Most solar contractors receive public funds (rebate monies, ARRA program distributions, etc.). Some of those companies are installing systems in a manner that is not building code compliant. It just takes a high profile leaky roof at a VA hospital or a public housing project where a solar system was installed in a manner that does not meet the building code to lose years of goodwill and support for the industry. </font><span class="Apple-style-span" style="font-family: Calibri; font-size: 13px; ">Modules prices have fallen quite a bit, but we all loose if State and Federal or public (opinion) support for the industry goes away. </span></div><div><span class="Apple-style-span" style="font-family: Calibri; font-size: 13px; "><br></span></div><div><font class="Apple-style-span" face="Calibri"><span class="Apple-style-span" style="font-size: 13px;">Obviously, that's the worst case scenario: That somehow the industry gets painted as being made up of a bunch of irresponsible, fly-by-night, subsidy chasers.

When they do, which side of the curve will your company be on?

<div id="SafeStyles1341372106">
<div><span style="font-size: 13px; font-family: Cambria;">+1 on the use of structural screws. We ran an article about lag screws a couple years ago:</span></div>
<div><span style="font-size: 13px; font-family: Cambria;"><br></span></div>
<div><a href="http://solarprofessional.com/article/?file=SP3_4_pg70_Shelly"><span style="font-size: 13px; font-family: Cambria;">http://solarprofessional.com/article/?file=SP3_4_pg70_Shelly</span></a></div>
<div><span style="font-size: 13px; font-family: Cambria;"><br></span></div>
<div><span style="font-size: 13px; font-family: Cambria;">One of the things that surprised me when I read this manuscript is how variable lag screws are in terms of construction and quality. Besides the convenience of being able to drive a structural screw without a pilot hole, the engineering specs are likely better documented and the manufacturing tolerances are probably tighter as well. </span></div>
<div><span style="font-size: 13px; font-family: Cambria;"><br></span></div>
<div><span style="font-size: 13px; font-family: Cambria;">FWIW: I think that using unflashed attachments in these litigious times is unwise. It's not consistent with best practices in the construction industry. It does not meet building codes. It violates the roof warranty. It makes your competition look good. </span></div>
<div><span style="font-size: 13px; font-family: Cambria;"><br></span></div>
<div>
<div><span style="font-size: 13px; font-family: Cambria;">We ran our first article on this topic 4 years ago, in our inaugural issue of SolarPro magazine:</span></div>
</div>
<div><span style="font-size: 13px; font-family: Cambria;"><br></span></div>
<div><a href="http://solarprofessional.com/article/?file=SP1_1_pg72_Fain"><span style="font-size: 13px; font-family: Cambria;">http://solarprofessional.com/article/?file=SP1_1_pg72_Fain</span></a></div>
<div><span style="font-size: 13px; font-family: Cambria;"><br></span></div>
<div>
<div><span style="font-size: 13px; font-family: Cambria;">The industry has come a long way since then, both in terms of awareness and in terms of off-the-shelf flashed attachment options. There are so many quality flashed attachment solutions to chose from now that I'm not sure why anyone would knowingly expose themselves to a possible construction negligence claim.</span></div>

If you do need to trim the flashings installed around the skylight, then I would recommend adding sealant to these penetrations. We ditch the included lag and use a 5/16” GRK RSS (self tapping structural screw). The combination works great and does not require a pilot hole.</span></span></div>
