What is the ideal gutter size for your roof? How do you know if it will support the volume of water and the entire structure? We invited Ueslei, from the channel @uvscalhas to teach us how to calculate roof gutters! 1st tip: Amount of rain that falls on the roof 4.02 liters / min per m² 2nd tip: calculating the roof area Width x height = area in m² Multiply the area of your roof by the amount of rain. Divide by 2. The result will be the amount of water your roof receives. Remembering that the table follows the gutter with a 2% slope Rectangular galvanized steel gutter (in cm) 15 x 7 = 227 l/min flow 20x10 = 886 l/min flow 30x15 = 2612 l/min flow 40x20 = 5624 l/min flow Semi-circular PVC gutter (diameter in mm) 100 = 348 l/min 150 = 1026 l/min 200 = 2209 l/min 250 = 4005 l/min Nozzle (diameter in mm) 100 = 219 l/min 75 = 150 l/min Find the materials to make your gutter at obramax! #obramax #roofing #gutter #guttercalculation At Obramax you will find EVERYTHING you need for your project, from foundation to finishing!
