Metal roofing is not only visually attractive but also more durable than shingles. If you are considering a metal roof, you may be wondering if you can install it on shingles. We will answer this question in this blog, please keep reading.
Generally speaking, you can install a metal roof over shingles. However, you need to consult the local construction department first. In some areas, the government only allows one layer of the roof to be placed over the shingles, while officials in other places may allow you to place two-layer roofs over the shingles.
Longer service life. The service life of different metal roofs is different, but generally between 40-70 years.
Stronger applicability. Whether it is a hot summer or a cold winter, whether it is strong wind or heavy rain, metal roofs can protect our houses from damage.
Low maintenance costs. Metal roofs generally have better strength than wooden roofs and are not easily deformed or damaged. Therefore, the frequency of maintenance is extremely low, and the overall maintenance cost is lower.
Better decoration. They can come in a variety of colors and finishes, including natural cedar shakes or a stone look.
Higher cost. Metal roofs are much more expensive than shingles. Even if it can be used for decades and can spread the average annual cost over time, many homeowners simply cannot afford the upfront cost of installing a metal roof.
Louder noise. Metal roofs can well protect our houses from being damaged by bad weather, but metal roofs may produce loud noises when there are heavy rain and hail. We can increase the sound insulation layer to reduce noise, but at the same time, it will increase the cost.
Firstly, use measuring tools to measure the length, width, and slope of the roof, calculate the required metal roof area, and purchase more metal roof panels and roof screws.
Remove the old shingles, check whether the roof sheath underneath is damaged, perform necessary repairs, and install a layer of roof insulation according to the roof manufacturer’s recommendations.
Next, install the metal roof. Overlap the first metal roof slab 1/2 to 3/4 inch to the edge of the roof and at right angles to the roofline. Place the next metal roof to overlap it and install roof screws vertically along each rib in the roof. Continue to place the metal roof panels until the roof is completely covered.
Tin roof: Tin is the most commonly used type of metal roof, but the used material is actually galvanized steel roof or aluminum roof. Although the tin roof is strong and durable, it will make a little noise if it is windy or rainy.
Copper roof: Copper roof is popular among consumers because of its beauty and anti-rust properties. Its economic cost and installation cost are high, but the copper roof panel can resist bad weather and play a good role in protecting the structure of the house.
Aluminum roof: Aluminum metal roof is lightweight and anti-rust. Because of its resistance to saltwater corrosion, it is an ideal choice for coastal cities. But it generally requires an additional layer of protective paint and is easily deformed.
Steel roof: Steel roof may cost more. If you install the steel roof on asphalt, galvanized steel is the most common steel roof. It is made by using a soft zinc layer to protect the inner layer.
Zinc roof: Zinc metal is corrosion-resistant and recyclable. It is a relatively flexible metal, so the zinc metal roof may be damaged by hail or extreme weather.
Corrugated metal roof panels: Corrugated metal panels are increasingly popular among home DIY enthusiasts due to their strength and corrosion resistance.
