Most Common Flat Roofing Types Installed and Repaired in Central Ohio
Flat roofs come in many different shapes and sizes, but they can be broken down into five main types. This article goes into detail about each type so that when the time comes for a repair job on your flat roofing system, you have better understanding of the roof types.
Built-up roofs are the oldest type of flat roofing and are still installed today. They consist of multiple layers of tar paper and asphalt that are applied one on top of the other.
The number of layers used can vary, but three is the most common. Built-up roofs are very durable and can last up to 20 years, but they require a lot of maintenance and are not very resistant to leaks.
Easy maintenance of the built-up roofs requires regular inspection and repair of seams and flashings. The tar paper can also be torn by wind or hail, so it's important to keep an eye on it.
Single Ply Membrane Roofs
Single-ply membrane roofs are the most common type of flat roofing system and account for more than half of all new flat roof installations. They are made up of a single layer of waterproof material, such as TPO, PVC, or EPDM rubber. Single-ply membrane roofs are very durable and can last for up to 25 years with minimal maintenance.
If you want your single-ply membrane roof to last longer, you should inspect the roof at least twice a year for signs of damage or wear. A leak can usually be fixed with a simple repair kit.
Modified Bitumen Roof
Modified bitumen roofs are a popular choice for commercial and industrial buildings. They consist of asphalt that has been mixed with rubber or plastic, which gives it more flexibility and makes it resistant to tears and punctures. Modified bitumen roofs usually last for about 15 years, but they require more maintenance than other flat roofing systems.
More maintenance means that you should inspect modified bitumen roofs three times a year for signs of damage or wear. You can repair most minor damages with an adhesive, but major repairs might require replacing the shingles.
Rubberized Asphalt shingle Roof
Rubberized asphalt shingle roofs are a newer type of flat roofing that has been gaining popularity in recent years. They are made up of rubber and asphalt blended to create a durable, weather-resistant roofing system. Rubberized asphalt shingle roofs usually last for about 20 years, but they require more maintenance than other types of flat roofs.
You should inspect rubberized asphalt shingle roofs for signs of damage or wear at least twice a year. You can repair minor damages with an adhesive, but major repairs might require replacing the shingles.
Metal roofs are the most expensive flat roofing choice, but they are also very durable and require almost no maintenance. They consist of panels made from either steel or aluminum that have been coated with a layer of rubber to protect them from rust and corrosion. Metal roofs usually last for at least 25 years without needing any repairs or replacements.
For the metal panels to last longer, you should inspect metal roofs at least four times a year for signs of damage or wear. If there is an issue, it can usually be fixed with rust-preventing paint or rubberized coating.
Each type of flat roofing has its own advantages and disadvantages, so choosing the right one for your building is important. If you're not sure which type is best for you, consider getting help from experts at a roofing company who can help you make the right decision.
