Step where the purlins are and follow the fasteners up or across. NOTE: When walking on a roof, avoid walking on the ribs. (b) Identify the proper seam lap and the proper screw placement to fasten the sheets to the building. An After applied gable flashing is used to reduce the visual impact of the trimmed sheet. For unsquared roofs, the sheet along the gable can be trimmed along its length to match. If the deviation is not too signiicant, it can be corrected a little sheet by sheet taking advantage of the tolerances in the sheet side laps. If the roof is not square there are two correction methods that can be used depending upon the severity. NOTE: The following instructions assume that the roof is square. The dormer ridge cap needs to be cut and fitted under the main roof sheets. Installation details for this can be found at the back of this Installation Guide. Care needs to be taken to close off the cladding ribs to prevent water backing up under the sheet.įlashing where the dormer meets the main roof area can be done using Westman Steel Roof Shield, which is an EPDM dormer cap designed for this application (shown as an On-Site Flashing below). A “W” valley is more effective in channeling water off the roof than a “V” type. The roofing sheets should be cut at an angle to accommodate the pitch of the valley. A low-pitch roof may require a 36″ wide valley fashing, whereas a higher-pitch roof may only require one 24″ wide. The size and shape of valley fashings differ from one roof to another. Without this support the fashing will not lie fat and it will be impossible to make a weathertight seal between the roof sheet and the fashing. It is important that the valley fashing be supported by sheathing or blocking along its entire length. Where required, install the valley fashings as shown. (c) Corner and Ridge Boxes (if required):Ĭorner and ridge boxes are optional items and are installed after the eave and gable trims are in place. Use at least three fasteners per 10’6″ length of trim.

3/4″) and fasten the top nailing fange of eave trim to allow a space for the wall panels plus a 1/8″ clearance. There the Eave trim will cover wall sheeting, determine the wall panel depth (e.g. If this type of trim is used, it is important to properly seal (sealer tape is commonly used) and fasten the cladding sheet along the gable to prevent water from migrating under the sheet and into the building.Įave trim are installed before the roof sheets. To install gable trim, fit the pieces in place, fastening through (at 36″ spacing maximum) both top and bottom nail- ing fanges. The following installation instructions refer to fashings and trims that are either, in- stalled before the cladding (Before applied), or installed after the cladding (After applied).ĭetermine which type you have purchased and follow the appropriate installation procedure. While the use of trims/fashings are needed to ensure a weathertight building, some trims are optional and can be used to enhance appearance. Please call us for advice, or direction, as needed. The examples of trims and fashings used in this guide are only representative of the products available, and may not be recommended in certain applications. STEP 2: Install Roof Trim, Flashing and Westman Steel Underlayment Please see storage recommendations attached.ĭepending on your application, some trims need to be installed before cladding, so to avoid delays please make ensure you have what you need. Make sure to use the correct length of sheet in the correct area and be careful to stage, or secure, sheets prior to installation from the elements, and wind, at all times. Please stage your material according to roofing, side walls, end walls, sliding door sheets, trims and fasteners, and put them in a convenient location nearest to their application point.
