Can a Stone Coated Metal Roof be Installed on a Shingle Roof

Can a Stone Coated Metal Roof be Installed on a Shingle Roof? This is a very common question homeowners have when wanting to swap from a shingle roof to a stone coated metal roof tiles. Stone coated metal roof is one of the most efficient and long-lasting roofing options out there. While traditional options like asphalt shingles are still used in the majority of the properties, SANGOBUILD roofing, with its unrivaled durability and energy efficiency, is growing at an exponential pace especially in the residential space.

However, homeowners with an existed shingle roof may be confused about switching to a stone coated roof. Is it possible to install a new roof over your existed asphalt shingle roof? Or do you need to undertake a complete roof replacement project?

Technically, it is possible to install a metal roof over your shingles provided your existing roofing system doesn’t have more than four asphalt shingle layers. 

Why Stone Coated Metal Roofing Should Not Be Installed Over Shingles?

Although installing a new roof on an existing roof seems to be a very simple process, it can lead to a series of problems in a few years. Let's take a look at some of the reasons why it is best to remove existing shingle roofs before installing metal roofs.

Replacing existing roofs with energy-saving roofs is a huge investment. In this case, cutting corners only reduces the performance and value of the new roof system, undermining the overall purpose of investing in new metal roofs.

On the other hand, if properly installed by experienced professionals, the stone coated metal roof can prove to be one of the best investments you can make in any home improvement project. Let's take a look at the reasons:

l Energy-Efficient: Compared with traditional roofing materials such as asphalt shingles, metal roofs have much higher energy efficiency. Their stones can absorb heat, coupled with highly reflective coatings and ventilation grilles on the roof, which can well maintain a cool and comfortable temperature in the home, especially during summer peak periods. Having a metal roof can help you save nearly 20% on cooling costs.

l Fire and Wind Resistant: Compared with traditional materials, metal roofs have high wind and fire resistance performance. In addition, because most metal roofs are installed through interlocking or overlapping sheets, they remain intact in strong winds and storms, making them one of the most wind resistant roof systems on the market.

l Exceptionally long Lifespan: While traditional materials can deteriorate with age, metal roofs keep looking and performing like brand new for many years and years. Most metal roofs have a life expectancy of over 50 years.

l Unmatched versatility: Metal roofs have a variety of designs and styles to choose from. They have a strong adaptability and can easily adapt to any architectural style. Some products can mimic the appearance of any roof material, including slate, wood, ceramic tiles, and shingles.

l The Most Lightweight Roofing Option: Metal is a lightweight but strong roofing material that can help avoid the structural problems typically caused by heavy roofs. This is particularly common in places prone to earthquakes.
