Deciding whether to go for a total roof replacement or a re-roofing can be a tricky situation for most homeowners. However, in most cases, roof replacement experts may recommend the former.
This is because, with age, roofing material becomes weak. So placing new roofing material over the top of the existing shingles may not be a smart decision. Although it may look tempting, mainly because of the low cost, sooner or later, age will catch up with the old parts and which will then affect the entire roofing system. A complete replacement is an ideal and worthwhile investment.
Below are some advantages of a roof replacement over a re-roofing.
Benefits of a Roof Replacement
Fixes the Faults
Putting new roofs over old roofs only conceals whatever faults that may exist in the old roofs. Oftentimes, you may not know of those faults, so you may not be fixing them by re-roofing. Some common roof faults include an excessive buildup of moisture in the roof, rot, and pest infestation. A total replacement is a sure way to fix those faults and ensure good long-lasting roofs.
Provides Maximum Protection
Roof shingles can be bumpy or wavy and are often overlapping. Hence, they do not provide an even surface that is required to maintain a tight seal when overlaying them with new roof shingles. On the other hand, replacing your roof gives you the advantage of having a solid base for the roof shingles to lie flat. A securely placed roof shingle reduces the chances of leaks. Also, it makes it less likely for your roof to be blown away during a storm.
After a while, old roofs will start to leak. This will in turn cause water buildup in the ceiling and walls, which could lead to wall bulging or cracking. A leaky roof also provides a thriving environment for mold and mildew to grow. These molds are known to cause allergies and other serious health concerns.
Total replacement of your old roofs eliminates the chances of having a leaking roof. It also ensures that your home is safe for you and your family.
Investing in a new roof gives you the privilege of choosing from a variety of energy-efficient materials that would keep you warm during the winter and cool during the summer. Also, because a total roof replacement allows the roof shingles to be laid properly, it helps to prevent energy loss. This could keep your energy bills down.
Reduces Weight Strain
Some roofs may not be able to take on extra weight. So, overlaying your old roof with a new one may increase the strain on the old roof, which may cause additional problems. It even gets worse if you stay in a region with heavy snowfall. With all that weight, your roof may just cave in. Installing a new roof saves you all that stress.
Proper Leak Installation
One of the problems of overlaying old roof shingles with new ones is that it prevents water and ice leak barriers from being properly installed. This is especially necessary if you stay in an area with extreme weather conditions, you wouldn’t want ice leaking through those old roofs. But with new roofs, you can be assured of proper leak installations.
Improves the Curb Appeal
Changing your roofs can improve the aesthetic value of your house, as your old roofing may be outdated. There are a variety of modern roof shingles that can give your house a sleek look. You can also choose roof designs that reflect your style and also complement the natural landscape of your environment. While this may seem like a cosmetic benefit and unnecessary, if you decide to sell your house in the future, your curb appeal is often the first impression buyers have of your home.
Most roofing companies offer a warranty when you purchase from them. If you should notice any faults in the roof within the period of the warranty, the company will cover the costs of the repairs. However, if you choose to opt for a re-roofing, most roofing companies would be reluctant to cover the costs of any damage that may occur.
Replacing your old roofs has many advantages over overlaying new roofs over your existing roof. However, if you’re still unsure of which choice to make, then you should speak to a roofing expert about which option would be most suitable for your home.
