Replacing An Old Roof? 3 Things To Consider

Posted on

If you have an older home, it may be time to replace the roof. Even if it appears to be in good shape, there can be a few underlying issues that may not be obvious. The average lifespan of an asphalt shingle roof is around 20 to 40 years while metal and tile roofs can last more than 50 years. If the roof is older than it's average lifespan, it's likely time for a replacement. Here are three things to consider when replacing an old roof.

Cost

When it comes to replacing an old roof, cost is something that can vary a lot depending on the type of roof being installed and the size of the home. Certain materials, such as copper and slate, are going to be far more expensive to replace. A slate roof for a 2,000 square foot home will cost on average between $17,000 to $84,000 while a copper roof of the same size will run anywhere from $25,500 to $39,600. An asphalt shingle roof costs between $1,700 and $8,400. When replacing an old roof, it's a good time to decide which roofing material works best with the budget. Some homeowners may find that replacing their old roof with a new roof of the same material may not be the most cost effective option.

Roof Decking

When it comes to residential roofing, there is more than meets the eye. Many homeowners think that a roof replacement involves only replacing the shingles. However, roof replacement also may involve replacing damaged roof decking, flashing, gutters, and repairing any other damage that may be present. Adding new decking alone can add around $5,000 to the cost of a roof replacement. Leaving room in the budget for repair or replacement of the structure underneath the roof is important.

Energy Efficiency

Replacing an old roof is a great opportunity for assessing the energy efficiency of the home. A few changes to the roof can make the home more energy efficient and decrease power bills. This is a great time to look into options such as cool roof coatings, solar panels, increased insulation in the attic, and energy efficient roofing materials. Many homeowners are surprised to find how much more energy efficient their new roofing is compared to their old roof. The energy savings can also help offset the cost of the new roof over time.

Replacing an old residential roof is something that many homeowners find themselves needing to do. When replacing an old roof it's important to consider the cost and which roofing option works best with the budget. What's underneath the roof is also important. It may be necessary to replace the roof decking that's currently in place. Roof replacement is also a great time to assess whether or not it's possible to make the roof more energy efficient.
