How do you know it’s time to replace your roof?

We get a lot of questions about roofing, the best materials, whether skylights are a good idea, the best way to keep them clean, and so on. But the question we get more than any other is “How can I tell if I need a new roof.” It’s also one of the most important questions you can ask because your roof is the first line of defense against the elements for your home.

If there’s an issue with your roof, it could take months (or even longer!) before you know for sure. That’s why it’s a good idea to inspect your roof once or twice a year to make sure it’s in good shape, or at least hire a professional roofing contractor like Spruce Up Northwest to look it over for you.

Some signs may not be that obvious with just a cursory overview, but there are a few things that should set off alarms when you see them. This goes beyond a tree branch falling on the home during a storm or other clear problems. Those are immediate concerns–we’ll discuss the slow-moving issues that may cause even more damage.

What are 5 Signs You Need a New Roof

There are a few things that make it pretty apparent you need a new roof but unfortunately, these issues may have been brewing for a while. If you notice any of these problems, a deeper investigation is needed:

  1. Age 
  2. Water Damage
  3. Damaged Shingles
  4. Sagging Roof Deck
  5. Moss/Algae Growth

Age of the Roof

First, consider the age of your roof. Depending on the roofing materials, your roof can last anywhere from 15 years to more than a century. Asphalt shingles are the most common roofing material because they are relatively affordable and come in a variety of styles and colors. On average, asphalt shingles can last between 15 to 30 years.

Wood shingles last a little bit longer, between 20 and 25 years, and composite roofing will last a little bit longer than that. Clay tiles can approach 50 year lifespan while there are metal and slate roofs that have been around longer than 100 years. All of this depends on proper installation, service, and maintenance.

If your roof is starting to approach the end of its lifespan, it may be time to start thinking about a replacement. Give Spruce Up Northwest a call for a free inspection of your roof. We can see if it needs spot repairs or if it’s time for a complete tear down.

Water Damage

If you notice water stains on your ceiling or walls, it could mean that you have a leaky roof. When water seeps through the roof, it can drip down onto your ceilings and walls. Over time, this moisture can cause unsightly stains and discoloration, damaging the paint, plaster, drywall, and more.

Water that penetrates through the roof can also soak into the structural components of your home. Continued exposure to moisture can weaken the joists and framing of your home, compromising the structural integrity. In many cases, this damage isn’t readily apparent until it’s too late or you have regular inspections.

When you go into the attic, do you notice mold and mildew? This is a big warning sign that your roof is leaking and can actually be harmful to the health of you and your family. Mold spores can spread quickly and thrive in damp, dark areas, causing respiratory problems and allergic reactions.

Missing or Damaged Shingles

Missing or damaged shingles can be clear indicators that your roof may need to be replaced. Shingles protect your home against the elements, including rain, wind, snow, and sunlight. When they are missing or damaged, they leave your roof vulnerable to water leaks and other weather-related damage.

Also, as asphalt shingles age, they naturally shed granules due to exposure to sunlight, weather, and foot traffic. However, excessive granule loss can occur prematurely due to factors such as poor shingle quality, poor installation, or severe weather conditions. If granule loss is obvious on your roof, you’ll definitely want to consider a new roof.

The longer you wait to inspect missing or damaged shingles, shakes, tiles, and other roofing materials, or general roof damage, the longer water could be seeping into your home. Even a handful of missing shingles can cause major headaches for you and your home. And, let’s face it: it’s not a very good look, either.

Sagging Roof

If you notice your roof sagging in certain areas, this is a huge red flag, especially if it’s noticeable enough to see from the ground. It’s essential to address roof sagging promptly to prevent further structural damage and potential safety hazards.

There are a few reasons this could be happening. This damage may be due to issues such as rot, decay, termite infestation, poor craftsmanship, or age. While damaged roofing may be the cause, your home will need more than new shingles. There are structural issues that will need to be fixed, including the trusses, roof decking, ceiling joists, and so on. 

If these problems aren’t taken care of immediately, heavy snowfall, ice, or anything that adds extra weight could cause that part of the roof to collapse. And then you’re dealing with many other issues, including possible injury to you or your family.


While moss and algae growth alone may not indicate the need for a new roof, they can trap moisture and accelerate the deterioration of your shingles. If you notice significant moss or algae growth, it’s a good idea to have your roof inspected by a professional.

It could just be a matter of cleaning the roof, especially if it still has plenty of good years left. But the moss could also be hiding damage that needs to be remedied.
