Roof Replacement: The Differences Between Overlay And Tear-Off Installations
A big question that everyone asks when replacing a roof is what type of installation you are going to use. If you only have one layer of roofing material on the roof, you have the option of overlaying new material on top of the old material. You can also rip off all the old roofing material and start from scratch. Both methods have their own advantages, which is why it helps to know more about them.
The main reason for picking an overlay roof instead of a tear-off roof is due to your budget. As you may assume, an overlay roof is going to be much cheaper because you are not removing the old roofing materials. You are not paying for the labor to have the old material removed, the disposal of that material, and the installation of all the underlying material that will be removed as well. However, that doesn't mean an overlay roof is going to save you money in the long run.
If you need a new roof, something must be wrong with your old roof that is requiring this expensive repair to be done. For example, if the old roof was leaking, it is possible that you have water damage underneath the old roofing material. If you overlay a new roof on top of the existing roofing material, you won't be able to repair all of the damage that was caused by the old roof that is damaged.
A tear-off roof gives you the advantage of being able to inspect everything that was wrong with the old roof and make necessary repairs to the supporting structure. You'll be able to remove and replace any underlayment material that is rotting, make repairs to your roof deck, fix parts of your roof that are warped, and repair damage caused by pests.
Home Value Factors
One thing to be aware of is that homebuyers do consider the shape that your roof is in when they purchase a home. Having a tear-off installation is going to be looked highly upon, while an overlay roof may be a reason that some people walk away from a home. Consider how long you will be staying in the home because any plans to sell could result in your home losing value due to an overlay roof.
