How to Tell if You Need a New Roof

The roof over your head is important and as such, it needs to be in the best shape come rain or shine. If it is, you can sleep comfortably knowing that your household and everything therein is safe. With that said, there are a few telltale signs that you need a new roof. Today, we’re taking a closer look so you can make an informed decision whether or not it’s time to consider updating your roof.

1. The Roof has Aged

If it’s been 20 years already and probably more, then it’s time for a roof change. You can easily determine it’s time to if you’ve been living in your home for that long, but if you haven’t, you can watch out if houses around you are changing their roofs. Give or take, they must have been around as long as your home.

2. Sunlight Penetrates through the Roof

Another warning sign that you need a new roof is if sunlight penetrates through it. You can determine this by climbing under the eaves in your attic and if there are beams of light, then it calls for immediate action. Think of it this way, if light can penetrate, chances that cold air, snow, and rain can do the same is high.

Now if it’s all good, you may want to check the underside of your roof if there are dark spots on it. It would mean the roof is already leaking and moisture has begun to accumulate in it. If the leak is small, then patching can easily resolve this, but if there are leaks in multiple regions, then you need a new roof. Keep in mind that larger leaks will also impact on the roof’s strength which could tell on its durability.

3. Curling of the Shingles

One of the most noticeable signs that you need new roof shingles is when it cups or crawls which is referred to as curling. A roof is said to curl when the edges of the shingles curve upward to form a cup-like shape. On the other hand, crawling is when the edges remain flat while the middle comes up. If either case is evident in your roof, then it’s time for a change since it’s only a matter of time before it starts to leak.

How much time do you have? Let’s say around five years give or take, however, it’s better changed sooner than later to wade off any potential mishap.

4. Shingles are Missing

Shingles can get replaced individually, but the only problem is, it may be difficult to find a shingle whose color is similar to the old one you are about to replace. This is because granule colors tend to differ over the years and the current shingle may have lost its color due to weathering. As a result, it ends up creating a problem of mismatched shingles and if you’ve changed a lot, you may be left with a roof that is comparable to a checkerboard and this screams, it’s time for a new roof replacement.

5. Cracked Shingles

If you notice cracked shingles on your roof, then you have the wind to blame for that. In this scenario, you only need to change a couple of shingles if the damage occurs in one particular area. However, if it is spread across different areas on the roof, then your house is in dire need of a roof change.

Whichever is the case, the real damage may come in three to five years time which is not much considering how much time flies and the high tendency to procrastinate.

6. Algae and Moss on shingles:

Some shingles are not algae or moss resistant and can provide a place to live for algae and moss. This will negatively impact the appearance and health of your roof over time. It could get worse if you try scraping or power washing the algae off since it could potentially remove the granules as well. If that happens, then you may have well rendered the shingles useless which calls for a need to replace the roof. Nonetheless, a possible solution that will preserve your roof and eliminate the algae is a combination of bleach and water to wash off the algae.

7. Sagging Roof

A sagging roof is something that should be given utmost consideration since it indicates an issue in structure. The roof in itself may not be bad, but the decking in the attic or foundation supports may have led to its sagging.

You can easily spot this out by using a stick to gently prod the sagging looking area. If it feels soft and tends to bend as you move the broom, then there has been moisture damage to your roof. While this calls for caution, it does not entirely scream danger even though attention has to be paid to it. Not waiting for it to progress to a complicated stage and in other regions of the roof makes it easier to tackle. Nonetheless, if depression has already occurred, then your best bet would be to contact an expert to work on it.

8. Paint Damage

Is the paint on your roof peeling or blistering, then it can be pinpointed to the accumulation of water beneath it. Asides from the loss in color, you may also notice a swelling in the woodwork. These blemishes can be attributed to a faulty roof that is in need of repair.
