Planning on layering roof shingles? Here are the pros and cons

 

Installing a new roof on top of the old ones will save you time and you also won't have to worry about spending too much on labour or even doing a whole roof replacement project. It only involves getting rid of the damaged portion and replacing it with a newer roof. This may seem to be a good option in the short term, but it won't last for long. First, the damage can continue to grow and eventually affect the whole roof which will only lead to expensive repairs in future. And when it is time to install a new roof, you will have two layers to remove this time and this will end up increasing the total cost of the project.


How additional shingle can affect your roof

First, this extra layer of shingle can decrease the life of the roof. The additional shingles can easily trap heat that can lead to decomposing which means that you will have to replace the roof sooner than expected. According to a survey, layering new roof shingles can reduce the lifespan of the roof by over 40%.

Also, most roofs can only hold one layer of shingles. So if you add another layer, especially if it is of a higher quality than the original roof, the roof will become heavy making it dangerous and also affecting the overall structure of your house. This is precisely why building codes require roofs to have a maximum of two shingle layers. Extra weight also causes issues like sagging, trapping moisture and causing decay in the long run.

It may affect the appearance as well

Layering the roof shingles will indeed make the roof attractive at the beginning. But if you do the layering on top of shingles that are extremely damaged or curled, imperfections will appear all over the roof.

Conclusion

When looking for a quick solution to your roofing problems, layering roof shingles can be a short term solution but don't consider this option when you need a long term investment. This can also decrease your home value thus reducing the price if you plan to sell the home in future. And as a rule of thumb, always seek advice from professional roofingTyler TX technicians before carrying out this project.
