What typical structural changes are required to a home's roof to install solar panels?

For the vast majority of roofs in Victoria, solar panel installations won’t require any major structural changes.

Most roofs today are more than adequate to handle the extra load of a solar power system. This includes not just the weight, but the strength to withstand lift. Lift is when the wind gets underneath the solar panels and creates upward pressure. Since a roof must be able to support the racking, panels, snow and/or ice in the winter, and lift, roof trusses may need reinforcing in some cases.

Of course, if there are any weakened or damaged areas on your roof, these will need to be repaired before an installation can proceed as well. 

An additional thing to be aware of is that solar power systems last 30 years and more, whereas a shingled roof generally has a lifespan of 25 years. If your roof is close to needing replacement, you may want to have that done beforehand. At the same time, it may be worth considering switching to a metal roof. Metal roof lifespans are typically 50-100 years, meaning you are not likely have to replace your roof over the entire lifespan of your solar panel installation

Fortunately, there’s no need for you to determine how strong your roof is. As part of their initial assessment, solar energy installation professionals perform an evaluation of your roof's structural soundness. In the event changes are needed, they’ll let you know. Once building code requirements are met, permits will be issued and work will begin!
