Asphalt Shingles are Most Popular Roofing Material

Asphalt shingles dominate the US roofing industry, accounting for more than 70% of all residential, sloped roofs including new construction and replacements.

Why are they so popular? There are many reasons but the top three are low cost, ease of installation and longevity.

Shingle roofs are more affordable than most other roofing types.  They are proven to last 15-30 years, depending on climate, proper attic ventilation and how often regularly roof maintenance is done. They are also available in a wide range of styles and colors and are generally easy to clean.

Keep in mind the sunnier the climate, the shorter the lifespan of the average shingle. One of the ways to extend the lifespan of an asphalt roof in a sunny climate is to choose a solar-reflective, light colored shingle designed to reflect solar radiant heat and UV radiation.

How do I know it’s time to replace my current asphalt roof?

If there are no visible signs of damage and the roof isn’t leaking, you probably don’t need to replace your roof. Warning signs of asphalt shingle failure –or impending failure — are:

  • Cupped or curled shingle edges
  • Cracks where shingles have become brittle
  • Recurring leaks
  • The appearance has become dull through loss of granules

Cupped shingles can also be a sign your attic isn’t properly ventilated and should be inspected. And then there’s this: If you don’t like the way your roof looks, that’s a great reason to replace the shingles.
