Advantages Of Flat Roof Cost Vs Pitched Roof Cost

The traditional pitched roof is preferred by many homeowners for a wide variety of reasons. For one, many people love the aesthetic look of this type of roof. They give off a traditional feel to a home. On the more practical side, pitched roofs are more efficient in water evacuation. Flat roofs have the tendency to retain water on the top of the home or building and stagnant water can damage not only the exterior of the structure but also the furniture and carpet inside once it finds a way to go down.

In geographical locations that are much affected by rains, where water evacuation is a top priority, pitched roofs are the ideal option. It is important to note, however, that pitched roof requires water to be correctly directed so that there will not be a concentration of water in some areas of the roof. Water should be directed away from the house or building so it will not stagnate onto your home.

Flat roofs estimate, on the other hand, are more suitable for complex buildings or structures with various levels. This is because if you install a pitched roof on this kind of building, it would require a more complicated rafter system. Flat roofs are also more ideal for large spans since building rafters to support large spans are not only complex but also expensive and impractical.

    Removing A Flat Roof Cost

    Factors That Impact The Price Of Flat Roof

    How much will it cost to replace your flat roof?
    • Height of the Roof:

      Tall flat-roofed properties tend to be more expensive that shorter houses, because a flat roofer will need to add a chute to bring the old roofing material down to the bottom.

    • Accessibility:

      Generally, houses in Toronto are closer together than houses in Mississauga, so properties that are not as easily accessible for a dump truck to enter may require the need to remove old flat roofing material using wheelbarrows. This will tend to increase the price of your flat roofing quote. In some cases, the roofer may need to consider going from one roof to another to access the flat roof as well.

    • Existing Flat Roof Layers:

      The number of layers on the flat roof has a big impact on the cost of replacing your flat roof. A flat roof with nothing on it will be much cheaper to install new flat roof material vs a flat roof with 8 inches of the old roofing material. And the cost is ever higher in older from the 1920s -1940s where fibrous material were used on flat roofs.

    • Obstacles:

      The numbers of obstacles on the roof has an impact on the cost for replacing your flat roofs. Obstacles can include siding, vents, AC units and posts on decks. For example, if you have a house with a siding and posts all the way around, then before new flat roofing material can be installed, a roof contractor will need to take the siding off, cut the posts out or flash each posts.
