Whether you’re experiencing leaks, missing shingles, or simply want to assess the overall condition of your roof, this article will provide you with the necessary steps to determine if a roof replacement is necessary. Read to the end to get the most out of it.

10 Signs That Are Indicative That Your House Needs Roof Replacement 

When it comes to determining whether your roof needs a replacement, there are several indicators to look out for and these include; 

Moss and mold on the roof

One of the tell-tale signs is the presence of moss and mold on the roof. Moss and mold thrive in moist environments, and their presence on your roof indicates that water is trapped or not draining properly. 

Not only does moss and mold make your roof look unsightly, but it can also cause structural damage over time. It is important to address this issue promptly to prevent further damage to your roof and potential leaks.

Attic leaks

If you notice water stains or dampness in your attic, your roof will likely develop leaks. Various factors, such as damaged flashing, cracked shingles, or faulty sealing around vents and chimneys, can cause these leaks. 

Ignoring these leaks can lead to significant damage to your home’s interior, including the growth of mold and mildew, as well as damage to your insulation. Therefore, it is crucial to consider a roof replacement.

Cracked shingles

Shingles can become cracked due to exposure to harsh weather conditions such as strong winds, hailstorms, and extreme temperature changes. 

Cracked shingles not only compromise the aesthetic appeal of your roof but also leave it vulnerable to water penetration. 

When shingles are cracked, they lose their ability to effectively protect your home from moisture. 

This can lead to water leaks, rotting of the underlying materials, and even structural damage. If you observe cracked shingles in your roof, it’s time to call the roofing company.

Sagging roof

A sagging roof is a serious issue that requires immediate attention and indicates the need for a roof replacement. 

It can be caused by various factors, such as weakened or damaged rafters, excessive weight on the roof, or water damage. A sagging roof can compromise the structural integrity of your home and pose a safety risk.

Rotting underlay

The underlay, the roofing felt or membrane, is a protective layer between the shingles and the roof deck. 

Over time, exposure to moisture can cause the underlay to rot or deteriorate. This compromises its ability to effectively repel water and protect your home from leaks. 

If you notice a rotting underlay, such as sagging or spongy areas on your roof, it is important to consider a roof replacement to prevent further damage.

Grit in the gutter

If you notice small granules from your shingles accumulating in the gutter, it could be a sign that the shingles are deteriorating and losing their protective layer. 

This can expose your roof to the elements and lead to further damage. At this stage, the best thing to do is replace the roof.

Curling and buckling of shingles

Over time, exposure to sunlight and weather conditions can cause shingles to warp and lose shape. This can result in water pooling on the roof and seeping into the underlying layers. 

Suppose you notice any curling or buckling of shingles. In that case, a professional must inspect your roof to accurately assess its condition and determine if a replacement is necessary.

Missing shingles

Missing shingles are also a clear indication that your roof requires replacement. Whether strong winds have blown off them or have simply worn out over time, missing shingles leave your roof vulnerable to leaks and further damage.

If your roof is more than 20 years old

If your roof is over 20 years old, you need to consider a replacement. While a well-maintained roof can last longer, most roofs have a lifespan of around 20-25 years. 

As a roof ages, it becomes more susceptible to wear and tear, leading to potential leaks and other issues. 

If your roof is reaching or has surpassed this age threshold, it is best to consult a roofing professional who can accurately assess its condition and recommend replacement if necessary.

Light coming through the roof.

Light coming through the roof can mean an issue with the integrity of your roof’s structure, such as damaged shingles, cracks in the roof deck, or gaps in the flashing. It can lead to water penetration and severe damage if left unaddressed.


Now that you know how to check if your roof needs replacing are you going to take action? You better, if you have to.

It is important to regularly inspect your roof to determine whether it needs replacing. Following the steps outlined in this guide, you can easily identify signs of damage, such as missing or cracked shingles, sagging areas, or attic leaks on your ceiling. 

It is important to address these issues promptly, as a damaged roof can lead to further structural damage and potential leaks. 

If you notice any of these signs, it is advisable to consult a professional roofing contractor who can assess the condition of your roof and provide recommendations for repair or replacement.
