When applying the waterproofing membrane on the thermal insulation, make the connection between the plane and vertical parts with prefabricated triangular elements.
All vertical parts should be treated with a coat of VERPRIM bituminous primer.
The waterproof coat of the flat part will be turned up and flamed for about 10 cm on the vertical part.
A second sheet will be flashed over the previous layer from 20 cm on the flat side and turned up vertically to the head of the parapet, and then protected by a metal flashing mechanically attached to the parapet.
In the case of vertical walls with low height, protect the waterproofing layer to finish on the vertical by means of a metal flashing, mechanically fixed and sealed with silicon mastic.
All corners and edges to be covered by waterproofing membranes shall be rounded by cement mortar fittings or by using prefabricated profiles.

Cut out in the supporting structure (or in the insulation, in the case of insulated roofing) a seat slightly wider than the crown of the vent and about 1 cm deep.
The drain hole should be sized according to the area of roofing involved, considering a maximum drain flow rate of 3 liters perm2, as shown in the following table:
The drain outlet shall have a connecting crown at least 10 cm wide from the edge of the drain hole. Treat the downspout seat with VERPRIM bituminous primer. Cut a piece of membrane and flare it on the seat. Cross-cut the membrane at the hole and insert the nozzle. Glue the crown of the nozzle by flaming the piece of membrane underneath. Then flame-apply the waterproofing membrane, turning it up and welding it to the inside of the nozzle tube. Attach a bezel or leaf guard to the hole.

The waterproof membrane will be applied by starting the laying approx. 20 cm from the wooden element.
The membrane will be turned up over the wooden element, on the vertical side, up to an elevation approx. 10 cm below that of the vapor barrier (see drawing).
The second layer of waterproofing should be applied by stopping at the edge of the roof.
The outer edge of the roof shall be protected by metal flashing.
Treat the surface to be waterproofed with VERPRIM bituminous primer.
Then flame-apply the vapor barrier in full adhesion to the substrate, continuing to the edge of the supporting structure.
At the perimeter of the roof, apply a rectangular-section wooden batten having the same thickness as the insulation used, mechanically fastening it to the supporting structure. Afterwards, lay the thermal insulation.
Attach a second wooden element with trapezoidal cross-section to the first lath (see figure).
The waterproof membrane will be applied by starting the laying approx. 20 cm from the wooden element. The membrane will be turned up over the wooden element, on the vertical side, to an elevation approx. 10 cm below that of the vapor barrier (see drawing).
The second layer of waterproofing should be applied by stopping at the edge of the roof.
The outer edge of the roof shall be protected by metal flashing.
Provide a threshold height such that the waterproofing membrane can be turned up on it vertically at least 10 cm above the maximum water level.
Provide around the spilled elements crowning walls 10 cm higher than the floor level. The waterproof membrane may be turned up vertically on the wall and on part of the outflowing element.
It will be protected by a metal drip pan, mechanically attached to the element and properly sealed with siliconized mastic.
If possible, in the case of chimneys, a vertical seat for waterproofing can be made as shown in the figure.
An expansion joint inserted under the floor should have a seat about 2 cm deep and 5 cm wide.
The gap should be widened in such a way that the waterproofing membrane inserted in the joint can be conformed to an inverted omega, with a development such that it is not in tension at the maximum opening of the joint.
Insert a strip of elastomeric membrane straddling the joint so that it forms an omega in the gap, fixing it in full adhesion on the substrate at the side edges of the sheet.
Then flame-apply the waterproofing membrane up to the edges of the joint. Insert a bead of compressible material inside the omega so that the joint gap is completely filled.
Next, flare another strip of elastomeric membrane across the joint.
Arrange around the joint crowning walls with a height equal to that of the thermal insulation. Apply the vapor barrier by turning it up on the walls up to 5 cm from the edges of the crack.

Turn the vapor barrier back to the vertical of the flange and flame weld it.
Lay the thermal insulation.
Insert the second aerator element onto the first, as shown in the figure. Apply the finishing waterproofing coat, taking care to turn it upside down and flame weld it to the vertical of the aerator.
Treat the surface to be waterproofed with VERPRIM bituminous primer.
Flame-apply the vapor barrier, allowing it to penetrate up to about halfway up the eaves channel.
Next, flare a piece of membrane over the gutter area, causing it to rise a few cm beyond the edge of the gutter.
Apply a wooden batten at the head of the eaves as shown in the figure, then lay down the thermal insulation by placing the first row of panels next to the batten.
Before laying the waterproofing membrane, flare another piece of membrane on the eaves gutter area, as explained above. Afterwards, flame-apply the finishing seal layer on the horizontal part, making it go down to about half of the eaves channel.
The outer edge of the eaves shall be protected by metal flashing.
Given the different thermal expansion coefficients of the constituent materials of the system, in this case it is advisable to make the connection with the waterproofing membrane using the “pontage” technique.
It involves fixing a piece of elastomeric membrane on the joint between the structure and the channel, so as to compensate for the mutual movements of the two materials.
The waterproofing membrane will be turned up inside the eaves channel and flame welded in full adhesion.
