There are several reasons why asphalt shingles are the most popular roofing material in the country. They’re cost-effective, easy-to-install and durable enough to handle a wide range of climates.

What are the different components that make up an asphalt roof? StormROOF Systems, LLC, your trusted roof repair contractor, lists them in this blog post.

 Asphalt Roofing System

  • Asphalt shingles – Since asphalt roofing shingles’ main function is to repel rainwater, it’s important to choose high-quality roofing shingles.

  • Underlayment – The underlayment acts as a secondary barrier against moisture in case water manages to infiltrate your roof.

  • Ice and water barriers – The leak-prone areas on your roof such as the roof valley —the section where two roofs meet and water is diverted to before flowing to the gutter system—need additional ice and water barriers.

  • Hip and ridge products – These bridge the two roof slopes together to prevent water from infiltrating the asphalt roof. And like asphalt shingles, they serve a cosmetic function as well by putting the finishing touches on an asphalt roof.

  • Ventilation system – All roofing systems should have adequate ventilation. Otherwise, Otherwise, humid air becomes trapped inside, creating a damp environment that’s the perfect breeding ground for mold. How many air vents does an asphalt roof need? It depends on the size of your attic. In general, there should be a square foot of net free area (NFA) (the area through which air can pass through) for every 300 square feet of floor area for attics with a vapor barrier. And if your attic doesn’t have a vapor barrier, it will need a square foot of NFA for every 150 square feet of attic floor space. If you’re not sure if your current roof has enough ventilation, have one of your local roofers conduct a roof inspection.

  • Starter strip products – These prevent shingles from being dislodged by wind uplift, which would allow water to seep into the shingles.
