Have you considered putting solar panels on a metal roof? It’s not surprising that installing solar on metal roofs is becoming a more common topic among homeowners given that metal roofs are lightweight, strong, and frequently built of recycled materials that are environmentally good. The good news is that metal is one of the best roof materials for solar panels if you fall into this group. Let’s discuss it deeply below.

Can You Put Solar Panels on A Metal Roof?
Of course Yes. Metal roofing is resistant to severe weather conditions, lightweight, and long-lasting.

Why Metal Roofs Are Suitable for Solar Panel Installation?
The fact that metal roofs are made from recycled materials is a compelling argument in favor of choosing them over other types. Utilizing metal roofs will help you encourage environmental sustainability because you’ll be able to use recycled materials more frequently, which will reduce pollution.
- Solar Panel Type Flexibility
Thin-film photovoltaic panels and silicon photovoltaic panels are the two different types of PV solar panels. While thin-film photovoltaic panels are flexible, silicon panels are larger and more rigid. Both types of solar panels can be installed on metal roofs, giving you a variety of options. On top of these, metal roofing can also benefit from solar laminates. PV solar laminates are available as strips that stick to the metal roof surface, providing yet another method for capturing solar energy.
The life expectancy of your investment will greatly influence the results when considering solar energy. Solar PV panels last for 25 to 30 years. The life expectancy of your roof type must be greater than that of the PV panels you plan to use in order for you to produce solar energy at levels that are cost-effective.
Metal roofs provide the level of durability required to produce solar energy efficiently. A 2014 Metal Construction Association study found that metal roofs can last for 60 years. By choosing metal roofs, you can prevent the long-term cost of your pursuit of renewable energy from costing you an arm and a leg because you will eventually need to replace your roof material.
- Energy Efficiency
Your home stays cool in the summer thanks to metal roofs that have reflective paint coatings. A further way to reduce the energy required to control indoor temperature is to install solar panels on metal roofs that already have this paint coating. You can therefore achieve higher levels of energy efficiency and the resulting cost savings by combining metal roofs and solar panels.
- Adaptable to Strong Winds
In contrast to other roofing materials, metal roofs hold up well in strong winds. Make sure the brackets you use to fasten your solar panels are installed correctly and securely. A seal must be created between the brackets and the metal sheets in order to properly secure solar panels using brackets. This is done through the highest point in the metal roofing. With such a setup, the solar panels are safely anchored to the metal roof and can take advantage of the metal roof’s wind resistance.
Types of Metal Roof
Metal roofs are popular for homes, commercial buildings, and new constructions, so they frequently have irregular shapes and no set design.
For each type of metal roof, there is a dependable installation technique and bracketing system.
Standing Seam Metal Roof
A continuous, concealed join is created by crimping a series of flat, wide metal panels together to create this type of roof. Between each one, there is a vertical leg; this is the raised seam.
When installed sequentially with the suggested underlayment, this type of roof is not only strong and lightweight but is also waterproof.
Corrugated Metal Roof
Solar panels cannot be installed onto a corrugated metal roof without drilling holes; every precaution is taken to keep them watertight.
It needs a unique mounting setup that makes use of straddle block brackets. They firmly adhere to the top ridge, leaving the lower crest, where the rain gathers, without any holes. The holes in high-quality brackets are sealed with thick rubber gaskets, which are more effective and less messy than using sealant gum.
Metal Tile Roofs
Another approach to mounting solar panels that don’t involve drilling holes or breaking through metal For typical asphalt tile roofs, there is also a comparable system.
Pre-attached metal tiles are on the mounting rail. Aligning them with already-placed tiles and exchanging them is a straightforward process. The panel attachment is simple and the unit clicks into place with the aid of guiding metal rods.
Since the new tiles are identical in shape to the old ones, neither an eyesore nor unwelcome gaps for moisture to enter are produced.
For the roof, they provide organic protection that keeps it in good shape.
What Kind of Roof Is The Best for Solar Installation?
In a technical sense, any roof is suitable for installing solar panels. The extra cost incurred as the degree of installation difficulty rises is what distinguishes some roofs as a bad choice.
Some jurisdictions consider wood shake roofs to be fire hazards, but once you have the go-ahead, you will need to use flashing to allow for the mounting of solar panels. Make a watertight seal by drilling the flashing deeply into the wood shake.
Using an unapproved sealant by the manufacturer during the installation of asphalt composite shingles could void the roofing warranty. Additionally, you need to use a flash with a raised platform so that water can be diverted away from the area where the penetration occurs. The best way to use the flashing to prevent poor drainage will depend in part on the thickness of the shingle.
Undoubtedly, the hardest roofs to install solar panels on are those with clay or stone tiles. Since the tiles must be taken out in order to install the flashing and mounts, this is the main cause of the difficulty. After this is completed, the tiles must be cut to prevent contact with the mounting equipment. An installation that is both expensive and difficult results from all this extra work.
The simplest type of roof for solar panel installation is a standing-seam metal roof, as clamps can be installed on the seams to create a base for the racking that will support the solar panels.
Solar power is a reliable and inexpensive energy source, but it needs solar panels installed in order to produce electricity. Consider all the needs in order to comprehend how to increase the energy efficiency of your home or place of business.
