Planning a Roof Loft Conversion
Gambrel
A gambrel roof is a popular choice for a loft conversion. This type of roof has two slopes on either side, punctuated by dormer windows on the lower slope. This design allows more habitable space and saves money on building materials. It is also relatively easy to frame.
Gambrel roof conversions can be tricky to carry out as they require changes to the front design of the roof. However, they are a popular option for people who want to increase the headroom in their upper floor. These roofs are similar to mansard roofs in that they have two slopes — one shallow and the other steep. This style of roof allows for the maximum amount of headroom in the loft space.
A gambrel roof conversion may not be possible if the current ceiling joists do not support the new floor. If so, you may have to hire a structural engineer to decide whether this option is viable. This structural engineer will assess the separation distance between joists and specify the correct joist size and grade. During the loft conversion, new joists will run alongside the existing joists and span the gap between load-bearing walls. The new joists will be raised to avoid touching ceiling plaster. This will require the use of thicker timbers to bridge the gap. This may also require the use of rolled steel joists to spread the load more evenly.
Mansard
If you want to convert a mansard roof into a loft space, there are a few steps you need to follow. First, you need to hire an architect to design the plan. This architect will also work with a structural engineer to help with the structural calculations. Then, you must submit the plans to your local planning department. Your architect will guide you through the entire process. This is a complex project, and requires expertise and constant input.
Generally, mansard roof loft conversions are best suited for properties that are located in densely populated areas. These conversions will add a whole storey to your home, adding usable living space. It is important to measure the headspace before you start work, as you will need a minimum of 2.2 metres of headspace. This is measured by running a tape measure from the floor to the highest part of the ceiling.
Hip-to-gable
There are many factors to consider when planning your hip-to-gable roof loft conversion. First, you’ll need to work out whether you have permission to convert your loft. Many houses are built with certain restrictions on development, and some require the consent of other owners before any construction work can begin. In addition, you’ll need to make sure you have enough headroom and space below the floor for a staircase. You’ll also need a qualified structural engineer to ensure that the work meets building regulations.
Hip-to-gable roof loft conversions can be a great way to create an extra room in your home. They can add a new loft bedroom, a new guest bedroom, an office, and more. A hip-to-gable roof conversion can increase the value of your property and increase its overall square footage.
Trussed rafters
Trussed rafters are a relatively inexpensive way to convert an existing roof into a loft space. They are made of slender timbers with a characteristic W-shaped webbing. They are commonly used on roofs built from the 1960s onwards.
A trussed rafter roof is built from W-shaped rafters to support the entire loft floor structure. These types of rafter roofs were typically installed as a cheap option when a house was first built. However, it can be difficult to convert an attic with this type of roof. Also, you may need planning permission if you want to raise the height of the truss roof.
When installing trusses, it’s important to remember that they need a space between them. In addition, breathable felt roofs need a void above them to prevent condensation. The new roof structure must be securely in place before trusses can be installed.
Shell conversions
If you’d like to add an extra floor to your home and want the added benefit of a watertight structure, shell conversions for roof loft conversions are an excellent choice. The structural work is done by a building firm, leaving you to take care of all the finishing details. These include plumbing, plastering, electrical installations and 2nd fix carpentry.
Many loft conversion companies will offer a free quote for your loft conversion project. However, you should make sure that you’re getting an itemised quote. This way, you can subtract the cost of labor from the total cost.
