The roof is the most important aspect of a house; the roof over your head needs to be intact. It is a basic necessity. The obvious reasons to indicate that you need to change your roof are if the roof is leaking. The other early warnings are, if the roof is over twenty or twenty-five years, that it goes through its wear and tear, and you might notice some layers coming off; this is a reason to replace it. The material after being exposed to rain and sunlight for so long might become soft and chip off.
The shingles of the roof are a good indicator. You will notice that they are losing granules and have become smooth; this is when you know that they have come way past their life expectancy as they are defective. Sometimes the roof feels spongy and weak, and this is because they have weakened due to moisture, and this is one of the reasons why they should be replaced. If there is some moss growth on the roof, then this is also a sign that it has gone bad. It is important to keep a check on your roof from time to time and make sure it is made of high-quality materials. Visit here to know more about roof repair.
