Your roof is more than just a single structure, although it’s easier to think of it as just one piece. It is actually not a roof but a roofing system that’s made up of many different components that when totaled together make up a protective barrier for our home. If you have been considering a new roof or replacement roof, it can’t hurt to familiarize yourself with the five components of a shingle roof system so that you can understand how they work in unison for the benefit of your home.
The base layer of your roofing system is its decking. This is generally made up of plywood or possibly composite sheeting. The decking is nailed to the rafters of the roof. Your roofer will make sure that the decking is of the right thickness for Florida’s specifications and codes. This is important because it forms a structural barrier to protect your home from storms, including the hail that sometimes accompanies them and from any falling debris, like limbs. In roofs that lack maintenance for a period of time, the decking is the first thing to “go,” a circumstance that will add to the cost of any roof replacement.
On top of the roof’s decking is the underlayment. This keeps the decking dry. This is vital for avoiding wood rot or leaks. Wax or tar paper is generally used to make underlayment. This is your roof’s initial waterproofing.
The job of your roof’s flashing is to reinforce the roof system at its key features and transitions. Usually, metal flashing is applied at the roof-to-wall transitions, roof edges, and valleys, and around skylights, dormers, and chimneys, among other markers.
What you actually see when you look at your roof is its shingles—they are what makes the roof attractive and gives your home a finished look. Shingles can be made from various materials, all of which are selected for their abilities to protect the roof’s decking and underlayment from varying levels of sun, wind, and rain. Shingles overlap one another, so rain and debris roll away without making their way down to the bottom components of the roof. Most roofs have a row of so-called starter shingles around the roof’s top edge. Traditional shingles are positioned in the field. Specialty shingles, including ridge cap and hip shingles, are installed on hips and ridges.
Last but not least, the fifth component of your roofing system is its ventilation. A properly installed roof needs a roof of vents installed along its ridge. This allows moisture and heat to escape from your attic. In Florida, proper ventilation is super important for saving on the cost of cooling your home. If your roof is not properly ventilated, then heat will stay in the attic, raising the temperature inside your home and making your HVAC work harder to cool your interior.
