Professional Gutter Guard recommends starting the installation process by installing the guards at one end of a continuous gutter run and working towards the other end. TIP: Keep in mind the amount of length left over for the guards covering the corners. Professional Gutter Guard recommends a minimum of 2’ of guard on each side of a corner. This allows the guards covering the corner to be securely installed.
Each 48” long section of Professional Gutter Guard should be attached to the top of the gutters with (6) 1/2” x #8 stainless steel zip screws. Three screws are to be driven through the top front edge of the guard into the top front box or round edge of the gutter. The final three screws are to be driven through the guard’s back vertical flange into the fascia of the house.
45-deg. Mitered Corner: Place a section of guard on top of the right side of the gutter corner and push the guard all the way into the corner until the end touches the house’s fascia. With a straight edge, draw a line on top of the guard from the inside point of gutter to the inside corner of the house. Remove the gutter on the right side of the corner and repeat this process on the left side of the gutter corner. Cut both guards directly along the drawn lines and place the cut guards over the gutter corner and attach as recommended. TIP: 45-deg. cuts may be made without placing the guards on top of the gutters. Check the angle of the corner before cutting. Houses and gutters corners are rarely at a true 90-degrees.
Butt Joint Corner: Place a section of guard on top of the right or left side of the gutter corner and push the guard all the way into the corner until the end touches the house’s fascia. Attach the guard as recommended. From the other side, push another section of guard all the way until the end butts up against the front edge of the just installed guard. Attach the guard as recommended. TIP: Remove about 1” off the bottom front flange of the second guard to allow it to overlap the front edge of the first guard at the butt joint. Then drive a zip screw through the overlapped section into the top front edge of the gutter and at the back were the guard overlap. This process will stabilize the butt joint and ensures no debris will enter the gutter.
45-deg. Mitered Corner: Place a section of gutter guard on top of the right side of the gutter so that the side edge or end of the guard is butted against the front edge of the opposite side gutter. With a straight edge, draw a line on top of the guard from the outside point of gutter corner to the outside corner of the house. Remove the guard on the right side and repeat this process on the left side of the gutter. Cut both guards directly along the drawn line and place the cut guards over the gutter corner and attach as recommended. TIP: 45-deg. cuts may be made without placing the guards on top of the gutters. Check the angle of the corner before cutting. Houses and gutters corners are rarely at a true 90-degrees.
2: Butt Joint Corner: From the same end of the guard; remove 1” from the bottom front flange and either 5”, 6” or 7” of the back vertical flange. Place this section of guard on top of the right or left side of the gutter so that the front edge of the guard overlaps the top outside edge of the opposite side gutter. Attach the guard to the top of gutter and fascia as recommended. From the other side, push another section of guard all the way until it butts up against the back edge of the just installed guard. Attach the guard as recommended. TIP: Remove 1” off the bottom flange and cut a 1” slot at the bottom of the back vertical flange on the second guard. This will allow the second guard to overlap the first at the butt joint. Bend the 1” back vertical flange around the corner and over the first guard’s back vertical flange. Then drive a zip screw through the overlapped section on the back vertical flange and through overlapped section into the top front edge of the gutter. This process will stabilize the butt joint and ensures no debris will enter the gutter.
Moving either right to left or right to left, butt the end of the guard up against the end cap of the gutter and attach the guard as recommended. Repeat the same installation process until all the guards are installed. Several sections of guard will most likely have to be shortened to exactly fit the continuous gutter run. TIP: Professional Gutter Guard recommends all guards to be a minimum of 2’ in length. If necessary, shorten two or more guards to achieve a minimum of 2’ per guard. Having several 2’ length guards in same run is visually more appealing and allows for better attachment.
