The Disadvantages of Installing New Shingles Over Old Shingles
If you’re planning on installing a new roof or you’re repairing storm damage it’s likely that you want to upgrade your home exterior but you’d like to save money as well. If storm damage is the reason that you’re upgrading your roof, it’s likely that you’re looking to save as much money with the repairs as well.. A contractor may try to quote you on a roof replacement by installing new materials over top of the old and worn-out materials on your roof. Here are some of the largest disadvantages that you can experience by installing new shingles over old shingles!
You Could Lose Your Manufacturer’s Warranty
By installing new shingles on top of the old ones it is possible that you could lose out on your manufacturer’s warranty for the new shingles that you’re installing. If you want to make sure that you will qualify for a manufacturer’s warranty during your installation, make sure that you are installing only new shingles on a clear group.
Shingles Will Be Less Durable
Shingles installed in a second layer will often be less durable because they take longer to cool down and can become brittle or rot. Layering shingles does not result in increased durability, it actually works to reduce the material’s resistance against the elements over time!
Your Home Can Grow Over Insulated
Installing two layers of shingles will often make a home much too warm or lead to the chance that it will be difficult to regulate the temperature inside your home throughout the winter months. Having an over-insulted home in Florida can lead to a plethora of problems, but the worst has to be energy efficiency. The cost to run A/C in the average Florida home or business is already well above average, making your property even hotter will cause your already high energy bill to skyrocket further.
Shingles can adhere together: when shingles do this they offer less support and or can even be friction generated on runoff which can put your roof at risk for rot and storm damage.
Installing new shingles over old shingles is never a good idea, it results in less durable roof, a higher energy bill, and even void warranties!
