Torch down roof- also acknowledged as “torch on roofing”- is one of the most standard roofing types for flat and slightly sloped ceilings. Torch-on roofing consists of multiple modified bitumen membranes used with a propane torch. This installation procedure presents torch-down roofing with a uniquely watertight seal, making it a superior choice for homeowners whose serious concern is water damage. This waterproof seal, along with several other advantages offered by torch-down roofs, makes it a prevalent option for homes having flat roofs.
However, torch-down roofs aren’t for every homeowner or every home. If you’re trying to determine whether a torch-down roof is appropriate for your newly constructed home, continue reading. We’ll cover everything you must be conscious of below if you’re considering such roofing for your home.
The Application Of Torch Down Roof
Two-layer and three-layer torch-on roofing systems feature the same base & mount elements laid in the same order. The written-below are the steps we, your local commercial roofing contractor, take to execute torch down roofing installation:
Step 1: Attach Insulation
Insulation is meaningful in freezing climates, but it’s an indispensable component of any flat or low-sloped roofing system. Insulation may be affixed with screws & plates, or it may be attached with glue, and this relies on the kind of roof deck and different factors of your home.
Step 2: Lay Down A Moisture Barrier
On the insulation’s top, the roofing contractor at Proper Roofing Limited will lay down a vapor barrier to help regulate condensation in the new roofing system.
Step 3: Establishing The Overlay Board
Next, the roofing contractor will position an overlay panel in place, which will act as a mounting surface to which the torch-down membranes will be attached. This step demands precision to ensure the overlay board is perfectly installed. Otherwise, you may end up having a roof that isn’t level, forcing water to pool.
Step 4: Laying The Base Sheet
Subsequently, your contractor will spread the first layer of torch down roofing material. They may fasten the base sheet to the overlay panel employing a heat fusing technique or an adhesive.
Step 5: Applying The Cap Sheet
Next comes the second coating of torch-on roofing material- the smooth cap sheet. As this material sheet is rolled out above the base sheet- the roofer will heat the cap sheet material’s bottom with a torch. The heated cap sheet is pressed below the base sheet, and the two will merge and form a waterproof seal. Establishing a two-layered torch down roof is the last layer of rolled roofing material your Proper Roofing Limited contractor will apply. In the event your home needs to install a three-layer torch down roof, the contractor will prepare the third layer with a granulated surface in the same manner.
Step 6: Install Flashing
After laying the rolled roofing, the procedure is almost done. Your contractor will apply the flashing near components that penetrate the ceiling to finish up.
Advantages of Torch Down Roofing
Here are some pros of torch-down roofs:
Water Resistance
The primary job of any roof is to keep moisture and water away from the building below. In the case of flat roofs, this job becomes much more challenging to do. This is notably correct in locations where snow builds on the top of the roof and melts off pretty slowly. The heat-sealed seams, along with ultra-waterproof membranes, make torch down roofing one of the most appreciatively water-resistant flat roof systems.
When established accurately by a professional, a torch-down roof deters water from accumulating and pooling on the top and facilitates drainage. Torch-down roofs are also immaculate for protecting homes from snow buildup damage, including dampness and mold development.
Flexibility And Durability
One significant advantage of torch-down roofs is their flexibility. The modified bitumen sheets have kinetic energy that expands and contracts as the climate changes without cracking. Torch-on material roofing works well in any environment where all other roofing materials are rigid and get damaged because of temperature alterations. This flexibility is what makes torch-down roofs durable and long-lasting.
Energy Efficiency
Precisely with the added cap layer in three-layer roofs, torch-on roofing safeguards against UV rays and heat. The torch-down roof surface can help reduce your energy bill in hot weather.
Lifespan
A torch down roofing lifespan is one of its main selling points, at 15 to 20 years. Torch-down roofs are additionally long-lasting than other types of flat roof systems available in the market, and this is because of their flexibility in hot & cold temperatures and their resistance to water damage.
Fire Resistance
With a granulated cap layer, torch-down roofs are able to be highly fire-resistant.
