To install gutters you will need the following tools: a ladder, tape measure, chalk line levels (string and carpenter's), power drill and screwdriver bits, fine tooth hacksaw, rust resistant (galvanized) screws, vinyl gutters, hangers, connectors, elbows, downspouts, drop outlets and corners. The most important thing is to get the correct pitch so that water will flow correctly. You need to measure the pitch so that the gutter is sloped ever so slightly towards the downspout.. After you measure this it's best to use a chalk line to mark the slope. After that it's best to use a nailgun or a Driver, which are both easier to use on a ladder. Tin snips might be needed for some jobs.
