Flat Roof Installation 101

If you are thinking of installing a new roof and the term flat roof installation comes to your mind, then you’re in the right place! Flat roofs have been popular for centuries and are becoming more and more common as time goes on. When you think about flat roofs, you might envision the classic pitched roof style; however, this is just one of the many options available. In the following blog, you will get to know flat roofs, types of flat roofs, and their advantages so that you can make a better decision that fits your needs.

What Is A Flat Roof?

A flat roof is a design of roof that has no or little incline. Technically speaking, A flat roof house has a roof with no slope or a slope that is in the range of 10-14 degrees. This slope/slight pitch is made to allow water to drain from the flat roof. 

It is typically used for commercial and industrial buildings, but sometimes for residential homes as well.

Why Are Flat Roofs Popular? 

Flat roof installation is not only done in commercial buildings but in residential properties as well. Houses with flat roofs are also getting popular because of several advantages of these systems. Some of these are given below. 

Low Maintenance 

Since flat roof installation doesn’t have drainage systems like pitched ones, they require less upkeep than their counterparts. Flat roofs reduce maintenance costs considerably because there is no need to seal or re-seal the roof like you would with a traditional style of a shingle roof.

Also, repairs to a flat roof are also accessible. If there’s an issue with one part of this type of roofing material, then there’s no need to worry about replacing the whole thing; just fix that section!


The flat roof houses require less upkeep and repairs due to the fact they are highly durable in nature. They can protect your home as well as your business. Flat roofs can easily withstand all kinds of challenging weather conditions in Tampa, FL.

They will not need replacing or repairing as often as other types of roofs might need due to their ability to withstand heavy rains, snowstorms, hurricanes, etc.


Whenever we decide on the type of roof structure we will use, one major factor that plays a significant role in influencing our decision is the cost.

Another significant advantage of this system is that the flat roof installation cost is low. Flat roofing materials are more cost-effective than their sloping counterparts because they require fewer materials in order to create a durable structure.

Easier To Install

When it comes to roofing systems and their installation, commercial flat roof installation requires far less time to be completed because of the fewer materials required. Also, the labor costs are low. So If you’re looking for a roofing option that is quick to install and easy on you, plan on choosing a flat roof. With its simple design and fewer materials and pieces, your roofing project won’t cause any delays in your daily operations. You can focus easily on your business.

Environmentally friendly

It is vital for every business to reduce waste and contribute more towards the betterment of the environment. With flat systems, you can do your part. Flat roofs can be made from recycled materials like rubber. These materials do not degrade and will last a long time without needing replacement or repairs.

Types Of Flat Roof Installation

Commercial flat roof Installation in Tampa can be done with the help of many materials. Each of these materials has its own pros and cons and serves specific needs. Also, the installation process is different for every system. For example, flat roof EPDM installation is different from another material, say PVC. 

Some of the most popular materials used by flat roof installers are given below. 


EPDM is a type of rubber black, synthetic rubber that is installed in sheets and then applied with an adhesive. Short for Ethylene Propylene Diene Monomer, EPDM is one of the most common types of materials used for commercial flat roof installation. The EPDM that companies use consists of a single layer of synthetic rubber that has been reinforced with fiberglass or polyester scrim. 

The contractor can adhere the EPDM directly onto the roof deck or attach it with insulation boards underneath to create an air space between the roof deck and the EPDM membrane. The main benefit to using EPDM is its durability; it will last up to 30-50 years if maintained properly.


TPO (thermoplastic polyolefin) is a single-ply membrane that was developed in the 1990s. This has been treated with UV radiation-resistant materials and heat-sealed together. TPO membranes come in lighter shades, such as white and tan. This makes the material reflective, which helps keep your building cooler during the hot summer months. This flat roof installation is helpful in the hot weather of Tampa. 

The manufacturers make TPO with the help of rubber polymers with thermoplastic polypropylene added to it. This gives the material strength and durability. TPO roofs are lightweight too.

Modified Bitumen

The Modified Bitumen, also abbreviated as MB roofing system, consists of asphalt that is ‘modified’ with either a polyester or fiberglass mat. This makes it more durable and flexible without the need for heating to install it. The contractor will roll out the mats and then will attach them to the roof with an adhesive.

This type of flat roof installation system is very popular in North American commercial flat roofs. You can use this system on residential roofs as well. A key benefit to this type of roofing system is its durability and flexibility, allowing it to expand during hot summer days, effectively combating any issues with buckling or blistering. 

Built-Up Roofing

Built-up roofs, or BURs, are one of the oldest forms of flat roofing. They’re also referred to as “tar and gravel” roofs because they consist of multiple layers of asphalt and tar that are built upon your roof before being covered in gravel. The final result is a very durable surface that is made to withstand extreme heat and water damage. 

However, that durability comes at a price—BURs are the heaviest form of flat roofing and require significant structural support to avoid caving in under their own weight. 

PVC Roofing

PVC is an acronym for polyvinyl chloride. This material has become increasingly popular in recent years due to its versatility and durability. It is also not limited to one or two color options but a large variety of colors. PVC roofs can last up to 30 years before needing repairs or replacement, which makes them an excellent choice for both commercial and residential roofing applications. 

It’s also very easy to install and has some flexibility when it comes time for repairs or maintenance down the line. This can help keep costs low over time as well! However, its price is a little bit on the higher side. 

How Can You Maintain Your Flat Roofing System? 

Your job does not finish after choosing the perfect flat roofing system. You need to take care of it as well. Proper maintenance is important to ensure that your roof stays in its optimal condition. But how can you do that? Don’t worry. For your convenience, we share some tips to perfectly maintain your roof. 

Regular Inspection

The first step you need to take towards flat roof maintenance is to ensure that you inspect your roof regularly. It is thus, advisable to hire a professional roofing company for a thorough inspection. They are experts and can give you a better understanding of the potential issues (if there are any) and how you can take care of them.

Cleaning The Roof 

Since the roof is flat, it is difficult for unwanted objects such as tree branches, leaves, debris, or any other material to move from the roof. Thus you have to clean the roof regularly so that these items do not harm your roof. 

Check Its Drainage

Flat roofs are prone to ponding water due to the low slope. If the water stands for too long, then it can damage your commercial roof. If you see water pooling, then it would mean that something is not right with your drainage system. Unclog the gutters and remove the debris.
