Most homeowners don't think about all the components that make up the roof of their home, but there's a lot going on underneath your shingles. The shingles are the outermost layer of your roof and they help protect you from the sun's rays, rain, snow, and wind. Digging deeper, there's another layer of protection between the roof deck and the shingles: underlayment, which plays a vital role in helping protect your home from moisture damage.
From hurricanes and hail to tornadoes, roofers face unique challenges protecting storm-damaged roofs—especially during unprecedented times such as shingle supply challenges facing the entire industry.
Roofs are the first line of defense against the elements, both for full-time homes and smaller outbuildings. Sheds, garages, workshops, gazebos, pool houses, and other small structures need the same kind of protection as houses, though the job of shingling sheds differs from shingling houses in several ways.
When it comes time to talk to a contractor about doing a residential roof repair or replacement, it's good to know the different parts of a roof and the components of a roofing system.Important Structural Components Below the Roof
