Gutter Installation - Creative fix for a hard-to-drain flat roof

This gutter installation project on a home in Macomb Illinois had a drainage issue that wasn’t easy to solve. Water was spilling over the side of the flat roof during storms — even with an existing downspout through the soffit.

Here’s what made it tricky:

The roof is technically flat, but it has a slight pitch — and the fascia where the overflow occurred isn’t a common spot for gutter installs. Because of that pitch, the new gutter may look unlevel — but it’s actually set almost perfectly level, with just enough slope to drain properly.

Rather than recommending an expensive roof redesign, we delivered a clean, cost-effective solution:

✅ Installed a secondary gutter to catch overflow

✅ Tied it into the existing downspout (no extra foundation runoff)

✅ Used 3x4 downspout after the funnel to handle the volume

✅ Extended drip edge to make sure water goes into the gutter, not behind it

The result: Better protection for the deck, the fascia, and the foundation — without a major renovation.
