K-style gutters are L-shaped on the back, while the front has step-like increments. Half-round gutters are round on the bottom with a lip on the top of the outside edge.
Continue around the perimeter of your home until you have measured and recorded the entire length of the existing gutters. Gutters and downspouts are typically sold in 10 ft (3. 0 m) lengths.
Each downspout requires 3 elbow pieces, so add those to your notes as well.
Carefully climb back down the ladder when you’re finished.
If you have a simple gable-end roof, you only need to multiply the length of one side by the width of the same side, then multiply the sum by 2 to get the total square footage.
For instance, a 2 in (5. 1 cm) gap means the roof has a 2-in-12 pitch and a 6 in (15 cm) gap means the roof has a 6-in-12 pitch.
For instance, if the square footage is 1,000 feet (300 m), the roof-pitch factor is 1. 2, and the intensity is 5. 7, multiply 1,000 x 1. 2 x 5. 7 to equal 6,270.
If you don’t want to add downspouts and the square footage of the roof is more than 7,960 feet (2,430 m), you’ll have to order custom 7 or 8 in (18 or 20 cm) gutters.
