How To Install Rain Diverters for Roofs

Rain diverters for roofs are crucial because they direct water away from your house, protecting the siding and keeping your walls dry. Unfortunately, diverter installation is occasionally impossible, owing to a home’s architecture. So you’ll need something else to replace it, whether practical or ornamental.

What are Rain Diverters?

Rain diverters, also known as water diverters, are metal strips strategically placed under the roof shingles to redirect rainwater sideways. These devices are essential in collecting and guiding water away from entryways, preventing it from pouring directly over doors and windows. They are made in either a J or an L profile.

Despite their superiority over gutter replacements, rain diverters also have several disadvantages. Diverters especially give ice dams a footing in colder areas. They may also be ugly, particularly given how they tend to disrupt the uniformity of a roof’s look.

However, rain diverters might be fantastic if they don’t bother you. They’ll be able to provide your walls and siding with some protection, preventing the need for siding repair in the future.

The Purpose of Rain Diverter

  1. Moving Water Sideways

The primary purpose of a rain diverter is to act as a water diverter, effectively channeling rainwater in a specific direction. This simple yet ingenious solution involves installing shaped metal strips beneath the roof’s surface, ensuring that water is diverted away from critical areas of your home.

Homes often place these over their entrance doors. When it rains, the diverters keep water from entering the house by diverting it away from the doorways.

  1. Rain Diverter Profiles

Pre-fabricated rain diverters are available in either the J-profile or the L-profile. Under the shingle course above, they are screwed down and sealed with sealant. The course slopes and allows proper drainage with the tapered top edge tucked into the ground.

A thicker profile on each panel might stiffen it. You require a qualified roofer to assist you in installing them for this.

Rain diverters for roofs are not only functional in redirecting water but also play a crucial role in protecting the structural integrity of your home. By diverting water, they help prevent the formation of puddles that can lead to leaks and water damage.

Additionally, these diverters can be instrumental in preventing the buildup of ice dams in colder climates, further safeguarding your roof from weather-related damage.

  1. Install your ladder so you can access the roof.
  2. To remove obstructed roof shingles, use a flat pry bar.
  3. Lift the shingles, slide the diverter in, and secure with roofing nails, being sure to tuck each nail under a shingle.
  4. Apply a 1/4-inch thick bead of silicone caulk on the bottom of the drip edge.

  6. Use a garden hose to spray water over the roof to evaluate the rain diverter’s performance.

Your project is complete if your roof diverters pass the test.

Tips On Installing Rain Diverter for Shingle Roof

You must loosen up a few shingles to install rain diverters for your roofs. You may gently and slightly lift them with a pry bar. Please take caution not to peel or tear any obstinate shingles. Engaging a specialist for this work is preferable because it can require some accuracy.

Additionally, the rain diverter for a flat roof needs to be fastened. The diverter’s back should be where the nails are placed so the shingles will cover the nail holes. Finally, experts advise coating the nails with liquid cement to stop leaks.

When installing rain diverters, it’s important to consider the type of roof you have. For instance, the installation process might differ slightly for roofs with different materials or slopes. It’s also essential to ensure that the diverter is positioned correctly to collect and channel water efficiently without causing any obstruction to the roof’s drainage system.
