The term “drip edge” which is otherwise known as gutter aprons is a protective metal sheath that fits around the edge of your roof and protects it from moisture damage.
A drip edge is technically supposed to be part of any shingle roof manufacturer’s installation instructions but many homeowners may not be aware of what a roof drip edge actually is or what it does for a roof so minimal attention is usually paid to making sure it is often purchased.
Drip edges are responsible for protecting wood structures that are typically prone to rot and
Drip edges have two main functions: to divert water away from the fascia and to protect the roof’s deck from wind-driven rain.
A drip edge usually directs water into the gutter but in cases where your home has no gutter, the drip edge will work to prevent water from reaching the fascia and soffit cavity. This simple function can save you from extensive damage to your home.
Drip edges also help protect the wood structure beneath your roofing shingles from water damage and wood rot, allowing your
roof to last longer.
Drip compete with the wind and allows gravity to pull the water down before it goes under your shingles. This process prevents water from penetrating the shingles of your roof which can cause them to be weak and
result in quick roof damage.
Asides from the external protection role, drip edge can also prevent your roofing system’s deck and fascia boards from moving, allowing the entire system to be more structurally stabilized.
Drip edges come in different styles as well.
Depending on your choice, some are minimalist, some offer ornate borders, some have vents to allow air in and many more types.
Since drip edges can be easily omitted when roofing, during the initial process of pricing out roofing contractors and reviewing their estimates, it is important to check to see that the drip edge is included.
