Is your roof sloping or flat?

As mentioned in our article comparing metal roofing and torch down roofing, if your roof is gently sloping or flat, then the torch down roofing technique will be the preferred option. On the other hand, if you have a steeply sloping roof, then the aluminum roof will prove to be a better option.

Advantages Aluminum Roofing Has Over Torch Down Roofing

The following are the advantages aluminum roofing has over torch down roofing:

  1. Roof Installation: As expected, the aluminum roofing option is easier to install compared to torch down roofing. However, if you are not planning on doing it yourself, then that should not matter. Although, you need to bear in mind that the torch down roofing technique is best done by a professional. Do not go for a roofing professional who does not have proper experience in installing torch down roofs.
  2. Maximum Shedding of Rain and Snow: Since aluminum roofs have a smooth surface, it is much better at letting snow or water slide down compared to a torch down roof. Moreover, torch down roofs are usually low sloping or flat, which means that water or snow will settle down on it a lot more easily compared to the angled aluminum roofs.
  3. Ability to Reflect Heat: Aluminum roofs are able to reflect sun rays, and that can effectively cut down on cooling costs by 10 to 25%.
  4. Ability to Withstand Coastal Climate: While other metal roofs are prone to damage from salt corrosion in coastal areas, Aluminum reacts with the air to form a coating of Aluminum Oxide, which makes it fully resistant to corrosion.
  5. Expected Life: Aluminum roofs can last ages if you do not live in an area which is prone to unforgiving hailstorms. They will typically survive 40 to 70 years.  On the other hand, torch down roofs can last up to 20 years.

Advantages Torch Down Roofing Has Over Aluminum Roofing

The following are the advantages torch down roofing has over aluminum roofing:

  1. Damage from High Environmental Stresses: Torch down roofing is a lot more weatherproof compared to aluminum roofs. Even though aluminum is a stronger metal compared to steel, it is surprisingly lighter. Hence, in areas with strong winds and hail, aluminum roofs can suffer irreparable damage
  2. Modifications: Just like other metal roofs, it is hard to make modifications to your aluminum roof once it has been installed. In the case of torch down roofs, you can easily patch new material around the modification, and your roof is as good as new.
  3. Low Repair Cost and Price: While metal roofs are usually costly to install and repair, you need to shell out, even more, for an aluminum roof.  Torch down roofs, on the other hand, are much simpler to repair and maintain. Moreover, the installation cost of torch down roofs is a lot less than aluminum roofs.


Installing a new roof is not something to be done in haste. There are many factors to consider, as is evident from this article. We suggest you weigh in all the different factors before zeroing down on your choice. If you have decided on fitting a torch down roof, do remember to hire a roofing professional who is experienced in installing torch down roofs.
