A Whole-System Approach to Steep-Slope Roofing


For homeowners, installing a new roof does more than change the look of a home; it protects their family and belongings. It does so through a series of roof components that work together to form a complete system and help increase the performance of a roof.       

What are the Six Components of a Roofing System?               


1. Asphalt shingles provide the principle water-shedding surface and create the unique look that sets your home apart from others on the block. 

2. Underlayment provides an added layer of protection between the wood deck and the shingles, acting as a secondary water barrier. More information on underlayment can be found here.

3. Ice and water barriers protect the vulnerable parts of a roof− such as valleys, around chimneys and other roof protrusions− where water can flow.
4. Starter strip products are critical for proper shingle installation, and provide the first row of sealant needed to help prevent shingle blow-offs and water penetration.
5. Hip and ridge products complement the asphalt shingles and provide the finishing aesthetic of the roof.
6. A balanced ventilation system allows heat and moisture to escape from the attic. It also helps eliminate ice damming and premature shingle deterioration by keeping the attic temperature closer to the outside temperature. More information on proper ventilation can be found here.

The combination of these roofing system components provides redundancy, durability, and variety in look, style and color that is unmatched by competitive technologies.
