No part of a house is so much exposed to wind and weather as the roof. Yet owners frequently underestimate the need for refurbishing it completely, although a thoroughly planned modernisation offers many advantages and the cost of refurbishment may be recovered within only a few years. For if you refurbish a roof efficiently, keeping an eye on the optimisation of your insulation, you will lower your heating and energy costs and possibly receive subsidies for your energy refurbishment. Once the roof is back in good condition, the value of the house will go up because the roof has by now become an important indicator for the condition of a property. So there are many reasons why your roof should be kept in good condition and possibly refurbished completely.
Luckily, refurbishing a roof is not frequently necessary. However, there are signs indicating that an old roof should be renewed or renovated. If, for instance, damage is increasingly frequently caused by broken or missing tiles, steps should be taken to prevent damage to the layers underneath. Often, moisture is an unmistakable sign indicating that a refurbishment is necessary.
Needless to say, refurbishing a roof may also make sense if there is no immediate damage. There are many cases, for example, when a building could do with improving its energy budget by complementing and/or renewing its heat insulation in order to reduce its consumption of energy. The amounts saved in heating costs might pay back the cost of refurbishment after a comparatively short period of time. Therefore, refurbishing a roof will pay off if its covering is outdated or if energy-saving measures make sense.
Those who refurbish a roof these days generally attach great importance to an agreeable and healthy interior climate, modern living comfort, and low energy consumption for heating. If aspects of environmental and climate protection are to be considered as well, refurbishment is probably the only solution that complies with the current energy saving regulation (EnEV) or even stricter requirements.
Energetic roof renovation may turn out to be difficult in older buildings. For one thing, their roofs are highly structured, featuring dormers, ridges, and valleys that make them difficult to refurbish. Where listed buildings are concerned, refurbishments that are necessary for energy-efficient living often cannot be reconciled with the regulations imposed for the protection of such buildings. However, given the right products, detailed consultation, and proper funding programmes, roof refurbishment may be made to pay even in old buildings to lower their energy consumption and ensure an agreeable living climate.
There are a number of funding programmes for roof refurbishment for which applications may be submitted to banks, city councils, or government institutions. To receive funding for your refurbishment project, you should remember to submit your application at all events before work begins to avoid losing your entitlement to a subsidy.
Depending on the nature of the application, owners may be supported either by a low-interest loan or a direct investment subsidy. Although there are certain standard rates, the amount to be paid in support will always be computed individually. A particularly popular programme for funding energy-efficient roof refurbishments is offered by the KfW (Kreditanstalt für Wiederaufbau) . However, Land and municipal governments also operate their own funding programmes. A building energy consultant will inform you about the conditions applying to your specific project. In the following, we will show you what DELTA® roof systems can help you comply with the EnEV or obtain funding from the KfW.
To decide which system solution is right for you, you had best consult your building energy consultant or a roof expert. Further information on subjects relating to roof refurbishment and to funding, consult our current roof guide for owners.
More and more people decide to stop using the room under the roof only for storing odds and ends and create additional residential space instead – and for good reason, too: Converting a pitched roof and possibly refurbishing it at the same time is advantageous to the user in many ways. You will benefit not only from extra space for living but also from the improved energy efficiency of your house.
Owners who decide to convert an older attic should renew the insulation at the same time. A modern insulation will protect the attic from cold in winter and from overheating in summer. To profit fully from the protection of an energetic modernisation, the heat insulation must be expertly installed.
By the way: for the heat insulation to retain its function fully, a vapour barrier should be installed which keeps airborne moisture from the interior from penetrating into the heat insulation and damaging it. Dörken offers you a large selection of draught and vapour barriers for any construction issue.
DELTA offers numerous system solutions for retrofitting heat insulations either as roof-deck insulations or as a combination of roof-deck and between-rafters insulation, always tailored precisely to the individual requirements and needs of the owner. The advantage of these system solutions is that refurbishment work may be carried out from outside without interfering with the living space inside.
For new buildings, the Energy Conservation Regulation (EnEV) legally prescribes heat insulation. With the DELTA systems you will be on the safe side because they reliably insulate your house and even offer you an opportunity to increase your heat protection considerably beyond what is required in law. Sound insulation and top-quality draught and vapour barriers permit long-term savings in energy costs.
