by | Jul 15, 2023 | Blog | 0 comments

Water intrusion poses a significant threat to residential and commercial buildings, causing extensive damage and compromising structural integrity. In this article, we will explore the crucial role of drip edge in preventing water intrusion. Drip edge, an often overlooked component of roofing systems, is vital in redirecting water away from vulnerable areas and safeguarding your property. We will discuss the definition, purpose, installation process, maintenance tips, common mistakes to avoid, and additional measures to prevent water intrusion. Understanding the importance of drip edge and following proper installation and maintenance practices can protect your property from costly water damage.

Here is How Drip Edge Works

A drip edge is a roofing component specifically designed to manage water runoff. It has several vital components, including a horizontal flange, a vertical face, and a drip edge extension. Common materials used for drip edges include aluminum, galvanized steel, and PVC. The primary purpose of drip edge is to guide water away from critical areas such as eaves, rake edges, corners, and valleys. By directing water into gutters or away from the building, drip edge prevents water infiltration and potential damage to the roofing system and underlying structures.

The installation process of Drip Edge

1. Preparation and Safety Measures

Before installing the drip edge, taking safety precautions such as wearing appropriate personal protective equipment (PPE) and ensuring stable ladder placement is crucial. Additionally, gather the necessary tools such as measuring tape, snips, a hammer or drill, and roofing nails or screws.

2. Step-by-step Guide to Installing Drip Edge on a Roof

  1. Measuring and Cutting: Accurately measure the length needed for the drip edge along the eaves and rake edges. Use snips to cut the material accordingly.
  2. Preparing the Roof Surface: Ensure the roof surface is clean and debris-free. Remove any existing old drip edge if necessary.
  3. Installing Along the Eaves: Align the drip edge’s horizontal flange with the roof’s edge. Secure it using nails or screws, ensuring proper alignment and slight overhang beyond the fascia.
  4. Installing Along the Rake Edges: Install the drip edge along the rake edges, overlapping it with the eave drip edge. Maintain a consistent overhang and secure with nails or screws.
  5. Overlapping Drip Edge Sections: When using multiple drip edge sections, overlap them by at least 2 inches. It ensures a continuous water barrier.
  6. Securing the Drip Edge: Use roofing nails or screws to secure the drip edge, spacing them adequately to maintain stability and prevent potential lifting or damage.

Tips for Installing Drip Edge Around Corners and Valleys

When installing drip edges around corners, carefully miter the edges to ensure a proper fit. For valleys, trim the drip edge to match the angle of the roof slope, providing a smooth transition.

1. Benefits of Proper Drip Edge Installation

Adequately installed drip edge offers numerous benefits in preventing water intrusion:

– Prevention of water intrusion at vulnerable areas, such as eaves, rake edges, corners, and valleys.

– Protection against wind-driven rain and the formation of ice dams, which can cause significant damage.

– Reducing the risk of roof and fascia damage, preserving the structural integrity of your property.

– Extending the roofing system’s lifespan by minimizing water exposure and potential deterioration.

Maintenance and Inspection of Drip Edge

Regular maintenance and inspections are crucial to ensure the effectiveness of the drip edge system. Here are some essential maintenance tips:

– Clean debris from the drip edge and ensure clear drainage paths to prevent water backup.

– Inspect the drip edge for signs of damage or corrosion. Replace any damaged sections promptly.

– Repair or replace loose or dislodged drip edge components to maintain a secure and watertight seal.

Common Mistakes to Avoid

To ensure optimal water intrusion prevention, avoid the following mistakes:

– Improper installation techniques, such as failing to correctly align or secure drip edge components.

– Inadequate overlap between drip edge sections, leaving vulnerable gaps for water to seep through.

– Neglecting regular maintenance and inspections, which can lead to compromised functionality.

– Using low-quality or incompatible materials, compromising the effectiveness and durability of the drip edge system.

Additional Tips for Water Intrusion Prevention

In addition to drip edge installation and maintenance, consider these measures:

– Proper gutter installation and regular maintenance to ensure efficient water drainage.

– Adequate roof ventilation to prevent moisture buildup and minimize the risk of water damage.

– Addressing potential sources of water leaks, such as damaged flashing or compromised seals, promptly and effectively.


Drip edge is critical in preventing water intrusion and protecting your property from costly damage. You can safeguard your residential or commercial building by understanding the purpose of drip edge, following proper installation techniques, conducting regular maintenance, and addressing potential sources of water leaks.
