Solar power is now more accessible than ever. The cost of solar panels has dropped thanks to technological advancements. Many homeowners currently lease their meetings, which reduces their energy costs and eliminates their financial responsibility.
GTM Research and Solar Energy Industries Association found that 2013’s third quarter was the most successful for photovoltaic (PV), or solar, installations. The fact that homeowners appreciate this:
- Utility companies pay homeowners to generate excess energy. They credit future energy bills.
- Solar power is the critical component of sustainable homes and developments that strive to achieve net-zero or Passive House standards.
- A PV system can earn LEED points, directly and indirectly, depending on how much of the building’s total energy use it will offset. This point increases with the addition of cool metal roofing.
- Appraisal Journal reports that every $1 saved by a solar energy system in a home increases its value by $20
These are just a few of the many benefits PV systems offer, but there is another. Roof-mounted solar electric systems are only as practical and cost-effective if installed on a quality roof.
Roof quality is essential when installing solar panels.
A roof that isn’t in its best condition can be used to build a solar system. It’s only a matter of time before the home’s structure will be compromised, and the entire foundation-structural unit will require severe repairs and replacement. If you plan to move a home’s electricity system to a solar array, steel, and metallic roofing options are the best choices.
The solar panels are on racks that withstand strong winds and extreme rain or snow. It is sensible to place them on a roof that can withstand the same conditions, has a similar warranty, and has a similar lifetime. However, most American homes are made with asphalt or composition shingles.
There are better foundations for a solar system. This is especially true if it is retrofitted on a roof older than seven years. Roofs older than seven years are at risk of falling before the solar panel racks. Combining the cost of a roof replacement or renovation with labor costs to remove and reinstall the solar shelves can lead to a hefty bill.
Metal roofs work best with PV systems.
These are just a few of the reasons metal roofs are the best medium to produce a photovoltaic system.
They offer a better warranty match. Solar panels have a life expectancy of 20-25 years. Although long-lasting asphalt shingles may have a warranty of up to 20 years, this warranty is often void because it does not cover extreme weather conditions like hurricanes and high winds. They don’t typically cover labor costs for repairs or replacements. Additionally, significant maintenance and shingle replacements could require deconstruction and reinstallation of the array.
Metal roofs are pre-engineered to suit the climate and needs of your building. They are usually as long as 40 years. Your roof will last longer than the solar panels. This eliminates the need to remove and reinstall solar racks or panels until they are replaced.
A standing seam metal roof can be easily fitted with racks. A standing seam metal roof is also known as a concealed fastener roof. The fasteners are hidden under the roof panels, which homeowners love. This roof is compatible with solar racks that offer fasteners that attach directly to the standing seams. Hidden metal roofs with rack locks that attach to the seams prevent water leakage or premature wear.
Laminates can also be installed on metal roofing. Laminates, thin-film solar panels adhered to roof surfaces by an adhesive backing, are another option. They don’t produce the same amount of electricity as crystalline panels, but they can offset electricity consumption in sunny areas and homes with a lot of southwest exposure. These systems might use a lighter rack system rather than adhesives. They can also be attached directly to the metal roof.
Additional benefits of metal roofs
Metal roofs are an excellent option for eco-conscious homeowners who want to make their homes more sustainable.
Additional energy savings. Energy.gov states that heating and cooling account for over half of household energy costs. Cool metal roofs can lower cooling costs by up to 40%. Cool roofs have a reflective coating to reflect UV rays back into the atmosphere. Combining this reflective property with the emissive nature of a metal roof, households can enjoy significant energy savings and reduced solar gain, particularly when paired with a solar power source.
Extreme weather resistance Metal roofs can withstand strong winds, heavy snow and ice loads, and hurricane-force winds. GALVALUME is a special protective coating that makes metal roofs virtually impervious to water and UV rays. It also protects against environmental toxins specific to each location. Metal roof manufacturers are happy to offer up to 40 years of warranty because of this durability.
They are a great help in green building certification. Installing a cool metal roof can help you earn LEED points. However, that’s just one program that recognizes the environmental advantages of metal roofing products. Metal roofs can also help you get green building certifications, such as the National Association of Home Builders, Home Innovation National Green Building Standard, and ENERGY STAR.
Have a positive impact on your life. The most sustainable materials available are steel and metal building products. They are made with a high percentage of pre- or post-consumer material and are 100% recyclable. This is in addition to the fact that metal roofs can last up to 50-70 years or more.
Before you go full speed ahead with your solar power installation, ensure that your home’s roof is in good condition. Installing a metal roof is a good idea for building a new home. It is worth replacing your old roofing material if it is over ten years old.
