Beautiful roof

Most roofs have a lifespan of about 20 years after which they get replaced or repaired because they are worn out. If you have an old roof and you are researching on your best options, re-roofing or roof replacement are the common options. Normally, re-roofing is considered less expensive than roof replacement, metal roofing, torch on roofing, and hence affordable to most people. Although re-roofing is not an ideal choice for everyone, understanding the differences between the two options can help you make the right decision as a homeowner.

What Is Re-Roofing?

Reroofing is involves layering one set of new shingles over an existing set of old shingles. This process can only be done once and hence, if you already have two layers on your roof, re-roofing is not an option to you. Since re-roofing does not involve removing the existing shingles, the process takes less time and labour making it less expensive.

What Is A Roof Replacement?

Roof replacement on the other hand involves tearing the roof down and then putting on a new felt paper and shingles. It therefore involves removing the old roof entirely and replacing it with a new one. Roof replacement can be done at any time regardless of the number of shingle layers on the roof. However, it may need more time and skilled labor and hence it is more expensive than reroofing.

When Re-Roofing Is Recommended

Reroof is highly recommended when your roof is in good condition and is nearing the end of its lifespan. This will help the old roof to perfectly support the new layer of shingles. Since the roof is old, you can do a roof repairs when the existing roof has minor issues or leaks. However, if the existing roof is soggy, has major water damages or missing shingles, reroof should not be done. It is also recommended you reroof the entire roof rather than doing it partially to avoid doing it in future.

When Re-Roofing Should Not Be Done

If you are having more than one layer of shingle, you should not reroof whether you are hiring a roofer or doing it yourself. This is because, you may not be able to drive nails through the many layers to hold the new layer of shingles. In addition, it becomes hard to see what is beneath all the layers and a lot of problems may not be noticed and hence remain unfixed.

Although most roof problems can be spotted even without removing the shingles, you may not identify all the problems and after re-roofing they persist. In fact, re-roofing is not the best choice because the problems are covered and not fixed. In addition, if you reroof only a section of your roof, you may end up having a section of your roof being thicker than the others making it noticeable from a distance.

When roof replacement is recommended

This is the best option in fixing roof problems. It should be carried out if your roof has more than one layer of shingles or if your roof has more problems e.g. sagging, major water damage and missing shingles. Additionally, if the shingles are worn out, replacement is the best option to fix the problem instead of covering it.

It is not worth saving money to reroof your house only to replace the same roof in a short period of time. It turns out to be costly than just replacing the entire roof. Therefore, roof replacement is safer and long lasting to fix all your roof problems.
