Roofs are usually considered either steep slope or low slope. Low slope roofs are those that form an angle smaller than 18 degrees.

Most residential roofs are steeply sloped or pitched. Low slope roofs are typically only found on commercial properties and buildings.

However, some homeowners do prefer low slope roofs because they tend to be less expensive than pitched roofs. They also give homes a unique look and allow for the installation of rooftop gardens and solar panels.

Unfortunately, low slope roofs require more maintenance work and can be prone to snow and water damage.

Building or renovating your dream home? Consider these advantages and disadvantages of having a low slope roof:

Advantages

• Cheaper to install

Low slope roofs don’t require as much roofing material as roofs with steep slopes, which is why they’re less expensive. This makes them a practical choice for larger homes and commercial buildings.

The cost of installing a low slope roof is also less than that for a pitched roof because it is easier to build. Roofers don’t have to lift large trusses to build the structure. Instead of laying down shingles one by one, roofing contractors just have to roll out and seal the roofing material for a low slope roof.

• Resistant to strong winds

One of the best reasons to install a low slope roof is to protect your home or commercial property from wind damage. Strong winds can cause significant damage to steep slope roofs. In comparison, the pitch of a low slope roof makes it inherently wind resistant.

• Maximizes space

If you choose to install a low slope roof, you can sit solar panels or the compressor of your split air conditioning units on it. You can also make it eco-friendly by turning it into a green or living roof. If the structure permits, you can take advantage of the full sun and grow vegetables and flowering plants in container gardens.

Disadvantages

• Few choices for roofing material

Steep slope roofs can be made with metal, wood, slate, or shingles. There are plenty of roofing material choices and you get to play around with different design elements. On the other hand, there are limited options for low slope roofs.

The reason for this is that water doesn’t easily flow off a low slope roof. On this type of roof, water can pool and soak between shingles, wood tiles, and similar roofing materials, causing leaks and water damage. Only sealed or membrane type roofing are suitable for low slope roofs.

• Prone to snow damage

On a steep slope roof, snow can slide down the sides. Meanwhile, a low slope roof tends to get smothered by snow, especially after a big winter storm.

Because snow stays on a low slope roof longer than on a pitched roof, there is a risk that the weight could cause strain and damage the roof structure. Homeowners will have to keep clearing the snow to keep this from happening.

Now that you know the pros and cons of a low slope roof, you can decide if this type of roof will work with the home you plan on building. Whether you opt for low slope or steep slope, the Roofing Vancouver BC team is happy to help you build your dream roof!
