Know Your Roof It is a good idea to do a thorough roof evaluation prior to your project installation. At this time you should do a layout on the roof confirming eve,ything on the drawingwill fit as it is intended. Any irregularities should be noted now, so that you can deal with them simply on install day. The quality of the roofing should be determined. so that any repairs or replacement can happen before or in conjunction with the installation. On a composilion roof it is Important to know as much as possible aboul the manufacturer, the age of roof, the type of substrate (plywood or oriented strand board [OSBD, the rafter size, the spacing and span, the age of roof structure, who roofed it, who built it, etc. Photos should be taken of all of the roof variables and associated with the job file for any future reference either short term or' long. Typically the building owner can look in a file and find the composition manufacturer. If not, lake a piece to the roofing yard, they can usually recognize the maker and tile rough vintage. It is then easyto obtain the written manufacturer's installation instructions for the roofing materials you are dealing with. The manufacturer's instructions will spell out exactly whatdoes and does not void the warranty of their roofing product. Most have a clause about roof temperature. This is commonly missed, but can easily be noted if you read the instructions. Officially. the roofing manufacturer's instructions supersede our instructions, as our product is weaving into theirs. 11 is also important to have their instructions in the job file, for any future reference. If the manufacturer cannot be found, there is obviously no warranty in place. On a roof that has a material and labor warranty in place (new roof), it is recommended to at least consult Ihe roo fer of record. Often the roofing contractor will void the labor portion of their warranty if another trade modifies their work. Give the roofing contractor the oplion of handling the roofing modifications, or alleast give them the opportunity to inspect and approve the modifications you make. There will be fees to this roofer, but if it maintains the labor warranty it should be good rnoney spent. Product Selection The Composition Mount is intended to fit within most composition and wood shingle roof systems, but not all. Specifically it is sized to fit within a standard 5' to 5 1/2- row or course. To confirm that the Comp Mount will match your roof, measure the course exposure of your roof. The 'exposed' surface course height should measure no more than 5 3/4". If it turns out the roof tiles are a non-standard size greater than 5 3/4-, the alternative method is to use a Quick Mount Shake Mount instead. In this case, follow the directions for the Quick Mount Shake Mount. (See Compostion Mount Instructional Video at quickmountpv.com/tech.php, then Shake Composition Video: High Definition Comp - Presidential Irregular surface - If the penetration lands in a low between two highs, it is best to shim the low under the flashing with extra asphalt to level out the surface. Irregular tooth pattern - If the shingles have a tooth pattern wherein the bottom edge jogs up and down to give it a higher profile look, it is important to understand that the excess shingle that hangs lower than the rest of the shingle is for looks only. The 5' rule starts at the top of the tooth. If a tooth interferes with the mount block, cut the tooth off.

There are two questions that must be asked when adding anything to a roof. 1. Can the roof / building / foundation handle the additional load? 2. What is to keep the new load from blowing away? It is assumed that a licensed solar installer can answer these questions. If he / she can't, he / she will need to find somebody that can. A licensed engineer is the easiest solution. Some of the racking manufacturers have guides to calculaUng a code compli- ant install as well. Many variables must be considered and determined to complete the calculation. The spacing between mounts has the variables of: strength of rail, distance between parallel rails, cantilever of modules over rails, pull out strength of mount, slope of roof, height of roof, wind zone, roof type, structural integrety of roof framing, etc. The only values in the variables above that we can provide is pull out strength and shear 6f mount. Wh provide structural test reports on all of our mounts as needed. You will need to gather the rest of the applicable information and do the calculations for your specific project. Further Resources In the process of all the research we have done, we came up with what we call the 'Wheel of Accountability'. It is a graphical look at the many official enUties that govern how waterproofing should be done. At our web site you can click on any wedge of the wheel and get the code snippets that pertain to that entity's focus on roof penetrations. Please don't hesitate to use it to your advantage. And of course if you have any feed back pro or con, let us have it. Take photos of your jobs using Quick Mount Products and submit them to us at info@quickmountpv.corn, we'll put them up in our web gallery. Put Photo Gallery in the Subject line. Product Includes The units are sold in 12 packs. Each 12 pack includes the mounting hard- ware and the mount with flashing to install 12 mounts, with written instruc- tions. Alternative Attachment Methods The Composition Mount is intended to be attached into a lumber after. Mounts are usually laid out based on the locaUon of the rafters. In some cases it is desired to place a mount where there is no rafter. In this case it is Possible to place a block between rafters, then lag into the block. In the case of metal rafters, lumber blocking the rafters is a solution, but should be done per the building's engineer of record. Shared Rail & 5" Rule On a shared rail system, where the mounts must be in an exact spol, it is important to make sure the unit is flashed property. Normally the vertical placement is guided by the exposed front edge of the shingle. If (on a 5' exposure comp) the flashing is flush with this, then you have 5' of flashing over course 1, 5- of flashing under course 2, and 2- offlashing under cours- es 2 and 3. This is important because if there is a vertical joint in course 2 the water cannot find its way under the flashing because it extends under course 3. When the flashing must be shifted to catch a shared rail, it is ad- vised to shift the mount up the roof only, leaving less Mashing over course 1, and more flashing under course 3. If it is necesary to shift downward, it is advised to move down a whole course and then shift up accordingly. Sealants It is important to put a compatible seatant into any and all holes drilied into a roof. Most roofing manufactures list a suggested, approved sealant in their specifications. In the freeze-thaw zones, it is important to follow the manufacturers' rules for freeze-thaw conditions. Use Ihe properly rated sealant for each specific application and condition. Some that may be more appropriate for asphall/composition roofs inctude Geocell 2300 and Chemlink Ml but be sure to do your own research to confirm a compat- ible and appropriate sealant with the materials you are working with.
