How do I install Solar on a Foam Roof?
Hi All-
I have a foam roof and am interested in installing solar panels. Can someone describe what will need to be done to do this?
Thanks, Lynn
Hello Lynn,
Most people these days are considering PV solar (although what I am about to tell you would apply to standard solar insallations to some degree).
Here are some simple steps:
1. Make sure your foam roof is in good condition and have it recoated. You won't be able to access the roof under the panels once they are installed. It's very important that your roof lasts longer than your solar system....you don't want to have to remove your solar system to replace a leaking roof.
Your roof will be cleaned before recoating. It is at this point that you will want to install the legs or stand-offs that will support your solar panel rack. Installation of the stand-offs is pretty straight forward but this work must be coordinated between your solar and roofing contractors.
Each stand-off should be carefully sealed into the roof to avoid future leaks. If only a few stand-offs are needed, workmen may be able to seal in the stand-offs with urethane sealant. This work is relatively inexpensive. If there are a lot of stand-offs then at some point it makes more sense to take out a foam truck and spray in the new roof penetrations. Definitely discuss your options and potential costs prior to cutting holes in your roof.
2. Install your solar system and start saving money and the planet (and be the envy of your neighbors).
There you have it. How to install a solar system in 2 simple steps. I could have just said to have your solar contractor talk to your roofing contractor but I'm sure you were already planning on doing that.
Please call with any specific questions. I speak somewhat better than I type.

Hi Adam- Thanks for your reply. It makes sense to me since I already have a foam roof.
To be honest, Palo Alto's energy costs are pretty low compared with PG &E so the payback time for solar is a long long time. That isn't the main reason for doing it however (if you can afford it). Palo Alto offers a "Palo Alto Green" energy option which allows you to buy energy from Green energy sources (i.e. wind). Seems like this is the way to go for Palo Altans who want to reach a "carbon neutral" goal.
