Does Installing Solar Panels Affect My Roof Warranty

So, weve established that as long as theyre installed correctly solar panels can actually have a beneficial effect on your roof, but you may still be wondering about whether installing solar panels could void your roofs warranty. That is an important thing to consider.

The answer is simple in some cases. Mounting systems that do not penetrate your roof, which includes ballasted racking and roof clamp racking, will not have an effect on your roofs warranty. For penetrating systems, you should take a couple important steps in order to make sure you dont void your roofs warranty:

  • Talk to Your Roofer: You should inform your original roofing contractor of your plans to install solar panels and ask about whether this will have any impact on your warranty. In some cases, to protect your warranty, you may need your roofer to prepare your roof for the installation process by removing shingles or tiles where mounts will go. This will require your roofer to coordinate with the contractor installing your panels.
  • Hire a Qualified Contractor: Even if your roofer helps to prep your roof, it is still vital that contractors installing your solar panels have the experience and expertise to do a quality job and avoid damaging your roof in any way. Even denting your roof slightly could void your warranty since this can have a long-term effect on your roofs effectiveness. Ask your contracting company if it can guarantee your roof wont be damaged, keeping your warranty intact.

What Kind Of Roof Materials Are There And How Are They Different For Mounting Solar Panels

If you have a house in Australia, you probably have either a tile roof, a slate or shingle roof, or a corrugated metal roof. Tiles are hard and held together by a combination of mounting hooks and gravitylike a jigsaw puzzle. It is possible to take broken tiles out to replace them, sometimes without any special tools. Shingles and slates, on the other hand, typically have holes in them and are nailed onto the roof substrate. In both cases, they overlap each other so that water does not penetrate the building as rain falls. Corrugated metal roofs are composed of comparably large sheets that usually overlap each other, or may be one large piece. In mounting a PV system on any of these types of roofs, it is important to ensure that no gaps are left in the roof that may later result in leakage.

Mounting a solar array on all of the above types of roof is possible and in fact quite standard practice for solar power system installers, as many installations are retrofit onto the roofs of old homes.

What About My Roof Pitch

Although it is a less significant factor than azimuth, the angle or pitch of a roof should also be considered. For a roof in the Northeast, because of the suns position through the year, the ideal angle for maximum electricity production on a South-facing roof is 36 degrees. However, almost any angle can work, even a flat roof. Again, the difference is your level of production.

In fact, a steeper roof is not always better for solar. For example, if you put solar on a West facing roof a lower pitch is better because more morning sun reaches over the peak than with a higher pitch. Thats why I noted above that even a North facing roof could work if it was nearly flat.

And for those craving more detail on pitch and to talk the talk of construction experts heres how angles translate into roof pitch:
