When To Replace Roof: Signs, Lifespan, & More

If you have a family that loves you, a few good friends and a roof over your head, you are richer than you think. A quality roof epitomizes the beauty of a well-crafted and fully functional home. Individual shingles might need replacement over time. But an entire roof replacement project depends on significant damage to most parts of the roof. 

The damages could be due to wear and tear, roofs meeting their life expectancy, or poorly installed roofs. You must understand subtle signs to look out for to consider replacing your roof.

Knowing what to look for is the first step in determining whether it is time to replace your roof. Below are five signs that your roof needs to be replaced. 

Consider the Roof’s Lifespan

A roof’s life span depends on numerous factors but primarily the quality of the material. The average lifespan of a roof usually ranges between 25 to 30 years. However, its life expectancy deteriorates with unfavorable weather conditions, poor maintenance, or installation procedures. 

Consider inquiring about your roof’s lifespan before buying the roofing materials. Roofing experts could help you understand which materials best fit your environment or home’s style. The most common roofing type, asphalt shingles, have a lifespan of up to two decades

Proper roofing maintenance elongates its life expectancy. Thus, ensure you understand how to inspect and care for your roofing needs. In contrast, wooden roofs can last up to 30 years with proper maintenance. 

Understand the different factors that could influence your roof’s lifespan. 

Installation Quality

Good quality roofing installation ensures a brilliant roofing result and secures your home. You won’t have to worry about losing money and time through minor repairs, or rectifications taht could be avoided with proper installations.

If you find missing or lifted shingles after an installation, the installation wasn’t done as per the required standards. Installation mistakes could also cost you an entire roof replacement plan. Use professional roofing experts to avoid such errors and give your roof the best chance for increased longevity.  

Quality of the Roofing Material

Be careful when choosing your roofing materials. Research your supplier using their peer and client reviews in the market. Poor quality materials degenerate quickly and don’t provide adequate protection to the home of the roof shingles. 

Also, choose the right roofing material type. Asphalt shingles last up t 20 years, while clay or cement roofs last for 100 or 50 years. 


Weather elements like snow, heavy rain, or excessive heat during the changing seasons affect the roof’s deterioration. Some area manufacturers are keen to include specific protection layers that delay the degeneration process. Consult your area experts to understand more about the effects of heat and pressure on your roofs.

Drastic weather changes could cause the shingles to crack or yield to expansion and contraction. This chipping makes the shingles less resistant to winds and more susceptible to dampness. In turn, it affects the roofing structure and quality. If not promptly and effectively handled could cause further damage leading to roof replacements. 


Regular roof inspections allow the homeowner to monitor the roof’s performance against the expected standards. It also keeps the roof properly maintained through quick repairs of cracked shingles. 

Leakages and Water Damage

A leaking roof is one of the worst nightmares a homeowner can face. First, you must ascertain the leak’s source and extent of damage and what you can do as a temporary and permanent measure. 

Several problems can lead to leaks, but a failing or aging roof is the most common. The seals of an aging roof that keep water out begin to fail. Eventually, water seeps into and past the underlayment and through to the ceilings, walls, attic and insulation. It affects your home’s comfort and damages the affected parts. 

Smaller leak points may require partial or focused roof repairs. But if numerous shingles are affected, you must plan to replace your roof because the dampness and moisture could cause the formation of algae, whose effects are much worse. Routine roof inspection and maintenance is the best way to prevent future roof leaks.

Sagging Roof

A sagging roof is a worrying sight for any homeowner. It usually has a curved or wavy appearance instead of a straight one. A variety of things cause a sagging roof: 

  • Water damage – if the roof is not correctly distributing water, then the excess moisture can cause the roof to rot or decay 
  • Using undersized materials like using undersized rafters
  • An excessive weight on the roof can weaken the structure and cause structural damage due to stress
  • Old age can cause a structure to break down and start to sag, forcing you to get the entire roof replaced

When designing your home’s roof, you must understand your roofing needs, purpose, and choice of roofing materials. It eliminates such problems by assuring you of having the right tools for the job. 


Roofs take a beating from the weather during different seasons. The fluctuating temperatures and changing humidity often add to the roof’s degeneration. Also, installing the wrong type of roof in an area increases the chances of decline and will force you to replace your roof sooner than you think. 

The differences in the heat and pressure in the environment accelerate the aging process. It’s difficult to notice this wear during the early asphalt shingle years, But with time, the damage becomes apparent when you must replace your roof. The only prevention measure is to take proper care and get your roofing choice and installation right for your home’s comfort. 

Some deterioration signs that show you need to plan for a roof replacement are:

  • Curling or clawing of shingles due to both aging and excessive heating of the roof
  • Missing granules and bare spots resulting from exposure to heat and sun lead to protective granule loss in the roof system and can cause roof leakages
  • Cracked shingles – Having several cracked shingle signify the roof is rapidly losing its  functionality
  • Lifted shingles show they’ve been affected by harsh weather or other factors. It’ll be easier for water or moisture to escape into the deck, thus causing damage to the house

To avoid rapid roof degradation, avoid using poor-quality roofing materials. Also, proper maintenance and roof cleaning delayed the degeneration process of the granules. A regular inspection enables you to resolve any damaged individual shingle before it creates a bigger problem.
