Whether remodeling or simply curious about your home’s most prominent protective layer, understanding basic roof anatomy empowers homeowners to converse knowledgeably with contractors and address minor issues independently. At C&M Roofing and Construction, we believe education builds confidence, so we’re sharing this introductory “Roofing 101” guide to roof components for any roofing novice.

Roof Deck

Forming the base, this substrate commonly includes plywood or oriented strand board (OSB) sheathing installed over roof framing members. The deck creates a sturdy platform supporting additional weather barrier layers and roofing materials above. Looking for decking issues involves inspecting its rigid, intact condition.

Underlayment

Also called felt paper or synthetic sheeting, underlayment is installed beneath shingles or tiles providing a secondary water-resistant layer. Popular Grace Ice & Water Shield self-adheres around difficult-to-flash areas like eaves, valleys, and protrusions. Check for wrinkles, gaps, or tears that need to be repaired before final roofing installation.

Drip Edge

This aluminum extension channels water away from vulnerable fascia boards and into gutters. Installing drip edge occurs before underlayment along eaves and rakes. Signs like rusting or crimping merit professional evaluation for replacement tying into a successful roofing system. 

Flashing

Critical materials like step flashing, valley flashing, and membrane flashing divert water around interruption points to prevent leaks. Corrosion indicates ineffective flashing warranting renewal. Experienced installers ensure proper overlap and sealant adhesion for long-term performance.

Vents

Ridge vents, soffit vents, and turbine vents optimize attic ventilation removing moisture and controlling temperatures. Periodic cleaning fends off mold risks while minimizing ice dam issues forming along eaves. In cold climes, sufficient intake/exhaust vents prove vital.

Roofing Material

Beautiful yet robust asphalt shingles, clay/concrete tiles, or metal roof panels withstand environmental hazards as the finishing surface. Age signs spanning curling, cracks, or tears necessitate roofing material removal and re-cover by specialty contractors like C&M Roofing.

Gutters

Completing the water management system, seamless or sectional gutters funnel discharge into downspouts directing it away from foundations. Debris clogs or detached gutters undermine roof and home protection requiring professional cleaning/repair services too.

We hope this primer on basic roof anatomy proves helpful in understanding your home’s most integral barrier. C&M remains available year-round for all your roof maintenance, replacement, or repair needs.
