Some builders install flat roofs because it is cheaper to do so than installing a pitched roof. However, flat roofs can cause various problems, so if you haven’t already installed your roof it’s well worth considering pitch roofing. If you already have a flat roof and are wondering whether to convert to a pitch, here are the main things to think about.

Problems associated with flat roofs

Leaks are extremely common with flat roofs. This is typically either because they have been poorly fitted which allows water to collect on the roof and seep through any gaps in the waterproofing, or because they haven’t been maintained well, or because of wear and tear from UV light, heavy rain, or from people or animals walking on it. If you have a flat roof you may well have experienced leakage, which can very quickly lead to damp and mould inside the property.

Furthermore, flat roofs don’t tend to last as long as pitched roofs, even if they are well maintained. The expected lifespan of a flat roof is around 20 to 30 years, although you may start to experience problems even before your roof has been in place for 10 years.

Benefits of pitched roofs

Pitched roofs are much better at keeping rain out as the water rolls down the slope and away rather than collecting in pools on the surface of the roof. This minimises the length of time the water is retained on the roof, and in turn reduces the chances of leakage. Added to this, the materials used for pitched roofs tend to be better-quality, denser and more durable than those used for flat roofs, so it is even more difficult for rain to penetrate.

In terms of lifespan, pitched roofs tend to be much longer lasting than flat roofs. They are more weather-resistant and easier to maintain, so any minimal damage can usually be repaired easily. Some pitched roof installers will offer a guarantee when installing a pitched roof. At Metrotile, for example, we provide a 40-year weather guarantee, although there is no reason why your pitched roof shouldn’t last well beyond this.

Converting from a flat roof to a pitched roof

If you decide to go ahead with the conversion, one final consideration is planning permission. You may need to seek planning permission if you are changing to a pitched roof. However, if you go for a low pitch you will enjoy the benefits listed above and your planning permission is likely to be approved without any hassle.

At Metrotile, we provide high-quality materials for pitched roofs, including low pitches, as well installing them through our qualified contractors. Our lightweight roof tiles are perfectly suited to low-pitched roofs as they will place very little pressure on the structure of the building.
