Flat Roof Installations
Element Roofing Services installs, replaces and maintains flat roofs for homes and businesses across Oxford, Oxfordshire and The Cotswolds. As flat roof specialists, we work with High Performance Felt, EPDM Rubber, GRP Fibreglass and Triflex liquid waterproofing on everything from small extension and garage roofs to large commercial units, backed by over 10 years of experience and 100+ completed projects.
What Our Flat Roof Service Covers
Our flat roof service covers new flat roof installations, full replacements, repairs and ongoing maintenance for domestic, residential and commercial properties. That includes extensions, garages, dormers, porches and larger commercial roofs. Every project starts with a free site visit, where we check the existing covering, the deck beneath it and the drainage, then recommend the system that suits the property and how the roof will be used.
A full flat roof replacement means stripping the old covering, inspecting the deck, upgrading the insulation where building regulations require it, and installing a seamless, watertight system that is low maintenance and thermally efficient.
Flat Roofs Built for Oxfordshire & The Cotswolds
Flat roofs are a familiar sight across Oxfordshire, from rear extensions on Victorian terraces in Oxford to dormers, garages and commercial units in towns like Witney, Bicester, Banbury and Abingdon-on-Thames. Many local properties are listed or sit within conservation areas, which can affect what is permitted, so local knowledge matters. We understand the planning requirements across the county and specify every flat roof to suit the building, its surroundings and the way it will be used.

Frequently Asked Questions
Which flat roofing system is best?
It depends on the roof and how it will be used. EPDM Rubber offers a long lifespan for most domestic roofs, GRP Fibreglass is the best choice where people will walk on the roof, Triflex liquid waterproofing suits roofs with lots of details or penetrations, and High Performance Felt is a dependable option for garages and smaller roofs. We recommend the right system for your property during your free site visit.
How long does a flat roof last?
High Performance Felt typically lasts 15 to 20 years, GRP Fibreglass 25 to 30 years and EPDM Rubber 25 to 40 years when properly installed. Lifespan depends on the quality of the installation, the condition of the deck and how well the roof drains.
How much does a new flat roof cost?
Every roof is different, so we don’t publish set prices. The cost depends on the size of the roof, access, the condition of the deck and the system used. We provide a free, itemised quote after a site visit, so you know exactly what is included before any work begins.
How long does it take to replace a flat roof?
Most domestic flat roofs take one to four days. A garage roof usually takes one to two days, an extension two to four days, and a larger or more complex roof up to a week. We confirm the timeline in your quote, so you know what to expect before work begins.
Do I need planning permission or building control approval for a flat roof?
Planning permission is not usually needed for a like for like replacement. Listed buildings and conservation areas are the main exceptions. Replacing more than half of a flat roof covering is notifiable to building control and usually means upgrading the insulation to current standards. We talk you through what applies during your site visit.
Can a flat roof be repaired instead of replaced?
Often, yes. Localised faults such as a split seam, a lifted edge trim or a blocked outlet can usually be repaired. Replacement is the better option when the damage is widespread, the covering is past its expected life or the deck has become soft.
