Types of Roofing

Whether you’re building a new home or remodeling an existing one, the roof is an essential part of any structure. There are a variety of roofing options to choose from, including shingles and metal.

All metal roofing starts out as coil and is then rolled into panels for installation. The panels are then seamed together and sealed at different junctures, such as chimneys and valleys. Contact Kent Roofing now!

A roof is the outer covering of a building that protects the inside from precipitation and wind. Its internal structure, sometimes called a truss, is an assembly of beams and other elements that form a rigid frame to hold the roof and its external materials. A roof can be flat or sloped. Flat roofs are common on sheds, garages and other outbuildings, but they don’t offer the structural support that a house needs. Sloped roofs are more common and include a range of designs.

Typically, the internal and external parts of a roof are made from wood framing lumber such as 2x10s. Some roofs are framed on site, while others are pre-fabricated trusses that are delivered to the jobsite and craned into place. Plywood or OSB is nailed to the joists or trusses and serves as sheathing, a surface onto which roofing materials are attached. A waterproof membrane and vapor barrier, or underlayment, is then applied over the sheathing to keep rain and air out.

The edges of a roof are protected with gutters and metal flashing to prevent water damage. A downspout, located at the corner of a roof, directs water from the gutters to a drain at ground level. A piece of metal flashing placed at the edge of a roof to control the direction of dripping water is called drip edge.

Depending on the design of the roof, there are various types of vents that project through the roof. These vents are important for a home, as they allow for attic space to be properly ventilated. The vents also help to remove condensation that can build up in a home’s attic.

Sheet metal

Sheet metal is a material that comes in a flat piece and can be bent into different shapes. It is one of the most versatile materials in manufacturing and can be used to make a wide range of products. You can find it in cars, airplane wings, medical tables and even in your home. There are many types of metal that can be used to make sheet metal, including aluminum, stainless steel and copper.

There are a number of different processes that can be used to form sheet metal, including expansion, cutting and hemming. Expanding is a process that involves cutting alternating slits into a sheet of metal and then stretching it open. It is used when air and water flow are important, as well as when lightweight is more important than strength. Cutting is a common forming technique that involves removing part of the metal with a saw or cutter. Hemming is a method of joining two pieces of sheet metal together. Round rolling is another forming technique that uses a series of pairs of rolls to bend the metal into a circular shape.

Skilled sheet metal fabricators can produce custom parts for a variety of projects. This allows them to meet tight specifications and quality standards while saving time and money. In addition, they can create complex and unique parts that would be difficult or impossible to make using traditional methods.


There are few roofing materials more popular than shingles, which are individual overlapping tiles that can be used on virtually any style of roof. They are available in both regular and abstract patterns, as well as in various colors, shapes, and sizes. They can be made from a wide variety of materials, including wood, slate, clay, asphalt, and composites. They can also be applied to a variety of buildings, from residential homes and garages to commercial or agricultural structures.

One of the most common types of shingle is the three-tab asphalt shingle, which features several layers of fiberglass felt that are coated with an asphalt compound and granules. They are durable and affordable, and can withstand most weather conditions. However, extreme weather conditions such as high winds, hail, and frequent freeze/thaw cycles can shorten their life span.

Other types of shingles include architectural shingles and laminated shingles. Both have a more polished appearance than traditional three-tab shingles, and they are often designed to mimic the look of natural materials such as wood shakes or slate tiles. They can increase a home’s resale value and add a touch of elegance to any building style. They are moderately priced, and they can withstand extreme climates such as tornadoes and wildfires.

While shingles can last for many years, it is important to perform routine maintenance on your roof. Regular professional inspections can help identify damaged or curling shingles, obstructed drains and gutters, and flashing issues around vents. Catching these problems early can save you a lot of money, as repairing a minor leak can cost far less than dealing with major damage or water intrusion from an unchecked problem.

Flat roofs

Flat roofs are gaining popularity in residential houses as they can be utilised to create additional outdoor space on top of the house, or even rooftop gardens. This is particularly helpful in areas with small block sizes where a lot of outdoor space is limited, or for homeowners who want to store large household equipment like water tanks and heating systems out of sight.

While flat roofs are not completely level, they do have a slight slope to allow for proper drainage. This is crucial because without a sufficient incline, water would accumulate and potentially cause leaks inside the building. Because of this, flat roofs are usually lined with a waterproof membrane to protect the structure from rainwater damage.

Another benefit of flat roofs is that they are much easier to maintain than traditional pitched roofs. Because they don’t have a steep slope, it’s much simpler for homeowners to climb up and carry out regular inspections or perform basic maintenance tasks such as cleaning the gutters.

The only drawback to flat roofs is that they tend to absorb heat more easily than pitched roofs, which can make your home feel warmer in the summer and colder in the winter. However, this can be overcome by installing solar panels or using a well-insulated and properly maintained flat roof to reduce the energy required to heat or cool the property.

Overall, flat roofs are a great option for residential buildings that require less maintenance and provide a more contemporary aesthetic. However, it’s important to consult a professional flat roofing contractor before you decide on this type of roof for your home or business. They can help you determine if a flat roof is the best option for your needs and recommend the appropriate roofing materials to ensure long-lasting protection and minimal repair costs.

Metal roofs

Metal roofs are a durable option for commercial or residential construction. They can withstand high winds, rain and snow. They require less maintenance than traditional shingle roofs and last 50 to 100 years. They are also energy efficient and may qualify for a tax credit.

The metal roofing industry offers a wide range of styles, colors and materials to choose from. Steel (galvanized or galvalume), copper, aluminum and tin are common materials. They are available as pre-formed panels or in the form of standing seam and exposed fastener roofs. Some systems allow for the attachment of the sheathing and the structural diaphragm in one piece, eliminating the need for an extra sheathing layer. Panels can be fabricated on-site for a more customized fit and to reduce leak potential. Some roofs have a granular coating for a more natural look or can be stamped to imitate shingles, slate, tile or shakes.

Each type of metal has its strengths and weaknesses. For example, galvanized steel is inexpensive and durable. However, it rusts easily in certain climates. Steel also expands and contracts more than other materials, which can cause stress on the panels or seams if not allowed for in the design. Aluminum is a more expensive material but it is highly recyclable and does not rust as easily as steel. However, it has fewer color options than other metals. Zinc is a relatively new option that has been growing in popularity in the U.S. It is lightweight and requires less material to construct, which saves on the engineering of the framing of a building. It is also non-combustible, which means it resists fire from outside sources better than other roof materials.
