Sloped Roof vs Flat Roof: Their Pros and Cons

Choosing between the sloped roof and flat roofs for your structure greatly depends on you, the homeowner. Sloped roofs have different styles like gable, hipped or lean-on, or flat roofs which have a wide space on top. But more than your personal preference, technical aspects should also be considered in choosing one. 

Technical Consideration should be: 

  1. Installation & Construction
  2. Roof Longevity 
  3. Cost Comparison
  4. Energy Efficiency
  5. Maintenance 

Sloped Roof vs Flat Roof

Flat Roofs 

Installation & Construction

Flat Roofs are easier to construct, you just have to consider providing a little slope for the drainage of water. The vapor barrier, insulation, and waterproofing should be well-applied and installed to prevent leaking and other issues.

Roof Longevity 

Flat Roofs have a shorter lifespan, especially depending on the material used. Usually flat roofs last from ten to fifteen years. 

Cost Comparison

Compared with installation cost, it is lesser because it requires lesser materials and the structure is simple therefore lesser labor cost.

Energy Efficiency

Due to the wide area, its reflective ability is much larger. It is also solar panel friendly and can transition to a green roof due to the direct heat. 

Maintenance

Because of its flat surface, it is more susceptible to damage from the accumulated rain and snow. But, maintenance is easier to access. Therefore, any routine clean-up and maintenance are easily done and leaks can be then rectified before it worsens.

Sloped/ Pitched Roof 

Installation & Construction

Sloped/ Pitched Roofs are harder to install because you are working on height considering their steep slope. It requires structural roof framing or even more reinforcement (depending on the weight of the material) to carry the extra load of the roofing. 

Roofing Longevity 

Roofing materials like shingles and tiles are made to last longer which can last for 50 years and can go longer if invested with newer roofing materials which are manufactured to have more durability and weather resistance.

Cost Comparison 

Because of the sloped area and each on both sides, more roofing materials are needed and additional cost for the structural framing. You will also consider safety garments and additional labor costs for working on sloped heights as it can be dangerous without proper training. The cost of the roofing material varies widely depending on the material. 

Energy Efficient 

Sloped/ Pitched Roofs are less energy efficient but because of the new trends in the roofing materials, you can now invest in or convert your sloped roof using solar tiles or shingles, eco-friendly roofing materials, and upgrading it to a green roof. Any of these will also cost you additional reinforcements. 

Maintenance 

Just like the flat roofs, many problems may arise over time; the only difference is that it is harder to maintain and monitor because of their slope & height. Problems like moss growth, accumulated hail and snow, and damages due to strong winds can also be damaging if left unfixed. 

Conclusion:

As it imposes different pros and cons and if you are still having a hard time choosing your roofing type between a sloped/pitched roof and a flat roof, you can consult with your local roofing specialist which could help you with price comparison using both roofs. They could also help you with the large market of roofing materials and help you choose the reasonable material with your budget.
