How do I know if my roof is at its end of life? You might find yourself wondering. It is essential to know the life span and condition of your roof because overlooking these can lead to costly repairs. In this article, we will explore the key signs that indicate the current state of your roof so that you can make informed decisions and allocate a budget for replacement accordingly.

The roof is often the most neglected part of a house. Since we expect roofs to have a life span of at least 20 years, we tend to forget all about them. We only pay attention once there’s a leak or we notice physical damage. But, if you want to avoid trouble down the road, you need to be mindful of the state of your roof today.

Regular inspections and proper maintenance will not only help you avoid expensive roof repairs but will also extend the life span of your roof. Regularly inspecting your roof and knowing what to look for will also let you know when it’s almost time to prepare for replacement.

Signs That Your Roof Is Nearing Its End


Your roof is meant to last many years. Whether you have shingles or metal roofs, they are designed to withstand harsh weather. But, years of wear and tear will cause the roof components to deteriorate. Understanding your roofing system will help you know when a roof needs replacing.

Granules in the Gutter

One of the early signs of a deteriorating roof is granular loss. This is especially true with shingles. These granules are a stone coating meant to protect the asphalt underneath. Losing too many granules will expose the asphalt to direct UV rays and cause it to dry, crack, and leak.

When you start seeing granules in the gutters, you’ll know that your shingles are getting old and might not be as effective. Once you closely inspect the shingles and you start seeing asphalt, it’s time to contact a roofing contractor.

Roof Shingles Are Starting to Curl and Blister

Another sign that your roof is nearing the end of its life is when there’s curling and blistering. It might not seem severe initially, but curling, cracking, and blistering might cause leakage, which will be a problem when the rain comes.

Consider consulting a professional roofing contractor at the first sign of blistering. When your roof has poor ventilation, there will be high humidity, which causes blistering. Low-quality shingles can also cause curling and cracking because they dry out faster.

Moss and Dark Spots

If your roof is made of brick tile and concrete, you must check for stains, dark spots, moss, and fungi. Most dark spots are caused by moss or algae, which is expected if the roof is not getting much sunlight or if you live in an area with a moist climate. In some cases, moss growth is not harmful. But there are cases when moss holds moisture and can damage your roof in the winter.

If you have metal roofing, stains and dark spots are usually a sign of corrosion and aging. Once rust sets in, it will start compromising the structural integrity of the whole roofing system until you’re looking at replacement.

Droopy or Sogging Spots

One sure way to tell if your roof needs replacement is sagging or droopy areas. This is a problem that requires immediate action so that it doesn’t end up causing further damage to the house. 

Sagging roofs could be a sign of trapped moisture or rotting boards. It could be a sign that your roof is weak and poorly installed.

Whatever the cause, you should engage a professional to rectify the problem. You don’t want your roof to collapse and injure anyone.

Know Your Roof’s Life Span

A roof’s life span depends on the type of material it is made from. It is essential to know what your roof is made of and when it was made to understand how many years you can expect from your roofing system.

If you have flat roofs, the life expectancy depends on the materials used on top. If your flat roof has asphalt coverings, you can expect that covering to last for about 10 years. Meanwhile, you can expect no issues in 40 to 50 years if you have rubber roofing. Slate and concrete tile roofs can last up to 100 years, and clay tiles can last up to 60 years.

Wood shingles are rot-resistant but can only last up to 30 years. Asphalt shingles will last between 20 and 40 years. But if you have metal roofs or fiberglass shingles, you can expect a reliable roof over your house to last for more than 50 years.

However, even the most durable roofs will not last forever. Many factors affect your roof’s life span. As such, maintenance and regular visual inspection is still vital.
