No pre-drilling, just drive the lag home. Drilling a hole first is not necessary, and reduces holding strength. No reason to make a science project out of it and increase cost and labor.</font></div><div><font face="verdana, geneva" size="2"><br></font></div><div><font face="verdana, geneva" size="2">Mark</font></div>

Hi Jay, <br><br> There is no room for flashings. The L feet will go very close to the skylights and the flashing would hit the edge of them. Plus there is an existing array that was done by another installer that is done with L feet only. The new array would be higher. <br><br> <br> <blockquote type="cite" class="cite" cite="">And given that we have really good off the shelf approved flashed feet, why would you use anything else?<br><br> My 2 cents,<br><br> Jay<br><br> peltz power<br><br> <br> On Jun 29, 2012, at 5:16 AM, Glenn Burt wrote:<br><br> <blockquote type="cite" class="cite" cite="">We have used a variety of sealants over the years, and determined simple Henry roofing cement is the best product for use on comp roofing.<br> <br> We also used to bend our own L-foot flashing, which we cut from standard Al coil stock (before all the manufactured options were available).

Would it be completely crazy to follow suit of the existing array and bolt L feet straight to the shingle roof with good roof sealant?
