If you’re in the process of repairing or installing a roof on your home, you may have heard the term, “drip edge.” To some homeowners, drip edges may seem like just another roofing component. Many may also wonder whether it’s necessary to install them.
Allow us to break down all you need to know about a drip edge. You will get to know if it's a crucial component to include on your roof and whether it offers any form of protection.
What is a drip edge on a roof?
A drip edge is a metal flashing, which can be PVC-coated and installed on roof edges to control water flow. Through a drip edge, water can be directed from the fascia to the roof gutter without causing any structural damage. The fascia is a wooden board that runs along the lower edge of the roof. Without a drip edge, water can rot out the fascia board and roof decking. The water damage could also affect other parts of your home.
How does a roof drip edge work?
Roof drip edges are installed on your roof perimeter, typically at the eaves. When installed by an expert like Robust Roof, it perfectly covers the edge of the roof deck, preventing water from getting into the shingles. It can shed water efficiently through its partly curved design that redirects the water down into the gutter system.
Types of roof drip caps

Not every drip edge is a perfect match for every roof type. Preferences vary based on factors like thickness, type of coating, and even color in some cases. To decide on a drip cap for your roof project, here’s a clear overview of each type:
- Aluminum Drip Edges: Aluminum drip edges are lightweight and corrosion-resistant. When properly maintained, they can last over forty years even with exposure to various weather conditions. They are also relatively inexpensive, easy to install, and can be painted to the homeowner’s color preference.
- Galvanized Steel Drip Edges: Galvanized steel is from zinc-iron alloy, giving it a high corrosion resistance. Drip edges made from galvanized steel are known for their strength and impressive resistance against wind.
- Copper Drip Edges: Copper drip edges are relatively expensive in comparison to aluminum steel. They are stronger and more durable than galvanized steel. Most homeowners consider copper drip edges as an attractive option for protecting their roofs because they are aesthetically pleasing.
- PVC-coated Drip Edges: Metallic drip edges can also be coated with PVC membrane typically on single-ply roofing systems. It prevents moisture intrusion and eliminates the need for adhesive stripping in most cases. This style also allows the color to last longer and stay clean. You can see why this is a popular drip edge material.

Metal roofing drip edge
Apart from redirecting water to the roof gutter, you can install a drip edge on your metal roof to improve its appearance and to seal openings. Metal roofs with drip edges are more aesthetic compared to an overhanging metal roof because they appear cohesive to the eye as well as function.
The best type of roof drip edge for a metal roof is aluminum. It’s a great pick because it’s available in different colors and can easily match your metal roof. Aluminum roofs can also withstand a significant amount of pressure, making them a great choice.
Galvanized steel drip edges are also great because they can match your metal roof and in many cases, are stronger than aluminum.
If you have a metal roof, you may be aware of small openings that may seem insignificant. However, those “small areas” can give way to bats, bugs, birds, and pests in your home. This is why it’s crucial to properly install a drip edge by consulting a roofing contractor.

Drip edge install: can you do it on your own?
Yes, you can install a drip edge on your own once you have all the necessary knowledge and equipment. But, you need to weigh the risks. For instance, most DIY approaches to drip edge installation typically cost more in the long run due to high setup costs (buying or renting tools). There’s also a high risk of getting injured by the roof material. Drip Edge is most often custom bent to fit a roof in a particular manner and if you do not have previous experience in properly bending metal, you could end up with higher than normal material waste, due to mistakes.
