Roofs are essential parts of houses because of their protection against rain, sunlight, snow, and wind. They keep homeowners safe during natural disasters. Aside from maintenance and repairs, one thing you can do to improve your roof is a roof extension. This article will tell you all you need to know about roof extensions, their benefits, and some unique roof designs you can explore to make the most out of a roof extension. 

What are roof extensions?

This is the process of adding a new rafter to your existing one. What’s great about this home renovation project is you are creating new space without spending too much money. This is because you can extend a roof without the need to alter the structure of your home, so you don’t need to build a new wall or install support posts.

Types of roof extensions

Although most prefer their roof extensions to match their existing roof, no rule says your extension should be of the same style as your main roof. However, some roof types look better if their extension is of the same style. You can consult a roofing contractor, a building expert, or an architect to choose an extension that will match your needs and budget. Here are some popular designs you can consider:


Skillion is a single sharp roof incline you often see in porches or sheds. It is a budget-friendly option and easy to construct. This is an ideal option if you want to add a skylight or if you need additional storage in your attic. It is also ideal if you live in an area that experiences a lot of rain because it excels in allowing water to run off. 

Gable Roof

A gable is a triangular roof style you often see in classical house designs. This is an excellent choice if you want to create an internal space or if you want to add an attic. 

Flat roof

This is the simplest among extensions and is ideal for extending over any space without additional posts or pillars. 

Glazed roof

Instead of traditional roof materials, this type of extension uses a sheet of glazed glass. This is an excellent choice if you want to create a sunroom or if you want your extension flooded with natural light. 

Roof extension ideas

Attic room

Making use of your attic is one of the best ways to maximise extending your roof because it increases the usable space of your home. As your family grows, your needs also increase, and you can use your attic as an additional bedroom, a home office, or an additional storage area. 

Most attics have low headroom, and extending your roof can provide you with the needed headroom to have a functional bedroom. You can also use your attic as a home office if you transition into a work-from-home arrangement.

You can also make a fantastic family room out of your attic where you can watch movies with your family or spend time playing console games. What’s great about this idea is that you can make as much noise in your attic without bothering other family members on the ground floor.

Cover for patio/outdoor dining

Extending your roof can provide you with a sturdy cover for your patio. What’s great about this extension idea is there is no need to install new pillars or support posts. You can speak with your building designer, and they can help you plan for a patio cover that doesn’t require costly construction.

Extending your roof can also provide you with an outdoor dining area where you can enjoy meals with your family with a view of your garden or yard. This is also an excellent place to entertain guests or host intimate dinners. If you have enough budget, you can take this idea one step further and use the roof extension to build a kitchen extension so you can cook and serve your family while enjoying the fresh outdoor air.

Roof garden

If you have a concrete roof, it’s time to put it into use by building a roof garden via a roof extension. As mentioned earlier, a roof extension is an excellent way of getting an abundance of natural light to make an exceptional roof garden. You can use glass as a roofing material for this roof extension idea instead of traditional metal roofing materials. This is an excellent way to start an urban garden to plant vegetables or cultivate your favourite flowering plants.

A roof garden also makes an excellent tea room where you can entertain guests or have a quiet afternoon tea.

En suite Bathroom

If you’ve always dreamed about having a bathroom in your bedroom, then a roof extension might be what you need. With the help of a roof extension, you can increase the floor space of your bedroom for you to have an en suite bathroom. You can also do this in your attic room if you want a guest room with everything visitors need to be comfortable.

What’s great about this idea is customising your bathroom to make it luxurious. Instead of using a metal roof, you can opt for a glass or glazed roof so you can have a bathroom with a view. Install a tub under the glass roof, and you can lounge in your tub while gazing at the starlit sky for a relaxing and luxurious experience.

Private courtyard with pool

Roof extensions are also excellent for homeowners who want to have a private courtyard where they can entertain guests or relax after a tiring day at work. This type of extension typically utilises a flat roof extension like the ones for patios or porches.

If you want a one-of-a-kind private courtyard, you can also have your contractor build you a dipping pool that’s perfect for soothing your tired muscles. Line your courtyard with your favourite plants, and you can have a private oasis in the middle of the city.

What to look for in a roofing contractor

No matter how good your ideas are, your roofing extension project won’t take off without the help of a roofing contractor. An excellent roofing contractor can help ensure that your roofing extension project will proceed without delays and with excellent results while staying within budget. Here are some things you need to consider while looking for a roofing contractor:

  • Professional experience: Ask how many years they’ve been in the business. You can also check their credentials and licenses to ensure they passed required government trainings for professional roofers.
  • Proof of work: Request for pictures of previous roof extensions so you can assess the quality of their work
  • Customer feedback: If possible, ask for the contact information of previous clients so you can gauge how they treat clients and assess their work ethics.
