A metal roof could be the perfect choice for your home if you want a white roof that keeps your home cooler in the summer and you want a roof that will last for many years. It's easy to switch to a metal roof, and since metal is so light, you don't have to worry about it being too heavy for your home. Here's an overview of metal roofing installation.
Tear Off The Old Roofing
Your roofer will talk to you about tearing off the old asphalt shingles or leaving them and applying the metal roofing on top. If the deck of the roof is in good shape and you only have one layer of shingles, it may be possible to put a metal roof on top of asphalt shingles. If not, then the old roofing materials are torn off all the way to the deck, and that entails having a dumpster parked in your yard or driveway to collect the debris.
Prepare The Deck
Your old deck can be used as long as it's solid and in good shape. If it has any rotted areas, these need to be cut out and replaced. When the deck is ready, your roofer may add insulation and underlayment. Rigid board insulation is a good choice for the roof since it is smooth and flat.
Your roofer will choose the best way to insulate the roof and will also choose the right underlayment. They might choose felt or plastic to add rain protection and to cover the entire surface of the roof. Once the insulation and underlayment are in place, the roofer adds wood slats across the roof. These slats allow air to circulate under the metal roofing once it's installed.
Attach The Panels
Standing seam metal panels are applied by nailing them down and overlapping them. Then the seams are sealed so no water can leak between the panels. Since the panels come in stock sizes, the roofer has to cut them to size to fit the shape of your roof.
The panels are attached in a way that allows ventilation to flow through the flashing at the edge of the roof and out through the ridge cap on top. This eliminates problems with dampness that could potentially cause roof damage or mold.
While the top of the roof is insulated well with rigid board insulation, the roofer might suggest additional attic insulation too. The insulation combined with the white color of a metal roof could make the roof more energy-efficient and help with your energy bills. Of course, you don't have to choose a white roof if you prefer a different color since metal roofing comes in several colors.
