Roof Anatomy: The Vital Parts of Your Roofing System

While most homeowners know how important the roof is in terms of aesthetics and security, few actually know what makes the roof what it is. Most homeowners see the roofing system as just one structure, unaware that there are different parts that play a key role in safeguarding your home against the elements.

Signature Exteriors discusses each vital part of your home’s roofing system. It’s important to be aware what these are so you know exactly what to address when your roof experiences a problem.

Roof Decking

This part of the roof is the foundation which every other component is laid and installed on. As the literal foundation of your roof, it’s what most people call the “roof structure.” The material for the roof decking varies, but the most common are strand board and plywood.

In some homes, especially contemporary and ultra-modern homes, the roof decking is made from other materials, such as concrete and polystyrene. Metal is rarely used, but it’s a solid choice, as well.

Flashings

These are the thin metal strips that protect the most vulnerable parts of the roofing system from water damage. You’ll most likely see them on the slope and joints, as well as the base of the chimney. While their main role is to prevent water intrusion, they are susceptible to water damage as well.

If your roof is experiencing a leak even though you know the roof wasn’t damaged or has any holes, it’s most likely due to damaged or torn-off flashing. Timely flashing replacement can keep you from spending money on a pricier repair project, so keep this in mind.

The Underlayment

This is the underside of the roofing shingles and is the roof’s last line of defense against leaks. This is made of a durable paper that’s moisture resistant. When it’s time to replace your entire roof, you’ll have to replace the underlayment, too. A new set of shingles needs a new underlayment.

Shingles

Shingles can be made from a range of different materials and are the most visible part of the roof. On top of protecting your home from the weather, the shingle layer also plays a key role in establishing the curb appeal of your property.
