Why You Shouldn’t Install New Roof Shingles Over The Old

Roofing Boise Idaho


Replacing a roof is an expensive project, and it may be one that you were not planning to make at the moment. Understandably, you may be looking for ways to save money on this project, and the thought may have crossed your mind to simply lay new shingles over your existing ones. After all, tearing off the existing roofing components will take time and cost money. While this may seem like an excellent solution to save money on roof replacement, there are many reasons why this is not advisable, and will end up costing more in the long run.

Problems When You Replace Your Roof Later

Some homeowners who are interested in saving money by layering shingles may also choose to install cheaper shingles. Cheaper shingles may only have a life span of 15 years or less, which means you will have to pay for another replacement soon, usually before the 15 years is up. Also keep in mind that a third layer of shingles will not work at all (will not stay on the roof). Therefore, when you replace the roof later, you will have to pay more money to remove the two layers of shingles rather than just one layer. More than that, layering shingles could actually decrease your home’s value because inspectors know that layered shingles will cost the homeowner more money in the future. This could be brought up in their report.

When Bad Weather Strikes

Layered shingles are thicker overall, and this means that the nails may not work as well to keep the shingles in place. During strong winds and storms, the thicker nature of layered shingles makes them more likely to rip off. Both layers may rip off, or the underlying first layer that is currently in bad condition may remain. Both of these possibilities make the home more susceptible to leaks and potential water damage, which can cost a fortune to repair. They can also increase roof repair costs over time.

When You Need to File a Warranty Claim

Many roofing materials have a lengthy warranty period that can give you peace of mind when making this rather expensive investment. However, manufacturers are well aware of the fact that layering shingles can decrease the effectiveness and overall performance of their materials. Therefore, many roofing materials manufacturers have a warranty clause that invalidates the warranty if the shingles are layered. This means that you could be responsible for repair issues that may otherwise have been included in a warranty that could have lasted for up to or even more than 40 years in some cases.
