How Long Do Asphalt Shingle Roofs Last

Asphalt shingle roofs are the most used roofing material in America for good reason. They are cost-effective and hassle-free to install. However, since replacing or repairing your asphalt shingle roof is a significant investment, it is worth knowing its expected lifespan before you make a decision.

Types of Asphalt Shingles

Your choice of asphalt shingles has a significant effect on the expected lifespan since each type has a different service life. Here are the three main types of asphalt roof shingles:

  • Three-tab shingles – These are lightweight shingles designed to last for at least twenty years while retaining their clean and typical look. They are the most affordable option and, thus, have limited aesthetic qualities.
  • Dimensional shingles – The multi-dimensional aspect of these shingles helps add strength and durability, while adding texture and enhancing appearance. The extra strength from joining multiple shingle layers together delivers a thirty-year or more lifespan.
  • Architectural shingles – Also known as luxury shingles, these roofing materials are much thicker and create a more resilient and denser roof. This premium asphalt shingle roof can last from 25 to 30 years.

Signs Your Roof Is Nearing the End

Most people come to recognize it’s time to repair or replace their roof after spotting signs of water damage or leaks in their ceiling. Here are other telltale signs that indicate your roof is nearing the end of its service life:

Roof age

Most roofing experts affirm that typical asphalt roof shingles will last for at least twenty years, provided the installation was done correctly including proper ventilation. So, if you are experiencing leaks and your roof was installed more than twenty years ago, then a roof replacement is worth considering.

Water damage

If you notice water spots in your ceiling or exterior walls, it could indicate a leaky roof. Spongy and soft wood decking could also indicate water damage.

Inspect Roof Shingles

You should always monitor the state of your roof to ensure it remains in great shape, particularly after any adverse weather events like hurricanes or storms. Check whether your shingles are lying flat on your roof and not buckling or curling. Missing shingles could also show that your roof is failing. You can inspect your attic to see if daylight is coming through your shingles.

Poor roof flashing

Check that the flashing placed around chimneys, vents, and skylights does not have any cracks that could result in leaks. It is recommended to switch from tar and roof cement flashing to metal flashing systems for extra resilience.

A Drooping roof

If your roof is sagging, it shows that you must do a quick replacement before it leads to more costly damage to your home. Your roof must be in excellent condition to enable easy water run-off. Once it starts to sag, the situation will only get worse, and you must take quick action.

Other Factors Affecting the Lifespan of Asphalt Shingles

  • Quality of roof installation – A sound installation job ensures your roof lasts longer, while a bad installation may even void your warranty.
  • Proper ventilation – A hot, stuffy attic can adversely affect your roof’s lifespan as it overheats the shingles.
  • Roof maintenance – Practicing proper roof maintenance with regular inspections and repairs can unearth issues and help you solve them before they translate into massive problems.
