image002cropAre you considering putting Solar on your roof?

  • Consider these questions before buying a solar system
  • How old is you roof?
  • Is your roof flat or is it pitched?
  • What type of material is your roof made of?
  • If it is flat, does it have “rock” on it or is it a “cap sheet”?
  • If it is pitched does is have: composition shingles, concrete tile or clay tile?

The answers to the above questions all have a great deal to do with whether or not your roof is a good candidate for solar installation. These questions can only be answered by expert roofing professionals. The mounts that hold the solar system on to your roof are considered “penetrations” just like pipes and vents that are on your existing roof. The only way to guarantee that those “penetrations” are waterproof is to follow the roofing material manufacturers installation instructions. These are very specific and each different type of material has a different type of flashing needed to make the penetrations waterproof long term.

The big warning here is that most solar companies are attempting to use non-approved, third-party quick fix flashing solutions. These are not approved by your roofing material manufacturer or supported by any roofing industry standards. They are also using employees to install these third-party systems, instead of the proper course of action which is to have a roofing professional install the proper flashings. This is done solely to move faster and cut corners.


These are the steps you need to take to install a solar system on your home:

  1. Have your roof inspecting by a professional roofing contractor.
  2. Be prepared that if your roof is not sufficient to support a 30 year solar system, it is in your best interest to re-roof before putting up a solar system. *current guidelines allow you to write off up to 30% of the cost of the roof that is related to solar*
  3. Insist that the stantions used to support your new solar system are flashed in place by a professional roofing contractor, not the solar company and require your solar company to add that to your solar contract. That way if your roof leaks after your solar system is installed you have a licensed professional available to remedy the issue correctly.
  4. If your house has been re-roofed within the last ten years, contract your roofing professional and request assistance before installing solar.
  5. Just because your solar contractor says your roof is “ok” and they can “flash in the stantions and save you money” doesn’t make it so, see step #1
  6. Leaks related to solar installation are not covered under pre-existing roof warranties or is the damage resulting from solar installation.
  7. Many companies are now leasing solar systems, they will tell you they will come back at a later date and remove your panels if there is an issue. Many of these companies are then bought and sold by other companies that may not cooperate with your original arrangement. Save yourself the grief, do it right the first time!


You can do a roof without solar, but you can’t do a solar without a roof! (unless you do a ground mount system)
