When it comes to replacing a roof, homeowners are often faced with the decision of whether to strip the old roof entirely or to simply add a new layer on top. While it may appear easier and cheaper to go over the existing roof, stripping the old roof and starting anew has many advantages that make it the superior choice.

Here are five reasons why stripping a roof is better than going over with a new layer:

1. Better Inspection: When you strip a roof, you can inspect the underlying structure, such as the roof deck, and identify any hidden issues that may have gone unnoticed. This inspection can help you fix any problems before they become bigger issues. When you simply go over with a new layer, you are just covering up any existing issues, which can lead to bigger problems later on.

2. Increased Lifespan: Adding a new layer of shingles can add weight to the roof, causing stress on the existing structure. When you strip the old roof and install a new one, you are starting fresh and can ensure the new roof is properly installed. This can increase the lifespan of your roof and potentially save you money in the long run.

3. Better Appearance: Stripping a roof allows you to completely change the look of your home’s exterior. You can choose from a variety of new shingles that match your home’s style and enhance its curb appeal. Going over with a new layer of shingles may not provide the same level of aesthetic improvement.

4. Prevent Moisture Buildup: A new layer of shingles over an old roof can trap moisture between the layers. This can lead to mold and mildew growth, causing potential health hazards and structural damage to your home. Stripping the old roof allows for proper ventilation and insulation, preventing moisture buildup.

5. Avoid Potential Problems: Adding a new layer on top of an old roof can create potential problems. For example, if the old roof was damaged or leaking, these problems could persist with the new layer. Additionally, if the existing shingles are not flat, the new layer may not lay flat, which can lead to air pockets and potential leaks.

In conclusion, while it may appear more convenient and cost-effective to simply add a new layer of shingles on top of an old roof, stripping the roof and starting fresh has many advantages. By doing so, you can ensure a proper inspection, increase the lifespan of your roof, improve the appearance of your home, prevent moisture buildup, and avoid potential problems down the line. So, if you’re considering a new roof, it’s worth taking the extra step to strip the old one and start fresh.
