Our Flat Roofing Process


At Niagara Roof Masters, we are dedicated to offering the best quality of service that surpasses the expectations of our clients. Whether you need a flat roof installation or replacement, we’ve got you covered. Here is a detailed explanation of the flat roofing process.

Removing the Old Roof

The first step in the flat roof replacement process is the removal of the old roof. Our in-house roofing team has the experience and equipment to safely and efficiently tear through every level of your old flat roof. Keep in mind that the removal process varies depending on the roofing material. Overall, the process involves the removal of the roofing membrane, metal drip edge, foam board insulation, and roof decking. While we try to recycle as much as we can, some of the components must be disposed of.

Evaluate for Damage and Handle Repairs

To guarantee lasting results, our flat roof installation process starts with decking inspection and repairs. We will repair any damaged or rotted decking. Any issue with standing water may require the removal of everything in that area. The goal is to ensure the old damages don’t recur once the new roof is installed.

Attach the New Flat Roof

Several steps are involved in flat roofing. The first step is to take measurements of the roof in order to purchase the right roofing material size.

Inspection of the Insulation

Our team will then scrutinize the insulation to determine whether you need new insulation or if the old one can be reused. Unless it is severely damaged or is too old, your old insulation can be reused in many cases. It is also important to note that not all flat roofing systems require insulation. We will let you know if the plenum between your ceiling and roof deck will be a sufficient buffer.

Base Sheet Installation

We will install an underlayment layer to guarantee leaks never get to the insulation and the decking layers. The base sheet serves as a water barrier that keeps the lower layers dry. The underlayment further offers fire protection.

Drip Edge Replacement

The drip edge is what directs water into the drains. It keeps the vulnerable areas free from water damage. Our team will custom-form the drip edge to fit your roof perfectly. The drip edge will be attached on top of the underlayment.

Torch-Down Membrane

The torch-down asphalt layer is what will seal the roof. It covers the drip edge. During the installation, our team uses propane torches to melt the rubber layer under the asphalt membrane so that it seals the underlayment tightly. Care is taken when working around the chimneys, vents, and skylights, as these are hotspots for leaks and damage.

Silicon Coating and Sealant

While it is optional, we recommend adding a silicon top coat over the torch-down membrane. The coat adds an extra layer of waterproofing as well as the benefit of UV reflection, which keeps the roof cooler.

The flat roof installation process requires an experienced team to do well. We guarantee excellent work.

Why Flat Roofing?

Many commercial buildings have flat roofs or nearly flat roofs. The key benefits of flat roofing for commercial buildings include versatility, ease of maintenance, and considerably more energy efficiency compared to sloped roofs. So, why do commercial buildings have flat roofs? Here are the top reasons why it’s a good investment.

Flat Roofs Are Cost Effective

Compared to sloped roofs, flat roofs cost less to install and repair because of their less surface area that uses less material. Workers can also walk on them safely.


Flat roofs allow for the installation of air conditioning units on the roof. This not only keeps the HVAC units safe but also reduces the cost of pushing cold air upwards. The flat roof can further be turned into a storage space or a rooftop garden. They are perfect for solar panels too.

Why do modern houses have flat roofs? Here are other reasons:

  • High resistance to strong winds
  • Easy to access and inspect for damages
  • Easy to clean
  • Energy efficient because they don’t trap unwanted warm air
