The demand for roofing will surpass $19 billion by 2021. Older roofs are being replaced at a torrid rate in Sarasota.

If you’re thinking about joining the crowd, you have to ask how long does an asphalt roof last?

The answer can be found by knowing the early warning signs and cost. This article will help you decide the best path for your roof needs.

How Long Do Asphalt Roofs Last?

The simple answer is a range from 15 to 30 years. Asphalt roofs are affected by temperature, wind erosion, and annual upkeep. A roof with constant debris from trees will not last as long as an asphalt roof with zero obstructions.

For four out of five homes in the United States, asphalt is the choice for roofs. It’s lightweight, visually appealing, and durable.

Some of the more expensive and modern asphalt shingles are advertised as lasting up to 50 years in ideal conditions.

Here is a breakdown of certain types of roofing materials and their lifespans:

  • Metal – It’s not lightweight, but metal can last anywhere from 40 to even 80 years.
  • Wood – Wood is an expensive choice that can last 30 years in ideal conditions. It’s not the best choice for areas with heavy precipitation.
  • Asphalt – As mentioned earlier, asphalt can last up to 50 years if it’s a high-quality composite.
  • Concrete and Clay – These materials have been known to last up to 100 years, but are expensive, heavy, and they can only fit the specific architecture.

Alternatives to asphalt have limitations based on price and fit. Replacing a roof with asphalt is a perfect way to make the house look nice and protect it.

What is Asphalt?

Asphalt is a stick petroleum substance used to protect roofs from water. It primarily has two types – fiberglass or organic.

The organic asphalt shingle has a combination of ingredients including paper and wood fibers. The concentration of petroleum is higher with these shingles. They also do better in colder climates.

Fiberglass shingles have a base layer of glass fiber that helps waterproof and fireproof them. Warmer climates like California use these types of shingles to help homes avoid wildfire damage.

Early Signs You Need to Replace the Roof

Unless you are the one who originally installed the asphalt roof, it might be difficult to accurately date. Sometimes a seller will have information or paperwork disclosing the age of a roof.

A professional inspector will be able to run a complete and thorough evaluation.

Look for these signs on your roof. These visual cues reveal it’s time to replace it.

  • Missing or cracked shingles
  • Asphalt particles in the gutters
  • Dark streaks, stains, or algae on the roof
  • Curling shingles
  • Visible leaks in the roof or inside the home
  • Shingles without any granules
  • Roof rot
  • Bowing or sagging roof

These are the most visual and noticeable signs of a roof in need of repair. Roofs can appear to be fine but once you or an inspector touch the shingle, it may disintegrate in your hand.

What Shingles to Buy?

The roof is rotting and it’s time to call an expert. They are going to ask what types of shingles do you want. Know the difference and types before making the choice.


Strip shingles are generally considered to be an economical choice. The lightweight and flat appearance make it the popular shingle.

Their lifespan can be up to 25 years, but three-tab shingles may last as few as 10 years.

Purchasing these shingles for a “forever home” may not be the best option.


Thicker and more durable than strip shingles, dimensional shingles are dual or multi-layered materials.

The lifespan is about 30 years but can go much longer in ideal weather conditions.


As the name implies, these are more expensive shingles with extreme durability and the possibility for creative designs.

Premium shingles are high-quality composites designed to last for 50 years or longer. More expensive homes or mansions might have premium shingles.

Maintenance and Warranty


Gutters and drains need to be regularly maintained and inspected. A roof is no different.

Most people are not trained or educated in the roof inspection. A skilled professional can evaluate your home or business twice a year and explain any actions that need to be taken.

Storms and other events that could damage your roof should always prompt inspections. Moving quickly could help an insurance claim or save you from water damage inside the home.

Some maintenance required might be replacing individual shingles, clearing off debris, or fixing the structure underneath the shingles.

Even if your roof doesn’t look damaged, it’s better to have it checked and eliminate worry. The worst problems are sometimes the toughest to spot.


Some manufacturers have warranties for their shingles. This will normally be for high-end products.

A roofing professional may also offer a warranty you can purchase. This purchase gives the buyer confidence that damage or errors during installation will be corrected.

Check packages or warranties that come with the products available.

Roofing Cost

The cost of installing an asphalt shingle roof in Sarasota ranges in price depending on the type of shingle.

The old roof removal costs alone can range from $40 to $100 per square foot. Expect to pay between $150 and $200 for the installation of your new shingle roof.

Here are estimates of what you may pay for your home:

  • Single-story home – 1,400 sq. ft.
    • Strip Shingles – $4,000-$9,000
    • Dimensional Shingles – $5,000-$12,000
    • Premium Shingles – $7,000-$14,000
  • Two-story home – 2,500 sq. ft.
    • Strip – $7,000-$12,000
    • Dimensional – $11,000-$24,000
    • Premium – $17,000-$32,000

It’s easy to see how cost can go up quickly with a bigger home. These are estimates that don’t factor in multiple levels to your roof, driving distance, or pitches.

The budget you reserve for a new roof should always include the cost to tear down your old one. Unless you have skills to tear the shingles down yourself, save yourself the hassle.
