Reasons to Avoid Installing a New Roof Over Your Old One

M & M Roofing Corp. is a roofing company that has been in the business for many years. We are experts in roof installation and can help you avoid installing a new roof over your old one, which may be pricier than you think.

Voided Warranty

A roof is a vital part of any building and it needs to be taken care of. If you install a new roof on top of your old one, then you are voiding the warranty and putting yourself at risk.

The first thing that you should do is to take your roof off. You don’t want to risk having it collapse on top of you or your loved ones. Clean up the debris that has accumulated over time and then get a new roof installed.

Added Weight

The weight of a new roof is often added on top of the old one. This may cause the roof to collapse, or cause leaks in the house.

Some people may think that installing a new roof over their old one will solve all their problems, but this is not always true. If there are any structural issues with your house, adding more weight to it will only make these issues worse.

Shortened Lifespan

The installation of a new roof over the old one can be an expensive alternative. It is not always necessary to install a new roof over the old one. The old roof can be repaired by using different techniques.

Inspection and Installation Mistakes

There are many mistakes that can happen during the installation of a roof. If a roof is not installed properly, it will leak and cause many other problems. It’s important to make sure that the roof is installed correctly and in accordance with building codes.

Some common mistakes include:

  • Not checking for any nails sticking out before installing a new roof

  • Failure to install flashing at the base of chimneys, skylights, and vent pipes

  • Failure to remove old shingles before installing new ones

  • Failure to install drip edge flashing around chimneys, skylights, vent pipes, dormers, and other protrusions


The conclusion is that it is not worth the cost and hassle to install a new roof over your old one. The reasons are that it will be pricier, take longer, and require more materials than you think.
