When it comes to roofing, many homeowners believe that the best way to fix a problem is to simply cover it up with more material. However, this is not always the case, especially when it comes to shingles. Installing new shingles over old ones can actually cause more damage and lead to bigger problems down the road. In this blog post, we will discuss why you should never install new shingles over old ones, and what you can do instead!
You May Void Your Roofing Warranty
One of the major reasons why you should never install new shingles over old ones is that it can actually void your roofing warranty. A lot of roofing companies will only warranty their products if they are installed according to the manufacturer’s instructions, which generally does not include installing new shingles over old ones. So, if you do end up having problems with your roof down the road, you may not be able to get any help from the manufacturer if you choose to go that route.
It’s Not a Permanent Solution
Another reason why you should never install new shingles over old ones is because it’s not a permanent solution. Sure, it might seem like a quick and easy fix, but odds are, it’s only going to last for so long. Eventually, the new shingles are going to start to show signs of wear and tear, and you’ll be right back where you started.
You’ll End Up Spending More in the Long Run
Installing new shingles over old ones might seem like a cheaper option upfront, but there’s a good chance that it’s going to end up costing you more in the long run. Not only will you have to buy new shingles, but you’ll also have to pay for labour to have them installed. And, as we mentioned before, it’s not a permanent solution, so you’ll likely have to do it again in a few years.
It Can Cause More Damage
Last but not least, installing new shingles over old ones can actually cause more damage. The weight of the new shingles can end up putting too much pressure on the old ones, causing them to crack or break. Additionally, the nails you need to use to install the new shingles can also damage the old ones. So, not only will you have to deal with a damaged roof, but you’ll also have to pay to have it repaired.
The Bottom Line
All in all, it’s just not worth the risk to install new shingles over old ones. It can void your warranty, it’s not a permanent solution, it’s more expensive in the long run, and it can actually cause more damage. If you’re having problems with your roof, the best thing to do is to consult with a professional roofing company. They’ll be able to assess the situation and recommend the best course of action. Now, you may find that their recommendations are a bit more expensive than simply installing new shingles over the ones, but they will almost certainly save you a lot of headaches in the long run.
