Understanding the Role of Drip Edge in Roofing
Drip edge, an often overlooked yet crucial component of roofing systems, plays a pivotal role in directing water away from the roof and protecting the underlying structures. These metal flashings, typically L-shaped, are installed along the roof’s edges. Their primary function is to channel water into gutters, preventing it from seeping under shingles and causing damage. In North America, most building codes mandate the use of drip edges, underscoring their importance in safeguarding homes.
Material Choices for Drip Edge
Drip edges are available in various materials, each offering unique benefits:
- Copper: Known for its aesthetic appeal, copper drip edges add a distinctive golden hue to roofs.
- Aluminum: A popular choice, aluminum is corrosion-resistant and available in multiple colors to match different home styles.
- Galvanized Steel: Preferred for its ability to resist rust and handle water effectively, galvanized steel is a durable option, especially in 24-gauge thickness for wind resistance.
- Plastic, Vinyl, and Fiberglass: While less common, these materials are options in areas where metal drip edges are not readily available.
Profiles of Drip Edge
Drip edges come in three primary profiles:
- C Type: The classic L-shape, ideal for most standard roofing applications.
- D Type: Shaped like a T, also known as D-metal or T style, suitable for specific architectural needs.
- F Type: An extended version, often used for installing new roofs over existing shingles or on rake edges.
Standard drip edges are sold in lengths of 10.5 feet, with overhang lengths varying between 2-5 inches.
Color Selection for Drip Edge
Choosing the right color for a drip edge is largely a matter of personal preference and should complement the home’s overall aesthetic. For instance, a white drip edge seamlessly blends with white trim and fascia, while a gray one might tie in nicely with gray shutters or accents.
Installation on Existing Roofs
While typically replaced during new roof installations, drip edges can also be retrofitted onto existing roofs. It’s advisable to undertake this task during warmer months, as shingles can become brittle in cold weather.
Replacing Drip Edge During Roof Replacements
Although not mandatory, replacing the drip edge during roof replacements is highly recommended. An old, worn-out drip edge can detract from the appearance of a new roof and potentially shorten its lifespan.
Installation Process
- For C Type: Consider using a furring strip to enhance performance. This strip, installed under the roof’s edge, helps direct water away from the siding.
- Eaves Installation: Place the drip edge so that water flows into the gutters, with the flange pointing downwards.
- Securing: Use roofing nails every 12 inches, ensuring no section is left unnailed. Overlap each piece by at least an inch for continuity.
