Types of Roof Damage

A study conducted in 2016 found that roof repairs cost more than $690 on average.  The same study found that roof replacements cost more than $7,000.  These numbers make it pretty obvious that preventing damage to your roof is the best course of action.

Here is a list of the things that you will want to be aware of when you are checking your roof for signs of damage.


There are many portions of your roof that can fail.  The most typical culprits are the flashing of your roof and the shingles themselves. The flashing on your roof is the material that connects the chimney, vents and skylights to the roof itself.

It also connects the chimney to the roof.  Flashing is only good for ten years and will often need to be replaced when it has reached this age. If the flashing appears to have deteriorated, cracked or corroded, or if the gaskets around the vents are showing wear, the flashing will need to be replaced.

Flashing runs about fifty dollars a roll so it is significantly less expensive than the cost to replace the whole roof.

The shingles on your roof can be made from various materials.  No matter what material your shingles are made from, you will want to be sure that they are not cracked, abraded or missing in places.  Shingles cost about thirty dollars a bundle, which is much less expensive than replacing the roof itself.


There are various animals that can cause significant damage to your roof.  Squirrels and rats can nest in your insulation, or under your shingles.  They will tunnel in the insulation and can cause major damage by leaving excrement behind.

Raccoons and birds can be guilty of causing the same type of damage.  The attic is the best place to look for damage due to animals.

If animals have moved in to your attic and your roof, you will likely have to hire a specialist to remove them and to seal any entry points they were using to enter the house.  A minimal animal removal will cost around $500.

Wind and Tree Damage

While the sound of trees rustling in the breeze can be peaceful, it can also be the source of damage to your shingles.  Tree branches can crack tiles and shingles or even knock them off the roof altogether.

Ideally, tree branches need to be kept at least ten feet away from your home and its roof.  After a storm, you will want to make sure that your roof doesn’t have any cracked shingles, worn spots, broken fascia boards or loose metal sheeting.  Pruning your own trees is much less expensive than dealing with storm damage.


Moss is one of the biggest culprits behind major roof damage. Moss can invade the deeper layers of your roof and its spores can spread out across large sections of the roof, breeding more and more moss.

Moss is very good at storing moisture and the shingles can wick it up.  Once the shingles are soaked through, the deeper layers of the roof will get wet and rot can set in. Fortunately, moss is something that a homeowner can remove without the help of a professional.

Moss is fairly easy to remove and once the moss is gone, applying zinc or copper solution will kill the moss that is deeper in the layers of the roof.  Zinc or copper solution costs about $15.

Thankfully, if you do have to replace your roof, or segments of it, there are shingles that come with built-in moss inhibitors.
