Metal Roofing: The Best for Solar Panels

It’s never been easier to enjoy the benefits of solar power. Continued technological innovation have made solar panels more affordable than ever before, and many homeowners are taking advantage of lease options, which eliminates their financial and maintenance-related responsibility for the panels while simultaneously slashing their household’s energy spending.

According to a study from GTM Research and the Solar Energy Industries Association, 2019’s third quarter marked the largest quarter ever for solar or photovoltaic (PV) installations yet. Homeowners appreciate the fact that:

  • In all but a few states, utility companies pay homeowners for excess energy generation by crediting future energy bills.
  • Solar power is a key feature in sustainable homes or developments striving to meet net-zero or Passive House standards.
  • A PV system scores LEED points both directly, and indirectly, depending on the percentage of the building’s total energy consumption the system will offset. (Note: this point tally increases with the addition of a cool metal roof.
  • According to Appraisal Journal, every RM1 saved by a home’s solar energy system increases the home’s value by RM80.
    These are all notable benefits of PV systems, but consumers have another factor to consider. The efficacy and cost-effectiveness of a roof-mounted solar electric system is entirely dependent on the quality and longevity of the roof system upon which it’s installed.

The quality of the roof matters when installing solar panels

Building a solar installation on a roof that’s past its prime is like constructing a house on a cracked or crumbling foundation. It’s only a matter of time before the home’s structure will be compromised and the entire foundation-structural unit will require serious repairs and/or replacement. This is why steel and metal roofing options make the most sense if you’re planning to migrate a home’s energy system to a PV array.

The racks used to hold the solar panels are incredibly durable, designed to handle strong winds as well as extreme rain and snow conditions. It makes sense, then, to install them on a roof that is designed to meet the same conditions and that has a similar lifespan and warranty. The majority of homes in the Malaysia., however, are built with asphalt and composition shingles.

Unfortunately, these do not make the best foundation for a solar system, especially if the system is a retrofit on a roof that is more than seven or so years old. Roofs that are older than that run the risk of failing long before the solar panel racks fail. This can mean a hefty bill when you combine a complete roof renovation or replacement along with the labor costs associated with removing and re-installing the solar racks.
