| Question About Securing A 4 X 10 Panel To A Shingled Roof I have a 4 by 10 foot domestic hot water solar panel that I wish to mount to my roof, I contacted the company who manufactured the panel to find out about buying a mounting kit and their advice was let the “solar” installer decide on how to make a mounting, which they advised is most commonly done with Unistrut, which allows the panel to be angled for maximum efficiency.
I have two problems with that, first I don’t want to have some kind a galvanized Unistrut assembly crapping up the look of the roof and two I only want the panel to be raised above the roof by about 2 inches or so and I want it to be on the same angle as the roof.
Now I understand that angle may not be the best for efficiency, but I am already up to my wazoo getting this past the wife and the HOA, so for this job aesthetics shall prevail over efficiency.
None the less my plan is to fabricate 8 two inch wide mounting brackets out of 4 by 4 inch 6061-T6 aluminum angle which I will finish to match the panel and fasten those brackets to the roof with two 3/6 inch by 3 inch stainless lags and then fasten the brackets to the aluminum frame of the DHW panel with three ¼ inch TEK’s.
My question is, should I put something, anything or nothing between the base of the brackets and the shingles to ensure a leak-proof installation, because if I screw up the roof and it leaks, my wife having written the check for the new roof will feed me to the fishes. |

Or do you mean 3/4" TEKs...?? |

1/4" by 1/2" long. |

Let me ask you a question, I have a tool for blind rivets, might 1/4 inch rivets be a better choice?
I realize I am dealing with a shear force and I would have to drill them out if I needed to remove the panel, but unlike TEK's rivets would not be not relying on a course thread to hold them in place. |

Since you are dealing with sheer and not pull out force, the screws will do much better. Those blind rivets (a.k.a. pop rivets) are not really very strong. |
