What is an asphalt shingle roof? (Materials, Durability, and More) Are you ready for a new roof? Are you trying to find the right roofing material for you? If so, you may be considering asphalt shingles for your roof. But what is an asphalt shingle roof? Luckily, we're here to explain it to you. At the end of this article, with what is an asphalt roof, types of asphalt coating and 3 things that should be noted about asphalt shingle roofs, it is noteworthy that the oxidized bitumen even before installing the shingle on the roof, begins to age and lose its properties. he does From the moment it is produced in the factory, the proportion of oil in the bitumen composition decreases rapidly and the solid properties increase. And the more time passes from the moment of shingle production to the time of installation (under the influence of various natural factors on the roof shingle, such as: sunlight, snow, rain, sudden temperature changes, etc.), this process increases. Loss of oil leads to cracking and collapse. . . However, to improve the properties of the shingle, modifiers are added to bitumen (polymeric materials) that change the structure of the material and improve performance. In fact, the introduction of special components into bitumen brings it closer to the properties of polymers, slows aging and makes it very resistant to external factors. Therefore, modern flexible shingles are free from the above disadvantages.
