Different factors affect how long a roof lasts. Sun exposure gradually takes its toll over the years, and even if you keep up with maintenance, your roof will need to be replaced eventually. You might even need to replace a fairly new roof when it's been badly damaged. It's always good to check your roof occasionally and have it inspected if you think it could be leaking. Replacing the roof in a timely manner keeps your home from being water damaged. Here are times a roofing contractor may decide your home needs a new roof.

When There's Widespread Damage From Hail Strikes

Hail is damaging to asphalt roofs. A hail strike can crack the shingle and leave behind a dent or bruise. If there are many of these marks on your roof, then the roofer may recommend that the roof be replaced because the dented areas could start leaking, even if the roof is new.

When Many Shingles Are Bald

A loss of granules on the shingles is a sign of old age. When your roof has shed a lot of granules, it loses protection from UV rays, and it ages even quicker. The solution for granule loss is to replace the roof. Granules slowly fall off or get blown off as the roof ages, and when your roof is old, the loss of granules makes it look worn out. A new roof will make your home look more attractive again too.

 When The Deck Is Rotted

The asphalt shingles attach to sheets of plywood, or the deck. If the deck gets wet, it starts to rot. This makes the plywood feel soft when you walk on it. One of the things the roofing contractor checks for is the sturdiness of the deck. If it has water damage, it has to be replaced. If the rotted area is confined to a small part of the roof, repairs might be possible by cutting out the bad plywood, replacing it with new material and then adding new shingles. If a large part of the deck has to be replaced, then it's time to decide if you want a whole new roof since a large portion of the shingles will be off anyway.

Once the roofing contractor has examined the roof, they can help you decide on the need for a new roof versus repairs. Many roof problems, such as animal chew holes, loose flashing, and damaged shingles can be repaired, but when the problem covers the majority of your roof, replacement may be a better option.
