Why a Roofing Drip Edge is Necessary

A roofing drip edge is an L-shaped metal piece that is attached to the edge of the roofing system. It plays an important role in preventing water damage by directing water away from the fascia and into the gutters. Roof edges are sold in different lengths to accommodate a range of roof shapes, sizes, and dimensions.

Though many roofing contractors usually replace damaged roofing drip edges, in many cases, an old roofing drip edge can be safely and reliably reused by introducing minor tweaks.

Continue reading to learn why most roofing companies in Marin highly recommend a drip edge for homeowner’s roofs.

Why Install a Roofing Drip Edge?

Usually, a non-corroding and non-staining material is used. Some popular roof drip edge materials include aluminum, copper and galvanized steel. When selecting the roofing drip edge material, make sure it blends in with the rest of the roof.

A roofing drip edge is installed with an intended tilt to direct water away from the roof. Damaged or rusted edges should be replaced as soon as possible to prevent any serious damage.

Without a drip edge, shingles allow water to get underneath the roof, leading to water damage. Before, drip edges were an afterthought. However, now they are actually required for most buildings in the country.

In addition to directing water away from the fascia, a roofing drip edge protects the roof’s deck from wind-driven rain, which can cause serious damage in a short period of time.

A roofing drip edge can also be the answer to your pest problems. When winter arrives, pests hornets looking for warm places can chew through your roof to get inside. A roofing drip edge can help keep critters at bay by covering the gaps that they use in order to get access to different parts of a roof and then get inside the home.

The Right Way to Install a Roofing Drip Edge

When drip edges are installed properly, their outer edges extend beyond the gutters.

When installing roofing drip edges, make sure the horizontal edges overlap by an inch. This is important to ensure there are no gaps that can allow water to get inside the roof and home.

Special cement is used to evenly distribute the weight of the drip edge along the roof’s edge and shingles. This minimizes unnecessary penetrations that can cause roof leaks to develop.

In some cases, contractors use short roofing nails to secure the roofing drip edge. Ensure the penetrations are high up under the shingles to reduce the risk of water infiltration.

Typically, roofers first install the drip edge and then the shingles. However, if the edge is damaged and other parts of the roof are holding up fine, you can install a new edge without disturbing the shingles.
