Roof replacement is an expensive process, but it is one that you cannot ignore, as the roof plays an integral role in your home’s security. To avoid the high costs associated with replacements, many homeowners in Oklahoma decide to install new roof shingles without removing the old ones.
Are you thinking of doing the same to save your time and money? The idea of a quick fix, especially when it comes to something as crucial (and expensive) as a roof, can be tempting. But is this a good idea in the long run? The answer to it is a bit complicated, but don’t worry, because in this blog post, we’ll explore the answer to this question in detail so that you’re able to make the best decision for your roofing system.
The Short Answer: Yes, But…
Technically, yes, you can put new shingles over old ones. It’s called a “roof overlay” or “re-roofing,” and it’s a practice that’s been around for a while. In some cases, it makes sense to go this route, but roofing professionals don’t tend to offer this service since it’s not always the best option.
There are a lot of factors to consider, and while an overlay might save you some money upfront, it could end up costing you more down the line if things don’t go as planned.
We’ll walk through the pros, cons, and situations where a roof overlay might work, and when it’s best to strip everything down and start fresh.
Why Homeowners Consider Putting New Roof Shingles Over Old Roofs
1. Lower Upfront Costs
Since you’re skipping the labor and disposal costs associated with tearing off the old roofing material that’s typically done during a replacement, re-roofing is generally more affordable. If you’re on a tight budget and your roof doesn’t have any major underlying issues, this could be a good option for you.
2. Less Time-Consuming
Overlaying shingles is a quicker process since there’s less prep work involved. If you’re dealing with a time-sensitive situation, like an approaching rainy season, re-roofing can be a way to get things done in a hurry.
3. Temporary Solution
If you’re planning to sell your home soon, you might opt for a roof overlay to improve its appearance without going through the full expense of a new roof. It’s not a permanent fix, but it can give your home a facelift that might appeal to buyers in the short term.
What Do The Oklahoma Building Codes Say?
If you’re considering this roofing method it’s always best to check your local building codes to ensure that it’s legally permitted in your region. In some places, building codes limit the number of shingle layers you can have on your roof. Most areas allow two layers, but there are places where only one layer is permitted. Unfortunately, Oklahoma is one of these places. In Oklahoma, local building codes don’t allow homeowners to simply install a new layer of asphalt shingles on top of old ones.
More layers aren’t necessarily better. In fact, adding more than two layers of shingles is generally not recommended because it puts too much strain on the structure of your house.
So, before you decide to overlay old shingles with new ones, check your local building codes to make sure you’re not violating any regulations. A good roofing contractor will also be familiar with these codes and can guide you in the right direction.
Why Does Oklahoma Have This Rule?
Now, let’s talk about why Oklahoma doesn’t allow you to layer new shingles over old ones. Since the state is known for its unpredictable weather such as tornadoes, hail, and heavy rain, your roof needs to be in good shape to withstand the elements.
Re-roofing simply hides problems without treating any underlying issues. This means that old problems will still persist, even with the new shingles, leaving your roof just as vulnerable as it was before. For instance, if your old shingles are curling or showing signs of wear, it’s better to deal with them as soon as possible. These curled shingles may even create an uneven surface and gaps when the new shingles are installed over the top.
Why Is Installing New Shingles Over Existing Shingles Such A Bad Idea?
As we covered in the previous section, the Oklahoma building code does not allow you to install multiple layers of shingles on your roof, and you’ll run into legal issues if you try to do this. Building codes are there for a reason, and ignoring them can lead to fines or complications when selling your home.
But this is not the only reason you should avoid re-roofing. Here are some other problems that can occur:
Weight Issues:
Adding another layer of shingles increases the weight your roof needs to support, which can lead to structural issues. Over time, this added weight can stress the rafters and framing of your home, potentially leading to costly repairs.
Potential for Leaks:
If the old shingles are damaged, layering new shingles won’t solve the underlying problems. You might end up with leaks or water damage later, which could not only damage your roof but also lead to mold growth and structural problems inside your home. Addressing these issues upfront is key to maintaining a dry and safe environment.
Limited Lifespan:
The lifespan of the new shingles may be reduced since they’re sitting on a potentially deteriorating foundation. The original shingles can trap moisture, which accelerates wear and tear on the new layer. This means you could find yourself facing costly repairs or replacements sooner than expected.
What Should You Do Instead?
If layering isn’t allowed and you’re facing roofing problems, don’t worry! Here’s a straightforward game plan:
Get an Inspection: Start with a professional inspection. A qualified roofer can identify any issues with your current shingles and determine if a replacement is needed.
Full Roof Replacement: If your roof is past its prime, a full tear-off might be necessary. While it sounds like a big job, it ensures your new roof has a solid, reliable foundation. This is crucial for long-term protection.
Choose Quality Materials: If you’re going for a full replacement, invest in high-quality shingles. It might cost more upfront, but it can save you money in repairs down the line.
Final Thoughts
So, can you put new roof shingles over old ones? In Oklahoma, the answer is a definitive no. While it might seem like an easy solution, following local building codes is crucial for your home’s safety and longevity.
