 \nA takeoff uses project drawings and specifications to determine the quantities, dimensions and types of materials required for a construction project.  \nFor a metal roof, for example, drawings and specifications may identify the required roof cladding profile, thickness, fixing pattern, batten supports and their spacing. Software can also assist with calculating material requirements.  \nIn many cases, customers complete their own takeoff and provide Stramit with a list of materials for quotation. Where quantities have not been determined, our takeoff team can use suitable drawings or dimensioned sketches to estimate the required materials.  \nThe accuracy of a takeoff depends on the quality and completeness of the information provided. Clear drawings, dimensions and specifications help our team prepare a more accurate estimate. For example, a hand-drawn sketch with limited dimensions may not provide enough information for an accurate takeoff.  \nWHAT SHOULD BE CONSIDERED IN A TAKEOFF?  \nFor Stramit products, a takeoff may include roof cladding, wall cladding, structural, insulation, fasteners, flashingsand rainwater products, depending on the project.  \nROOF CLADDING  \nThe roof shape, dimensions and pitch all affect the quantity and length of roof cladding required.  \nThe roof pitch is particularly important when determining sheet lengths, as a plan view alone does not show the actual length along the roof slope. For example, at a 15° roof pitch, the sheet length increases by a factor of 1.035 and the hip length increases by a factor of 1.439. Allow an additional 50 mm of sheet length for overhang into the gutter.  \nThe roof width and selected cladding profile are also required to determine the number of sheets. Minimum roof pitch requirements should be checked for the selected profile. For example, Stramit® Corrugated is not suitable for roof pitches below 5° .  \nFor some roof configurations, including hipped roofs, sheet offcuts may be reused in another section of the roof to help reduce material waste. This process is commonly referred to as blocking.  \nSheets should be laid against the direction of prevailing weather where possible.  \nFigure 1. Example of blocking sheet offcuts on a hipped roof  \nINSIDER  \nTECHNICAL  \nTAKEOFFS IN CONSTRUCTION  \nSTRUCTURAL  \nFor an accurate estimate, the roof cladding spans and corresponding batten spacing are required.  \nFor an approximate estimate, total batten length may be calculated by multiplying the roof area by 1.5. The batten length for a triangular section of roof will generally be around half that of a rectangular section of the same width and length.  \nRaked sheets require support at their ends and this should be included in the takeoff. Allowance should also be made for overlapping battens where required, with an additional 15% suggested in the original technical guidance.  \nWhere practical, offcuts from one area may also be used elsewhere on the roof, as shown in Figure 2.  \nFigure 2. Example of batten layout and use of offcuts  \nFLASHINGS  \nA roof can require a range of flashing types, including ridge flashing or roll top ridge, hip capping, valley gutters, barge capping, soaker flashings and apron flashings.  \nSufficient project detail is required to accurately determine the size and quantity of each flashing.  \nRefer to Stramit’s Roof and Wall Flashing Detail Guide for further information.  \nRAINWATER PRODUCTS  \nRainwater products can include fascia, gutters, downpipes and associated accessories.  \nThe gutter type and number of downpipes required depend on factors including the roof catchment area and rainfall intensity at the building location.  \nOther items to consider may include:  \n• fascia brackets  \n• gutter brackets and snap clips  \n• corner brackets  \n• stop ends  \n• downpipe nozzles  \n• downpipes  \n• offsets  \n• astragals  \n•","cbCaic6RI5zDsUZR","https://ap.wps.com/l/cbCaic6RI5zDsUZR","pdf",376324,"English","# What is a Takeoff?\n## What should be considered in a takeoff?\n## Roof cladding\n## Structural\n## Flashings\n## Rainwater products\n## Fasteners\n## Wall cladding\n# What to look out for","[{\"question\":\"What information does a takeoff use to determine material quantities?\",\"answer\":\"A takeoff uses project drawings and specifications to determine quantities, dimensions, and the types of materials required for the construction project.\"},{\"question\":\"Why does roof pitch matter for roof cladding takeoffs?\",\"answer\":\"Roof pitch affects sheet length because the slope length increases relative to plan view; it also changes hip lengths and requires practical allowances for overhang into gutters.\"},{\"question\":\"What should be checked before requesting or completing a takeoff?\",\"answer\":\"Ensure drawings are clear and contain enough detail, verify relevant site dimensions, consider roof penetrations carefully, and avoid automatically deducting small penetrations from the cladding area.\"}]","Technical Insider - Issue 4 - October 2026 - Takeoffs in Construction | PDF"]
