The roof of your home is more complex than you may realize. Yes, it does protect your home from the weather and its elements, but your roof consists of many sections that together make up the roof. There are multiple layers, each with a specific purpose, that combine to provide the perfect protection of your home. Understanding the different sections of your residential roof will make it easier to speak with roofing professionals to discuss any concerns you have on your roof before starting repairs.

 

Truss

Trusses are a huge part of the roof design. They are made of wood and are designed to be able to support the weight of the roof by transferring the weight evenly to the homes walls and support system. Trusses are designed to support not only the building material’s weight but also to withstand the weight of rainstorms and even snowstorms that may pass through your neighborhood. The design is not only functional for bearing weight but essential for the installation process. They have an open web design that allows for easy and flexible installation of your home’s electrical, plumbing, and heating.

 

Roof Frame and Decking

The first step in building a residential roof is to assemble the frame. This design will be the foundation of how the roof will be assembled, as well as add to the home’s curb appeal.  Once the frame is built, decking will be placed upon it to reinforce the structure of the roof and be the nail bed for the shingles that will be installed shortly. Decking is thin pieces of plywood that are laid flat along the roof’s frame.

 

Underlayment

Right after the decking is installed, the underlayment will be placed over it to add additional layers of protection against wind and rain.  Underlayment is a durable paper material that is saturated in asphalt. This step is extremely important to have on a Florida roof. Underlayment is a safety shield, protecting your home from wind and rain, in the off-chance that a shingle is broken or torn off your roof during a storm. When installing a sheet of underlayment, start at the bottom of the roof and roll the sheet upwards. As new sheets of underlayment are installed, overlap them slightly over the preceding sheet to help stop water from seeping between the underlayment sheets during a rainstorm.

 

Shingles

Shingles are the top layer of your residential roof and the most recognizable feature of the roof. Shingles are typically made of asphalt material and come in a variety of colors to match your home’s aesthetic. There are three common types of shingles used today:

  • 3 Tab Shingle: Most basic type of shingle and most cost-effective
  • Laminate Shingle: Similar to the 3 Tab shingle, but have a laminate finish to give a more appealing look to your roof
  • Premium Shingle: Premium quality material that offers higher protection from weather elements

 

Flashing

Flashing is one of the more difficult materials for homeowners to understand. Many Florida roofs have a skylight that allows for natural light to shine into your living space. Skylights jet out from the roof and need some material to help prevent any water from leaking inside. Flashing is a thin sheet of metal that is installed along surfaces that jet out from the roof pane, such as a skylight or chimney. The flashing is installed at a 90-degree angle between the underlayment and shingles, and rests up against the skylight.
