Do Gutter Guards Work in Heavy Rain?

Poorly Positioned Downspouts

If downspouts are not appropriately positioned or there are not enough of them, water may not be directed away from the house efficiently. This can lead to water pooling near the foundation.



Sagging Gutters

Damaged gutters can start to sag over time. When this happens, water may not channel properly, causing it to pool around the foundation of the house and overflow.



Ice Dams

In cold climates, ice dams can form on roofs and prevent melted snow from draining properly. This can then lead to water overflowing when temperatures rise.



Heavy Rainfall

In some instances, intense or prolonged periods of heavy rain can overwhelm gutter systems even if they are not damaged. This can result in overflowing water, especially when the volume exceeds the capacity of standard gutter systems.



What are the types of gutter guards that can work in heavy rain?

Do gutter guards work in heavy rain? Evidently, some types of gutter guards are designed to work effectively in heavy rain. Here are some common types:



Mesh Gutter Guards

Mesh gutter guards are designed with flat mesh screens to allow rainwater to pass through freely while preventing leaves and other debris from entering. The mesh screens are designed to withstand heavy rain, ensuring that they remain effective in all weather conditions. These durable gutter screens not only prevent clogs but also extend the lifespan of the gutter by reducing the risk of corrosion or damage caused by debris accumulation. Depending on the type of debris that you are avoiding, mesh gutter guards typically come in different aperture sizes.



Reverse Curve Gutter Guards

This type of gutter guard features a curved design to guide water into the gutter while preventing debris from entering. The curvature basically encourages rainwater to follow the curve and flow into the gutter system, while leaves, twigs, and debris are effectively diverted away. This innovative design not only ensures efficient water drainage but also minimises the need for regular cleaning.



Bottle Brush Gutter Guards

Bottle brush gutter guards are a versatile and low-maintenance solution for keeping your gutters clear of debris. Their cylindrical design with flexible bristles not only serves as an effective barrier against leaves, pine needles, and other debris but also allows easy installation on various types of gutters. These guards are resilient in different weather conditions such as heavy rain as they are made from durable and corrosion resistant materials. This makes them an efficient choice for homeowners looking to maintain a free-flowing gutter without the hassle of frequent cleaning and upkeep.



Foam Gutter Guards

Foam gutter guards typically consist of a foam inserts that effectively traps and filters out large debris from the water flowing through the gutter. This design aims to prevent clogs and maintain the smooth flow of water through the gutter system. Like other gutter protection system, foam gutter guards work efficiently in heavy rain as they create a barrier against debris while enabling water passage.



Nylon Gutter Guards

Nylon gutter guards are basically made out of nylon material, which are known for its durability, resilience, and resistance to weathering. These gutter guards work by allowing water to flow through while blocking leaves and other debris. Nylon gutter guards are incredibly lightweight, rust and corrosion resistant, and able to withstand various weather conditions like heavy rain. Not to mention, installing gutter guards of this type is easy and cost-effective.



Micro-Mesh Gutter Guards

Compared with typical mesh guards that have larger openings, micro-mesh gutter guards feature tiny openings that are designed to effectively block finer debris. These gutter guards are designed to work in heavy rainfall where minute debris are prevalent. Micro-mesh screen gutter guard provides an added layer of protection against clogs, so the gutter remains clear from even the smallest particles and water flows freely. block effectively.



How do gutter guards work in heavy rain?

Gutter guards are generally designed to prevent the accumulation of debris in gutters. But for them to work in heavy rain effectively, the following must be ensured:



Corrosion Resistant Gutter Guard

Not all gutter guards are corrosion-resistant. It primarily depends on the materials used in their construction. If you want your gutter guards to last long, choose ones that are made from corrosion-resistant materials such as stainless steel and aluminium. Some gutter guards are made of high-quality aluminium or steel and powder-coated for extra strength and long-lasting colour. They are resistant to rust and corrosion and tested to withstand harsh Australian weather conditions.

Optimised Aperture Size

Gutter guards come with various aperture sizes to control the passage of water and debris. Commonly measured in millimetres, the aperture size of the gutter guard indicates how much water will flow into the gutter while preventing larger debris, such as leaves and twigs, from entering. This ensures that the gutters remain clear and functional even during heavy rain.

While there isn't a one-size-fits-all standard aperture size for gutter guards, they typically range from 2mm to 8mm. Smaller openings are good for stopping small debris while letting water through. On the other hand, a slightly larger aperture may be suitable for areas with larger debris. All-Flow Aluminium Gutter Mesh offers gutter guards that are available in two aperture sizes: 3.5mm x 3.5mm and 2mm x 2mm.
