Drip edge is an essential component in roofing systems that is often overlooked but essential for the longevity and effectiveness of a roof. It is a metal flashing that is most commonly made from either galvanized steel or aluminum. Drip edge is installed along the edges of a roof to control the flow of water away from the fascia and protect all of the underlying roofing components.

What is Drip Edge?

Drip edge is designed to create a bridge that covers the builder’s gap ensuring water flows off the roof without seeping under the shingles or behind the gutter. It is usually installed at the roof’s edges, where the roof meets the fascia, and along the rakes (the sloped edges) of the roof. Available in a variety of shapes and colors, drip edge can be chosen to complement the overall aesthetic of your roof while providing essential protection.

What is a Builder’s Gap?

This is a gap between the fascia board (where the gutter is hung) and roof decking. This gap is caused when roof decking is stopped short and is not flush with the fascia. The gap is meant to help with airflow throughout the attic, however can come with major unexpected and costly consequences.

Why is Drip Edge So Important?

1. Water Damage Prevention:

The primary function of drip edge is to transfer water directly into the gutter system from your shingles. This eliminates the potential of water going between the two and causing damage to the roof decking, fascia board, soffit, rafter tails, and many other areas of your home, which would result in costly repairs. Over time, this could even compromise the structural integrity of the entire roofing system.

2. Protects the Fascia:

Fascia boards, located beneath the edge of the roof, can suffer from water damage if not properly shielded. Drip edge acts as a protective barrier, preventing water from running down the fascia and causing it to warp, crack, or rot. This extends the lifespan of the fascia and reduces maintenance costs.

3. Enhances Gutter Performance:

Properly installed drip edge ensures that water flows directly into the gutters rather than behind them. This minimizes the risk of water overflow, which can lead to foundation issues and landscape erosion around the home. It also reduces the risk of premature gutter failure, which is very common occurrence for many homeowners without drip edge installed. By channeling water correctly, drip edge supports and prolongs the efficient functioning of the gutter system saving you money and ensuring peace of mind.

4. Compliance with Building Codes:

In many regions, building codes now require the installation of drip edge as part of any new roofing system or when replacing a roof. This is due to its proven effectiveness in protecting the home from water-related damage. Failing to include drip edge in a roofing project can lead to non-compliance with local regulations, potentially affecting property values and insurance claims. The International Residential Code (IRC) has required drip edge to be installed along roofs ever since the 2018 edition, which Tennessee has adopted and currently enforces.

5. Extends Roof Lifespan:

By preventing water infiltration and protecting the roof’s edges from wind-driven rain, drip edge significantly contributes to the overall durability and longevity of the roof. This, in turn, helps homeowners avoid premature roof replacements and all other associated costs.

6. Pest Prevention:

Gaps between the roof edge and fascia can and very often do serve as entry points for unwelcome pests like insects, birds, and rodents. Drip edge helps close these gaps, providing an additional layer of protection against not just unwanted water but critters entering the attic or roof space as well.

Choosing the Right Drip Edge

Selecting the appropriate drip edge involves considering factors such as material, size, aesthetic appeal, and compatibility with your roofing system. Aluminum is a popular choice for its resistance to corrosion, while galvanized steel offers a more heavy duty layer of protection. Copper, though more expensive, is an option and provides a premium look and exceptional durability as well. To find out more about drip edge click here.

Conclusion

Drip edge may be a small component of the roofing system, but its importance cannot be overstated. By safeguarding against water damage, enhancing gutter performance, and complying with building codes, drip edge plays a critical role in maintaining the structural integrity of your home and offers a great return on investment (ROI) to all. Investing in quality drip edge installation is a wise decision that can prevent costly repairs and extend the life of your roof.
