What Is a Drip Edge On a Roof?

If you’ve ever noticed a metal strip running along the edge of a roof, that’s called a drip edge. Its purpose is to keep water from seeping under the shingles and causing damage to the roof or home. In this blog post, we’ll discuss what is a roof drip edge, why it’s important, and how to install one.

Why Are Drip Edges Important?

A drip edge is a small strip of metal installed at the end of a roof, usually just below the shingles. It serves two important purposes – firstly, it helps direct water away from the wood decking, preventing the wood from rotting due to prolonged exposure to moisture; secondly, it reduces the risk of ice dams forming in winter and causing damage to siding, eaves and even gutters. Furthermore, increasing building codes have made installing a drip edge an essential part of any roof installation or repair job – so much so that failing to do so could jeopardize your home insurance coverage. In short, a drip edge is not only an easy way to improve the long-term durability of your roof but also a wise investment in protecting your home and its contents.

What Are The Different Types Edges?

There are several different types of drip edges available on the market, including aluminum, copper, steel and vinyl. Aluminum drip edges are the most popular and economical option, while copper is a more high-end choice. Steel offers superior durability in extreme weather conditions and vinyl is a good choice for those looking for an easy to install product that won’t need painting or other maintenance. Additionally, there are specialty drip edge products made from rubber or plastic that can be used on low slope roofs.

No matter which type you choose, it’s important to make sure the drip edge is compatible with your roof material and installed correctly for maximum protection against water damage.

How to Install a Drip Edge

Installing a drip edge on your roof is an important part of protecting your home from weather damage. These help to create a barrier to help water disperse more evenly across the roof, preventing it from gathering along the edges and running down your walls. Installing one is relatively simple; however, safety should be top priority as you climb onto your roof. Begin by measuring around the edge of the roof to determine how much material you need for installation. Vinyl is typically available in 8-foot sections but can sometimes be found in 10-foot lengths. After purchase, attach it to the edge using galvanized roofing nails or concrete nails, depending on your roof material. As the final step, caulk any nails or large gaps to provide further protection against water entering your home. With some patience and vigilance, installing a drip edge will give your residence peace of mind during severe weather conditions.

Benefits of Having a Drip Edge on your Roof

Having a drip edge on your roof has tremendous benefits for protecting your roof, home and property. A drip edge helps protect your roof from water damage by directing rainfall away from the eaves of the roof, reducing the risk of standing water from pooling in one area. They also provide an extra layer of protection by covering fascia boards and keeping moisture from entering behind them. The additional coverage will help prevent potential for rot and roofing mold caused by excess moisture leaking underneath the edge of the roof. Having a drip edge installed on your roof will extend your roofs longevity and make it more impervious to any weather conditions that may threaten it over time.

What are Some Signs You May Need an Installation?

There are several telltale signs that you may need a drip edge on your roof. If you notice water stains or discolored patches on your walls or ceilings, it could be a sign that water is seeping in from the eaves of your roof. You may also find rusted nails or other metallic objects around the edges of the roof, indicating that moisture is entering the structure. Additionally, if you spot dark streaks or patches of algae on your roof, this could also be a sign that water is pooling and it may be time to install a drip edge.

Installing a drip edge on your roof can provide long-term protection from the elements and help keep your home or property safe. It is an easy and cost-effective way to help minimize potential water damage over time and should be considered when installing or repairing a roof.

Which Types of Roofs Allow for Installation?

Most types of roofs are designed to accommodate the installation of a drip edge. This includes asphalt shingles, metal roofing, slate and tile systems, as well as wooden shake or shingle-type materials. However, some roofs may not have the necessary space available for it to be installed correctly and safely. This includes roofs that have curved eaves or those with unusually wide overhangs. If you are unsure if your roof is capable of drip edge installation, consult a professional roofing contractor for advice.


In conclusion, a drip edge is a metal barrier that is installed along the eaves of roofs to help direct water away from the structure and prevent damage. It helps protect walls, ceilings and fascia boards against potential moisture damage and can extend the life of your roof. Installing a drip edge is simple but should be undertaken by an experienced professional whenever possible. Most types of roofing materials can accommodate drip edge installation, but it’s important to assess your structure first before attempting any installation. Taking the time and effort to install a drip edge on your roof will help protect your residence from future damage caused by water entry.
