When you’re looking for roof repairs or even a replacement, it’s best to know as much as you can about the different types of roof. It’s no good basing your search on what you know about commercial roofing, for example, when you need a new roof for your three-bedroomed semi.

In this post, we’ll explore some of the key differences between commercial and domestic roofing, and the materials used for both.

Comparing the roofs

The differences in roofing for commercial and domestic properties stem from some key variations in the types of roof associated with these buildings.

The vast majority of domestic properties have pitched roofs. This is the most effective roof structure as it naturally lets water run off its surface. It’s also useful as it offers a bigger roof space, which can be used for storage or converted into an additional bedroom, for example. Pitched roofs are also a practical option for domestic properties because they’re generally less than 2,000 square feet in size.

In contrast, commercial roofs are typically much bigger than those on domestic properties. That makes it more difficult and more expensive to install a pitched roof for the entire surface. In many cases, the best solution is a flat roof. This allows you to cover much more surface area at a lower cost.

All that said, there are many commercial properties, like domestic-to-commercial conversions, with pitched roofs. Likewise, lots of domestic properties will have a flat roof on their garage or extension.

How the materials differ

Pitched roofs on domestic properties will generally use clay tiles, concrete tiles or slate. Slate is naturally non-porous, while clay and concrete are heated to become hard and water-resistant. This works with the slope of the roof to allow water to run straight off and into the gutters.

Given that most commercial roofs are flat, however, they don’t use tiles or slate. For one, because these materials would leave a lot of weight sitting on the roof’s surface. But also, because the cost of these materials would soon stack up over a larger surface area.

Instead, flat roofs have a range of coverings, from bituminous waterproofing to more robust single ply flat roof membranes and GRP (glass reinforced plastic) systems. These materials are designed to maximise water resistance without too much concern for the style.

Understandably, bituminous materials or single ply membranes aren’t suitable for most domestic roofs as they are designed specifically for flat roofs. However, they can be used on extensions or even modern domestic properties which are built with a flat roof.
