The aim of lectures are systems of flat, pitched and steep roofs. The course also provides an understanding of special systems of thermal insulations based on thermal radiation reflectivity and modern and unusual types of assembled roofing including solar roofing. The next part of the course will be aimed at modern waterproofing layers and thermal insulations and their connection to various types of roofs. The great attention is paid to construction details.

Learning outcomes

Students will be acquainted with solutions of compositions of roofs. During the exercise resolves and details of tracks and completion roofs, rainwater roof drainage, including with the possibility of practical demonstrations of segments and modes of implementation. This knowledge can used of in designing of buildings at teaching in the atelier.


Thermal-moisture processes in building envelopes, basic classification of roofs according to a pitch, shape, structure, serviceability, requirements etc. Outer and inner boundary conditions for roof designs above heated and unheated spaces. Drawing of roofs according to the valid standards.


Basic knowledge of roofing construction and engineering buildings thermal and acoustic properties of building materials in the building envelope construction.

Planned educational activities and teaching methods

In the lectures provides examples of typical construction details of buildings and at excercise are applied to the specific cases of use.

Forms and criteria of assessment

Elaboration of work at the regular and continuous consultation in the exercise. Obtaining of credit is a condition for the exam. The exam consists of a written and oral part.


A design of the exact, clear and particular flat or pitched roof above various thermal and moisture internal environment. Knowledge of the detailed design and material design of terraces, roof parking lots, heliports and green roofs. The issue of details. A basic overview of the structural and building physics principles for reconstructions of single and double leaf flat roofs.
