    Emily Videtto: Hi! I am Emily Videtto, Executive Director of Residential Roofing at GAF. Today, I'm going to explain the components of a complete roofing system. A roofing system is a highly advanced system of components that work together and do much more than just keep the water out. A properly design roofing system keeps your attic cool or dry and its make your home a more comfortable place to be. So, what are components of a well designed roofing system? It starts with a high-performance leak area to protect the most vulnerable areas of your roof like at the eves, in valleys, around chimneys, and plumbing vents, these areas are notorious for leaks.

    Today's leak barriers are made from a rubberize compound that creates a water proof protective barrier.

    Next, you have the roof deck protection, this helps prevent wind driven rain that could get under your shingles from getting inside your home. Traditionally, roof felt has been used for roof deck protection, but today there are high-performance products that will provide long-term protection, long after inexpensive felts can become brittle and disintegrate. After that is the Metal Drip Edge, this is a component that helps keep water away from the roof's edges and provides a clean finished look to your new roof.

    Next is the installation of specially designed starter strips at the eves of your roof. Starter strip have a factor applied adhesive that will tightly lock the first row of your shingles in place and help prevent blow offs. Now it's time to install the shingle. At the at the top of your roof your contractor may recommend installing a ridge vent which along with corresponding soffit vents in your eves or intake vents allows hot moist damaging air to escape from your attic. The final component is ridge cap shingle to give a nice finish look to your roof and match the performance of your roof shingles.

    You will want to make sure that your contractor installs all of the components of a complete roofing system and doesn't skip any to cut cost because that can mean trouble for you down the road. When it's all done you will have a beautiful new roof that not only looks great, but also keeps the whether out, increases the comfort of your home and will last for many years.
