Roofing for the Here and Now The roofing industry has changed quite a lot over the years. These days, homeowners are rarely opting for the standard, 3-tab shingles that were so popular a few decades ago. Instead, they are going with architectural shingles, and in some cases, with even more eco-friendly options like green roofing or slate. Whether you're shopping around for a new roof or are thinking of having repairs made to your current roof, it pays to be educated. Learn the basics on this blog, where we discuss roofing in the modern world. We explore various roofing materials, roofing techniques, and how to find the right roofer.



Metal roofs are becoming more and more common. Homeowners love that they are long-lasting, impervious to rot, and great at shedding snow. More and more roofing companies are beginning to install metal roofs, so you should not have trouble finding someone to put one on your home. Once the work is scheduled, however, you may find you have one or more of the following questions about your roof and its installation.

What kind of metal is the roof made from? 

Unless your roofer specified otherwise, the metal roof is probably made from galvanized steel. This is steel that has been coated in a special, rust-proof, zinc-based layer. This layer will prevent the steel core from coming into direct contact with water, which prevents rusting. Some metal roofs are made from aluminum, but those are really only used in coastal areas where contact between steel and salty air is a concern. 

Is there anything installed under the metal?

In most cases, yes. Your roof already has what's known as a roof deck, which is a surface made from plywood. This can be left in place, or if it is rotten or damaged, the roofers will replace it. On top of the roof deck, the roofers will put a layer of insulation. Often, foam board insulation is used since it's easy to install and doesn't take up a lot of space. The metal panels will then be installed over the insulation.

How long will it take to install the roof?

Most roof installation jobs can be done in a day. If your roofer has not let you know that they'll be there multiple days, then they probably plan on doing the job in one day. Sometimes, if you have a big roof, they might strip the old roof off on the first day and put the new one on the second day.

Can the metal roof be installed over your shingles?

Occasionally, roofers do install metal roofing directly over shingles. This is an option if you need to save money. However, it can trap moisture in the shingles and lead to molding. Unless there is a specific reason to do this, it's usually best to avoid it, and your roofers probably won't do it.

With these questions answered, you should feel more comfortable and confident having a metal roof installed on your home. Don't hesitate to contact a roofing service if you have any other concerns.
