The majority of homeowners interested in residential solar panels will opt for a rooftop installation. In most cases, the amount of space and the logistics required for a ground installation aren’t well-suited for typical solar panel projects. However, those interested in adopting solar power in Calgary will face a pressing question as they proceed. Is your roofing material capable of supporting solar panels? What challenges might you encounter?
Before delving into the different materials, let’s address a common question: will you need a new roof?
Do You Have to Replace Roofing Before Installing Solar Panels?
Installing roof-mounted solar panels requires weighing your immediate needs with the future. While some roofing materials have an extended lifespan, others require more frequent replacement. In areas with harsh weather, the lifetime of some roofing materials tends to be shorter. Consider that replacing a roof after installing solar panels requires extra steps to remove and re-install your system adequately.
With that in mind, some companies specializing in solar installation in Calgary will suggest replacing your roof before installation. This recommendation results from evaluating several factors. These aspects usually include the type of roofing material, the location of the home, and the current age or condition of a roof. It is in a homeowner’s best interest to avoid the hassle of installing residential solar panels in Calgary only to be forced to replace the roof five or fewer years later.
That does not mean you will always need to replace your roof. Instead, prepare to discuss it with your installation team. Doing so can help you chart the right course for making an astute investment with long-term benefits.
Installing Solar on Different Types of Roofing Materials
Homes around the Calgary area often use a variety of roofing materials. Homeowner preference, a developer’s choice, or the age of the building can all affect the type of roof a building may have. Today’s installation techniques make it possible to adapt solar panel hardware to suit a rich assortment of roofing materials. However, some will provide a more effortless experience than others. Let’s examine a few of the primary types we encounter.
Asphalt shingles
Asphalt is a prevalent roofing material across home styles. It is popular for its relatively fast installation time and its durability. In ideal conditions, an asphalt shingle roof may last for as long as 30 years before it requires replacement. In natural conditions, it may not last as long. However, its longevity and durability make it suitable for solar installations. Installation does not compromise the shingles because panel mounting hardware only needs to penetrate the roofing studs or deck. Waterproofing around these connections keeps the roof from springing leaks.
Cedar roofing
Cedar roofing is popular because it can last for decades with appropriate maintenance. Achieving the full lifespan does require care and attention. However, its durability does make it a good contender for installing solar panels. Much like asphalt shingles, the process involves mounting hardware to roof studs and installing waterproof flashing around each mount. However, installation activities could potentially damage or crack wood shingles. Extra care is critical, but the difficulty level is similar to asphalt.
Metal roofing
Metal roofing is increasingly popular due to its notable durability and long life. Some styles of metal roofing installation lend themselves naturally to solar panel installation. Sometimes, you may not need installers to drill holes, but you can clamp directly to the roof’s seams. In other cases, drilling cannot be avoided. However, since it is through straight metal, there is less chance of damage to the surrounding area, and waterproofing remains simple. Metal roofs can often support heavier loads, which may further make them an ideal medium for solar panels.
Clay tiling
Clay tiles are an attractive aesthetic choice for some homeowners. However, they do present a more challenging environment for solar panel installation. Clay tiles can be fragile, which often means a risk of damage and the need for tile replacement. Installers also cannot affix panels or mounts directly to these tiles. Instead, the temporary removal of tiles is necessary to facilitate the installation of hardware on the roof, enabling it to bear the load and distribute the weight. After installation, tiles can be replaced around the area—always choose an experienced installer if you have a clay roof.
Finding Support and Learning More About Next Steps
With modern installation techniques and hardware, solar panels suit virtually any of the most common roofs. However, as we’ve seen, some materials can have unique concerns. Also, older roofing installations may create additional problems to navigate before installation.
