Roof: types and recommendations

How many roof types exist?

Which is the most recommended roof type?


In this post we explain the types of covers that exist.
In case you still do not know us, let us introduce ourselves.
We are ERA architects, one of the young, committed and creative architecture studios in Barcelona.
In this post you can find our professional and simple explanation of covers.


What is a roof?
It is the top element of the building.


What are the types of roof?
We are able to classify the types of roof according to:

Simple or Composite

Flat or inclined (1 slope, 2 waters, 4 waters, broken or folded)

Passable or not passable

Traditional or Inverted

Natural Vegetables (straw, wood, cane, plants) or Minerals (gravel, earth, abode)
Artificial (slate tiles, ceramics, cement, metal panels, glass, rubber or plastic)


What is the most recommendable roof type?

It depends on location, climate and also on the program of the building and its integrated insertion in the environment.

Even so, in ERA architects we recommend the inverted flat roof (passable or not) combining areas of low maintenance plant cover with autochthonous plants pre-cultivated respecting the environment and nature.

I imagine this will sound very complex for that reason we are going to develop this description more:

Flat roof is the roof that with a minimum of inclination between 2-8% is able to stay waterproof and repel water from rain.
Inverted cover is the cover in which the thermal insulation protects the waterproofing sheet. This is possible to an innovation with respect to the traditional and that makes the waterproof sheet is protected and the cover is a little ventilated. Therefore the condensations are eliminated, the dilatations, cracks and aggressions of the impermeable sheet are diminished. It is also better protected and its maintenance is more comfortable.
Trafficable cover is a generally flat and accessible cover for for example making a barbecue with friends. The difference is in calculating the structural loads that the roof must support while choosing comfortable materials for walking.
Vegetal cover is a landscaped cover with plant elements. There are many types of cover systems at the same time as plants to choose from.


In our architecture studio ERA architects, our main objective is the total success of the project and the work. For this reason we recommend our clients inverted flat roofs.

If you choose to make a house with an inverted flat roof, we recommend that you also consider that it has a vegetal finish.

In the next publication, we will explain the plant cover systems.

Read you next week!
