Roof Conversion: Is it Worth to Convert a Low-Sloped Roof to a Pitched Roof?
Low-sloped roofs, also known as flat roofs, differ from pitched roofs both from the way they are designed to the materials and processes used in the construction. Usually, there are compelling reasons why flat-roofed property owners would choose to convert to a pitched roof. It could be to improve the resale value, change the style, or fix chronic issues.
Whichever the reason behind the need for the conversion, you need to ask yourself whether the conversion will be worth it. Both flat and pitched roofs have unique advantages and disadvantages. Below are some of the factors you need to look at before deciding whether to proceed with the conversion or not.
But before we look at the factors, it’s important to consider your safety and that of anyone who’ll be working on your roof. Ensure to install proper fall protection, such as a barrier for flat roof before allowing anyone on the roof.
Cost is one of the main factors you’ll need to consider. You’ll probably want to know how much each type will cost you. Low-sloped roofs are usually much easier to install than pitched roofs. This means the renovation can be significant if you’re looking to convert from low-sloped to pitched.
However, low-sloped roofs often require consistent repairs and maintenance than pitched roofs. They also hardly last long. Good maintenance can guarantee a lifespan of between 15 and 30 years. Pitched roofs, on the other hand, can last much longer, especially if you use long-lasting roofing materials. It’s, therefore, important to consider both short-term and long-term costs when making this roof conversion decision.
Style is usually more of a personal decision. However, there can be some legitimate reasons you may decide to change the style of your roof. For instance, you could have a property designed with a low-sloped roof. If changing the style to a pitched roof could improve its resale value, it might be in your best interest to proceed with the conversion. Also, if you intend to turn your property into a church building or a commercial retail space, adding a pitched roof can make the building more appealing or grander. Pitched roofs can also shed water more easily and add essential square footage to the inside of your property.
As mentioned above, low-sloped roofs are more susceptible to damage hence the need for frequent maintenance. Ponds, debris, snow, and wind are some of the factors that could cause damage to flat roofs. Any damage needs to be addressed as soon as possible to prevent significant structural damage. But pitched roofs require regular maintenance, as well. Just not as frequent and aggressive as with flat roofs.
There’s a clear distinction between adding a pitched roof over an existing flat roof (keeping the original roof structure) and converting a flat-roofed structure to a pitched roof. Some of the reasons that could merit the addition of a pitched roof over an existing flat roof include to:
Avoid extra costs of completely tearing off an existing flat roof.
Fix a problematic, leaky flat roof.
Add insulation to the property envelope.
Avoid exposing an occupied property to water damage during the construction, especially during a rainy season.
When adding a pitched roof over an existing flat roof, pay attention not to exceed the maximum weight limit. However, you’ll need to first remove all existing layers of roof coverings if the existing roof covering is water-soaked, deteriorated, or has more than one application of any type of roof covering. It’s important to consult a roofing contractor to help in ensuring everything is done right.
