Pitched Roofs vs Flat Roofs
The choice of roofing covering will depend on the shape of the roof you choose for your garden office. Here is a brief overview including pros and cons of both roofing types to help you decide which is best for your structure.
Pitched roofs are a fantastic choice for those looking to create a more traditional look and can coordinate stylishly with classic style homes. When correctly fitted, they are extremely long-lasting with top weather-resistance and a robust build. Pitched roofs also drain rainwater easily thanks to the sloped design which prevents pooling and potential water damages. However, pitched roofs can often be more expensive and time-consuming to install which may be a factor to consider if you are looking to preserve time and money when building your garden office.
Types of Pitched Roofing
There are various pitched roof styles that are popular in garden office design. The most common is the apex or dual pitch roof which features two slopes that meet in the middle at the highest point. This design is great for water drainage, offers extra head space and creates a more traditional look for your office. Another popular design is the single slope or mono pitch roof which features a single slope, forming an incline with the highest point at one full length side. This roofing style creates a minimal, contemporary aesthetic and is also good for minimalizing weather damage caused by rainwater and snow.
With a more compact design, flat roofs are great for this kind of project. They create a modern aesthetic for your office plus are a more affordable option with quicker installation times. Although not to the same degree as pitched roofs, flat roofing also still incorporates a slight slope which allows rainwater to drain. The main disadvantage to flat roofs is that they can sometimes offer less durability than pitched roofs although with newer, more robust materials, correct maintenance and proper installation, the lifespan of your office roof can be easily extended.
Cold vs Warm Roofs
There are two main types of roofing insulating systems in flat roof construction which are named cold and warm roofs. Whilst they both achieve insulation; they differ in technique.
Cold roofs are often used in garden building design, most commonly with timber frame structures. With a cold roof structure, the insulation is placed between the rafters which is an easy, low-impact insulation method that makes use of unused space. The cold roof technique leaves an average 50mm gap between the top of the insulation and the above roof deck which allows air circulation whilst also allowing cold air to enter, hence the name ‘cold roof’. Cold roofs can be vulnerable to condensation build-up so suitable ventilation is required.
Warm roofs have now become much more popular in garden office designs as insulation covers the whole roof, leaving no ‘cold spots’. With a warm roof structure, insulation is laid over the top of the roof deck, on top of the vapour control layer and underneath the roof covering. This method keeps the entire roof structure warm, offering enhanced thermal insulation for the whole garden office. As the insulation is fitted on top of the rafters, there is also no problem in fitting recessed downlights.
The Best Roofing Materials for Garden Offices with Pitched Roofs
A hugely popular choice for garden offices, cedar shingles not only create a beautiful, natural aesthetic but are resilient, long-lasting and are supplied from sustainable sources with a low carbon footprint. They have a higher R value than other materials, meaning better insulation to keep your office warm in the winter and cool in the summer. Cedar roofs may require some easy maintenance and can be more expensive than other materials, but the extra cost is down to the practical and visual quality you can achieve. Something to note is that cedar shingles start out as a reddish brown colour and weather to a silver grey over a few years.

The only real disadvantages to metal sheeting are that it can be more expensive and isn’t invulnerable to some dents and scratches over its lifetime.
