Having a leaky roof is never a good sign. There are many reasons why this can happen, but it is the last thing you want to deal with when it gets worse. When the rainy season begins, the repair is so much more difficult to repair. Not to mention the conditions that would prevent a roof repair company from coming out in stormy weather …
The problem with roof leaks is a bit difficult because you don't always see where the leak comes from. You will sometimes find that your blanket is discolored or stained with water. It may not appear as easy if you also use latex-based paints. An actual leak is only recognized when drops form.
This is also dangerous because water can rot wood in your ceiling. Losing an entire section break is a terrible thought, but it takes years. Especially if your house is over 60-70 years old, it will be a shame that it was not repaired earlier. Older houses with the old style of wooden lathes and plaster covers can collapse in large sections. And fixing that is not an easy task. It is therefore a good idea to have your roof checked regularly. Certain signs indicate where to look and what things should be updated. Here's a good example of what to look for: https://www.estrellaroofing.com/news/roof-leak/
Even if a roof has new shingles, the power of the sun is no match for modern materials. Shingles that use asphalt were incredibly popular in the 70s and 80s, but they dry out and crack. Just like streets paved with asphalt, they get hot and crack. However, this is not the only reason as your house is made of wood. It expands and shrinks when the heat of the day subsides. Connecting areas on your roof is most sensitive to this expansion and contraction process. Sloping areas of the roof where corners connect are also at risk. Even if skylights are installed, leaks can occur if they are poorly installed.
It's not so common for vents to leak out on the roof, but the natural buildup of your home and weather elements wear away the sealants with which they're glued. There is also the problem of events that can cause your roof to leak due to earthquakes or high winds from a hurricane that is going through. This can make your house wiggle like jelly and small cracks can form on the roof that you don't see immediately. An inspection is therefore a good idea, especially if you know what to look for. If you don't, it's best to call a professional. But a good eye standing on a roof ladder is perfect for seeing the condition as it is.
You can choose to repair roof leaks yourself using DIY tricks, or call someone to have the roof repaired for you. In the end, if you can do it yourself, you could save a few dollars. However, if you miss something, it can result in more roof leaks than you wanted.
