Types of Roofing

A roof is a protective covering that shields the interior of a building from rain, snow, sunlight, and other weather elements. Roofs can be built in a wide variety of styles.


Before starting a roofing job, it is essential to have accurate roof measurements. This can help with bidding jobs, ordering materials, and determining square footage. Contact Corpus Christi Roofing CO for professional help.

A roof’s underlayment system provides an extra layer of protection against water damage, enhancing the lifespan and performance of your roofing materials. This system is a critical component of any roof, especially in areas prone to heavy rainfall and extreme weather conditions. Without an underlayment system, moisture could leak into the interior of your home, causing costly repairs and even mold growth.

There are several different types of roof underlayment available, including felt, synthetic, and rubberized asphalt. Felt underlayment, made from varying blends of polyester and natural plant fibers, was the traditional choice for roof underlayment until about 15 years ago when synthetic products gained popularity. Felt underlayment comes in two options: 15 lb felt rolls and 30 lb felt rolls. 30 lb felt is thicker and stronger, making it less likely to tear during installation.

Synthetic underlayment is a more recent innovation, utilizing polymers to create a lightweight and durable material that is both highly resistant to moisture and wind-driven rain. It is also able to withstand high heat and cold, and it’s designed to be compatible with most roofing materials. Synthetic underlayment is more expensive than other types of underlayment, but it can significantly reduce the risk of leaks and moisture damage.

Rubberized asphalt underlayment, which combines asphalt with rubber polymers to create a self-sealing material, is another new option. This type of underlayment can be used to help protect the roof from water penetration in leak-prone areas, such as around eaves, valleys, vents, chimneys, and skylights. Its waterproof properties and non-skid surface make it easier for roofers to install, reducing the chance of injury.

Regardless of which underlayment material you choose, it’s important to follow all manufacturer recommendations and local building codes to ensure proper installation. In addition, consider the climate and building design when determining whether or not underlayment is necessary for your roof. Consult with a roofing professional to determine which type of underlayment is best for your project. Once your underlayment is in place, it’s time to start the shingle installation process! Before laying shingles, remove any debris or dirt from the roof deck. Once the roof is clean, lay your underlayment starting at the eaves.


Unlike the other roofing materials, which are installed as separate layers, shingles are one layer that’s layered directly over the roof deck. There are many different shingle types on the market, each designed to meet specific weather conditions and roof structure characteristics.

Traditional paper or fiberglass asphalt shingles are the most common, but there are also composite or synthetic shingle options. These are engineered to mimic the look of natural wood, slate or clay shingles while adding improved durability, strength and resistance to weather elements.

Shingles come in a variety of shapes, sizes and colors, including some that reflect heat from the sun and may help reduce energy costs. There are also specialty shingles for different regions and climates that feature features like rubber to resist hail damage, reflective granules to lower home cooling costs and algae-resistant shingle coatings.

In most cases, shingle installation is straightforward, with each course of shingles being placed next to the previous one to cover roof edges and provide water-shedding coverage for the whole roof surface. But some shingle designs require unique application methods. For instance, architectural shingle types like IKO’s Armourshake have intermittent lower exposed tabs that need an additional starter strip shingle course in matching color to cover them.

When it comes to valleys on the roof, experience professionals recommend installing a metal flashing in addition to the standard shingle system. This is because water that pools in a valley, particularly when the roof is warmer than the air in winter, can freeze as it flows down the shingle slopes and then back up underneath them, leading to cracking and leakage into the home.

To prevent ice dams, which are formed when melted snow runs down the roof to the eaves, and then freezes again, forcing water up under the shingles, install an ice and water membrane to protect these areas. These rubberized membranes seal around the shanks of the shingles and provide an extra layer of water-shedding protection.


Slate is a natural, aesthetically pleasing, and long-lasting roofing material. It is available in a wide range of thicknesses, widths, and colors, and it can be cut into uniform tiles or shingles. A wide selection of slating styles has evolved over the centuries in response to local requirements or availability, as well as architectural preferences.

A slate roof can add a distinctive look to your home, but it can also be a costly investment. Fortunately, the longevity of slate roofs means you will likely never have to replace it during the time that you own your home. This makes it a worthy long-term investment.

Slate is derived from metamorphic rock that changes in form under the influence of heat and pressure. Slate occurs in a variety of colors, which are influenced by its mineral composition. For example, hematite gives it purple tones, chlorite creates green, and carbon produces black and gray. Slate is durable, watertight, and has low water absorption. It is highly fire-resistant, and it is not prone to breaking from exposure to freezing temperatures.

Because of its durability and beauty, slate is used to roof churches, universities, and government buildings. It is also a popular choice for historic homes and commercial structures.

When installing a slate roof, it is important to follow the proper guidelines. Ensure that the headlap and sidelap are correct, and that each slate is securely fastened. The slating pattern and color should match the architectural design of the building. It is also recommended to use a pre-punched hole for each nail. This will prevent the slate from slipping when it is installed on the roof. Lastly, ensure that the gable ends overhang the roof edge by about 1 1/2 to 2 inches.

Since slate is fragile, it is best to install a slate roof with the help of an experienced roofing contractor. It may be difficult to find contractors that know how to properly install a slate roof, so you may pay higher service fees or have fewer options when hiring a professional to work on your slate roof.


Metal roofing has long been a popular option for commercial buildings and is now growing in popularity for residential homes as well. It is durable, long-lasting, and can add a modern or rustic look to the home’s architectural style.

The most common type of metal roofing is steel. It comes in a wide range of thicknesses or gauges, and is commonly rolled into corrugated or ribbed forms for strength. Galvanised or galvalume steel is also used, and this option provides a layer of zinc to help extend its life and protect it from corrosion.

Another type of metal roofing is aluminum. This is typically less expensive than steel, but it can dent or rust over time. It can also have fewer color options than other metals. Finally, aluminum expands and contracts more than steel, so installers need to give it extra room.

Other types of metal roofing include copper and zinc. Zinc has a unique, natural appearance that can stand out in any neighborhood, while copper develops a green patina as it ages. This can be a drawback for some homeowners, as it can stain siding or brick, so it is often painted over.

The best metal for your roof will depend on the location and the stresses that it will face. Choosing the right material, along with experienced installation and proper maintenance, will keep your home safe and beautiful for decades to come.

Many people associate metal roofs with barns or industrial structures, but they are versatile and can be used on a variety of structures and architectural styles. They can even be designed to mimic the look of wood shakes or clay tile, so they blend in well with the rest of your home’s architecture. In addition, metal can be shaped to accent or hide the structural elements of your building. This can be done with standing seams, where the panels overlap each other, or a more contemporary look like a standing-seam wavy panel.
