Additional roofing materials utilized in replacing your roof in addition to your roofing shingles.

Materials for Roof Replacement

This is much more to your roof than the asphalt shingles that are the final layer to your roof.  Sure, whether the old 3 tab style of the architectural shingles of today, the shingle layer is the first layer of protection and beauty that comprises your roof.  Every part, or layer, of your roof performs a specific job in keeping your family and you protected against the elements presented by the weather seasons.  When a new roof is installed on your home just about all of your roofing components and various accessories are replaced or at least a good amount of them.  What are the components besides the obvious roofing shingles?

Roof Decking

 The plywood wooden boards that make up the framing of your roof are what your shingles and other roof components are installed upon.  When replacing your roof your contractor will inspect and replace those boards as necessary if they find rotting boards or other issues.  Until your roofer removes the existing shingles he won't know if or how much of the roof decking needs to be replaced.  Before the asphalt shingles can be installed the integrity of the roof decking must be determined to be sound and ready to handle the installation of your new shingles.
​

Roof Flashing Materials

Flashing is placed anywhere your shingles are up against a component on your roof such as skylights, a chimney, a wall, or in the roof valleys where two different slopes contact one another.  You will see them around just about any component you see on your roof such as roof vent boxes.  As long as your roof flashing isn't rusted and the metal is still fine then the roof flashing will likely not need to be replaced.  But, if you are switching from the old 3-tab roofing shingles and upgrading to the multi-dimensional architectural asphalt shingle then your roof flashing will need to be replaced.

​

Roof Underlayment

When replacing your roof the underlayment which is a material that provides additional protection to your roof decking will be replaced.  Roofing underlayment comes in various weights (thicknesses) and is typically a felt or synthetic material.  This material WILL be included when you contract for a new roof or when replacing an existing roof.  This material is provided to protect your roof decking.

​

Drip Edges

Drip Edge is a specific type of metal flashing that is installed on the edges of your roof to aid in controlling the water flow away from your fascia and other roofing components.  This component, the drip edge, must be replaced when you install a new asphalt roof per code.  

​

Ice and Water Shield​

Every time it rains the valleys of your roof need to sustain the flow of a much greater amount of water as these valleys are designed to move the water in the right direction down your roof.  The Ice and Water shield is a waterproof membrane that is utilized to protect those valleys as well as other areas that receive a lot of water from the elements.  This material will have to be replaced when replacing your roof.

​

​Ridge Capping

Your roof's ridge capping consist of the trim installed at the peeks of your roof where two slopes of a roof meet.  They are already bent to conform to your roof ridges and they are thicker than the installed shingles.  Roof capping is another component of your roof that must be replaced when your roof is being replaced.  

​

Roof Vents

In order to provide the best environment for your new roof and to keep its life expectancy, your roof will have a venting system.  It may utilize vent boxes, a roof exhaust fan, or may your venting system may consist of ridge vents.  Regardless of what type a venting system is utilized your attic must be able to breath and requires proper ventilation.

​

​Roofing Pipe Boots

Any pipes emanating from your roof need a pipe boot installed so that water doesn't run down the pipe into your attic and subsequently into your home.  A pipe boot is a rubber boot made of synthetic material that goes around any roof pipe penetration in order to prevent leaks.  When your roof is replaced the rubber pipe boots must be replaced.
