should have a clear exit strategy.
