What is the price of a new flat roof?

How much does a flat roof cost?

Not every flat roof needs immediate replacement following a leak but if your roof persistently fails then it’s no longer economical to keep on paying out for repairs.

The lifespan of a flat roof depends ultimately on the materials used during construction. Those made from traditional materials such as felt and asphalt have considerably less durability than their modern counterparts and this should be a factor when considering costs.

Opting for cheaper flat roof solutions might seem appealing initially but eventually such a decision is likely to hit you in the pocket when the system prematurely fails.

A good flat roofing product will last longer and will involve less – if any – maintenance – which makes it a cost effective decision in the long-term.

The cost of flat roof replacement depends on a number of factors including the size of the roof to cover, the chosen system, materials, accessibility, location and the required labour to fit the new roof.

It is impossible to give an accurate figure for a new flat roof without all these considerations however we can provide our customers with a rough estimate based on the dimensions of the project prior to undertaking a full evaluation of the site.

Here at High Tech, we have a minimum project value which is set at £800 which is the starting cost for a single ply PVC membrane roofing product for a porch-sized area.

The price increases depending on the size of the area to be covered, whether the old roofing system needs to be removed, whether the roof needs re-boarding and the shape and accessibility of the building.

PVC flat roofing systems were initially developed in Europe in the 1960s in an effort to increase the lifespan and quality of flat roofs, mostly on commercial premises. However, today PVC products are as popular on domestic properties as they are on shopping centres, leisure venues and office blocks and are fast becoming the flat roof of choice.

One of the major benefits of PCV membranes is the protection it offers from the elements. The heat-welded seams maintain flexibility during their lifetime which helps them to counteract the effects of sun damage and frost. The chemical composition of PVC also ensures it is impervious to pooling water.

While the initial outlay of installing a PVC roof might be more than traditional flat roofing materials such as felt, PVC roofing membranes are one of the least costly in the long-run in terms of maintenance (and air-conditioning in commercial buildings).
