A torch down roof is one of the most common types of roofs, especially for low sloped or flat roofs. Torch down is essentially built up or modified bitumen roofing. Discover the basics, prices and advantages.

Torch Down Roof Basics

A torch down roof is made of layers of fiberglass, polyester, and bitumen. This mixture is then layered between layers of asphalt and gravel. This layering takes place on site to ensure that the product covers every inch of roofing. To seal these different layers together, installers will use giant blow torches to create a watertight seal. This is where this type of roofing gets its name. The final result of the vulcanization with the blow torch is a strong united fiberglass sheet. The life span is about 20 years, and it requires less maintenance than traditional tar roofing. The final product is also much nicer looking than tar and gravel roof.

Torch Down Roof Cost

When compared to traditional asphalt roofs, torchdown roofs are slightly more expensive. With that said the more money you spend, when compared to traditional asphalt roofs, will be made up in the repairs you will not have to pay for. And they save money in the long run with lower maintenance costs. Installing a torch down roof now will save you more money in the long run, so it is definitely something to consider if you have asphalt roofing. More on torch down roofing cost.

Advantages Of A Torch Down Roof

Very Durable
There are many different advantages to using a torch down roof. They way it is layered creates both a strong and flexible product. It can move and shift without cracking or breaking; that means in extreme weather the roofing can flex instead of failing. While a torch down roof will flex in very extreme weather, conditions with heavy rain or snow may create too much added weight. The weight of water may cause the roofing to fail and collapse in on itself.

Water Resistant
While roofing can be extremely flexible, it is also extremely water resistant and durable. Since a torch down roofs is applied in layers, you can choose how many layers you wish to apply. Two-layer roofs will last about 10-15 years. If you choice to just add one extra layer, three total, you can expect the roofing to last around 20 years. Moreover, since a torch down roof is just a combination of asphalt and synthetic rubber and fiberglass, they are very easy to take care of.

Disadvantages

It is important to know that this type of roofing is not suitable for areas that are prone to high rain and snow fall, because it cannot drain water efficiently. This would lead to water pooling or snow piling up on roofs, increasing the weight and possibly causing damage to large section of it.

Maintenance

Maintaining a torch down roof is very simple. Since it uses a torch rather than a hot mop, there are not any dangerous odors associated with repairing or installing this roofing. The hot mop method of making other asphalt roofs emits dangerous flumes that can actually be hazardous to your health. This is why people normally have to move out of their homes while reroofing tar roofs.

The roofing comes in sheets, making it easily replaceable. On the rare occasion that there is a leak or gap in your roofing all you need to do is apply a sheet and reseal it. This makes any repair a very simple process.To add even more protection to your roofing you can choose to wait a month or two before adding a top layer of sealant. This will add even more protection. Coating your roofing will also add extra water and fire proofing capability. All the coating consists of is asphalt that is layered over the existing roofing.
