Roof design basics
Now that you know the different parts of a roof structure, let’s talk about roof design. The design of a roof affects its appearance, functionality, and durability.
Flat roofs give off a modern vibe, but they require more care in terms of draining rainwater and cleaning. Other roof profiles, like standing seam roofs, also safeguard your home against water leakage.
Single-pitch roofs are economical. They are usually found in sheds and storage buildings. They traditionally do not provide a lot of insulation and ventilation, but there are now technologies that help keep your home breezy. With Metalink, standing seam and snap-lock roofs can be applied with insulation, such as expanded polystyrene (EPS).
Gabled roofs form a triangular shape and are a popular choice. Besides their aesthetic appeal, they are effective in shedding water, promoting ventilation, and offering additional attic space and natural lighting options.
Vaulted roofs have an elegant arched shape. But due to the complexity and expense of building vaulted roofs, these are usually only used in churches or historical buildings.
Kinds of roof coverings
Aside from the shape of the roof, you can also choose the design and texture of your roof by selecting from a wide variety of coverings.
Rib roofs lend an ultramodern design to buildings because of their symmetrical lines. Metal rib roofs with a stone finish are durable as well as beautiful.
Tile roofs are a classic choice but can also be made to look modern, depending on the finish. Contemporary tile roofs are available in stone-coated finishes that are highly durable, and in elegant textured gray finishes such as Metalink’s TEKTURA Series. Tile roofs are also available pre-painted in a wide variety of bright colors.
Horizontal roofs exude a stylish Japanese vibe, so if you want your building to stand out, consider installing a horizontal roof.
Curved roofs are strikingly beautiful. They are usually used in airports, arenas, universities, and stadiums.
You can also choose bended accessories to use on your roof. These gutters and flashing direct and drain water, increasing the roof’s durability. You can get bended accessories in a wide variety of paint finishes to suit your personal aesthetic.
Why you need a complete roof structure with compatible materials
The type of roof you choose ultimately affects how your roof performs against moisture seepage or build up, indoor air quality, and the building’s energy efficiency. Likewise, your roof structure and roof materials affect the roof’s structural and aesthetic integrity. So start with good design and use quality materials to help you avoid problems and save money in the long run.
