How Do You Know When Your Roof Needs To Be Replaced?

Most homeowners only figure out they need a new roof after spotting a leak in their ceiling. Roof leaks could be a result of numerous roofing problems, and only periodic roof inspections by a professional roofer can pinpoint those underlying issues. So, how do you know when your roof needs replacement and not minor repairs?

Tips To Help You Determine If You Need A New Roof

Replacing an aging roof is a project many homeowners would want to put off. It is often a significant investment which costs thousands of dollars or more. The overall cost of roof replacement will vary depending on the roofing material and what your local contractors charge in your area.

Overall, age is the biggest determinant when deciding to replace your roof. Most roofing experts agree a typical shingle roof will last around 20 years. The overall lifespan will also depend on whether the shingles were installed over an existing layer of shingles or the old roof was torn off before installing a new one. If you have more than one layer of shingles on your roof and it is more than 20 years old, chances are you need a new roof.

Other signs you need a new roof include:

  • Low-quality materials or installation on the existing roof
  • Multiple curling or missing shingles
  • Damaged or broken flashing
  • Ice damming
  • Discolored walls and ceilings
  • Unwanted pests in your home

Other than these, if you recently replaced your current roof, there are high chances you won’t need to replace it anytime soon. However, if you’re not aware of when it was last replaced, it can prove difficult to know the age of your roof. Fortunately, you can hire a professional roofer to carry out a thorough inspection of the roof and estimate its remaining life.

Expected Lifespans of Different Roofing Materials

Depending on the existing material on your roof, here is the expected life expectancy of your roof:


Asphalt shingles are among the most affordable roofing materials today. They are also easy and affordable to install. On average, asphalt shingle roofs last around 20 years before they require replacement. However, strong winds and violent storms can cause shingles to deteriorate faster and require replacement before the projected lifespan elapses.


Metal roofs are increasingly becoming popular for residential homes, especially in areas prone to wildfires. The most common metals used are steel or aluminum, although zinc and copper can also be used. Metal roofs are virtually maintenance-free and offer excellent durability.
With proper installation, metal roofs offer a lifespan of 30 to 50 years. In favorable weather and regular maintenance, some metal roofs can last up to 70 years or more. To prolong the lifespan, have your roofer regularly inspect your metal roof to ensure any sealants and fasteners are intact.

Wood Shingles

Wood shingles are made from thin, wedge-shaped slices of natural wood, such as yellow pine or cedar sawn from logs. These shingles provide a very aesthetic roof but are relatively tricky to install and maintain. You should also be cautious if your area is prone to fire hazards.

On average, wood shingles last about 25 to 30 years, although you can achieve longer lifespans in locations which experience mild weather conditions and the roof remains free of debris. With proper maintenance, wood shingle roofs can last for as long as 50 years.


Clay tile roofs are popular for their incredible strength and durability. Traditional tile roofs are made from terracotta clay, but concrete tiles and ceramic tiles made of fired clay are equally popular. However, tiles require sturdy roofing framing to sufficiently hold the weight.

With proper installation, your tile roof could as well be the only roof your home will ever need. Clay tiles typically last 100 years or more. These roofs don’t decay as wood shingles, and they don’t shed off mineral grains, a situation often associated with asphalt and composite shingles.
