Depending on the type of gutters you want, expect to pay anywhere from $2 to $6 per linear foot for aluminum gutters. Copper gutters could run as much as $20 per linear foot. [3] X Research source Expect to pay approximately $2 per linear foot for downspouts, and $6 to $10 each for the brackets that attach the gutters to the fascia. [4] X Research source

Think about replacing the fascia with more resistant material, or just sticking with wood. [6] X Research source If you believe the rotting is caused by excessive moisture due to ineffective gutters, then wood might acceptable. (You are going to install working gutters, after all). If you believe the rot to be caused by other factors, consider choosing a material like aluminum or vinyl that withstands the elements a bit better than wood.

Longer gutters (35 feet and longer) will slope from the center to each end. They will start at the same height in the middle and tilt downward to the edges, ending at the same point. Shorter gutters should tilt from one end to the other. They should start at a high point and end at a lower point.

Mark the high point on the fascia, 1. 25 inches (3. 175 cm) below the roof flashing with a piece of chalk.

For example, if you’re working on a 25 foot (7. 6 m) fascia board, your end point will be roughly 1-1/4 inch below your high point.

Brackets will either snap onto the gutters or will be mounted into the face board first, depending on the type of gutters you purchase. Review the manufacturer’s recommendations for your particular type of gutter.

A bracket should be mounted to the face-board every 18 to 24 inches (45 to 60 cm). Use a stainless steel lag screw long enough to penetrate the face-board at least 2 inches (5 cm).

This aluminum strip can be spray-painted ahead of time to blend in seamlessly with the color of the gutter. Make the strip long enough to extend an inch or two beyond the top of the gutter. Cut a triangular shape into the top of the extending strip, and then fold each corner or the strip over onto the top of the gutter, creating a clean look.

To get the downspout to connect with the outlet tube, crimp the downspout with some pliers. Fasten the downspout to the gutters and the downspout to the outlet tube either with pop rivets or the appropriate screws.
