Do solar panels put holes in your roof?
When solar panels are installed, installers will drill holes into the roof to anchor and mount the panels securely. These large holes are for lag bolts, which are strong enough to keep solar panels in place and are made to withstand the elements for a long time.
Why you shouldn’t put solar panels on your roof?
Your roof is too small: Solar panels need sunlight to generate electricity. The more sunlight they absorb, the more power they generate. If you have a small roof, you may find that solar panels simply won’t generate enough kilowatt—hours to make a real impact on your bills.
What happens when you need a new roof with solar panels?
If it’s determined that your roof should be replaced prior to going solar, it’s a smart move to do so. Solar panels are more durable than most roofing materials. As a result, when you pair solar with a roof replacement, the panels actually extend the lifetime of the portion of the roof that they cover.

How long do solar panels last on your roof?
The average lifespan of solar panels is 25 years. However, this doesn’t mean the panels on your roof will stop producing electricity after a couple of decades. It just means that after that point, their energy production may decrease beyond what solar panel manufacturers will guarantee their rated production output.
How many years does a roof last?
Slate, copper and tile roofs can last more than 50 years. Homeowners with wood shake roofs should expect them to last about 30 years, while fiber cement shingles last about 25 years and asphalt shingle/composition roofs last about 20 years, the NAHB found.

Solar panels block rain and protect the roof from years of consistent sunlight. Though, unless you plan to get solar powered roofing tiles (photovoltaic shingles), solar panels are not a replacement for your roof . Photovoltaic shingles are known as “BIPV” or Building Integrated Photovoltaic tiles. The Solar Timeline Explained
