The roof renovation is part of the Gethsemane Church Renovation project. Here are presented several findings and measures applied in relation to the project. The resulting timber is used for other internal structures as a cradle to cradle strategy
Most of the timber is dry, cracked and it has a low degree of insect infestation(termites/house longhorn beetle). At the eave level, the timber presents traces of moisture and deterioration. The soleplate and the eave region are in a bad condition. The steel bars(supports) are rusted.
The roof is removed and replaced with a new structure. The materials are replaced with more efficient structures and materials. The timber is replaced with new, fireproofed materials according to regulations.
The tiles and slates are in good condition excepting the mortar around the tiles which in some places has holes.
They are reused for the new roof structure.
The insulation is soft wool. At the sides of the roof, a membrane is used to keep the insulation in place. The insulation quality is too low.
Insulation is replaced with much higher quality materials in a bigger quantity to fulfill the energy demand.
The roof windows are mounted in the roof tiles. They are covered in rust.
New windows with better energy features are required.
No sharking felt is found. No roof anchoring is noticed
Is replaced in the new roof structure. The roof anchoring is done according to wind structural calculation.
