How To Install A Metal Roof

Posted on: 5 February 2015

If you are looking for a new roofing option for your commercial building, why not consider a metal roof with corrugated slats? This type of roof has a variety of benefits, from the longevity, to the ability to withstand cold, heat, and other elements. If you intend to do some of the work yourself, the following tips can help you get the roof installed.

Gather Your Supplies

You will need a variety of tools and supplies to install a metal roof, so it helps to first gather the supplies you need. If you regularly do DIY jobs, then you might have some of these on hand. Others can be picked up at your local home improvement store. For installing a metal roof, you will need:

  • Eye protection
  • Safety harness
  • Gloves
  • Roofing nails
  • Vapour barrier
  • Broom
  • Roofing spade
  • Hammer
  • Metal roofing panels
  • Metal roofing screws
  • Closure strips
  • Screwdriver
  • Ridge panel
  • Roof caulking and gun

Get Prepared

Before you start walking up the ladder and working on the roof, get yourself ready. You need to be safe during any roofing DIY project, which includes wearing sturdy boots, gloves and eye protection. You should also have a safety harness on when you are working on a roof, just in case. Grab your ladder and put it against the building, making sure it is in a location where you can get onto the roof easily, but is also sturdy.

Remove the Old Roofing Materials

You will also need to get rid of the current roofing materials before installing your metal slats. This is if you are not planning on covering the current shingles, which you might be able to do in some cases. However, many people find it easier to simply remove the current shingles, and start fresh. You can use your roofing spade to remove the shingles one-by-one. Make sure you know your local regulations for disposing of them properly. Once the shingles are all off the roof, take your broom and sweep the entire roof surface. You should also remove any nails or screws that are sticking up.

Add the Vapor Barrier

It is important that you first add a vapor barrier for insulation, as metal roofs can sometimes cause it to get too warm inside your business. Unroll the vapor barrier across your roof, going one section at a time. The vapor side must be laying against the roof. Use galvanized nails to nail down the vapor barrier. The vapor barrier can be attached to the trusses or the roofing deck. Next, get your closure strips and attach them on the eaves, using galvanized nails to fasten them securely. They might have adhesive instead, depending on the type you purchased. Use roof caulking to seal the edges of the strips.

Install the Panels

Finally, you are ready to add the metal corrugated panels. Lay them down on the roof, one-by-one. They should fit securely over the closure strips. To secure the panels, use your metal screws with the attached washers. It helps to start at the lowest part of the roof, then going up to the next row to install the next panel. The sides of the panels should overlap with caulking in between them. You want caulking between rows to avoid getting water in the panels. Add the ridge panel at the edge of the roof when all other panels have been placed. Talk to local experts, such as Danny Odom & Son Roofing, for more information.
