Protection against Environmental Hazards
Shaped like a triangle, they are stable and far more effective when dealing with excessive weather, including heavy rain and snowfall. The roof design helps to direct the water away from the home and leaves little chance of waterlogging.
The natural ventilation underneath the top roof layer significantly improves the thermal efficiency of a building. This ensures optimal indoor comfort both in winter and summer.
The building envelope is responsible for around 25-35% loss of energy within a building. Pitched roofs are built to allow natural ventilation between the outer layer and the building, preserving energy.
Some roofing tiles have sustainable credentials to integrate solar panels within the structure of pitched roofs.
Flat roofs require constant maintenance of their drainage systems to avoid leaking. While pitched roofs are more expensive, cheaper and less frequent repairs compensates for this. This is especially true is the roof is covered in high-quality natural slate, with a lifespan of over 100 years and no need for any maintenance.
The pitched roof makes it easier to reuse rainwater than flat roofs. The external drainage system is easier to modify and maintain.
Pitched roofs can be converted to house substantial extra living space inside. This can be invaluable should extra room
