Which Measurements Do I Need?
Use the reference table below to prepare your site survey before using the calculator. Accurate measurements ensure your parts list reflects real project requirements and reduces the risk of under-ordering.
| System | Measurements Needed | What Else to Count on Site |
|---|---|---|
| Aluminium Gutters | Total eaves length (m) | Count the number of 90° and 135° angles (external and internal), gutter outlets (note the required diameter), and stop ends (left and right hand where applicable). Select your bracket type — rafter, rise and fall, or fascia bracket. |
| Aluminium Downpipes | Total drop height per stack (m) | Count the number of offset swannecks per stack and note the projection distance (80–250mm, 80–500mm, or 80–1000mm). Also count any bends (92.5° or 112.5°), branches, and shoes at the base of each stack. |
| Aluminium Fascia & Soffits | Roofline perimeter (m), fascia depth (mm), soffit overhang width (mm) | Count the number of external and internal corner covers (90° and 135°) and gable box end sections. Note whether soffit requires ventilation — select Vented or Unvented accordingly. Made to order, non-returnable. |
| Aluminium Wall Copings | Finished parapet wall width (mm), total run length (m) | Count the number of 90° angles, stop ends, and stop end upstands. Note any T-junctions where coping runs intersect. The secret fix mechanism and bracket spacing are calculated automatically. Made to order, non-returnable. |
