Shingle roofs can have a life span of up to 30 years, however some may not quite reach that age because of many factors. First, there is the quality of the shingle itself. Some are only rated for 20 years, and depending on the level of wear and tear, that number may never be reached. There are things you can do to extend the life of your roof. For instance, trimming tree limbs off of your roof. Tree limbs move in the wind. Even a light gust will move the limbs enough to sweep away the granules little by little.
Mother nature and/ or neglect will do so much damage to a roof, it is hard to say which one is worse. We can’t control or predict nature, but we do have control of the things we do. If you live under tree canopies, the shade will save you a fortune in electricity, and the extra wear on your A/C. But your roof will need to be kept clean, unless you want to replace it prematurely.
When a roof has reached its lifespan, you will know from the leaks on the inside of the building. Leaks become areas of dampness, and when that humidity and hot air mix, they create the perfect environment for mold. Mold will make you sick and is also another added expense to the repair. The best time to replace the roof is prior to noticing leaks.
Upon inspection, it was very obvious that a repair would be pointless and also not ethical to even offer as an alternative.
When Shingles tear off like this, it has been in the works for a while. For them to just tear off, the wind has folded them back and then flat many times. When shingles reach the end of their lifespan, they become brittle and will eventually tear off…or rather just break off.
