Flat Roof vs. Pitched Roof – the Pros & Cons

Price Considerations

Let’s talk cost and get it all in perspective. Replacing a flat roof with a pitched roof will mean two costs – the upfront cost and the cost of maintenance.

Flat roofs always have a lesser cash outlay at the beginning. The installation price for a flat roof is more affordable and materials less expensive compared to pitched roof’s cost. But let’s not forget that down the line, there will be expenses incurred for maintenance and repairs. For example, repairing a flat roof can be more expensive if you are in an area prone to moisture accumulation. So, let’s not just stop at budget and explore further into what affects the entire costs in comparing flat roof vs. pitched roof.

Authenticity to Architecture and Style

When converting your roof, the original aesthetic of your home or building must be considered. There will be modifications done to the existing roof structure so that the roof renovation design will blend seamlessly with the rest of the building once completed.

Hiring the services of an experienced contractor will ensure that if you replace a flat roof with a pitched roof will not pose any awkward result and structural integrity will not be compromised.

Pitched roofs are favoured mostly for the more traditional home designs. Flat roofs are more preferred by modern design aesthetics. Both roof types can support additional space for the structure with flat roofs offering a rooftop space while pitched roofs allow for attic and storage space underneath it.

Weather and Water Accumulation

If heavy rain is a factor where you live, then you have to contend with the moisture that your roof is subjected to. The slope of pitched roofs lessens water pooling making the chance of water damage considerably less. Ponding or water accumulation is common for flat roofs. This can cause problems like mold, rot, and leakage. For this issue, pitched roofs may need less maintenance but the flat roof is also affordable and easier to repair.

Commercial buildings tend to favour the flat roof because it is cheaper to maintain and affords space for equipment such as water tanks or air conditioning units. These must be carefully evaluated by professional installations together with the roofing contractor since they are governed by rules and bylaws in your area. It’s always good to remember that equipment condensation can also contribute to the moisture retained in your flat roof surface.

Roof Maintenance

The roof needs to be periodically checked. Without proper maintenance, a small issue can turn into a major problem if left unaddressed over time. Flat roofs can easily be inspected by the homeowner or in-house building maintenance.

Pitched roofs are trickier and depending on the design and steepness of the pitch, may most likely need to have qualified personnel from a reputable contractor do the inspections. These inspections can be done over more protracted periods but must be regular and done professionally.

Flat roofs require more periodic maintenance work because of moisture retention and possible foot traffic factors but they are easier to clean and repair than other roof types.

A pitched roof may cost more to install at the start because it takes more time and material. However, maintenance-wise, a professionally installed pitch roof will cost less than a flat roof because it requires lesser repairs later on.
