What is a Drip Edge?
A drip edge is simply a narrow piece of metal (usually aluminum, steel, or copper) that is attached at one end to your roof edge and is left to hang down and direct precipitation flow off your roof. The primary function is to divert water away from your roof, refusing it from entering the fascia, soffit or sub-components.
Drip edges overhang the edge of the roof to provide a small lip, that allows water to drip safely into gutters and not into the fascia or back into the building. This straightforward creation has a major effect in preventing water damage.
Why is a Drip Edge Important?
Protects the Roof’s Integrity
Water without a drip edge can slide — it can be wicked — back up under the shingles and into the deck of the roof, and over time, create problems such as rot, mold and the deck losing its structural integrity. A well-placed drip edge gives a watertight seal and protects these sensitive parts of your roof.
Directs Water into Gutters
A drip edge helps to divert rain water into your gutters, protecting your home’s foundation from water related damage. Without these, water could run right over your gutters, causing soil erosion, a flooded basement and even foundation damage.
Extends Roof Lifespan
Water leaks, and water-related issues can shorten the life of not only your roofing but all of the other components of your home. Think of it as a health investment in your home.
Enhances Aesthetic Appeal
Besides protecting your home from water-related damage, a drip edge enhances the aesthetics of your roof by providing a clean, finished edge make your home look more attractive from the street.
Observance of Building Codes
A drip edge is a requirement in most new building codes. For example, if you forget to include one on your roof the building is no longer code compliant and various problems can arise when you try to sell or are inspected.
Types of Drip Edges
Drip edges are not universal. Here are the main types, broken down by specific uses:
Type C (L-Shaped)
Type C drip edges, the most prevalent choice, take the form of an “L.” They hold tight to the roof line and they really sweep the water away from the fascia and soffit. This variety is favoured for domestic and residential roofing.
Type D (T-Style)
Type D drip edges Type D or T-style drip edges are offered for extra protection. Their unique “T” profile helps disperse more water than the original style, meaning they are perfect for those parts of the country where heavy showers are a regular occurrence.
Type F (Overhang Flange)
This style features extra long flange for steep pitch roof or masonry chimney.
When selecting a drip edge, let both your roof’s design and material, as well as your local weather, dictate your choice.
How to Install a Drip Edge
The drip edge installation itself is a disciplined application. Here’s a step-by-step guide to doing the job properly:
Materials Needed:
- drip edge (aluminum, steel or copper)
- Roofing nails
- Roofing adhesive (optional)
- A metal snip or cutter
- Measuring tape
- Ladder and safety gear
Steps:
- Start by measuring the length of your roofline to determine how much drip edge material you’ll need.
- Begin in a bottom corner of the roof and move upward. Set the drip edge under the first course of shingles, and over the roof sheathing.
- Nail the drip edge in place with roofing nails, spaced every 12 in along the edge.
- Overlap drip edge segments by 2 in. to avoid gaps.
- Snip pieces with metal snips where necessary – around corners or bends.
- If you are adding a drip edge to an old roof, slide it under the shingle instead of lifting it out.
- Check for alignment, the lip should be long enough to keep any water from flowing back inside.
Though the installation is simple, you should have the help from a professional for larger and more complicated roofing.
Common Mistakes to Avoid
The effectiveness of a drip edge can be easily ruined by relatively simple mistakes made during installation. Beware these frequent flaws:
Skipping Overlaps
If the sections of drip edge do not overlap, water can get through the gaps. Overlap the pieces by 2 inches at all times.
Improper Placement
The drip edge can let water in if it’s put on top of the shingles and not underneath. - The proper location is under the initial shingle course.
Poor Fastening
Too few nails or nails spaced too far apart can cause the drip edge to rip away. Nails should be all placed and set properly.
Ignoring Compatibility
By choosing the wrong style of drip edge for your roof’s pitch or design, can limit its ability to preserve your roof.
Drip Edge Care and Repair
Maintaining your drip edges is essential for preserving your roof’s health. Regular maintenance includes:
Inspection
Inspect your drip edges on a regular basis for rust, wear or if the nails have come loose. Water stains, peeling paint or gaps where water could seep through are all potential signs that an exterior wall needs attention.
Cleaning
Keep gutters and drip edges free from leaves and debris buildup. Clogged rain gutters can make water spill over and cause damage.
Repairing Damage
Patch Cracks Try to replace damaged sections of pipe as soon as you notice that they’re cracked and/or rusted to avoid complications. For the best appearance and performance, use materials that are designed to work together.
Professional Checks
Arrange regular visits from experts to inspect the roof and particularly after major weather incidents.
