What are the steps for roofing construction?
The roof is a construction that requires professionalism and proper technique. Gikas Roofing Roofers share with us the mistakes that are followed in the construction of a roof.
Until sometime, the roofing construction – wooden roof was done as follows:
The skeleton was placed and the skin on the skeleton. Then all the technicians and roofing contractors used slats nailed on the rafters of the frame, so that in the next step the waterproofing membrane (asphalt cloth, in the old years) was spread to protect the construction from water ingress.
Above this membrane and then specific logs are nailed, at some intervals, so that the roof tiles can be placed on these logs. At the same time between the logs you use insulation (insulation we, Gikas Roofing Roofers mean some sheets, panels in different thicknesses depending on the thermal insulation requirements of the building and the roof). This process is done and followed by all companies manufacturing wooden roofs and tiled roofs, obvious and not all years.
Studying and thinking this way and applying it to constructions all these years, I realized based on my experiences many flaws in this process for the owner, but also for the manufacturer and therefore for the construction itself.
But let’s start from the beginning of a roof construction
By placing the waterproofing membrane on our roof we try to protect the construction from any water inflows by creating a single layer of protection above the construction. However, by nailing the rods to support the tiles, we open so many wounds in the membrane from below with the pins or screws that we will use to support them, which is unacceptable. Imagine that for 100 square meters we use at least 100 bolts or screws to support the frames, hurting 100 times our waterproofing.
It is certain and time has shown that water is unpredictable and penetrates from everywhere, even from the smallest hole wherever it finds escape. These nails and screws rust with the years and the rains, therefore they rot the logs and then the basic woods of construction. Even when the damage is not visible from the bottom of the structure it is certain that there is an intrusion problem internally.
Between these logs is necessarily placed thermal insulation cut to cover the gaps between them on the entire surface of the roof. Another tragic mistake, how can we have proper thermal insulation, since there is thermal break from the logs if there are regular intervals of the roof. It is like using double glazing in a house window but not putting rubber bands in between. Huge losses are created and in fact we do not achieve the desired result.
All of the above are basic and extremely important problems if you want to achieve an excellent waterproof, but also thermally insulated wooden roof or tiled roof.
Thinking about all these problems and having faced them over the years in many roofing constructions in New Jersey, competitors and acquaintances I thought of a revolutionary new way of making wooden roofs and tiled roofs to solve all the above problems and in addition I reduced the construction time a lot, helping and the manufacturer throughout the process.
I thought and applied the following way, now above the waterproofing membrane the placement of the logs is removed and the thermal insulation is placed in any thickness required by the design study, which, at the same time, has small gutters drawn on its surface, so that in them the movements to anchor the “legs” of the tiles during installation. The sheets of thermal insulation knit together during installation and thus create an outer single shell above the roof.
This does not hurt the waterproof membrane or anything else used from below for waterproofing, because there are no more logs with nails or screws nailed to its entire surface. This shell that is formed helps the house to be 100% thermally insulated and without losses.
In this way of constructing a roof, our work in New Jersey becomes 100% more efficient due to non-piercing of the membrane, but also because our thermal insulation is without thermal break. At the same time, the artisan manufacturer who installs this material in this way saves a very significant time from the construction, as well as it is more relaxing as the installation of logs as is done so far except harmful for the roofing construction is a laborious and time consuming process. This idea of insulation parallel to the surface of the cynics for the anchoring of the tiles as if we were using rods, is in all respects more correct but also now necessary for us, Gikas Roofing Roofers to be able to say that it has achieved an excellent result and structural perfection.
