Wherever you go in the world you’ll see roofs. They can take on a variety of shapes and sizes to fit the needs of the people living in the conditions that they find themselves in. For example, the snow and wintry conditions of Scandinavia and the British Isles means that flat roofs are pretty impractical. Slanted and Triangular roofs are a much more common choice as it allows for the water and snow to slide off the roof into gutters or the ground. This reduces the amount of water and moisture that can get into the roof. The best way to protect the roof is to use a good Roof sealant like those from CT1.
Flat roofs are more common in warm climates. The amount of rainfall is greatly reduced and this means that the need to protect against dampness is greatly reduced. The countries of Morocco and Mexico for example all feature these designs over the slanted roof because there simply isn’t the need. It reduces the cost of the building, as it uses fewer materials, and also affords a cool space when the sun has gone down in the evening. It’s not unusual to see a family eating their evening meal on the roof by lantern and candlelight. In cramped cities, it can also provide a space for a garden.
Most slanted roofs use slate and tile to keep out the wet and let the rain slide effortlessly off without soaking in. However, in some areas, you can still see thatched roofs, a very traditional style, that are slightly domed.
