We Work With Several Types Of Roofing Systems
Each type of roof requires slightly different components. Let’s take them one at a time:
The most common type of roof for residential homes, sloping roofs (i.e., roofs with slopes of more than 25%) are easy to maintain, especially given the wide fluctuations in temperature we experience in North Carolina.
Roof system components for sloping roofs are as follows:
- Roof Covering - Consisting of asphalt, slate, metal, or wood shingles
- Sheathing - Wood planks or sheet metal that are attached to the rafters covering a house or other building
- Structure - Rafters and trusses constructed to hold up the roof
- Flashing - Sheet metal or other material used to seal various joints and valleys to prevent water leaks
- Drainage - Design features of roofing systems such as shape, slope, and layout that enable it to shed water
Types of Shingles and Roofing Materials
When it comes to choosing one of the roofing systems that are right for you, the most significant (and fun!) decision you, as the homeowner will make, is about the type of shingles you want. Are you focused primarily on price or do you want to get a high-end look? Are you willing to spend a bit more on materials that will hold up longer?
However you answered, here are your basic options when it comes to roofing systems and shingle types:
Slate & Tile Shingles
Wood Shake & Cedar Shingles
A bit more complicated are flat roofs, which can require a good deal of maintenance. Flat roofs require regular cleaning to prevent leaves and debris from clogging gutters. The sun can cause damage too. Because of these factors, flat roofs need to be replaced more often (every 15 years or so). Roof system components for flat roofs are as follows:
Built-Up Roof (BUR) Membranes
A sticky layer of tar (the membrane) covering the roof that is typically covered with gravel.
Metal Panel Systems
Like sloping roofs, flat roofs can also be covered with structural metal panels.
Polymer-Modified Bitumen Sheet Membranes
Composed of alternating levels of fabric that carries hot polymer-modified bitumen rolled out over the roof(similar to sod you might have laid down around your property).
Spray Polyurethane Foam-Bases (SPF) Roof Systems
A spray application weatherproofing that can be installed in various thicknesses to provide an additional slope for drainage. What type of roof membrane system is right for your flat roof will depend on the level of weatherproofing you need based on the location of your home. An experienced roofer will help you determine what’s best based on your home’s specifications.
