A residential shingle roof is a layered system, and each component serves a specific purpose. Understanding how these parts work together helps you identify potential issues early and have more productive conversations with your roofing contractor.
The Foundation Layers
Roof decking — typically plywood or OSB — forms the structural base that supports every other layer. A leak barrier membrane is applied over the decking in high-risk areas such as eaves, valleys, and chimney surrounds to protect against ice dams and wind-driven rain. Roof deck protection, a secondary underlayment, then covers the full deck surface as an added moisture barrier. Armored Roofing and Construction evaluates all three layers during every assessment. With three generations of roofing experience and over 40 years in the trade, we know exactly where to look for hidden deterioration that leads to expensive repairs.
Surface Protection
Starter strips are installed along the eaves and rakes with pre-applied sealant to reduce the risk of blow-offs at the roof’s most wind-vulnerable edges. Asphalt shingles go on next, built from a fiberglass base coated with asphalt and mineral granules. Not all shingles are created equal, which is why Armored Roofing installs GAF roofing products — recognized across the industry for performance and longevity. As a GAF Master Elite President’s Club contractor, we’re authorized to offer GAF’s Golden Pledge Limited Warranty, one of the strongest roof warranties available. Ridge cap shingles then cover the hips and ridges where opposing slopes meet, providing both protection and a finished appearance.
Structural Terms and Finishing Components
Flashing consists of thin metal pieces installed around penetrations like chimneys, vents, and skylights to divert water from vulnerable seams. The drip edge prevents water from curling back under the roofing material along eaves and rakes. Pitch refers to your roof’s steepness, which affects material selection and drainage. Dormers add light and space but create additional seams that need proper sealing. And balanced attic ventilation is critical to reducing heat and moisture buildup that accelerates wear from the inside. Armored inspects every one of these elements as part of our standard evaluation.
