Can You Put New Shingles Over Old Shingles?

Keep your roof in top shape with proper maintenance. It includes knowing the different ways to deal with various roofing problems. A common problem most homeowners face with their shingle roofing is how to replace missing or damaged shingles.

For instance, when dealing with old shingles, you may ask whether it’s okay to place new shingles over them. The answer to this is no. You shouldn’t place new shingles over old shingles, and here are some reasons why:

1. It will not look good.

New shingles should be placed flat on the roof and then nailed down. Old shingles have been on there for a long time, so any new shingles placed over them look bumpy or gap-filled. Since the shingles won’t be accurately mounted on the roof, you would have an uneven surface. It can make your home look unappealing and cause other issues such as leaks.

2. They won’t last very long.

When you nail one piece of shingle over another, you are essentially covering up the original material underneath. The wind and rain can quickly get under this new material and start causing damage. Professional roofers will also have difficulty inspecting your roof since it can hide signs of wear. Over time, these areas will begin to rot and eventually tear apart. It can cause you more costly and complex repairs in the future.

3. There isn’t enough support.

Placing new shingles over existing ones means that your roof can suffer from weight strain. If your roof has been around for a while, it likely has some weak spots that were never fixed. These spots can become even more fragile if newer materials have covered them. To avoid weight strain on your roof, you should avoid placing new shingles over old ones.

4. It can cause safety hazards.

Simply putting new shingles over an older roof can create a dangerous situation. For instance, water can seep through the gaps between the two shingles and into the attic space. It can lead to mold and moisture buildup, which can destroy the house’s insulation and drywall. In addition, mold and moisture buildup also severely threaten your family members’ health.

5. It will lower the value of your property.

Since shingles constitute a significant part of a home’s exterior, not taking steps to replace them properly will lower your property’s value. Potential buyers will notice the roof’s poor condition, especially if there are noticeable holes in the shingles. So, although replacing shingles can be expensive upfront, it saves money in the long run because it keeps your property looking great and increases its resale value.
