You may put off replacing your sinking or leaking rain gutter because you are concerned about the cost and labor required. However, by replacing them yourself, you can save a little money and be sure that your home is protected from water damage during heavy storms. Most hardware stores and home improvement stores sell gutter systems that are designed for easy, do-it-yourself installation.
Get the right to slope
Stagnant water in your gutters can cause corrosion and leaks so it is important to ensure that they drain properly. Installing them at the correct slope prevents water from pooling in gutters and ensures proper drainage. Each channel must be positioned so that it slopes towards a downspout. The slope should measure approximately 1/2-inch for every 10 feet of culvert. You can use eaves boards in your home as a guide for sloped gutters, but check that they are level beforehand.
Preassemble the Channels
Before installing the gutters for your home, assemble as many parts as possible on the spot. Trying to assemble them, while at the top of a ladder, can be extremely difficult and dangerous. Some channel systems come with silicone gaskets that allow the pieces to fit securely. If your channels are not equipped with gaskets, use PVC glue to seal the seams. Do not use cement on the downspouts, however, because you may have to remove them at some point to clear the clogs.
Prevent water damage with flashing light
To avoid water damage to the fascia of your home, place your gutter apron sheet metal under your roof shingles and over the gutter back edges. The flicker prevents water from seeping behind the roof guttering and damaging the fascia. The flashing must be bent for installation so if you can’t find intermittent pre-bent at your hardware or home improvement store, they will have a sheet metal fabricator or aluminum siding contractor bend it for you. Place the flashing under your roof shingles and secure it in place with 1-inch nails approximately every 2 feet. For added security, allow a couple of inches of overlap between the flashing sections.
Use a downspout crimping tool
Each channel section has one end folded over so that the pieces fit securely within each other. Downpipe lengths also feature a wavy end, but you will need to crimp the end of any cutter piece you will be using in order to fit inside the next piece. A pair of needle nose pliers can do the job if you only have a couple of crimp sections.
