11 Reasons Why It's Not a Good Idea to Install a New Roof Over an Existing One
Thinking about putting a new roof over your old one?
It might seem like a quick fix, but it can actually cause more problems than it solves. This article will explain why installing a new roof over an old one is a bad idea. Read on to learn the top reasons and how they affect you.
By the end, you'll understand why calling a professional roofing company like Pineapple Express Roofing is the best course of action.
1. Extra Weight Can Damage Your House
Putting a new roof on top of an old one adds a lot of weight.
Roofs are heavy. When you add another layer, it can be too much for your house to handle. The structure of your house might not be strong enough. This can cause cracks in the walls and ceiling. In the worst cases, your roof could collapse. It's better to remove the old roof first.
This keeps your house safe and strong.
2. Hidden Damage Can Get Worse
When you cover the old roof, you hide any problems it might have.
These problems can include leaks, rotting wood, or mold. You might not know about these issues until they get worse. By then, the damage can be expensive to fix. Removing the old roof lets you see and fix these problems.
This makes your new roof last longer and keeps your home in good shape.
3. Shorter Lifespan for Your New Roof
A new roof needs a good base to last a long time.
Putting it on top of an old roof doesn't give it that. The old roof might have weak spots or damage that affects the new one. This can make the new roof wear out faster. You might have to replace it sooner than expected.
To get the most out of your new roof, start with a clean, solid surface.
4. It Can Void Your Warranty
Many roofing companies offer warranties for new roofs.
These warranties protect you if something goes wrong, but, if you install a new roof over an old one, the warranty might not be valid. The roofing company can say that the old roof caused the problem. This means if something goes wrong, you have to pay for it yourself.
Always check the warranty rules before deciding.
5. It Can Be Against Building Codes
In many places, it’s against the rules to put a new roof over an old one.
Local building codes often require you to remove the old roof first. If you don’t, you could get in trouble with the city. You might have to pay fines or remove the roof. Before you start, check your local building codes.
This saves you from legal problems and extra costs.
6. Higher Energy Bills
Roofs help keep your home warm in winter and cool in summer.
When you put a new roof over an old one, it can trap heat. This makes your home hotter in the summer. Your air conditioner has to work harder to cool your house, leading to higher energy bills. Removing the old roof first can help your new roof work better.
This keeps your home comfortable and saves money.
7. Poor Appearance
A new roof should make your house look better, but when you put it over an old roof, it can look uneven.
The new paint might look nice at first, but soon the old paint texture will show through. This can make your new roof look bumpy and messy.
For a clean, smooth look, always remove the old roof first before a new installation.
8. Difficulty Selling Your House
When you sell your house, buyers will inspect it carefully.
They will notice if you put a new roof over an old one. This can make them worry about hidden problems. It can also lower the value of your house. Buyers might offer less money or walk away. To make selling easier, do the job right by starting with a fresh roof.
Buyers know it’s not the best way to install a roof.
9. Fire Hazards
Old roofs can be made of materials that catch fire easily.
When you cover them with a new roof, you can create a fire hazard. The old materials can still catch fire and cause the whole roof to burn.
Removing the old roof reduces this risk and makes your home safer.
10. Costly Repairs in the Long Run
It might seem cheaper to put a new roof over an old one.
On the contrary, this can lead to more problems and higher costs later. Hidden damage, poor insulation, and a shorter lifespan mean you might spend more on repairs. Starting with a new, clean roof can save you money over time.
It ensures your roof works well and lasts longer.
11. Harder to Inspect and Repair
When you have two roofs, it’s harder to check for problems.
Roofers can’t see the old roof easily. They might miss leaks or weak spots. Fixing these problems later can be more expensive. It’s like trying to find a leak in a waterbed with a blanket on top.
You can’t see where the water is coming from.
