Contractors Keep Us Sheltered

Look up at the ceiling over your head, and also think about the roof above it. You are lucky to have that shelter. Of course, you worked hard to afford it, but that point aside — someone else worked really hard to build it. Our point here is that without construction workers and contractors, we would not have homes in which to live. We all value our homes, and of course, we value the other buildings we spend time in, too. Everyone has a different way of showing their appreciation for this work. Our way is to write about construction on this blog. Your way could be reading about construction on this same blog!

The Method For Your Metal Roofing Installation Depends On The Type Of Roofing You Choose

by Glenda Perkins

A metal roof is a good choice for a business, home, or outbuilding on your property. Metal is durable, so it lasts a long time. The panels are also installed so they resist wind lifting and leaking. In addition to being protective and durable, metal roofing is attractive so it enhances the appearance of your home or building. Here are some steps in the metal roofing installation process.

Choose The Roof Base

If you're putting a metal roof on your home, you'll also want a deck underneath the roofing. The deck might be made of oriented strand board or plywood. If your home currently has asphalt shingles and your roof is in good shape, the contractor might put the metal panels on over the asphalt shingles.

Metal roofing doesn't need roof decking to be installed since the panels are screwed to the rafters or purlins. If you're installing the metal roofing on a detached garage or outbuilding, you may prefer to leave the plywood decking off.

If the roofer will install the metal panels over plywood or oriented strand board deck, they'll probably put down underlayment first to provide additional protection from water leaks.

Apply The Metal Roofing

Metal roofing installation has to be done according to the roofing manufacturer's instructions to protect the warranty. The manufacturer may stipulate where to place the screws and how many to use. Your roofer follows the instructions for the type of metal roof you have installed since installation methods vary.

Standing seam panels lock together and have fasteners that are hidden from the elements. Other panels are screwed to the rafters and leave behind visible screws and washers. Metal panels need to be screwed to rafters or other thick supports. They can't be screwed to the plywood deck.

Metal shingles are staggered across the roof in a repeating pattern as determined by the manufacturer. The shingles lock together and fit in the drip edge and gable channel for a straight edge. The shingles are attached to the deck with nails or clips.

When nails or screws are used for a metal roof, the roofer has to ensure the right nails are used when it comes to length and material so the nails don't deteriorate due to galvanic corrosion.

The last step in the metal roofing installation is to cap the ridge with a matching metal strip. This strip can be open to allow attic ventilation or closed. The purpose of the strip is to cover the opening where the roofing materials end along the top of the roof so rain can't fall in your attic.
