There are three common roof systems among business establishments in the US. These are flat roofs, low-sloped roofs, and pitched roofs. Each system comes with its own advantages and disadvantages. This article will weigh the pros and cons of each roof type.
Pros And Cons Of Flat Roofs
Of the three commercial roof types, flat roofs may be the most common. They have grown in popularity since the 1920s, and have since become a symbol of modern industry and commerce in the country.
Flat commercial roofs offer many advantages. First and foremost, they can be very cost effective as opposed to more traditional pitched roofs. How come? For one thing, their flat design means that they need less material to cover the building footprint.
The flat design also offers significant savings for business owners the track. With less material involved, flat roofs are easier to install. By the same token, any replacements or repairs that become necessary later on will also be relatively cheap and quick.
Business owners may opt to have air conditioners, satellites, or solar panels on their roofs. Flat roofs can easily accommodate these installations and their maintenance.
Given the many advantages of flat roofs, they do come with only one main disadvantage: they have poor drainage. Standing water from rains and snows can add more weight to the roof and put more strain on the building’s structural integrity.
To ensure that your flat roof will be able to handle heavy rain events, it’s important to hire professional roofers from the start. And as with any other roof type, it’s important to carry out regular inspections and have maintenance done by professionals.
Pros And Cons Of Low-Sloped Roofs
Low-sloped roofs are most commonly used on certain commercial buildings like warehouses and factories. They may also be found on apartment buildings.
The main advantage of using low-sloped roofs is that they allow for stormwater runoff. The sloped design allows for good drainage. Water can be easily directed to drains or saddles. With less standing water to worry about, business owners can feel more confident about managing any potential water damage.
While pitched roofs offer the same advantage in drainage, low-sloped roofs are safer for roofers to work on. The low angle would make it easier for repairs and additional installations to be completed.
The main disadvantage of low-sloped roofs arises in snowy weather. Snow may not melt quickly, which slows down drainage. This means that the roof may be subject to added weight and pressure for prolonged periods.
To guard against roof damage from these weather events, building codes should be strictly followed during installation and repair. Business owners should also be more mindful of conducting regular roof inspections, especially after heavy snows and rains.
Pros And Cons Of Pitched Roofs
Pitched roofs are more commonly used on residential buildings rather than commercial, but you can still see them on some industrial developments.
The main advantage of pitched roofs is that they offer even greater drainage than low-sloped roofs. The steeper incline allows for water, snow and other debris to roll off the roof more quickly. This could significantly reduce the stress on your roof, and may translate to less repairs in the future.
However, the steep slope of pitched roofs means that installation and repairs are more difficult. Roofers must be more careful in maneuvering across the roof, which could slow down work and increase the cost.
All in all, each roof type has its own pros and cons. Your choice over which roof type to go with will depend greatly on the kind of weather your area experiences more frequently. To get expert advice on which roof type will best suit your needs, reach out to our team here.
