About Roof Shingles
Roof shingles are a type of roof covering made up of separate, overlapping components. These components are typically flat, rectangular shapes that are arranged in upward courses, each of which overlaps the joints beneath it, starting at the bottom edge of the roof. The roof rafters support shingles, which can be made of a variety of materials including wood, slate, flagstone, metal, plastic, and composites consisting of fiber cement and asphalt. The term “tiles” is still frequently used to describe ceramic roof tiles, which are still common throughout Europe and some regions of Asia. Compared to wall shingles, roof shingles may decay more quickly and require higher water resistance. In the US, they are a widely used roofing material.
Since they are nearly always very noticeable, roof shingles play a significant role in the patterns, textures, and hues of a building’s aesthetics. Like other building components on vernacular structures, roof shingles are frequently made of a material that is readily available nearby. Prior to construction, the type of shingle is considered because the material impacts the roof pitch and construction technique: While some shingles require solid sheathing (sheeting) on the roof deck, others can be put on lath. To prevent leaks, the edge seams on all shingle roofs are offset and fitted from the starter course up.
To avoid leaks even from wind-driven rain, snow, and ice dams in cold areas, many shingle systems benefit from being laid on top of an underlayment material like asphalt felt paper. The roof’s shingles on one side may simply continue past the ridge at the ridge or there may be a ridge cap made of boards, copper, or lead sheets.
The ridge top of an asphalt shingle roof is made of flexible asphalt shingles. Some building rules forbid the use of roof shingles with fire ratings lower than class-A on certain types of structures because they are combustible or have a worse fire rating than others. Wood shingles and organic-based asphalt shingles are now less prevalent than fiberglass-based asphalt shingles because of the greater fire risk. Since no shingles are waterproof, a 4:12 roof pitch is the bare minimum that should be used without extra underlayment materials.
Types Of Roof Shingles
Asphalt shingles made of fiberglass are by far the most popular roofing material used for residential roofing in the United States. They are far less prevalent and known as tile strips or bitumen roof shingles in Europe. They are simple to install, reasonably priced, durable for 20 to 60 years, and in certain places recyclable. There are different designs and colors for asphalt shingles.
While wood shingles are shielded by natural oils in the cellulose structure of the material, paper and fiberglass asphalt shingles are largely protected by long-chain petroleum hydrocarbons. These oils soften over time in the hot heat, and when it rains, the oils are gradually wiped off the shingles. Eaves and intricate rooflines receive more water during rain, which makes them more vulnerable to erosion than other locations.
Over time, the loss of the oils leads the wood and asphalt shingles to deteriorate and shrink, exposing the nail heads underneath. Once the nail heads are exposed, water from the roof may seep into the building along the nail shank, causing the roof’s supporting elements to deteriorate and interior ceilings and paint to become damaged by damp.
Shakes and shingles are the two main classifications of wood shingles. Generally speaking, wood shakes are longer and thicker than wood shingles. The fundamental distinction is in the method of construction, with shakes typically being split, at least on one side, whereas shingles are always sawn. Due to the fact that a wood shake is split with the grain of the wood rather than being sawn against it like a shingle, it frequently has a more textured appearance. Untreated wood shakes and shingles have long been recognized as a fire risk and have been outlawed in a number of locations, especially in metropolitan areas where combustible external building materials are a major cause of destructive fires known as conflagrations. A Class B fire rating can be attained using modern pressure-impregnated fire retardant treated wood shakes and shingles.
The common name for slate shingles outside of the US is slate tiles. Depending on the quality of the slate used and how well they are maintained, slate roof shingles can survive 80 to 400 years after being installed. The material itself degrades gradually and can be reused in different buildings.
When individual slates start to slide out of place and lose their peg attachment, this is the main cause of slate roof failure. Small openings may result above each slate as a result. When the slates themselves start to crumble, that is a secondary mode of failure. A gap may appear underneath a slate if the lowest portions of the slate come free. The little, strained area above the nail hole frequently fails, allowing the slate to slide as before. In the worst scenarios, a slate can simply split in half and disappear entirely. Torching, or applying a mortar fillet beneath the slates to secure them to the battens, is a typical repair method for slate roofs. This may be used to repair something or to hold slipping slates, or pre-emptively on construction.
