If you are planning a roof terrace, you should also consider the intended use: Is the terrace to be used as a place to relax or rather for parties and barbecues? If children live in the house, you should make sure that it is adequately secured by a railing. You can find out what else you need to consider when planning the construction of a roof terrace here.
Plan the location and size of the roof terrace
First of all, you should decide on the location and size of your future roof terraces. Should the terrace be placed on the roof of the garage? Does your house have a flat roof or another roof shape? How big do you want the roof terrace to be? When planning the roof terrace, make sure that the location is protected from view and wind. Too much noise, for example, from a busy street, also significantly reduces the feel-good factor. The terrace should also be placed so that there is as much sunlight as possible. In addition, however, you must always keep an eye on your budget – a very large terrace can quickly become surprisingly expensive. It is also important not to forget to install best snow guards if you have snowfall in the cold season. They will prevent snow from slipping.
Plan your roof terrace carefully – subsequent changes can be very expensive and costly!
Make sure that your neighbors do not feel disturbed by the construction of the terrace – this should be clarified early on to avoid disputes. Also, according to the building code, porches must be at least three meters away from the neighbor’s property. Once you have decided on the size and location, you can go into details such as planting. You can choose between potted plants and a green roof, for example in the form of a lawn.
The planning of the construction itself must be as accurate and precise as possible for the roof terrace. For this purpose, hire a roofer- he can clarify with you the process of construction and perform relevant tasks such as the calculation of statics to ensure that the roof terrace is safe and stable. This calculation as well as an overview of the planning, for example in the form of a sketch, are often required by the building authorities in order to issue the necessary building permit. In most federal states – excluding Bavaria and Hesse – this authority also requires that the terrace be built in cooperation with a civil engineer or an architect. As a rule, a building permit is always required, but there is no uniform regulation about this that applies to every federal state – so it is best to check with the relevant local authority.
The planning of the construction should also include a slope of the roof terrace: This ensures that rainwater can drain away, does not accumulate, and possibly flow into the adjacent rooms. Equally relevant is thermal insulation, through which as little heat as possible should be lost, especially during the cold season. With a poorly insulated terrace, the surrounding rooms remain cold in winter and heat up extremely in summer – this should be avoided by careful thermal insulation. This should be adapted to the building. Likewise, in any case, special emphasis should be placed on proper waterproofing: Roof terraces often result in the roof leaking due to sloppy work, damaging the fabric of the building or premises below. To counteract the wetness, professional roofers usually use bitumen membranes or liquid coatings.
Once the substructure is ready, you can finally plan the flooring of your future roof terrace – the most common materials are wood, natural stone, and tiles. When choosing tiles, you should make sure that the material is as weather-resistant as possible: rubber granules and ceramics are the most popular floor coverings in this respect. Wood is very sensitive to moisture, which is why it is suitable as an outdoor covering only to a limited extent: here you need to counteract the weather with regular maintenance and protective varnish. To keep your patio clean, a portable pressure washer can help. It does the job perfectly.
Plan the costs for the implementation of the roof terrace.
A roof terrace can be very expensive with planning and construction – so calculate as early as possible what your available budget is and what expenses are within the realm of possibility. This will help you keep track of your financial situation. This is where an experienced roofer can help you – they have experience in building roof terraces and can help you calculate the approximate cost of your desired terrace. Make sure that the professional also costs something – as well as the flooring, plantings and any decorations, because, with the construction of the terrace, the expenses are usually not finished – there follow costs for the furnishings in the form of furniture or plants, which are often disregarded during planning. In total, the construction of a roof terrace including planning can amount to several thousand euros – depending on the size and building conditions. The costs, including thermal insulation and waterproofing, can amount to up to €200 per square meter.
The decisive factor for the successful construction of a roof terrace is careful and early planning. The more detailed this takes place, the better your wishes can be implemented and the better the financial aspect can be planned. By hiring a competent roofer, you can additionally ensure that both planning and construction take place properly.
