Types of Roofing

Roofing is an important and complex subject that can have profound impacts on the performance of a building. It is recommended that designers consider a roof consultant or work closely with a local contractor to gain more comprehensive knowledge of the various products and systems. Roofing

Wood shingles are generally made of cypress, redwood, or western red cedar and may be plain-sawn, quarter-sawn, or hand-split. Field-applied coatings are often specified to enhance UV protection.

The shingles that cover a home’s roof are its first line of defense against the elements. Installed in an overlapping pattern, shingles shed water in the direction of the slope and prevent it from seeping into the house. But a roof’s shingles don’t just protect the structure; they also add to its aesthetic. With so many styles and colors available, it’s important to understand how each type of shingle works before selecting one for your home.

The most popular type of shingle is the asphalt shingle. It is lightweight, affordable, and durable. Asphalt shingles are coated with mineral granules that help protect the roof from the sun’s ultraviolet rays and increase its resistance to fire. These granules are typically colored to reflect the sunlight and enhance a roof’s visual appeal.

Shingles are typically manufactured in one of three ways: organic, fiberglass, or metal. Organic shingles are made from recycled paper with an asphalt coating, while fiberglass and metal shingles are composed of two layers that are bonded together. The type of shingle you choose depends on the region where you live, as some varieties are better suited for certain climates than others.

Aside from material, shingles are also designed with specific features in mind. For example, some are reflective to minimize their energy consumption, while others are rated for impact resistance. Additionally, some types of shingles are treated for algae resistance or mold and mildew protection.

Most shingles are bonded to one another at the time of manufacture using a thermally activated asphalt sealant that is positioned in spots on the top surface of each shingle. This enables installers to “stick” the shingle to the roof by driving nails through the tar-lined area, called the nail line.

There are a variety of shingle options on the market, but the most common are three-tab shingles. These are single-layered shingles that offer an affordable option that still provides decent wind and weather resistance, but they also have shorter service and warranty periods than other shingle types. Another popular option is architectural shingles, which are multi-layered shingles that replicate the look of natural wood shake roofing or slate tile roofs.


Tiles are a versatile building material that come in a wide range of sizes, shapes, colors, and materials. They are used for both decorative and functional purposes, such as on walls and floors. Tiles can add a unique and interesting design element to any home, and they can also provide a durable and water-resistant surface covering for walls and floors.

Tile roofing is a common option for many homes. It is popular because it offers a great deal of flexibility and style while still providing a durable roof that can withstand severe weather. There are several types of tiles, including terra cotta, concrete, metal, and plastic. Many clay tiles are coated with a waterproof glaze.

Roofing tiles are generally hung from a wood framework called a truss system, or they may be laid on a concrete substructure. The tiles are fastened by nails or clips. Flashing is often installed at field tiles, and it is also used at penetrations such as plumbing stack pipes, combustion vents, skylights, etc. It is important that all flashing be properly secured to prevent rainwater from seeping into the home.

There are a number of different tiles to choose from, and each has its own advantages and disadvantages. For example, ceramic tiles are quite durable, but they are not as effective in colder climates. Concrete tiles, on the other hand, can withstand very cold temperatures and are a good choice for most climates.

Another consideration is that roof tiles can be very heavy, and they require a structurally sound roof to support them. In addition, they can be expensive to install and replace.

When choosing a tile for your roof, it is best to consult with an experienced roofer. They will be able to help you find the perfect tile for your home, and they can recommend the proper installation procedures. In addition, they can explain the advantages and disadvantages of each type of tile and help you decide which is the best fit for your home. They can also assist you in making a budget and planning out your costs.


Metal roofs are made of a wide variety of materials, each with its own strengths and weaknesses. These are primarily related to the metal itself, its ability to resist corrosion and impermeability to water, and its appearance and durability. Some metal roofing is bare or unpainted, while others are colored or coated with a wide range of materials, including zinc, aluminum, galvanized steel, stainless steel, and copper.

The most common type of metal roofing is corrugated galvanized steel, which is a wrought iron-steel sheet that’s been coated with zinc before being roll-formed into corrugated panels. This coating helps protect the steel from rust and other environmental elements. Another option is galvanized steel, which combines a layer of zinc and aluminum with a galvanized steel core to provide added protection. Some manufacturers also use zinc-coated aluminum, which is sometimes known as “weathering steel.”

A key concern with both galvanized and galvalume steel is that their outer layers will corrode if they come into contact with certain other materials, especially copper, lead, wood, brick, or treated lumber. This can cause the structural integrity of the roof to be compromised, and in severe cases, it can result in the deterioration or failure of the entire system.

Lightweight and rustproof, aluminum is a good choice for acidic environments or coastal climates where salt air corrosion may be an issue. However, it dents more easily than other metals, so it’s not recommended for structures that will be subject to hail damage. Like other metals, it can be coated with high-performance coatings to improve its longevity.

Flat Roofs

Flat roofs have become more common in recent years thanks to ever-improving waterproofing materials. They are ideal for drier climates and can help cut energy bills by reflecting sunlight. They’re also easier to install solar panels and other green roofing elements on. Flat roofs can also provide extra space that’s useful for things like storage or lounging.

There are many different types of flat roofs and materials to choose from. The most traditional is the built-up roof (BUR), which is a multiple-layer system of felt and asphalt that’s often covered with gravel. It’s a classic, affordable choice that can last 30 or more years with regular maintenance. However, it requires professional installation and may emit harmful fumes.

A less conventional option is PVC, which has a rubber membrane with a plastic-like surface that’s highly resistant to sunlight and UV rays. It’s also watertight and easy to clean, but it’s more expensive than other flat roofing options. Another popular option is TPO, which uses polymers to create a durable, waterproof membrane that’s lightweight and comes in large sheets. It’s easy to maintain and a great choice for commercial properties.

Finally, a newer alternative is the “green” or “living” roof, which is a rooftop planted with grass and other vegetation. It’s a great way to reduce energy costs, lower the building’s environmental impact, and add a beautiful natural feature.

While it’s important to understand the benefits and disadvantages of each type of flat roof, the final decision is up to you and your roofing contractor. The right roofing material for your home will depend on geography, budget, and use. Proper design and regular maintenance will ensure that your flat roof performs well for as long as possible.
