Metal roofing is a popular choice for many homeowners and businesses, thanks to its many benefits. Some of the advantages of metal roofing include:
- Longevity: Metal roofs can last 40 to 70 years, compared to 12 to 20 years for asphalt shingles.
- Durability: Metal roofs are resistant to fire, mildew, insects, and rot. They can also withstand high winds, hail, and snow.
- Energy efficiency: Metal roofs reflect solar heat, reducing cooling costs in summer. They can also be insulated easily, improving heating efficiency in winter.
- Lightweight: Metal roofs are much lighter than concrete tiles or slate, reducing the stress on the roof structure and making installation easier.
- Environmentally friendly: Metal roofs are made from recycled materials and can be recycled again at the end of their life. They also pair well with solar panels, reducing greenhouse gas emissions.
But how do you install solar panels on a metal roof? Is it possible? Is it safe? Is it expensive?
In this blog post, we will answer these questions and more. We will also share some tips and best practices for installing solar panels on a metal roof.
Understanding Solar Panel Installation on Metal Roofs
Can You Install Solar Panels on a Metal Roof?
The short answer is yes, you can install solar panels on a metal roof. In fact, metal roofs are very compatible with solar panels, thanks to the variety of solar panel mounting systems available in today’s market.
A mounting system is a device that allows you to attach solar panels to your roof, safely and securely. There are different types of mounting systems for different types of metal roofs, such as:
- Corrugated metal roofs: These are common on industrial and commercial buildings. They have ridges and valleys that create air gaps between the roof and the panels. To install solar panels on a corrugated metal roof, you need a mini rail system that is drilled onto the ridges of the roof via self-tapping screws. This keeps the panels close to the roof, minimising wind impact and bird nesting. The clamps have a rubber backing and sealant to make the system waterproof.
- Standing seam metal roofs: These are popular on residential and commercial buildings. They have vertical seams that run from the ridge to the eave of the roof. To install solar panels on a standing seam metal roof, you need a seam clamp system that attaches to the seams without any drilling or penetration. This preserves the integrity of the roof and prevents leaks. The clamps have bolts that secure the panels to the roof.
- Flat metal roofs: These are rare on residential buildings but common on commercial ones. They have no slope or pitch and require special drainage systems to prevent water accumulation. To install solar panels on a flat metal roof, you need a ballasted system that uses weights or blocks to hold down the panels without any drilling or penetration. This avoids damaging the roof membrane and creating leaks. The ballasted system also allows you to tilt the panels at an optimal angle for maximum sun exposure.
What Are the Benefits of Installing Solar Panels on a Metal Roof?
Installing solar panels on a metal roof has many benefits, such as:
- Saving money: Solar panels can reduce your electricity bills by generating clean energy from the sun. They can also increase your property value and qualify you for tax credits and incentives.
- Saving time: Solar panels can be installed faster and easier on a metal roof than on other types of roofs, thanks to the lightweight and compatible mounting systems.
- Saving space: Solar panels can be installed closer to the roof surface on a metal roof than on other types of roofs, thanks to the low-profile mounting systems. This saves space and improves aesthetics.
- Saving maintenance: Solar panels require little to no maintenance once installed, especially on a metal roof that is also durable and easy to upkeep.
What Are the Challenges of Installing Solar Panels on a Metal Roof?
Installing solar panels on a metal roof also has some challenges, such as:
- Cost: Solar panels are still an expensive investment upfront, even though they pay off in the long run. The cost of solar panels depends on many factors, such as size, quality, location, and installation.
- Warranty: Installing solar panels on any type of roof can potentially void your roof warranty if not done properly or by an authorised contractor. You should always check your manufacturer warranty before installing solar panels on your roof.
- Aesthetics: Solar panels can alter the appearance of your roof, which may or may not suit your personal taste or your neighbourhood’s style. You should always consider the visual impact of solar panels on your roof and choose a design that matches your preferences.
