Popular in the 1970s, cathedral roof trusses are making a comeback, especially in cottages and country homes. Many people are now choosing to build their homes with this type of roof truss.<\/span><\/p>\n

In this article, we take a look at what you need to know about cathedral roof trusses<\/a> before making your choice.<\/span><\/p>\n

Why opt for a cathedral ceiling?<\/span><\/h2>\n

A cathedral ceiling is easy to spot. It’s a ceiling with two matching slopes that follow the roofline. The beams may or may not be visible, but they typically create a high ceiling.<\/span><\/p>\n

The main reason to select this type of roof truss is for its visual appeal. It creates a sense of spaciousness and luxurious charm, particularly when paired with panoramic windows.\u00a0<\/span><\/p>\n

However, if you choose a cathedral ceiling, you should be aware of its potential drawbacks, which we’ll outline below.<\/span><\/p>\n

Disadvantages of cathedral roof trusses<\/span><\/h2>\n

The aim of our article is to tell you everything you need to know about cathedral roof trusses, so that you can choose the right <\/span>type of wooden roof truss<\/span><\/a> for your project. We also believe it’s important to inform you about the potential drawbacks of this type of prefabricated structure. By choosing a cathedral ceiling, you may experience increased heating costs, water infiltration issues, and a higher risk of mold growth. Therefore, it’s important to select your contractor carefully.<\/span><\/p>\n

First drawback: heating<\/span><\/h3>\n

Because of the ceiling shape and the tall heights it offers, this type of roof truss requires a specific approach to the heating system.<\/span><\/p>\n

Most homes today use convection heating, which is not ideal for cathedral ceilings as the heat tends to rise and become trapped.<\/span><\/p>\n

As a result, you’ll need to heat your room much more to maintain a comfortable temperature. Moreover, you’ll require top-notch thermal insulation to prevent heat loss.\u00a0<\/span><\/p>\n

It’s recommended to install a radiant heating system in your home. If you’re currently building your home, you can plan for this type of heating system. However, if your home is already built, you’ll need to make specific modifications.<\/span><\/p>\n

Second drawback: insulation<\/span><\/h3>\n

This problem will mainly affect older buildings, but it’s an important factor to consider in new construction. In fact, insulation is even more critical for a cathedral ceiling compared to other types of ceilings.<\/span><\/p>\n

The shape of a cathedral ceiling can actually contribute to the formation of ice dams. When snow accumulates on the roof, ice can form and prevent subsequent snowfall from draining off. As the ice melts due to warm air leakage, it can penetrate your attic, leading to water infiltration and mold growth. Therefore, proper ventilation is key.<\/span><\/p>\n

There are two solutions to this problem:\u00a0<\/span><\/p>\n
