Do I Need a Drip Edge for Metal Roofs?

Deciding whether to install a drip edge on a metal roof is one of the best investments you’ll ever make. It’s true that metal roofing is highly durable and long-lasting, but no matter the roofing material, having a drip edge is an easy way to extend the life of your roof.

Due to its ability to divert water away from the roof and protect the edges of the roofing panels, installing a drip edge is critical for safeguarding your home, especially in rainy or snowy conditions. Additionally, a properly installed drip edge provides increased wind protection and extra security against pests and animal entryways.

What is a Drip Edge and How Does it Work?

A drip edge is an often overlooked component of a roof system, but, for the benefits that it brings, any good builder will take the time to add one. Water is always an enemy to homes and having a metal roof is no different, so the inclusion of a drip edge is an assumed aspect of building out a high quality roof.

The angle of the drip edge causes water to run off quickly from the roof’s edges, rather than saturating or seeping in, causing potential damage to the underlying structure, and even sheathing that may be underneath. Even with a weather barrier under the metal roof, further closing off a potential entrypoint for water is a great idea. Drip edges are available in various colors and materials — such as plastic, copper, aluminum or steel — and also provide form and function by creating a more aesthetic finished look while protecting the home.

Advantages of Using a Drip Edge

Reduces Maintenance

Installing a drip edge on a home is a smart move for homeowners looking to maximize the longevity of their property. When used with gutters, a drip edge helps keep water away from the top of the walls and foundation, protecting the home from potential water damage.

Improves Gutter Performance

A drip edge is an essential part of gutter performance because it keeps water away from the edge. This function of a drip edge is critical to:

  • Protect the metal roof and ensure that rainwater flows unobstructed into the gutters

  • Allow runoff to bypass your fascia board so you don't have any water saturation issues

  • Ensure that all unwanted moisture will be channeled away efficiently from your roof

Adds to Curb Appeal

A proper drip edge installation on a metal roof will also improve the aesthetic appeal of your home by providing a clean, crisp line at the roof edge.

Can Metal Roofs Benefit from a Drip Edge?

A drip edge is essential for metal roofing for the same reason it is essential with other roofing types: protection from water. Your rooftop's fascia board, which secures the gutters and prevents water from infiltrating into the deck, is especially prone to rot or other damage caused by water. A drip edge is the final safeguard for keeping the roof and walls safe.

In essence, adding a drip edge to your metal roofing system can help safeguard against water damage that could become costly if left unchecked in the future.

Curb Appeal

While a metal roof naturally delivers a clean perimeter on the roof, a drip edge can be color-coordinated to match the metal roof, providing an attractive transition from the roofing to the gutter. Investing in a drip edge will elevate your property's curb appeal and ensure it looks neat and presentable for years to come.

What is the Best Material for a Drip Edge?

Aluminum is an ideal material for a drip edge due to its light weight and durability. As it concerns metal roofs, the sharp edges and look of aluminum is perfect for the steel or galvalume that are used for metal roofs. Aluminum drip edges from Alsco Metals come in a variety of colors designed to pair well with the most common of metal roof aesthetics.
