Flashing / sealing

I have an AET solar panel to install with a standard mount kit. What is the best way to seal the mounts on my shingle roof to avoid leaks through the bolts holes ?

Also, I purchased a coolie cap pair for the copper pipes. I assume this goes under the shingles, like regular flashing ?

Brian, use either a good roof sealant  or lapseal,  both come in regular tubes like caulking or use silicone if you have colored shingles. Caulk inside the hole before you insert your lag bolt and under the mount also.... apply to the piping around the hole and under the copper flashing also

Okay, thanks. And the copper flashing on the coolie cap does go under the shingles, right ?

yes. those caps are small , so tuck the top under the shingle as best you can. doesn't hurt to seal around all edges of the copper cap either. I usually solder the cap directly to the pipe also.
