Porch Roof Fitting

Flat Roofs are a common feature on properties across the UK, whether it’s on a garage, extension or the entire building. In most cases, they’re used because they’re quicker and cheaper to install. But given the various benefits of a pitched roof, it’s understandable that some people want to upgrade their flat roof.

In this post, we’ll discuss the practicalities, benefits and costs when upgrading a flat roof to a pitched one.

Benefits of a flat-to-pitched conversion

First of all, it’s worth looking at the reason behind a flat-to-pitched conversion. While flat roofs are cost-effective in the short term, they’re much more prone to leaks than their pitched counterparts. Flat roofs typically have a small slope of less than 1 degree (1:80 as a ratio). That makes it easier for water to run off, but over time water can eventually pool on the roof as the materials wear away and timbers deflect,  as is their characteristic.

As many flat roof owners will know, they need a lot more maintenance to prevent leaks, as well as requiring replacement much more frequently. Even with the best materials and flawless installation, flat roofs are limited to around 30 years
