Last week we started talking about dormer windows, their many benefits and why they might be a worthwhile investment. This week, we’ll take a closer look at the different types of dormer window and when you should contact a roofer.
There are a broad range of dormer windows available for homeowners to choose from. The dormer that you choose will depend on your taste, your needs, the age and style of your home and, of course, your budget, but the most common types include gable and hipped dormers, and flat-roof or shed-roof dormers.
Gable roof dormers have a triangular roof shape and are probably what springs to mind when you think about dormer windows. They are attractive and tend to suit older, more traditional homes. Hipped dormers are similar, but they have slopes on three sides. They are more complex to build but look great.
Flat-roof dormers are common in loft conversions. They’re great for adding extra headspace and are the classic dormer that we tend to think of when referring to dormer bungalows. While flat-roof dormers are at risk of debris accumulating on top, shed dormers are a useful alternative. They offer the benefits of flat-roof equivalents, but their sloping roof means that less debris is likely to settle, making it ideal for larger projects.
Adding a dormer window is not a basic DIY job. It involves structural changes, roofing work, insulation, and potentially planning permission. Here’s when to call in a professional:
Early planning
A specialist can assess your roof structure, determine feasibility, and help design a dormer that meets building regulations and enhances your home.
Planning permission guidance
Some dormers fall under permitted development, but others, such as those on the front of the house, larger extensions, or if you live in an older home, require planning approval. A professional can guide you through this.
Structure and safety
Changing your roof structure has load-bearing implications. A structural engineer or experienced builder must ensure the work is safe and compliant.
Cost and design
A dormer project can range from £5,000 to £25,000+ depending on complexity. A specialist can give realistic budgets and timelines.
If you’re considering a full loft conversion, the dormer is usually just one element; a loft conversion specialist can coordinate the entire project to make sure that the project runs smoothly. Even if you’re adding a dormer window to an existing space, professional advice could save you a considerable amount of time and money in the longer term.
Whether you're dreaming of a new home office under the eaves or planning to convert your attic into a bright spare bedroom, a dormer window could be the key; but make sure it’s done right.
