Drip Edge Roofing Replacement

What is drip edge

A drip edge is roofing component represented by an L-shaped piece of metal that is installed along the perimeter edges of a roof. The purpose of a drip edge on roof is to allow water to effectively run off while protecting roof edges and directing water away from susceptible areas. Replacing old or damaged drip edge roofing is important for maintaining roof integrity.

Why to Replace

  • To prevent leaks and water damage. Cracked or missing elements can allow water seepage, leading to wood rot, moss and mold growth and interior damage. Moss removal adds expences to your roof maintenance routine. Drip edge replacement closes up gaps.
  • To improve roof drainage and preventing ice dams. An intact drip edge allows stormwater runoff into gutters, preventing ice dam buildup which can lift shingles.
  • To stop pest access behind gutters. Replacing drip edge eliminates access points for pests to get under roofing materials.
  • To update appearance of aging roof edges. A new drip edge provides a straight, finished look to roof edges.

How to Choose the Right Drip Edge for Roof

When selecting the right type of drip edge for your roof, there are a few important considerations:

Drip Edge Materials

Common materials include, but are not limited to:

  • Aluminum — lightweight, resistant to rust and available in a variety of colors for coordination. It is generally the least expensive option and a popular choice.
  • Galvanized steel — offers increased durability and strength over aluminum, often with baked enamel coatings for extra longevity. Steel conducts less cold than aluminum.
  • For a unique look, opt for copper option, though it tends to be the costliest option. Copper naturally develops a protective green patina over time.



  • Match the color to your existing shingle drip edge or roofing if possible for a subtle finish. Consider coordinating with home exterior paint color as well.
  • For an accent look, choose material in a contrasting color like stainless steel over black shingles.
How to choose the color of drip edge. Use the rule of "match or contrast" to the color of your roof.


  • Standard — comes in 10’ lengths, need trimming during drip edge install. Custom bent pieces available.
  • Consider decorative styles, like bold profiles or scalloped edges on flat roof drip edge designs.



  • Use a minimum vertical flange height of 3-4” for proper overlap with underlayment and shingles.
  • Choose standard 6 inch drip edge width or wider 8”-12” sizes for extra roof runoff protection.
  • Shape needed is based on roof type—rectangular for sloped and L-shaped for flat roof.

When evaluating options, assess your roofing needs, climate, budget and the overall look you want to achieve before making a decision. Proper installation is also key, so speak to a roofer if unsure. Investing in premium option ultimately guards against leaks over time, saving on repairs.

Pro Tips on How to Install Roofing Drip edge Safely

  • Follow OSHA safety standards for roof access and fall protection
  • Make custom bends for non-straight roof shapes
  • Replace associated drip edge and gutters at the same time when possible

Installing new, high-quality roofing drip edge can go a long way in safeguarding your roof from expensive water damages. Pay attention to any signs of deterioration and address problems promptly. With the right materials and proper technique, a DIY replacement project can significantly extend your roof’s lifespan.

When to Call a Pro for Drip Edge Installation

While a  replacement project may seem straightforward, there are times when it’s best to have a roofing professional handle the install.

Safety is a top concern when doing any roof work. Roofers have special equipment and training for safely accessing and moving around on steep, tall rooflines. Rather than risk dangerous falls, property damage or OSHA violations, contact a qualified roofing contractor to take on the risky process of tearing out old items.

Additionally, poor installation can result in serious leaks or other issues down the line. Improper seam sealing or failure integrateion with roof underlayment can undermine the protection it provides. A seasoned roofing professional has the right techniques to ensure the construction diverts water properly without gaps.

In some cases, local building codes require that certain roof modifications are completed by a licensed contractor only. Before attempting DIY  replacements during a full roof replacement, consult your municipal regulations regarding roofer licensing, permits and inspection requirements. Steep fines can apply for non-compliance. Leave your roof work to the experts from a reputable roofing company instead.


What are the benefits of drip guard roofing?

It offers several benefits: Water Diversion: It effectively diverts water away from the roof deck and fascia. Prevents Rot: By keeping water away, it prevents rot and decay in the roof structure. Enhances Appearance: It gives a finished look to the roof edges. Pest Barrier: Acts as a barrier against insects and small animals.

Is there a difference between standard and clay drip edge?

Yes, the main difference lies in the material. A clay  model is typically used in conjunction with clay tile roofs and is designed to complement their aesthetic and functional requirements. Standard models are usually made of metal and are more versatile, suitable for a variety of roofing materials.

Are drip edges effective against wind-driven rain, and what types are best suited for areas with strong winds?

They are indeed effective against wind-driven rain, offering an additional layer of protection for your roof. In areas prone to strong winds, it's essential to choose models that are robust and securely fastened. Among the types of drip edges, those with a wider flange and made from heavier gauge materials are typically more effective in such conditions. They provide a stronger barrier against wind-driven rain, reducing the risk of water infiltrating under the shingles and causing damage to the fascia board and roof structure.

What is the difference between gutter aprons and standard drip edges, and how do they contribute to roof protection?

Gutter aprons and standard drip edges, while similar in function, differ slightly in design. A gutter apron is designed specifically to direct water into the gutter system. It extends further into the gutter than a standard drip edge, ensuring that even in heavy rain or wind, water is channeled effectively into the gutters. This design is particularly beneficial in providing protection against water damage by preventing water from bypassing the gutter and damaging the fascia or soffit. In contrast, standard items are more focused on preventing water from getting under the shingles at the roof's edge. Both play crucial roles in the overall layer of protection for the roof and the home's structure.
