Installing a Rain Diverter Above a Door: A Roofer’s Guide

Hey there, folks! I’m Ernie, and I’ve been in the roofing business since 1978. My family has been in the contracting game for three generations, so you could say I’ve got roofing in my blood. Today, I want to share some valuable insights into a simple yet effective solution for dealing with rain runoff above your door—installing a rain diverter.

What’s a Rain Diverter, Anyway?

So, you’ve got a situation where water runoff from your roof is wreaking havoc over your back door, and you don’t want to go all out with seamless gutters on your entire house. Enter the rain diverter, a handy piece of bent metal that can save the day. It’s about 10 feet long, and you’ll need to cut it to a length slightly longer than the area you want to protect.

Steps for Installation Rain Diverter

Let’s break down the installation process:

1. Measurement and Cutting

Measure the area you want to protect, typically a door, and cut the rain diverter to a size that’s a few feet longer. For instance, if you’re protecting a 6-foot door, cut it to around 8 feet.

2. Slipping It In

Slide the rain diverter up under the shingles, positioning it about two or three courses up from the lower edge of the roof. To do this, you might need to break the seal underneath a row of shingles using a thin pry box. Don’t worry; it’s easier than it sounds!

3. Pitch It Right

Ensure that the rain diverter is positioned to direct water away from the door area. You don’t want it running onto your patio. A slight pitch in the direction you desire should do the trick.

4. Securing It in Place

To keep the rain diverter in place, use 7/8-inch roofing nails to tack it down. Make sure to secure it firmly, so it doesn’t budge during heavy rain or wind.

5. Seal the Deal

To prevent any potential water seepage and to further secure the shingles, apply a generous amount of roofing cement on top of the rain diverter. This creates a watertight seal and keeps everything in place.

Why Use a Rain Diverter?

Rain diverters offer several advantages:

  • Cost-Effective: Installing a rain diverter is much more affordable than a full seamless gutter system.

  • Protects Your Door: It effectively redirects rainwater away from your door, preventing water damage and slippery surfaces.

  • Easy Installation: With the right tools and a bit of DIY spirit, you can install a rain diverter without much hassle.

  • Maintains Aesthetics: Unlike gutters that cover the entire house, rain diverters are discreet and won’t alter the appearance of your home.

Tips and Examples

To give you a better idea of how a rain diverter works, let’s consider a real-life scenario. Imagine you have a beautiful back door, and every time it rains, water pours down, soaking the area and potentially causing damage. A seamless gutter installation would be overkill in this situation. Instead, you can follow the steps I outlined above to install a rain diverter.

The rain diverter, once in place, will ensure that rainwater flows away from your door, keeping the area dry and safe. Plus, it won’t detract from the aesthetics of your home.
