Hang Your Own Gutters On Your Metal Building

Installing gutters on metal buildings is a little different than installing them on wood-framed structures. Below, you will find a guide to assist you with the installation of your gutter system on your metal building.

To complete this project you will need:

  • Gutters
  • Steel gutter straps
  • Ladder
  • Aviation snips
  • 3 sets of self-locking pliers
  • Measuring tape or measuring laser
  • String line
  • Drill and 1/8" drill bit
  • Rivet gun and 1/8" blind rivets
  • Thick work gloves

Think Safety

Before getting started take a minute to freshen up your ladder safety knowledge. OSHA has provided some useful information to help you choose the right ladder for the job and use it properly.

  • Inspect the ladder for defects.
  • Position the ladder on sturdy ground.
  • Use a ladder that extends beyond the highest peak that you need to access.

Get Measurements

Measure the length of the eave. This can be a nearly impossible task if you are working on your own. If this is the case, consider using a laser measuring device to expedite the measuring process. These devices can be rented from your local home improvement store. Add an inch to each end to allow for a slight gutter overhang.

Cut the Gutter

After you have your measurements, you can cut the gutters to the size that you need. Use the aviation snips to carefully cut the gutters. Wear gloves while cutting to prevent cuts to your hands because the metal will be very sharp.

Hang the Gutter

Run the string line to help hang the gutters properly. Remember that the gutters must be slightly sloped to help the water run to the downspouts more effectively. If you are installing downspouts on each end, the peak height of the gutter can be in the center with the two sides sloping slightly downward. The slope only needs to be slight – you shouldn't even really be able to tell that they are sloped when you look at them from the ground.

Now, get some help with this next step. Hold the gutter up to the eave and use the pliers to lock them into place. Drill a hole through the gutter flash and the roof. Use the rivet gun to attach it.

Once the gutter is hung, install the gutter straps about every 3 feet. These straps are hooked to the outer edge of the gutter and riveted through the gutter and then attached to the roof.

If you are unsure of your ability to complete this project on your own, talk with your local gutter contractor like one from Alaka'i Raingutters & Supplies about installing it for you.
