Some Information about Shingle Roofing
A shingle roofing is described as a kind of roof covering that consists of individual overlapping elements. The elements of shingle roofing are described as flat, rectangular in shape, and are laid in courses from the bottom edge of the roof up, with every successive course overlaps the joints before it. You will find shingles in different materials, from wood, slate, flagstone, metal, plastic, and composite materials like fibre cement and asphalt shingles. Ceramic roof tiles, or simply called tiles, are the dominant materials that are used in Europe and other parts in Asia.
Almost always, roof shingles are very visible, thus this aspect of a building is very important especially where aesthetics is concern with reference to patterns, textures and colors. The materials of roof shingles are usually available in your locality, just like other building materials on vernacular buildings. The type of shingle is given into account because its material would affect the pitch of the roof and the method of construction, and this is considered before the start of construction. While other shingles can be installed on lath, some would need sheathing that is solid on the roof deck. To avoid leaks, all shingle roofs are installed from the bottom going up, and it begins with a starter course with the edge seams offset. It is beneficial for many shingle installations to place them on top of an underlayment material like asphalt felt paper, and this method would further prevent leakages due to wind, rain, snow and ice dams. 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. Wood shingles and organic based asphalt shingles have become less common in use compared to fiberglass-based asphalt shingles because of the increased fire hazard. It is not a characteristic of shingles to be water-tight, thus it has a recommended roof pitch of a minimum 4:12 without additional material for underlayment.
Fiberglass-based asphalt shingles are by far the most common roofing used for the applications in residential roofing like in the country of the United States. The much less common are the bitumen roof shingles or tile strips, which are used in Europe, are easy to install, relatively affordable, and could last 20 to 50 years.
As you choose your roof shingles, be aware of its protective nature, such as the long-chain petroleum carbons that protect the nature of paper and fiberglass asphalt shingles, and the natural oils in the cellulose structure of the wood shingles.
You will find other types of shingles made of different materials, and so you have stone shingles, fiber cement shingles, metal shingles, plastic shingles and cedar shingles.
