Parts of a roof
A roofing system includes more than the shingles visible from the street. The layers beneath them (deck protection, leak barrier, starter strips, attic ventilation, and ridge caps) work together to protect your property. Explore the diagram below, and bring your questions to us; we can explain what applies to your roof and how it fits into a repair or reroof plan.
Why it matters
Seeing how the layers work together can make inspection findings and project recommendations easier to understand. Ask us what your roof needs and we’ll show you.
