Roofing made by yourself

Do-it-yourselfers open up new fields of activity for themselves. So it is not surprising that well-versed self-makers meanwhile also approaches to roof structures and roofing. Nevertheless, you should go with great care to the roofing. Only if you have in-depth expertise can you, for example, cover a pitched roof of a residential building yourself. But you can also gradually approach ever larger work. Here are some valuable tips for making your own roofing.

Craft trades make a lot of sense

Not for nothing are there craft trades. With the ever-increasing requirements, for example, through the Energy Saving Ordinance (EnEV), the knowledge required to work on the house is getting more and more extensive. One such area is the roof. Not every roof should be self-made and covered. To do this, you must first differentiate between the possible buildings.

  • carports
  • garage roofs
  • terrace roofs
  • toolshed
  • garden shed
  • residential building

Roofing can not be done on each project

While roofing can in fact be done by most listed roofs, the residential roof is different. Roofing does not just consist of covering with roof tiles or other roofing materials. The thermal insulation of the roof is also part of the roofing.

The roofing already begins with the insulation

You can distinguish several possible roof insulations. All have in common that they must meet the minimum requirements of the EnEV.

  • rafter
  • Insulation between the rafters
  • Under rafter insulation (or rafter insulation from inside)

The different roof types

Clearly to be preferred is the Aufsparrendämmung from the outside. In this case, a thermal insulation and a vapor barrier or vapor barrier are attached. Whether vapor barrier or brake depends on the roof principle. Likewise the order of different separating layers, insulation, brakes, barriers and the roof skin.

  • warm roof
  • cold roof
  • inverted roof

Warm roof or cold roof - completely different constructions

Today's new standard is the warm roof, but until a few years ago it was the cold roof. The clearest difference results from the fact that a cold roof is open to diffusion from the inside to the outside, so that the moisture arising in the house can be dissipated via the roof ventilation.

The current construction standard: the warm roof

However, the warm roof is fitted with a vapor barrier so that the insulation can be made directly under the roof. The building moisture venting is otherwise ensured. Above all, it is important that no thermal bridges arise. Thermal bridges form condensation, which can not escape because of the vapor barrier. Mold, fungal spores and sponges are the result.

The insulation must be placed in competent hands

So if you really want to make sure that the roofing itself is to be made, you should at least arrange the insulation and the roof structure with a suitably certified company and have it carried out if necessary. You can leave the entire work to the operation until the insulation and then make the roofing itself.

Many weaknesses for design flaws not only in the do it yourself

Nevertheless, the most critical point remains the potential thermal bridges due to design errors. Again, there are particular vulnerabilities, where even good and experienced craft businesses can always make mistakes.

  • Closures to dormers and skylights
  • absolutely airtight seal with a vapor barrier
  • no thermal bridges at roof penetrations (fireplaces, antenna masts, roof hatches etc.)
  • Closures on verge, eaves and ridge

Requirements and laws

In addition, you may be required to comply with other legal requirements. Depending on your region, state, and individual project, you may be required to attach scaffolding, nets, and other backups. Any helpers must be insured accordingly.

Conclusion

Roofing on many smaller buildings and objects can be done by yourself. For residential buildings, you need in-depth knowledge of legal requirements and energy laws, the construction of insulation by roof type - and you must ensure error-free work on penetrations and closures explicitly.

Tips & Tricks

If the requirements are too high, but you prefer the roof covering yourself, there may be another alternative: Get an expert on the side, who accompanies your roofing, checks everything for correct execution and if necessary reveals errors and design negligence.

The roofing of numerous smaller buildings and roofing can also be done by yourself. In the house journal, we offer you a wealth of different articles, such as roofing with bitumen shingles.
