  • Roof mounting.

    I picked up some panels, did about 2 weeks worth of research, Drew out the plans and am feeling confident in handling this project. I have one concern though.... I have flat tile roofing and ideally would like to avoid putting holes in them. What is the best way to secure the panels on a sloped flat tile roof? I live in California in an area where the winds can pick up a bit in the afternoon.

    Thanks.

    Edit: This is for pool solar heating.

      Not a good idea to drill holes in a rigid (concrete, clay, etc.) tile.
      Not recommending this at all, but if of the flexible type (Fafco, etc.), many folks simply lay the collectors on the roof and call it done, seemingly using the rigidity of the piping to hold everything in place. They often later watch the collector shift around or blow off in the wind.
      PV fasteners like "S" hooks or other such devices might be useable and adaptable as a base for a frame.
      Double flashing for support/anchor points like commonly done for other roof penetrations is one safe way.
      Avoid putting combustible materials (wood) on a roof. First off, it's unsafe. Second , CA fire codes do not allow it.
      Whatever you do, and whoever does it, it will still require code conformance, including wind.
      See a site called builditsolar.com for some ideas.

      If it was me, I'd build a support frame and use double flashing on the penetrations. Or better yet, keep it off the roof entirely and use a ground mount, but only after I installed an effective pool cover.

        You have a couple options.
        SolarRoofHook: https://www.solarroofhook.com/solar-...-roof-products
        QuickMount tile replacement: http://www.quickmountpv.com/products...unt.html?cur=1

        QuickMount also has options to cut holes. They come with double flashing, so they are still reliable, but a lot of work.

          The solar roof hooks seem like they'd be more than adequate to keep the panels secure. I imagine you'd just drill into the stud with some kind of sealant, replace tile and secure to panel?

          Any other measures I should take to ensure the integrity of my roof stays in tact? I've never done anything like this, but am fairly handy when needed.

            OK, this is for solar pool collectors right? - Companies like Aquatherm just lay the flexible plastic type collectors on the roof and secure the corners in place with little straps that are tacked to the roof. Could be anchored under the tile.

                Not sure why the forum is deleting most of my post.

                        Maybe just as well if you're posting to a 15 month old thread.
