5 RIB INSTALLATION GUIDELINES Caution: 5 Rib roofing panels must be applied on a minimum roof pitch of 2½:12 or greater. Important Notice: This guide must by read in its entirety before beginning installation. This guide is supplied by FABRAL, Inc. for use by its customers, and is intended to be a guide only. This does not replace local or state building codes. FABRAL, Inc.
MINIMUM RECOMMENDED TOOLS & EQUIPMENT Caulking Gun—Used for miscellaneous caulking and sealing to inhibit water infiltration. Chalk Line—Used to assist in the alignment of panels, flashings, etc. Electric Drill—Used to drill holes such as those required for pop rivet installation. Electric Nibblers or Metal Shears—Used for general metal cutting, such as cutting the panels in hip and valley areas. Some installers prefer using a circular saw with a metal cutting abrasive blade.
SAFETY CONSIDERATIONS Never use unsecured or partially installed panels as a working platform. Do not walk on panels until they are in place on the roof and all of the fasteners have been installed. Metal roofing panels are slippery when wet, dusty, frosty, or oily. Do not attempt to walk on a metal roof under these conditions. Wearing soft-soled shoes will improve traction and minimize damage to the painted surface. Always be aware of your position on the roof relative to your surroundings.
ESTIMATING & ORDERING A ROOF Step 1 A. Sketch a birds-eye view of the roof and label each section (see example below.) H F I D E G B C A B Sketch a diagram of each roof section. Show all measurements (see example below.) It is important to measure exact center of the ridge to the eave edge. Do not allow anything for overhang.
ESTIMATING & ORDERING A ROOF (cont.) Step 2 From the diagram you completed in Step 1, you are now ready to develop your roofing panel cut list. Each panel covers 36” of area so the only measurements you need are the distance from the eave to the ridge and the ridge length. You can then determine the number of panels needed by dividing the ridge length by the panel coverage. (See example Diagram A below.
ESTIMATING & ORDERING A ROOF (cont.) Start with section A. The eave length is 40’ and the ridge length is 30’, with a difference of 10’. You will need 30 ÷ 3 = 10 pcs. X 10’ to reach the area where the valley starts. Remember that you have 10’ remaining to cover the area. Calculate the length of each panel going into the valley by first determining the roof’s pitch. Pitch is how much rise your roof has in inches for every foot of horizontal run.

If you have any questions, or need you materials list checked, please contact your local FABRAL Distributor.
NEW ROOFS 1. Make sure there are no nails or other objects protruding from the substrate that might puncture the underlayment or damage the roof panels. Clean all debris from the deck. Check for any high or low spots in the deck, which will cause waviness in the metal panels. 2. Check all details for possible roof penetrations, which must be added to the deck prior to roof panel installation (vented ridge for example). 3.
EXISTING ROOFS In many cases, FABRAL’s Steel Roofing Panels can be installed over existing roofing without tear-off of the old roofing. Check with your local codes or building department for the specific requirements in your area. If the roof is to be stripped down to the existing decking, follow the procedures for new roofs on page 12. Be sure to check the existing roof and repair any damaged areas prior to installation of the new roof system.
