Sheathing (or decking) is the part of the roof to which your roofing system is attached. Sheathing is typically made of plywood, OSB, 1" plank, 26 guage metal, or concrete. (see Figure 1)
Eaves are the part of the perimeter of your roof. They are oriented parallel to the ground. (see Figure 1)
Gables are the part of the perimeter of your roof. They are oriented from your eaves toward the peak of your roof. (see Figure 1)
Valleys are the intersection of 2 roof facets. Rain water typically collects at larger quantities in these sections. (see Figure 1)
Ridges are located on the peaks of your roof where 2 roof facets meet. (see Figure 1)
Hips are located where the sides of 2 roof facets meet. (see Figure 1)
Fascias are located below the roof edge. They are either covered with metal or plastic cover or painted. (see Figure 1)
A square is a unit of measurement used to represent 100 square feet.
Pitch or slope is a measure of the steepness of a roof. It is measured in the rise over a 12 inch run. The typical roof slope in Central Florida is 6:12.
Pipe flashings or boots are roof flashings used to cover sewer exhaust pipes. (See Figure 2)
Exhaust flashings are roof flashings that are used to cover bathroom and kitchen extractor exhaust ducts. (See Figure 2)
Drip edge flashings are an integral part of your roofing systems that help divert water from running down your fascia. Florida Building Code requires that new drip edge flashings are installed whenever you have your roof replaced.
Wall flashings are formed sheet metal used to prevent water intrusion along the exterior walls of a building. For newly constructed buildings, wall flashings are typically covered by exterior siding and/or stucco. For existing buildings, the best approach is to use a 2-part flashing system that includes a counter flashing with sealant. (See Figure 3)
Underlayment is a secondary water barrier that acts as both temporary waterproofing for your roof before your primary roofing system (shingles, tiles, or metal) is installed and then as a backup waterproofing system after your primary roofing system is installed. (See Figure 4)
Starter shingles are the first course of shingles required to start the process of installing shingles up your roof. Starter shingles are installed at the eave of your roof to help prevent shingle blow-off during high winds. They are typically required to be installed along your eaves and gables (or rakes) to provide your home with the maximum wind performance. (See Figure 4)
Hip & Ridge shingles are the shingles that cover your hips and ridges. (See Figure 4)
Ice & Water underlayment is a self-adhered secondary water barrier that is typically used to provide additional protection in the valleys of your roof. Ice & Water can be used around roof penetration, along your roof's eaves and gables, or cover all of your roof's sheathing. (See Figure 4)
Attic ventilation is typically a 2-part system that consists of intake ventilation and exhaust ventilation. Intake vents are typically found on your soffits (under the eaves of your roof), where exhaust vents are typically found on top of your roof (either along your ridges or offset from your ridges). Florida Building Code requires a minimum 150:1 ratio of ventilation area to attic area. The ventilation area is split between your intake and exhaust vents. A properly ventilated attic not only meets Florida Building Code, but it can reduce the load on your home cooling system and extend the lifespan of your roof. (See Figure 5)
Typically, a minimum of 6 nails are required to fasten each full shingle.
We recommend a 4 step process:
A system warranty refers to the installation of multiple roof components from the same manufacturer. Manufacturers offer extended warranties for using several components because they are specifically designed to work together and maximize the lifespan of any product when installed correctly.
After a roof replacement, you should receive two warranties. One from the manufacturer for the materials used and the second from the contractor to warranty the installation of those materials.
