Flat Roof Installation & Repairs

AngiYelpBetter Business BureauDiamond Certified

Flat roofing is popular among commercial and residential property owners. Deciding on the best option for the type of roofs can be challenging. However, many property owners select roofs with more benefits and that are also durable. Flats roofs are known to last longer when properly maintained with limited repairs.

Although they are economical to install, flat roofs require expert installation. Installation defects destroy the integrity of your roof and also cause damages to property under the roof. Hence, it is important to know about the types of flat roofs available and their benefits to make an informed decision.

Different Types of Flat Roofs

Thermoplastic Membrane

There are two types of flat roofs in this category: thermoplastic olefin (TPO) and polyvinyl chloride (PVC). Mostly they come in grey and white colors, although a wider variety of colors are available. They are made of a single-ply material and are attached using screws and plates during installation.

PVC is sturdy and flexible. Therefore, it is easy to install. It is also durable and can last more than 20 years.

TPO is an eco-friendly thermoplastic membrane and can be recycled when it gets old. The membrane contains flame resistant and UV absorption material.

It is difficult to distinguish the two thermoplastic membranes from afar. They are both popular due to their durability and ability to tolerate heat.

EPDM (ethylene propylene diene monomer)

This type of flat roof is made of a rubber membrane. It is white or black. Black-colored flat roofs are heat absorbent and require you to place an insulation board over the rubber membrane.

The roofs are either glued or weighed down using stones during installation. It is an inexpensive flat roof option and durable as it can last for almost 30 years. EPDM is also easy to maintain.

Modified Bitumen

Modified Bitumen roofs contain asphalt rolls. The roofing has several layers with the inner insulation and a topcoat layer. It is durable and easy to repair.

The flat roof installation process involves the use of heat materials and some adhesives and preferably best done by a professional for both installation and repairs.

Build Up Roofs

Build up roofs, also referred to as BUR, are easy to spot due to their gravel exterior. Just like modified bitumen, they are asphalt-based. After a few hot tar layers, the flat roof is covered with gravel.

Benefits of Flat Roofs


If you are looking for an investment to serve you for extended periods, flat roofs are your best option. Flat roofs are made to withstand harsh weather and also offer protection against UV rays. When flat roof installations are done the right way, they last between 20-40 years, depending on the material.

Economical to install

The surface area to cover is reduced and therefore, the materials bought and labor acquired is also limited. Property owners, therefore, incur less installation cost compared to pitch roof installation. Also, flat roof installation and repairs materials are relatively cheaper in the market.

Effective use of space

The top surface of a roof is used for different purposes. In many commercial buildings, property owners place solar panels on top of the roof to supply energy and reduce electricity bills. A garden, a patio, lounge are among the creative ways people utilize the top roofing space.

Low maintenance roofing and minimized repair requirement

Due to the strength of the material used, the roof stays in good condition for extended periods. Therefore, flat roof repairs services are not required as often. Maintaining a flat room is quite easy and cost-effective. 

The installation of flat roofs is the most crucial part of the roofing process. A strong base will ensure that flat roof repairs are eliminated, and all the benefits are enjoyed successfully. Besides ensuring your roof has no defect, experts also provide advice to help you decide the correct type of roof for your building.
