Know the Features of Your Shingle Roofing

The kind of roofing with covering that composes of individual overlapping elements is shingle roofing. 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. There are several different materials that made up the shingles, and these are wood, slate, flagstone, metal, plastic, and composite materials like fiber cement and asphalt shingles. The common roof material in Europe and some parts in Asia are the ceramic roof tiles called simply tiles.

Because roof shingles are the most visible aspect of a building, its patterns, textures and colors are very important features that contribute to the aesthetics of the building. Generally, the materials of roof shingles, just like the other materials on vernacular buildings, are available locally. Before construction commences, the kind of shingle is taken into consideration especially because its material would affect the roof pitch and the method of construction. The installation of some shingles are on lath while others would need solid sheathing on the deck of the roof. 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. Note that one feature that would influence the use of roof shingles are its fire rating, where some are rated non-combustible over the others, thus building codes do not allow the use of less class-A fire rating of shingles on some kinds of buildings. Compared to the fiberglass-based asphalt shingles, wood shingles and organic-based asphalt shingles are less commonly used due to its fire hazard possibility. 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. Much less common in use are the bitumen roof shingles or tile strips as called in Europe, and these shingles are less expensive, easy to install and can last 20 to 50 years.

The protection of paper and fiberglass asphalt shingles comes from the long-chain petroleum carbons, while it is the natural oils in the cellulose structure that protects the wood shingles, and the are important characteristics to take note when choosing your roof shingles.

Shingles are further made of other materials such as stone, fiber cement, metal, plastic and cedar shingles.
