TORCH DOWN ROOFING GUIDE: PRICE AND LIFE EXPECTANCY

There are different types of roofing available for buildings. Some of them are

  • Metal roofing,
  • Solar tiles roofing,
  • Asphalt shingles roofing,
  • Green roofs,
  • Clay and concrete tiles etc.

The roofing of a building depends on many factors like the topography of the area, the climate of the region, types of natural phenomena likely to happen in part etc. For example, the roofing in places like Canada, where snowfall happens, will be pyramidal for the snow to the dropdown. And in places like Japan, which is an earthquake-prone region, the roofing and the construction will be different from buildings in America.

Torch On Roofing

One of the standard types of roofing usually seen on flat or very slight pitch roofs is called torch down roofing. Its official name is “modified bitumen.” It is a rolled roofing method that has a tough membrane placed in a thick layer of asphalt. They are instead an old method of roofing. But it is still used because it’s cheap to install compared to other roofs.

Each torch down roof consists of bitumen, polyester, and fiberglass layers. The mixture of these is placed in between asphalt and gravel layers. A blow torch is used by the installer to make the layer stick together. They are made to be waterproof.

LIFE EXPECTANCY AND COST:

Most of the time, torch down roofs lasts up to 20 years. But the installation of this kind of roof can be hazardous and costs more than the conventional types of roofing. Even though the cost is high, its advantages like long life span and resistance to even harsh weather make it worth the price.

The average price of discounted torch down roofing ranges from 365$ to 460$ for 1200 square feet. If the materials are of superior grade, it can range from 850$ to 1075$. The high-cost torch down roofs has extra benefits like high-quality underlayment, better damage resistance, more demanding and thicker materials, longer life span, etc.

The cost of materials alone will be 1$ to 2$ per square foot. And the installation cost will be 2 to 4 dollars per square foot. The price is slightly more than an asphalt gravel roof. But the maintenance cost is low.

Since this type of roofing is made in layers, it is found to be more robust and durable. It can even survive in extreme weather conditions because the material used is flexible so that the roof can make slight movements without any cracks, breaks, or bents. But it is better not to use in regions having extreme snowfall or rain because of the weight of the snow or rain, and the roof can collapse.

The life span is about 15 to 20 years, which is greater than many other types of flat roofing methods. Some can even last up to 30 years, depending on the weather and maintenance. The longer life expectancy is mainly because of its flexibility and water resistance property.
