Whether you need a new roof or want to repair an existing one, you’ll need to understand how a roof is constructed to understand the offer you’ll receive from your roofing company.
A roof is much more than the visible part. A roof is a complete system of structures and layers that will protect your property. Knowing the anatomy of a roof will help you understand the importance of roof repairs and upgrades. Maintaining your roof in optimal condition will prevent water damage from weakening your house and creating structural problems.

A roof can last 20 to 50+ years, depending on the materials used in its construction. Be sure to invest in quality materials and hire an experienced roofing company near you that will guarantee excellent workmanship.
What are the 3 main components of a roof?
A roof has a basic structure, a frame that gives it shape. This is made of beams called joists, trusses, and rafters. This frame will support the other components of the roof.
The sheathing, or roof decking, is a layer of flat wooden boards – usually plywood or planks – or oriented strand board (OSB). On this flat structure, the other roofing materials will be installed. You will need to replace your sheathing if it is rotten.
The next layer is the underlayment. This material is like a membrane that gives extra protection against water. It’s installed between the shingles and sheathing. It is usually made with felt. Nowadays, synthetic materials are being used more and some will even protect against ice.
Over this structure, you will find the covering. This is the visible part of the roof. It can be made of different materials such as metal, slate, steel, or asphalt shingles.
What are the common parts of a roof?
Other common parts of the roof are shingles, ridge capping, roof vents, roof flashing, and the attic.
Shingles are small overlapping or interlocking tiles that are used as the cover of the roof. They can last 25 to 50+ years.
The ridge capping is triangular bent material installed where two surfaces meet, above valleys and hips on a roof. Easier to spot at the top of the roof, this ridge capping covers the gap that, if not properly covered, could be prone to water leaks.
The roof vents ventilate the attic and prevent heat and moisture from damaging a roof. The airflow lets hot air escape and helps to extend the lifespan of a roof. The attic is the space between the roof and ceiling.
The roof flashing is a thin metal material that directs water away from joints and seams, and toward gutters instead. Roof flashing seals the roof and prevents leaks. They can be made of plastic, aluminum, or steel, most typically. They can last up to 30 years.
