Water runoff from your roof, especially in valleys and corners, can lead to issues like erosion, leaks, and even structural damage to your home over time. This is where a roof rain diverter comes in. In this comprehensive guide, we will explore what a roof rain diverter is, its benefits, and whether you should consider installing one on your roof.
What Is A Roof Rain Diverter?
Many people ask, why do I need a roof rain diverter when gutters can channel water away from the roof? While it’s true that gutters are an essential component of a roofing system, they can’t direct the water away from specific areas on the roof. Your roof isn’t one consistent plane, it has many ups and dips that can influence the path of the water flow.
Also, in many cases, the rainwater can fall around the home’s foundation due to the gutters overflowing, which can erode the soil and disrupt the landscaping. In such scenarios, installing a rain diverter is necessary for homeowners.
A roof rain diverter is a simple yet effective device designed to redirect rainwater away from specific areas of your roof. It typically comes in various shapes and sizes, catering to different roof configurations. The primary purpose is to prevent water from pooling in vulnerable spots, such as valleys and corners, where it can cause the most damage.
How Does A Roof Rain Diverter Work?
A roof rain diverter is a simple device that restricts water flow and directs it to the downspouts. Roof rain diverters are typically made of metal or sometimes PVC. Its flat surface is installed under the shingles, while the curved surface remains exposed to collect and channel the water in a desired direction.
Moreover, a rain diverter is strategically placed on the roof to make the correct angle with the water flow. If not installed properly, it may not work effectively, consequently becoming a cause for water seepage under the shingles.
Types of Rain Diverters
There are a few types of rain diverters, each made for different parts of the roof.
Roof Valley Rain Diverter
This type of rain diverter is specifically designed for roof valleys, where two roof slopes meet. Roof valleys are natural channels for water flow, and a roof valley rain diverter helps guide the water away from this vulnerable area, preventing potential leaks and erosion. Moreover, if there are problems with your roof valleys, water might not flow down them properly, making rain diverters even more crucial.
Corner Roof Rain Diverter
Corners of roofs can accumulate water, making them susceptible to deterioration. A corner roof rain diverter is shaped to fit snugly into the corner of a roof, redirecting water away and safeguarding these critical areas from potential damage.
Roof Rain Diverter Over Doors
Installing a rain diverter over doors is essential to protect entrances from water pouring off the roof during heavy rainfall. This type of diverter ensures that individuals entering or exiting the property are shielded from rainwater, preventing potential accidents.
How To Know If You Should Install Rain Diverters
Roofs, despite their sturdy construction, are susceptible to damage caused by rainwater runoff. That is why it is essential to identify whether you need a roof rain diverter.
1. Erosion Around Foundation
Inspect the area around your home’s foundation. If you observe signs of erosion, such as exposed roots or soil displacement, it suggests that rainwater is not being directed away from your roof effectively. Installing a rain diverter can help preserve the integrity of your foundation.
2. Water Pooling on the Roof
After a rainfall, take a moment to inspect your roof. If you notice areas where water is pooling or lingering, especially in corners or valleys, it indicates poor water drainage. Installing a roof rain diverter in these trouble spots can prevent potential damage.
3. Deterioration of Landscaping
Pay attention to the condition of your landscaping, particularly plants and flowerbeds near your roof’s drip line. Uncontrolled water runoff can lead to soil erosion and damaged vegetation. A rain diverter ensures water is directed away, preserving your landscaping.
4. Frequent Ice Dams in Winter
If you experience frequent ice dams during winter, it may be a result of poor water drainage on your roof. While a rain diverter primarily addresses water rather than ice, it can indirectly contribute to reducing the risk of ice dams by preventing water accumulation.
5. Water Stains or Leaks Inside
If you notice water stains on your ceiling or detect leaks inside your home, it could be a sign that rainwater is not properly diverted away from your roof. These issues often indicate that water is finding its way through vulnerable spots, emphasizing the need for a rain diverter.
How To Install A Roof Rain Diverter
Installing roof rain diverters is a straightforward process that can be accomplished by homeowners with basic tools. Here’s a step by step guide on how to install roof rain diverters:
1. Tools and Materials Needed
- Roof rain diverter kit
- Measuring tape
- Marker or pencil
- Sealant or roofing adhesive
2. Gather Necessary Tools and Materials
Ensure you have all the required tools and materials, including safety gear, ready before starting the installation process.
3. Measure and Cut the Rain Diverter
Measure the length needed for the rain diverter based on the identified problem areas. Most rain diverter kits come with clear instructions on sizing. Use a marker or pencil to mark the cutting points, and then cut the diverter accordingly.
4. Position the Rain Diverter
Carefully lift the bottom edge of the shingles and place the cut rain diverter on the identified problem area, ensuring that it covers the vulnerable spot where water tends to accumulate. Check that it is positioned to guide water away effectively.
5. Secure the Rain Diverter
Using a drill, secure the rain diverter in place with screws. Make sure it is firmly attached to the roof, ensuring stability during rainfall and windy conditions.
6. Seal Gaps and Joints
To prevent water from seeping through gaps or joints, use sealant or roofing adhesive to seal any areas where the rain diverter meets the roof. This is crucial for ensuring a watertight fit.
7. Adjust if Necessary
If you observe any issues, make necessary adjustments to the placement or angle of the rain diverter. It’s essential to ensure that it is effectively guiding water away from trouble spots.
A roof rain diverter is a practical solution to mitigate the potential damage caused by rainwater runoff. Whether you have a traditional pitched roof, a flat roof, or specific problem areas like corners and valleys, installing a rain diverter can contribute to the longevity and structural integrity of your roof.
