Securing Solar Panels: Expert Guide to Roof Installation

Solar panels are a crucial part of energy efficiency, and the process of making sure they are well-attached to your roof is part of the puzzle. This article details which types of roofs are appropriate for these structures, explains the installation techniques used by contractors for various types of roofs, and emphasises the need to hire a reputable installer.

Attaching Panels to Metal Roofs

Many of these will be clip lock and corrugated metal roofs. Solar installers typically use a system similar to a regular kitchen rack, with a range of clamps and brackets. The idea is to attach the solar system’s metal racking and rails while minimising the amount of drilling into or penetrating the roofing sheets as much as possible – that will limit the opportunity for leaks, and your roof will not be compromised either.

Solar Installation on Tile Roofs

Tile roofs take a little longer to prepare for solar installation, as the tiles usually first have to be removed and chiselled down to enable the installation team access to the timber rafters supporting the tiles. The steel brackets that the array of racking components will bolt to are then secured to the timber rafters. Once the brackets are in place, the tiles are usually rebedded, a process in which specialised materials are installed in high-precision grooves on the bottom of the tiles. In this case, the tiles are topped with silicon adhesive or special waterproof cement and then re-laid upon the rafters.

Quality and Expertise Matter

Whether you have a flat ‘walkable’ roof or not, the quality of the installation is still the most important factor, and the reputation of the company is critical. A high-quality installer will meet the warranty terms and take additional steps to ensure the system is installed properly and operates as effectively as possible. For example, by using deck tights in penetration areas versus ‘one and done’ such as a silicone sealant, which can act as more of a premium and more sustainable solution for preventing roof leaks.

The Importance of High-Quality Installation Components

Beyond just the physical installation of them, the quality of the installation components (eg, the cabling, electrical safety elements, and the other parts of the system) are important to consider too – it’s those that add up to the quality and performance of your solar power system.

Conclusion

Even questions of how solar panels should be fitted require some context – while there are some universal factors when it comes to solar panels and roofs (everyone must decide to have the panels attached, of course) – fitting the solar panels to a slate or tile roof will be different to fitting them to a flat roof, and a skilful installer will make all the difference from an adventurous DIY enthusiast.

Key Learnings and Homeowner Insights:

• Different roof types require specific installation techniques.
• Avoiding roof penetration is crucial for preventing leaks in metal roofs.
• Tile roofs need careful handling to maintain water tightness.
• Choose a reputable installer for quality assurance and adherence to warranty terms.
• Consider the quality of installation components for long-term system efficiency.

It might cost more upfront, but paying a little extra to buy from a good, knowing installer can avoid a costly repair (or worse) further down the line, and result in high quality, durable solar power systems for your home.
