A shingle roofing is described as a kind of roof covering that consists of individual overlapping elements. The elements in roof shingle are laid in courses from the edge of the roof going up, with every successive course overlapping the joints beneath it, and these elements are usually flat and rectangular in shapes. Wood, slate, flagstone, metal, plastic, and composite materials like fibre cement and asphalt shingles, are the various materials that shingles are made of. In Europe and some parts in Asia, the ceramic roof tiles, usually just called tiles, are in dominance in use.
A building’s aesthetics is very important where patterns, textures and colors are concern, and since roof shingles are highly visible, they contribute greatly to this aspect of a building. Just like the other building materials of vernacular buildings, roof shingles are usually made of materials that are locally available. Since the material affects the pitch of the roof and its construction method, the type of shingle is being considered before construction begins. The installation of some shingles are on lath while others would need solid sheathing on the deck of the roof. Beginning with a starter course and edge seams offset to avoid leakings, note that all shingle roofs are to be installed from the bottom upward. To further prevent leaks from wind, rain, snow and ice, there is an underlayment material like asphalt felt paper where many shingle are placed on top as these shingles are installed. Consider though that some roof shingles are non-combustible and have better fire rating than the other kinds that would affect the use, especially some building codes do not allow less than class-A fire rating to be used on some types of buildingins. Compared to the fiberglass-based asphalt shingles, wood shingles and organic-based asphalt shingles are less commonly used due to its fire hazard possibility. Since no shingles are water-tight, their recommended roof pitch is 4:12 devoid of underlayment material.
In a country like the United States, the most common roofing by far is fiberglass-based asphalt shingles as being used for residential roofing applications. There are the tile strips or bitumen roof shingles, which are less commonly used in Europe, and these are relatively affordable, can be installed easily, and can last 20 to 50 years.
When choosing your roof shingles, be aware of the source of their protection, like the protection of paper and fiberglass asphalt shingles comes from the long-chain petroleum carbons, while the wood shingles are protected from the natural oils in the cellulose structure of the wood.
Other kinds of roof shingles are stone shingles, fiber cement shingles, metal shingles, plastic shingles, and cedar shingles.
