Home Maintenance 101: How To Tell You Need A New Roof

When your roof is doing its job — protecting you and everything in your home — it’s not something you probably think much about.

Having a sturdy and reliable roof helps keep you safe, so it’s best to be proactive about replacing your roof instead of waiting for an emergency situation.

Getting a new roof is a worthwhile investment since it can save you money in the long run. Making multiple repairs or waiting until you’re in a dire situation can drain your bank account quickly. Plus, a new roof also helps your home’s curb appeal – which if you’re thinking about selling, will give you an advantage. 

If you see one or more of these signs, it’s time to replace your roof. 


The lifespan of your roof depends on what it’s made out of and local weather conditions.

Asphalt shingles are the most common roofing material. Asphalt shingles typically last around 20 years but can last as long as 30 to 40 years. If you have architectural shingles and not the popular three-tab style of asphalt shingle, your roof is even more durable. 

If you have a slate roof, it can last 75 years or more! And if you have clay or concrete tile roofing, you’ll only have to get a new roof about every five decades. 

Look through your records to determine when your roof was installed and if it’s time for a new one, then make sure you choose the right type of roofing material for your house. 


A sagging or drooping roof is a sign it will eventually collapse. Needless to say, your roof needs to be replaced as soon as possible if it’s not straight, like it was when it was installed. 

Some causes of sagging are an excessive amount of weight on the roof — like from snow or ice — or too many layers of shingles. Overall, a sagging or drooping roof means the roof is not as sturdy as it should be and needs to be replaced. 


Over time, shingles can get damaged due to wear and tear from the weather. If the shingles on your roof are curled, cracked, or missing, get your roof professionally inspected.

A few damaged shingles here and there can be replaced, but other times, it’s worth it to get an entirely new roof since damaged shingles can make your roof more vulnerable to leaks or bigger issues eventually.


Moss, mold, and fungi often grow when a roof doesn’t get much sunlight or is locking in moisture. If you have moss growing on your roof, it’s important to know that it’s more than just unsightly — it’s causing damage. 

As moss grows and spreads beneath shingles, it can allow moisture to seep into your home. This moisture can lead to wood rotting, meaning you’ll have to not only replace your roof, but repair the interior of your home.

Moss also strips away protective oils that are on your shingles, making them susceptible to cracking and damage quicker than they otherwise would be, which lessens their lifespan. 


A leak is one of the more obvious signs that your roof needs to be replaced. Leaks are hard to miss, but another sign of a leaky roof is interior water damage. Water damage is likely from your roof if you have water spots, streaks, or water stains in your attic, ceiling, or at the top of your walls.

Immediately call a professional if you have leaks or think water damage in your home is coming from your roof. A professional roofing contractor can let you know if the water damage is coming from your roof and if it needs to be replaced. 


Getting a new roof is a big investment, so it’s a good idea to get a professional opinion before you take action. If a professional inspects your roof and tells you that simple repairs aren’t enough to correct the damage, trust their opinion but get references and consult with two or three reputable companies.
