What is the torch roofing installation process like from start to finish?

The use of a blowtorch can be dangerous, especially for roofers not familiar with it. Many contractors’ liability insurance companies have specific exclusions in their policies for torch related accidents. After installing the vapor barrier, roofing professionals lay down an overlay board to provide support for the torch-down membranes. This helps prevent ponding and water damage.

Torch down roofing is a popular choice among homeowners who want a low-maintenance and durable flat roof for their homes. This type of roof has excellent water-resistant properties, especially if the insulation and underlayment are installed according to manufacturer application instructions. Your Bowie contractor will start by applying a layer of underlayment to your roof. This step is crucial, as if it isn’t done properly, water could pool under your new roofing system.

After laying the underlayment, your Torch Roofing contractor will apply the first layer of your torch down roof. This layer is rolled out and heated with a propane torch. The heat fuses the membrane to the overlay board, creating a waterproof seal. Your Bowie roofing contractor will continue to install the rest of your roof’s layers. Then, they will add the metal flashing to ensure your roof is leak-free. When they reach the edges of your roof, they’ll apply a special adhesive to the membrane and metal areas. They’ll also make sure to add the required patches around skylights, a/c unit curbs, and vent pipes.

Typically, the first step in any torch down roof installation is to lay down insulation. This is especially important for flat and low-slope roof structures to help retain heat inside the building or structure. After the insulation, a vapor barrier is laid down. This underlayment is important to prevent condensation and moisture problems. Then, your Bowie contractor will put down an overlay board or cover board. This acts as a support surface upon which the torch down membranes will adhere. This step requires precision, since an improperly installed overlay board can lead to a Barrie Roofing that isn’t level and may cause water pooling.

It’s important that you wear heavy-duty gloves and work boots to protect yourself from the flame and melted asphalt used in the process. It is also recommended that you wear a face mask to avoid inhaling fumes. After the base sheet is applied, your Bowie roofing professional will apply a cap sheet. A two-layer system will have a smooth cap sheet, while three-layer systems will include both a smooth and granulated cap sheet.

Once the underlayment is in place, roofing professionals will begin applying the torch down membrane. This is a rubberized material that comes in either smooth or granulated sheets. It protects against heat and sun rays, which can help reduce energy bills. Additionally, it is durable and lightweight. It is important for roofers to wear protective gloves and work boots during the installation process because of the flame and melted asphalt involved. They should also stay a safe distance from the flame and always be sure to have a fire watch person posted on site to immediately respond to any possible smolders or flare-ups.

As the roofers apply the membrane, they must heat it thoroughly with the torch to ensure that all areas are properly adhered. The roofing membrane can be inspected for adhesion by pressing down on the end overlaps and ensuring that there is a minimum of 3/8 inch bitumen flow out (see image below). If a bitumen seal isn’t created, the roof will likely leak.
