Rain gutters can be a valuable investment to add to your mobile home. In addition to increasing your home’s value, they protect the home and property from water damage. Installing rain gutters is a project that can take an afternoon, or up to few days. It's best to allow a weekend for your project.

Tools and Materials Required

Keep in mind that the size of your mobile home will determine the amount, quantity, and size of some items, but the list of supplies is a general guide to get you started. Customize to your specific project needs.

Step 1 - Calculate Slope of Eaves

Use the line level and string to calculate the roof slope, and plan for the gutters to drop ¼ inch for every 10 feet of distance. Mark your measurements under the eaves with the pencil.

Step 2 - Measure and Cut Gutters

Measure the sides of the mobile home, and subtract ¼ inch for seams on each side. Mark the gutter pieces at the appropriate lengths, and use the combination square to expand the mark around the entire gutter. Cut them with the tin snips, carefully.

Step 3 - Attach Gutters

Attach the hanging brackets to the gutters, locating them six inches from each end, and every 18 to 24 inches along the length of the rain gutters. Use your ladder and screw the brackets with the #8, 1½ inch screws, just below the eaves.

Step 4 - Attach Downspouts

Cut a hole matching the shape of your rain gutter sleeve in the portion of the gutter where the downspout will be located. Do this by tracing the shape with a pencil, and punch the four corners of the area with your center punch. Cut the remaining area with your jigsaw and file the edges. Insert the rain gutter sleeve inside the gutter, lining the lip with your sealant. Measure and cut the downspout to the required length.

Step 5 - Connect Gutters

Before screwing your downspout into place, be sure it fits properly. Screw it together after placing the assembly over the connectors and verifying the fit. Attach an end cap to the final portion of gutter, and use your pliers to crimp the edges. Screw the aluminum bands to the walls after wrapping around the downspout. Install the end and elbow pieces of the gutter. Create a watertight seal by applying sealant to the seamer pieces, and install them over the gaps between the gutter sections.
