PROJECTS REALISED WITH OUR PARTNERS



Selected projects of COMAX® ROOFS realised with our partners in the past season 2018. Also, this year, in this section we will focus on pitched roofs refurbishment and pitfalls associated with their ventilation and the quality of craftsmanship.






Here you can see selection of our realisations. We will add more and more in the future. 




SHEET METAL ROOFING COMAX TILE WITH STEEL CORE


The single-skin roof with its rugged surface hid many pitfalls and put the emphasis on the craftsmanship of the tinsmithing and carpenter firm SEKEL. The aluminium roofing Alukryt ® , which has been replaced by a sheet metal roofing COMAX TILE 350 with steel core, already exhibited leaks and malfunctions. 

The main problem with the reconstruction of the roofing was the refurbishment of the old roof truss, which showed signs of damage by the by the wood-destroying pest and the deflection of the rafters in the main part of the roof gable towards the street to the walkway by up to 130 mm. For safety of pedestrians on adjacent roads, it was necessary to design a double-tubular snow trap, to secure the roof in case of a roof avalanche.

COMAX KLIK WITH STANDING SEAM IMITATION, FOR EASY CLICK OF THE SHEET LOCKS


Reconstruction of the office building of the former Wood Works in Velvary, which took place in 2016. On the simple gabled roof with low pitch, the main waterproofing layer was damaged, it was missing in several wind-stressed places. The building suffered from an improperly chosen type of roofing that did not match the existing pitch of the roof. 

The safe pitch for the Alukryt metal sheet was not followed by a full 19°. Overlapping of individual roofing templates for safe connection based on the pitch of roof surfaces and insufficient anchoring of the roofing in the area was also found to be unsatisfactory. As a suitable solution for the reconstruction of the roofing, the metal roofing COMAX KLIK WITH STEEL CORE was chosen that meets the requirements for pitch of roof from 9 °, and is also suitable for installation on classic battens 40 x 60 mm with a span of 250 mm. 

DOUBLE STANDING SEAM - COMAX FALC, METAL SHEETS INTENDED FOR SEAMING  


The first stage of the reconstruction of the roofing of a family house in the village of Chržín near Velvary took place in 2016. This year we would like to complete the second stage of the reconstruction of the gable part of the roof with the supply of coated aluminium sheet intended for seaming with all additional assortment.

The original asphalt roofing for pitched roofs already showed signs of damage and leaked into the residential roof area of the house. The fitting company failed to lay the original roofing on the all-over deck and did not provide enough ventilation gap to vent the roof structure. This caused fraying, cracking and subsequent peeling of asphalt roofing, which resulted in the loss of its main waterproofing function. After the renovation of the interior without the possibility of changing the roof structure, the gable roof with many roof windows made it impossible to use the sheet metal roofing, which the customer originally chose for the simplicity of its installation on classic battening. The fixed layout of the roof windows and the age of the roof truss predetermined the use of the lightweight Comax Falc aluminium roofing, which was applied to the original all-over deck and adjusted to the roof structure and the current condition of the roof truss. We are looking forward to further cooperation.
