Why Roof Pitch Matters

Posted on: 6 February 2018

Do you know the pitch of your roof? This is something which most homeowners have no knowledge of, despite the far-reaching influences it has on the roof. Here are some of the reasons you should understand your roof's pitch:

It Determines the Best Material to Use

Most roofing materials can be used on almost all kinds of roofs, but there is always the best material to use depending on the roof pitch. For example, a low pitch means slow water drainage, which means the material used on such a roof must be able to withstand the effects of water. That is why conventional shingles are rarely used on flat roofs; the water would have all the time it needs to soak between the shingles and damage the roof.

It Determines the Drainage System Design

High-pitched roofs do not need extra drainage installations to drain away the water because gravity will take care of the water drainage; you just need to install strong gutters and proper downspouts, and you are good to go. A flat roof, on the other hand, cannot rely entirely on gravity to get rid of water that may fall on it. For example, a flat roof may require aluminum or copper inserts on some areas to collect and get rid of water that may pool on the roof.

It Determines the Size of the Attic Space

If you are interested in the volume of your attic space, then you cannot afford to ignore the issue of roof pitch. As a general rule, the higher the pitch of the roof, the more space you have for your attic. This can be of great use to you if you want to use the attic as an additional storage space.

It Determines the Necessary Maintenance Practices

The type of maintenance a high-pitched roof requires is different from the maintenance a flat roof requires. This is because roofs of different pitches experience different problems. Here are some of the common problems that are more common with low-pitched roofs than high-pitched ones:

  • Snow accumulation
  • Water ponding
  • Water leaks
  • Shingle blistering

It Determines the Danger of Working on the Roof

Lastly, the pitch of the roof also determines how safe or dangerous it is to walk on the roof. As a rule, walking on a high-pitched roof is dangerous because you can easily slip and fall. However, walking on any type of roof isn't advisable because you can damage the roofing materials even if you don't get hurt.
