How to Know When Your Roof Needs Replacing

How to Know When Your Roof Needs Replacing

If you have a big downpour and notice moisture in your ceiling, you may be wondering whether this is a sign that your roof needs replacing.

In some cases, it could be a freak event, and the nature of the rainfall and the direction it came down in overwhelmed your roof plumbing. In that case, it may not suggest the need for a new roof. But in some cases, it could be a sign of a new roof being needed. Consider contacting this roof repair company for professional assessment and assistance.

In this article, we outline the clear signs that you should look out for, that do suggest your roof may be in need of repair or replacement.

In all cases, we also recommend speaking with a professional roofing company, like Magnum Roofing, as you consider the available options.

1. Loose shingles

Shingles are a great way to keep your roof protected against water damage. However, if you notice any loose shingles on your roof, this could mean an issue with the adhesive holding them in place. This can lead to leaks and even more serious issues, such as mold growth. It’s best to get these problems fixed before they become bigger problems.

2. Cracked granules

If you see cracks in the granules on your roof, this may indicate that the underlying membrane has been damaged by wind or hail. The granular layer protects the membrane beneath it, so if it gets cracked, it will weaken the entire roof structure. Besides, granular cracking means the roof needs to be replaced sooner rather than later. You should have your roof inspected by a professional to determine what needs to be done about this problem.

3. Dark spots on the roof

Many different things can cause dark spots on your roof. They can indicate a leaky roof but can also be caused by algae growing on the roof’s surface. Either way, dark spots need to be addressed immediately because they can cause rot and mold to grow underneath the spot.

Dark spots can also be caused by tree branches falling onto your roof. For this to happen, the branch must break off the tree, fall onto your roof, and remain there for a while. If you find many of these spots on your roof, you likely need to replace your roof.

4. Water damage to lower floors

Water damage can also be a sign that your roof needs replacing. If you notice water damage to the lower floors of your house, this could mean that the roof is leaking. If you notice water stains on the ceiling, this could mean that water has gotten into the attic through the chimney flue. If you notice water marks on the walls, this could mean that rainwater has seeped into the interior of your home. These are all signs that your roof needs replacing, so contact a professional roofer immediately like central PA roofers.

5. Constant leaks and drips

If you’re noticing constant leaks and drips from your roof, it could signify that your roof needs replacing. Even if there aren’t any cracks in the granule layer or other obvious signs of damage, some roofs need to be replaced simply because they’re old. Older roofs need more repairs and don’t last as long as newer ones do. In these cases, it makes sense just to bite the bullet and invest in a new one. Sometimes, however, leaks are due to poor installation. That said, even poor installations should be checked out as soon as possible because they can worsen over time. A good rule of thumb is to call a professional contractor if you notice any unusual dripping sound or even tiny puddles accumulating near your home.

6. Moss or algae growth

Moss and algae can also be another sign that your roof needs replacing. This typically happens when the moss or algae spores land on the roof surface and start growing. Moss tends to grow between the joints where roof sections meet, preventing air circulation and increasing moisture levels within those areas. Algae thrive in moist environments, including moist sections of your roof (such as near gutters). Regardless of what type of moss or algae is growing on your roof, both pose significant health risks for humans and animals. They promote the growth of bacteria, viruses, and fungi that can harm you and your family. Plus, moss and algae remove oxygen from the atmosphere, which is bad for the environment and can lead to problems with your roof. Make sure to clean up any moss or algae on your roof before it becomes a bigger problem.

7. Storm damage

Another sign that a new roof is needed is when you experience different types of roof storm damage . If a large object has landed on your roof—like a fallen tree or if you’ve experienced lightning strike damage, ice storms, tornadoes, or even derecho storms—then it’s time to assess whether your roof can be repaired or if it needs to be replaced completely. You might also need to replace the entire roof after experiencing wind and hail damage.


Leaving a damaged roof untreated for a long period of time could turn a small problem into a big one, so if you notice significant leaking or any of the other symptoms described above, speak to your local roof plumber about coming to inspect your house as soon as possible.
