Name: Maxima Aluminum LTD

A drip edge may be one of the smallest details on your roof, but it plays a major role in protecting your home from water damage. If you live in the Greater Toronto Area, having a properly installed roof drip edge for gutters is essential—especially with the heavy rains, snow, and freeze-thaw cycles we get.

What Is a Roof Drip Edge?

A drip edge is an L-shaped piece of flashing that sits at the edge of your roof, directing rainwater into the gutters and away from the fascia. It’s usually made of aluminum, galvanized steel, or copper. Installed correctly, it helps prevent water from soaking into roof decking, trim, or siding.

How It Works With Gutters

When water flows off your shingles, the drip edge ensures it enters the gutter instead of seeping behind it. At eaves, it’s installed under the roofing felt; at gables or rakes, it’s placed over it. This smart placement helps shield the structure from rot and leaks.

Drip Edge and Ice Dams

Ice dams are common in Ontario and can cause serious roof damage. While a drip edge doesn’t prevent ice dams, it reduces the chances of water getting behind fascia boards if dams form. Combine this with good attic insulation and ventilation for best results.

Installation Tips

Keep a ¼-inch gap from the sheathing to allow proper runoff.
Use a 2-inch overlap between pieces.
Don’t nail too high—fasten to the roof decking edge.
