The answer is yes in almost every situation. You can lay down a new metal roof over an existing shingle roof. It is one of the main reasons why most homeowners are turning to metal roofing. Of course, their installation doesn’t need complete replacement of the existing roof; otherwise it will be a time- consuming and expensive process.
Metal is considered as strong, very light material as it weighs less than a pond per square feet as compared to the four pounds per square foot for asphalt shingles. Hence, adding a metal roof over the existing shingles doesn’t increase the entire load for the home structure to bear.
Apart from saving the cost of completely removing the existing roof, installing a new metal roof over shingles allows you take advantage of extra insulation above your home to prevent heating and cooling from escaping. When talking about insulation, metal roofs helps in blocking heat as they reflect heat away from their surfaces rather than absorbing. That means, the addition insulation from shingles won’t trap heat emanating through your metal roof.
What Do You Consider for Installing a Metal Roof over Shingles?
• As discussed above, installing metal roofing over shingles works in majority circumstances. But it’s always wise to check with your local zoning and building departments to ensure that you receive approval for metal over shingle roof installation.
• If you notice any leaks on shingles, you need to check for rotting rafters or sheeting. You should fix these issues before new roof installation.
• If the weight of existing roof causes structural issues like buckled trusses or sagging decking, you need to address these issues prior to the installation.
• You can add some type of underlayment on the top of the shingle roofing to keep their granules away from the metal to prevent corrosion. You should get in touch a professional metal roofing contractor and discuss about the options available.
Why Do You Switch to Metal Roofing?
If you install a metal roof properly, it will last for around 40 or 50 year or more before it requires replacement.
Virtually Damage Resistant
Metal roofs stand intact in the most intense weather – that ranges from pounding hail and ice storms to winds and intense summer heat.
The metal roof is considered to be sturdy; so it won’t require costly repair regularly. They maintain their soundness year after year and decade after decade.
Less Cooling Cost
If metal roofs have special coatings, then they reflect and block heat effortlessly rather than absorbing. As a result, you will enjoy cooler temperature inside during summer; so you won’t need to switch on your AC.
