Installing a Ribbed Metal Roof

Cristian choose an "Ideal; Ameri-Cana" ribbed roof for his horse barn because it is made of especially strong steel 3' wide panels with reinforced, steeper ribs and anti-syphon grooves to prevent any leaking, while a great design for a low pitch. This roof is strong enough to easily install directly onto the existing purlins; although a few will need replacing first. Above you can see the first metal panels installed in the upper left corner and some of the old plywood sub-roof has been left on the very end of this roof side to prevent the entire side from racking (twisting out of square).

Here it is from the opposite direction.

The first panels are installed so the prevailing winds will sweep over the top of ridge joints without hitting the overlap seam. A nail is used to dimple the spot for each screw first, so the special self-tapping screws are easier to get started. The metal panel (a custom-cut length) above is installed two purlins down from the ridge post which will allow for a three foot piece of clear, also ribbed, polycarbonate panel above it. We ordered the polycarbonate panels in 12' lengths which can be cut to 3' lengths with good snips.

While the sun is in the horse stalls, I am cleaning them of roof nails and old rubbish. Christian plans to keep sheep here. The surrounding five acres of meadows will be divided into two pastures to rotate, and a grass running track for Christian will go around the perimeter of both.

The other side (southern exposure) is taking longer to fix because more framing and purlins need replacing. Christian will spend about $175.00 on lumber for this project. He has left two last sheets of plywood on the roof here until the barn swallow babies nesting there fly away; soon we hope!

Team work! Bill has been fine cleaning the gutters and repairing some purlins before the boys measure the roof panels for screws and install the panels together. The panels overhang the gutters 3/4". The color of the panels is a slate color which looked more gray than blue on the paper sample sheet we selected from, but we will plant a few "Nikko Blue Hydrangeas" next to it to help them blend in.

Brothers at work. It is another hope that Leif will live at the farm with Christian next year after he finishes graduate school.


  1. Before installing, you need to find out which side of the sheet provides protection. If you install the wrong side, you will not be able to reap the benefits, which will result in withering and discolouration.
