The most frequently asked questions that we get from our customers, about snow guards, are “How do I know which guard to buy?” and “What kind of layout should I use when installing them?” Luckily, for our customers, we have developed a free tool that is proven to take all of the guesswork out of this process. Let me walk you thru the basics of www.SpacingTool.com.
There is no such thing as a “standard” snow guard layout, every project is unique. The most effective layout method is to use multiple staggered rows to control the movement and roof loading. We use several factors to determine the right layout for your project.
Step one is Panel Profile Selection. This step is crucial in ensuring a proper layout for your roof. We will be basing our test roof on the Imperial Rib Metal Panel By American Building Components. This is a very common panel commonly referred to as a 9” r-panel because the ribs are 9” on center. We have the option of screw down or glue down attachment.
Most roofing companies will have profile diagrams on their websites that will at least show some of the dimensions associated with the particular panel. With older roof panels of unknown origin, it will be necessary to take a look at your project’s roof panel in person before making your selection. Guessing is not recommended at any point during this process.
Once we have selected the matching panel profile (“R” Panel), the SpacingTool will move us forward to step 2 “Panel Details”. For Our “R” Panel, Spacing Tool will ask for the Valley Width and the Flat Area Width. Luckily, ABC’s website shows the on-center spacing of our test panel as 9”, so we do not need to measure that. We do, however, need to measure the width of the flat area between the two minor ribs of our panel. We have determined that the width is 1.5”. Once we select our appropriate dimensions from the drop down menus, we can move on to step 3
Step 3 is selecting the “Method of Attachment”. This is the time for you to decide whether or not you will be screwing down your guards or attaching them with adhesive. Depending on the roof panel that you select in Step 1, you may not be given a choice. An example of this would be a standing seam roof. Due to the installation process of this type of panel, screw down installation of snow guards is prohibited and typically voids the roof’s warranty. Because of this, we have programmed SpacingTool to not allow this as a selection in these situations. *Always consult your roof’s warranty before installing any roof accessory.
Our test panel allows us to install our snow guards using either method of attachment. Because we will be installing in the late Spring, I will be using adhesive for this project. Please note that our SureBond SB-190 adhesive requires approximately 28 days at 50 degrees Fahrenheit to cure fully. Once I make my selection, we can move on to the next step.
