Studies show that solar panels installed on rooftops do better in hot climates than in cold ones. Why? A rooftop’s local climate varies vastly from one area to the next inside the same climate zone.
For example, two rooftops in the same hot climate face different conditions due to their different orientations to the sun and surrounding local terrain.
Is it time to add solar panels and fast-track your business tax deductions in the new year? If so, listen closely and our tips for finding the best roof for a solar panel installation.
Best Roofing Materials for Solar Installation
When deciding on the best type of roof for a solar panel installation, the most important factors to consider are the overall structural integrity of the roof, the amount of unobstructed sunlight received, and the types of materials used to construct the roof. The best type of roof for a solar panel installation depends on the homeowner and their goals. Here are some examples that you should consider:
Asphalt Shingles
Asphalt shingle roofs are affordable, easy to install, and a great choice for any budget. They come in various styles and colors, giving homeowners options to choose what will fit their home aesthetic best.
These roofs are highly durable; made from asphalt and fiberglass, they will handle extreme weather conditions with ease and will last for decades, saving the homeowner money in the long run. Not only that, but the durability of asphalt shingles can also help protect any solar panel installation that may be installed on the roof, providing an extra layer of protection.
Metal
Metal is considered one of the best types of roofs for solar panel installation. Metal roofs are renowned for their strength and longevity, far outlasting other materials such as asphalt shingles. They are also highly reflective, which helps to say a large part of the sun’s energy away from the solar panel installation.
Tiles
Tile roofs are also extremely durable and can last for more than 50 years. In addition, tile roofs allow for easy installation of solar paneling, which makes them ideal for the job. The interlocking slate of tiles also prevents water leaks, making sure the solar panels are not damaged.
Tiles have a low profile, which makes them neat and attractive in a home. They are one of the best options available, offering strength, durability, and compatibility.
Tar and Gravel
These roofs are strong and durable and can withstand a lot of weight from solar panels. This roof is also known to be one of the most cost-effective since the materials are not expensive. They are relatively easy to install and support, providing efficiency and durability.
Tar and gravel roofs give the greatest protection against moisture, reducing energy losses and helping to prolong the life of the solar system. They also provide excellent protection against extreme temperatures and UV rays, which can damage most solar panel installations. Tar and gravel roofs are fire resistant and can also provide extra insulation and ventilation, which can extend the life of the solar equipment and keep the system running efficiently.
Roof Pitch
In general, a flat or low-sloping roof is best for optimal efficiency and performance, as sloped roofs produce shadows that can inhibit energy production. Solar panels should be positioned to avoid these shadows; since flat roofs can be easily manipulated or installed with non-penetrating racks, they are great for avoiding shadows.
Roof Orientation
Generally, south-facing roofs that are free of any overhangs or trees give the best orientation for solar energy production. Sloped roofs made of asphalt shingles give a great surface for mounting the best solar panels.
Flat roofs are often used for commercial installations and must mounting rack systems that take up more space. Metal and tile roofs are also good materials for solar panel installations.
Most residential roofs are likely to have at least a pitch of 3/12 and must be trimmed around the edges to make sure that rainwater can run off. A roof with a pitch greater than 8/12 is not recommended for a solar panel installation as it can be unsustainable and may spring leaks.
Size of Your Roof
If you have a large roof, you can opt for a tile roof, which provides an ideal surface for installing solar panels along with a range of different roofing styles. Tile roofs are also easy to support and can last for up to 60 years. On the other hand, if you have a small roof, a flat roof is the best choice, as it maximizes the efficiency of the solar panels and can be easily cleaned.
Shading on Your Roof
If there is minimal shading from trees, chimneys, or nearby structures, a metal roof is ideal since it is durable, lightweight, and reflects sun rays. Metal roofs can be noisy when it rains.
If there is more consistent shading, a tile roof may be a better choice since it absorbs more heat and can increase the efficiency of the system. Tile roofs are aesthetically pleasing and will last for years with minimal maintenance.
