Things To Consider When Replacing A Roof


A roofing replacement project requires extensive knowledge and experience. Keep in mind that your roof plays a vital role in providing protection and comfort to your home. That’s why you should make sure you work only with a licensed, insured, and reputable roofing contractor to install your new roof.

A good roofer will provide an honest assessment of your roof’s current condition and whether or not you actually need to replace it or make some repairs. In addition, your contractor should inform you about the best roofing materials available for your needs and should be transparent about costs, work timeframe, and cleanup.

In today’s blog, we will discuss some important things to consider when considering replacing a roof, including the expected lifespan of different roofs, signs that you need a new roof, and other important considerations once you decide to replace your roof. Read on.

Factors That Can Affect Your Roof’s Lifespan

The expected lifespan of a roof can vary greatly depending on several factors. These include the following:

Selected Roofing Materials

One of the biggest factors that can affect the roof’s lifespan is the roofing material used for your roofing system. Not all materials are designed equally. For instance, asphalt shingles can last up to 20 years while metal roofing systems can last up to 50 years or more. Clay and concrete tiles are also known for their durability and longevity, with a lifespan of up to 50 years.


Bad weather is the number one enemy of your roof. Yes, your roofing system is also designed to withstand elements like strong winds, hail, and heavy downpours. But, eventually, these harsh elements can take a toll on your roof’s condition.


Another factor is the roof’s pitch or slope. Professional roofing contractors can help determine the right pitch or slope for your home or property. An experienced roofing contractor may recommend installing flat roofs for low slope roofs.


Poor attic ventilation can cause several problems. This can lead to structural damage and can ruin the entire roofing system. Be sure the attic has adequate ventilation to avoid these problems.


Like ventilation, the roofing system also requires proper insulation to help regulate airflow and maintain the ideal temperature.


Finally, the lifespan of your roof will also depend on how you take care of it. Prolong the lifespan of your roof with regular inspection and maintenance.

Signs That You Need A New Roof

Some roof problems can still be fixed with minor repairs. But, when you see these signs, it’s time to consider getting a new roof:

Old Roof

When you’re dealing with an old roof, you probably need to replace it. So, when you see your neighbors having their roofs replaced with new shingles or metal roofs, it may be time to consider getting a new roof. Reroofing or installing new shingles to existing shingles is possible in some cases. However, this method is not usually recommended by professional roofers.

Worn or Curling Shingles

Another warning sign to watch out for is worn or curling shingles. Moisture is usually the common cause of curling and buckling shingles. Always check the roof deck or the roof sheathing as these areas absorb moisture.

Damaged Valleys

Valleys and valley flashings are among the weakest spots of the roof. Their main function is to control water flow to avoid water pooling and clogging. Damaged valleys often result in leaks. Applying sealants is just a temporary fix. If you want a long-term or more permanent solution, you might want to consider a new roofing installation.


A sagging roof is also a potential sign that your roof needs replacement. Some of the common causes of a sagging roof include water damage, poor ventilation, excess weight, and installation problems. Some roofing contractors can try fixing a sagging roof by installing angled braces or chains to provide support. However, these are just temporary fixes.
