How Much Does it Cost to Replace a Roof?

When considering the cost to replace a roof there are usually a few reasons to contemplate this. It may simply be time for you to replace your roof or you may want a new look for it during a remodeling phase. In some cases, you may be preparing to sell your home and want to replace it or are looking to buy a home that will certainly need a new roof. Whatever the case may be there are a few ways to determine your expenses.

Here are some of the factors that go into coming up with an estimate to replace your roof:

  • The materials
  • Whether you hire a professional or do it yourself
  • The amount of repair work needed
  • The location of the home
  • The slope ¬†or pitch of the roof

There are other details that can go into the cost of replacing your roof, but these are some of the major factors. For example, if you are simply replacing the shingles and intend to do it yourself the cost will obviously be much less than having a professional put on a whole new roof and making repairs along the way as well.

Little Details

One thing people often forget to consider when it comes time to replace a roof is all of the factors that could have caused previous damage. You may be hoping to merely reshingle or just replace part of your roof. You may even be building your new dream home and are just trying to determine how much the roof part of the construction may cost. It is important to take into account all of the things that could have caused damage or may cause future damage and will impact roof replacement costs.

  • Weather conditions – While obviously unavoidable, this is what causes the most damage to a roof. It can be over time or in a single bad storm. The sun for instance, and UV rays cause the deterioration process to happen much more rapidly. Rain, especially when accompanied by wind, can get underneath the shingles and cause serious damage. Excess moisture and even worse leaks can cause mold, mildew rot and other problems to damage to roof and create the need for repairs. Snow and ice also cause the same type of problems and can take their toll on your roof especially if you live somewhere that has severe winter storms.
  • Moss, mold, algae and condensation – Many of these start as small problems that develop into much greater ones. Moss for instance can take hold and spread rapidly. The end result is that this can cause serious rot problems. Condensation can create this problem or add to it. Ventilation can help prevent this. All of these are things you may need to think about prior to getting your roof put on or replaced.
  • Flashing or shingle deterioration – Both of these are meant to help protect your roof. If you have damage or deterioration to your shingles or flashing it means your roof may begin to weather, weaken or otherwise deteriorate quicker. Checking your shingles and flashing periodically is a great way to make repairs prior to having to replace your roof all together.

Picking Your Roof

Aside from labor costs, your materials are generally the most expensive detail of replacing your roof. Of course, your cost also depends on how much repair is involved. In many cases, you may not need repair. Unfortunately for some homeowners, what lies beneath those old shingles is where the majority of your problems and expense come into consideration.

Here are some of the most common choices for roofing:

  • Shingles – The lowest cost material you can get for residential roofing aside from a tin roof would be the asphalt shingles. In fact in between replacing your roof you can often replace or repair shingles yourself to help prolong the life of your roof. There are also various types of wood shingles and shakes that make popular and affordable materials for your roof.
  • Tile – This style is slightly more expensive but offers better protection and is generally quite durable. The problem with tiles is that if any of them do break they need to be replaced. The most common style you see is the Spanish tile for the clay, rounded tile look so popular in the Southwest and in the state of Florida. This is partially due to the fact that this material works well to absorb heat.
  • Slate – For the most expensive material around, slate would be your choice. Aside from having a desirable and attractive look, slate is used because it is close to being indestructible. Many older homes that have withstood the test of time still have the old slate roofs. These roofs remain a great option for those who want a durable material and a classic look.

Some of the decision making process may be determined by some details about your home, location as well as your budget. For example, Florida homes are more likely to have the tile roof due to year round heat. Many Northeast homes have slate to withstand more extreme winters and the likelihood of storm damage. So consider these details when deciding on your roofing materials:

  • The location of your home has a lot to do with this. As just mentioned the climate and weather play a large role in which type of material may work the best for your home. This can be based on weather or likelihood of certain types of storms.
  • The location of your home on your property. If you are on a steep hill or have a large number of trees near the roof this can impact the material you should use and the expense involved with professional replacement.
  • The slope or pitch of your roof can make the project more expensive if it is severe. In cases like this you should only allow a professional to do the work.

Once you decide on the material and factor this for the size of your roof, this should give you your estimate of how much it will cost to replace your roof.
