Protecting your property: Why it’s important to protect your home from the sun 

We often consider the damage the sun can cause to our skin. However, have you ever considered the damage the sun is doing to your home?

Your home is likely your most important asset, so it’s important to protect it.

In Australia’s unforgiving climate, the sun can wreak havoc on the interior and exterior of your home, causing significant and often irreversible damage.

In this article, we explore how the sun can harm your home and provide you with practical solutions to combat it.

How the sun damages your home

The sun can cause timber to expand and contract, causing it to crack, split, or warp. In addition, decking oil may dry out, leading to cracking, peeling, and other wear and tear.

The sun’s rays can even cause concrete to crack, including the foundations of your home. Extreme heat can also cause the interior and exterior walls of your home to crack.

The sun can damage windows. For example, vinyl frames may crack and fade. Even the Low E Glass coating, which is meant to protect your home’s interior from the sun, can be damaged by the sun.

Your house’s siding is located outside and is often unprotected from the sun, meaning it is prone to damage. Wood siding may crack, split, and decay, while vinyl siding may become distorted and melt.

UV also causes exterior paint on your home to become faded. Darker colours are especially prone to fading as they absorb more sun. In addition, exposure to UV may crack the paintwork of your home. The sun can also fade and degrade fabric on outdoor furniture.
The sun can also cause your home’s roofing to expand and contract. Roofing materials are designed to be exposed to the sun. However over time, prolonged sun exposure can lead to warps, waves, and bubbles in your roofing. In addition, roof shingles may become cracked and separate. Rubberised sealants can also become dry and brittle, potentially leading to leaks.

Too much solar gain can also be counterproductive to the effectiveness of your solar panels. Solar cells and other materials may become damaged, resulting in poor sunlight conversion to electricity.

However, it’s not just the outside of your home you should worry about. Leather furniture placed near windows may also become cracked.

Once leather becomes cracked, returning to its original condition is difficult. The sun can also cause the interior décor of your home to become faded. Framed photographs and paintings placed near windows can also become bleached.

How to protect your home from the sun

One of the best ways to protect your home is by shading it.

While plants or blinds can help with this, a quality custom-made shade sail can provide comprehensive protection to your home’s interior and exterior.

Tinting your windows can also help protect your home’s interior.

Flooring can also be treated with UV protection finishes. Choose a lighter stain, as darker stains will fade more quickly and allow the floor to heat up more easily.

For short-term protection, re-paint your home’s siding. Lighter colours will provide better protection. Consider replacing it with light-coloured vinyl siding, fibre cement, or artificial stone for longer-term protection.

Given that most people consider their home their most valuable asset, it’s not only sensible but also a responsibility to shield it from the sun’s damaging effects as much as possible.
