What is a Commercial Roof?

A commercial roof is the exterior covering of a building that protects the interior from weather and other external factors. Roof installation is a big decision for any structure, primarily commercial buildings. There are many factors to consider, such as the type of roofing material, the number of layers, the pitch of the roof, and more. Your building type can affect what roofing material is best for your facility. Along with protecting your building from the elements, roof installation also helps in saving energy by keeping the indoor temperature consistent. The roof of a commercial building is typically made from asphalt shingles, metal, tile, or a synthetic alternative to asphalt shingles like fiberglass or slate tiles. Roof installation is a big job, so hire a professional contractor to do the work. For example, installing a commercial roof can include various tasks such as removing the old roof material, installing roof flashing, installing roof vents, installing roof shingles, and more.

Types of Commercial Roofing Materials

Before choosing a commercial roofing contractor, one must understand the different materials available. The three most popular materials for commercial roofs are asphalt shingles, metal, and tile. Additionally, synthetic materials like fiberglass and slate tiles are becoming more common. Each type of material has its advantages and disadvantages, and some are better suited for certain climates than others. Asphalt shingles – Asphalt shingles, or “AS” for short, are the most popular type of commercial roofing material because of their versatility, durability, and cost-effectiveness. They come in many shapes, colors, and sizes to suit any building’s aesthetic. AS roofs are made of three layers – the base layer (or “underlayment”), the granular layer, and the upper layer. The upper layer may be made of fiber, minerals, or asphalt. Metal – Metal is another common material for commercial roofs. You can choose from various colors and finishes, including copper, zinc, and aluminum. While it can be more expensive than asphalt shingles, metal is long-lasting and rust-resistant. It also does not require any underlayment. Tile – Tile roofs are a popular choice for commercial buildings in coastal areas because they’re water-resistant. They are also suitable for high-elevation buildings and rugged landscapes. Tile is available in various colors and styles, from ornamental to flat roof tiles. Synthetic materials – A synthetic roof may be the best option for extreme climates, like those in the desert or high-elevation areas. Artificial materials are often used in commercial roofing because they are energy-efficient, lightweight, and affordable. Common synthetic roofing materials include Ethylene-vinyl-acetate (EVA) and polyolefin.

How to Choose the Right Commercial Roofing Contractor

When choosing a commercial roofing contractor, finding a company that can meet your needs is essential. You want a contractor you can count on to do a quality job and stand behind their work. Finding a contractor that’s right for your project can be challenging. You may not know where to start or what to look for. Here are a few questions to consider when hiring a contractor for your commercial roof installation: – What education and certifications do they have? – Make sure any potential contractors have the required licensing and certifications for your project. You can search for your state’s licensing board to see if there are any contractors in your area. You can also find licensing requirements for your project type at the local or state building departments. – What type of warranty is included with the installation? – Warranties are essential for commercial roof installations because you want to be sure the contractor will be on call if any issues arise. You want a warranty that covers the entire life of the roof. – Can they provide references? – References can be a great way to learn more about a contractor’s work and customer service. Ask to speak with a few references, and make sure they are people in a similar business and industry you can relate to. Take the time to call the references and ask them important questions. – How long have they been in business? – Make sure you choose a commercial roofing contractor that is reputable and trustworthy. If they have been in business for a while, it can be a good indication of their quality of work.

What to Expect During The Installation Process

Installing a commercial roof can vary depending on the type of roofing material, the building’s design, and the contractor’s procedure. Here is a general overview of how the installation process might play out:

Roofing Material Selection

The contractor will come to your building and measure the roof. They may also have you choose the type of roofing material you want. Make sure to pick something that suits your building’s needs and aesthetic.

Roofing Flashing Installation

Flashing is an integral part of roof installation. It protects your building from water damage, especially if you are installing an asphalt shingle roof. Flashing is placed around the roof’s edges and underneath the roof’s first layer (the base layer).

Roof Vents Installation 

Roof vents are essential to roof installation because they help keep your roof cool. They also prevent the accumulation of snow and ice in the winter months. Make sure to discuss your ventilation needs with your contractor so they can install the proper vents for your roof. –

Roof Shingle Installation

The final step in the installation process is placing the shingles on the roof. The shingles are attached to the top using nails or staples.

Preparing for your Commercial Roof Installation

Before the installation begins, you must ensure your building is ready for a new roof. You can achieve this by performing a thorough walk-through of the building with your contractor. During this walk-through, you can identify potential issues and work with the contractor to correct them. Ensure your walk-through is thorough and accurate, as any problems you miss could return to haunt you. Besides inspecting the condition of your current roof and building, you also need to ensure enough room for the new top. Roof installation can be difficult and dangerous if there isn’t enough room to work. Depending on your building’s design, you may need to remove or adjust a few things during the installation process to make room for the new roof.

The Importance of a Comprehensive Roofing Warranty

The roof is an integral part of your building and will likely outlast the rest of the structure for a significant period. A commercial roof can last anywhere from 15 to 30 years, depending on the material used and the area where it was installed. Roof installation is a big decision, and you want to ensure it lasts as long as possible. A warranty can provide you with peace of mind and help prevent costly repairs in the future. There are different roofing warranties, including manufacturer warranties, distributor warranties, and contractor warranties. As a business owner, you want to make sure you choose a company that offers a comprehensive warranty that includes labor and materials. Make sure to read the fine print to understand what your warranty covers. A commercial roofing warranty can help you save money and ensure the roof is installed correctly.
