Installation of a round chimney will require additional costs, since its proper organization requires additional components.

Bypass of the rafter system
A high-quality connection of the roof to the chimney pipe is possible with the presence of rigid sheathing, which allows for an even distribution of the load. The chimney is usually installed before the rafter system is strengthened.

If the output is carried out later, it is important to provide a distance from the rafters of more than 20 cm, otherwise it will be necessary to dismantle the lathing, weakening the overall system.

Chimney lathing

Install support posts under the rafter frame elements, cut off the overlaps and connect them to the whole rafters using horizontal crossbars.
Around the flue pipe, build a reliable frame that is firmly connected to the rafter system and roof sheathing.
Chimney passage through a metal roof
Waterproofing a chimney on a roof made of metal tiles requires the preparation of the following tools and materials:

construction pencil or marker;
drill and drill bit set;
grinder with 2 mm disc;
silicone sealant;
riveter;
aluminum tapes and clamps;
metal corners;
roofing screws;
long ruler or tape measure;
pliers and a hammer.

Bypassing a chimney on a roof made of metal uganda mobile database involves creating two protective layers, which are made as follows:

An internal apron is assembled on the lathing, covering the roof and chimney.
Prepare the outer decorative strips covering the roofing material and the lower apron.
If the smoke system is located near the ridge, then the edge of the top bar is inserted under the ridge element.

The installation of the internal apron begins with the bottom wall of the riser.

Each element covers the slope by 200 mm and rises vertically along the ventilation structure to a height of 150 mm.
The side strips go under the ridge of the metal tile, cover the lower element of the apron along the entire length, and extend beyond the pipe by 20 cm.
All parts are firmly connected with self-tapping screws.
Measure 15 cm on the pipe and make a 15 mm deep groove with a grinder.
Next, fill the ditch with silicone sealant, after which fix the lower abutment bar.
When pouring silicone, you should not spare it, it should fill all the voids between the pipe and the apron

Important! The top part of the apron must fit tightly into the groove filled with sealant.
