With the cold snap coming and temperatures dropping rapidly, can your home's roof shingles withstand the cold? After all, in the freezing cold weather, ordinary shingles are prone to cracking, falling off and other problems, not only leakage of rain and wind, but also have to spend a lot of money on repairs.
First of all, let's be clear, what kind of tests does a roof face during the harsh winter months?
Traditional tiles, such as ceramic tiles and cement tiles, become brittle and lose their toughness at low temperatures, and once they are impacted by external forces (e.g., snow accumulation and hailstones), they are prone to cracking and even breaking.
This is the most common “natural enemy” of shingles in winter. When the temperature rises during the day, the snow melts into water and seeps into the seams of the tiles; at night, the temperature plummets, and the water in the seams freezes and expands, and the seams of the tiles are enlarged; repeated freezing and thawing for several times, and the tiles will fall off, loosen, and the roof will surely leak.
After a heavy snowfall in winter, a large amount of snow will accumulate on the roof. The high density and heavy weight of traditional shingles will add a lot of load to the roof, and with the weight of the snow, it will easily exceed the load-bearing limit of the roof, which will cause potential safety hazards.
Stone coated metal tiles are different from traditional tiles in that they are made of high-strength metal as the base material, covered with natural colored stone particles, and processed by special technology, which can be said to be “comprehensively crushing” the traditional tiles in terms of cold resistance.
The core substrate of stone-coated metal tiles is high-strength zinc-aluminum-plated steel, which has excellent low-temperature resistance, and will not become brittle or deformed even in subzero cold environments. In contrast, terra cotta tiles may become brittle at around -10°C.
The super toughness of the metal substrate, in the face of the pressure generated by the accumulation of snow and pressure, as well as the impact of hail, can be well cushioned, not prone to cracking, from the root of the avoidance of low-temperature brittle cracks caused by roof leakage problems.
The key to damage lies in “water penetrating into the gaps”, while stone-coated metal tiles adopt a lap splicing process, with a tight fit between tiles, and with special sealing adhesive strips, a seamless waterproof barrier can be formed. Even melting snow water can't penetrate into the gaps of the tiles, so naturally there will be no “icing and expansion to crack the tiles”.
Experiments show that in repeated freeze-thaw cycle tests, stone-coated metal tiles remain intact after 50 consecutive “icing-thawing” cycles, without any signs of loosening and cracking, while ordinary cement tiles will have gaps in about 10 cycles.
The weight of winter snow should not be underestimated, the weight of snow per square meter can be up to dozens of kilograms, if the weight of the roof tiles themselves, it is easy to exceed the load-bearing limit of the roof. The weight of stone-coated metal tiles is very light, less than 1/3 of the weight of traditional ceramic tiles per square meter.
The lightweight design not only reduces the load-bearing pressure on the roof and reduces the safety hazards caused by snow accumulation, but also adapts to a variety of roof structures, even if the old roof is renovated, there is no need to reinforce the roof load-bearing, which saves both time and effort.
Stone-coated metal shingles have become the first choice for more and more families because of their hardcore cold resistance, excellent waterproofing and long-lasting durability. If you are worried about the choice of roof tiles, or want to renovate the roof of your home, you may want to consider the stone coated metal tiles, let it for your home in the winter to build a strong and warm “protective wall”!
