When it's time to talk to a contractor about a roof repair or replacement, knowing the components of a roof and how they help protect your home can help you navigate the decisions you need to make throughout the process.
Your roof plays a crucial role in defending your home against the weather. Roofing felt is a protective layer under your shingles (or other roof covering) that helps keep excess moisture outside your home. Since your roof deals with all kinds of weather elements, like rain and wind, snow, and ice, it often needs all the help it can get. Here is everything you need to know about this roofing product including what it is, minor differences between kinds, and why your roof might need it.
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.
