We currently use the 2012 code)</span></p></div><div><p class="MsoNormal" style="margin-bottom:12.0pt"><span style="font-family:"Trebuchet MS","sans-serif"">The issue that we are directly addressing is mostly pigeons hanging out/nesting under rooftop arrays, for now. I haven't heard of any specific rodent issues in our region.<br><br>I have installed the SnapNRack Edge Screen. This was on a concrete tile roof so the problem i saw with that was the screen did not contour the tile, leaving a small gap where one tile overlaps the one below it, roughly 25mm (1"). This would not be an issue with keeping out pigeons, but i could imagine that a persistent rodent could squeeze its way thru the small gap. This would not be an issue on the more common asphalt shingle roofs and i would say it is a solid product. </span></p></div><div><p class="MsoNormal"><span style="font-family:"Trebuchet MS","sans-serif"">The products i'm aware of are:</span></p></div><div><p class="MsoNormal"><span style="font-family:"Trebuchet MS","sans-serif"">SnapNRack</span></p></div><div><p class="MsoNormal"><span style="font-family:"Trebuchet MS","sans-serif"">Kinetic</span></p></div><div><p class="MsoNormal"><span style="font-family:"Trebuchet MS","sans-serif"">Heyco</span></p></div><div><p class="MsoNormal" style="margin-bottom:12.0pt"><span style="font-family:"Trebuchet MS","sans-serif"">spiffysolar<br><a href="http://solatrim.com">solatrim.com</a><br><br></span></p></div><div><p class="MsoNormal" style="margin-bottom:12.0pt"><span style="font-family:"Trebuchet MS","sans-serif"">Kinetic, Heyco, and Spiffy each seem to be basically the same; wire mesh and a j-hook that attaches to the module frame.</span></p></div><div><p class="MsoNormal" style="margin-bottom:12.0pt"><span style="font-family:"Trebuchet MS","sans-serif"">SnapNRack is wire mesh but attaches with a more more robust clip that also provides more vertical support to the mesh.

It was suggested that this may be more of a deterrent to rodents that would otherwise push their way under the mesh if it only comes down to meet the roof.</span></p></div><div><p class="MsoNormal"><span style="font-family:"Trebuchet MS","sans-serif"">Comments/Suggestions?</span></p></div><div><p class="MsoNormal"><span style="font-family:"Trebuchet MS","sans-serif""> </span></p></div><div><p class="MsoNormal" style="margin-bottom:12.0pt"><span style="font-family:"Trebuchet MS","sans-serif"">The last product mentioned, solatrim, is completely different from the rest. It looks much more solid that the rest and uses a peel-and-stick approach using a 3M adhesive tape. My first and only initial apprehension with this one is the adhesive. While 3M makes darn good adhesives, it leaves to question how it will hold up against our seasonal ambient temperature swings of above +30degC to below -40degC. Their spec sheet states it is good btwn -34.4degC to 149degC. So for me to even try it would not be within the mfgr's specs :(</span></p></div><div><p class="MsoNormal" style="margin-bottom:12.0pt"><span style="font-family:"Trebuchet MS","sans-serif"">What products have you used?
