New Flat Roof Rudgwick, West Sussex

The existing flat roof covered the front of the customer’s garage and entrance porch on there property in Rudgwick. The flat roof membrane was felt and had started to leak in the garage section. The customer wanted the flat roof membrane replaced with a high quality, long lasting alternative so the single-ply DuoPly fleece reinforced EPDM new flat roofing membrane fitted the bill perfectly.

The approved contractor removed and disposed of the existing flat roof membrane and deck. The existing flat roof was insulated using a cold roof construction so no additional insulation was required.  They then installed a new structural deck and installed the DuoPly EPDM single ply fleece reinforced new flat roof membrane.  Finally, they installed the black metal edge trims and replaced some uPVC guttering to the main house which was also leaking.

New flat roof Horsham

The customer had had an extension built at the rear of their period Victorian property in Horsham, West Sussex. The architect had designed a modern box shaped extension with external Cedar cladding, new flat roof with flat glass rooflights and grey colour bi-folding doors and windows.  He also wanted a modern flat roof membrane to complement the sleek design so the DuoPly fleece reinforced membrane was perfect for the job. As this was a new flat roof extension, the construction had to comply with the current building regulations of a warm roof. This is to ensure that moisture and condensation are kept at bay.

New Flat Roof Reigate in Surrey

The customer in Reigate had an pre-exisiting flat roof dormer which was 25 sqm and a rear extension flat roof which was 10 sqm.  Both roofs had an existing felt membrane. Unfortunately, the felt roof membranes had split and had started to leak, this was caused due to previous poor workmanship as the felt had only been fitted a few years before.

The approved contractor removed and disposed of the existing felt roof coverings, created a warm roof to comply with current regulations and then installed the DuoPly fleece reinforced EPDM membrane onto new OSB3 structural deck.

New Flat Roof Redhill

New Flat Roof Redhill

A popular town located in the London commuter belt, Redhill is a vibrant mix of period and modern housing. Growth was largely due to the coming of the railways and its popularity as a preferred place to live over the years is evident in some of the most stunning period properties you’ll find – Redhill boasts a significant amount of nationally listed buildings, including Grade II*. Today, surrounded by a network of fast roads and motorways, Redhill is an attractive town both for its accessibility and the period properties it offers.

New Flat Roof RedhillNaturally, these types of properties can come at a price and space can sometimes be the compromise, especially in terraced and semi-detached homes, but the ability to extend the back of a property can easily give a home a completely new lease of life.

Flat roof extensions can work sympathetically with older and period properties. The key to this is essentially the choice of stocks and roof cover. And an EPDM roof membrane is the perfect complementary solution for any period property – with a slate grey appearance it will blend effortlessly with your roof tiles. Unlike the more traditional choice of felt, EPDM will also be durable for years to come. Our approved contractors provide a 20-year warranty on each and every EPDM roof – that’s how confident we are about its superior qualities – but we know that EPDM has been proven to continue to be effective for over 50 years, both from laboratory testing and ‘real’ evidence from installations all over the world.

So if you’re planning an extension or need to replace the roofing system on an existing extension, now is the time to find out more about EPDM! Call us for details of your local approved roofing contractor to arrange a visit and no-obligation quote.

New flat roof kitchen extension in Guildford

The customer in Guildford wanted to enlarge their kitchen to create a modern and functional kitchen/dining/family area, so they built a single storey, new flat roof rear extension.

The approved contractor supplied and installed the DuoPly fleece reinforced EPDM roofing membrane to cover the 28 sqm overall flat roof size, with an aperture for a flat glass rooflight.

It is important when you create a new flat roof extension that you ensure you allow for roof lights or a lantern roof to give maximum light in the new living space. Flat glass roof lights work well with a DuoPly flat roof, to create a stylish and practical solution, and are a popular combination.

Flat Roof Repair Reigate

Lowery Ltd, a firm of Civil Engineers had several buildings and portable buildings at their base in Reigate in Surrey that required attention.

The main roof was 130sqm and had a uPVC single ply membrane installed onto 11mm osb. It was currently leaking due to membrane shrinkage due to poor installation.

Portable building flat roof before

Before – the small portable building flat roof

In addition there was one small portable building roof (18 sqm) that had a uPVC single ply membrane installed onto 18mm osb. It was currently leaking due to multiple puncture holes and membrane shrinkage due to lack of proper mechanical attachment.

Lastly, there were an additional three larger portable building roofs covered with ageing bitumen based felt installed onto 18mm ply. The felt was old but the roofs were not leaking (yet!).

The approved contractor Advanced Flat Roofing, stripped the large roof of the uPVC membrane and over decked using 11mm roofing grade construction OSB3 to increase the roof structural integrity. The roof was then covered using the Duoply fleece reinforced EPDM roofing system. Duoply was particularly suitable for this application due to its low per sqm weight therefore not impairing the roofs current design.

The smaller portable building was stripped back but with this roof the contractor managed to repair the existing 18mm OSB deck and re-use it. This roof had failed because of the multiple holes (due to the low puncture resistance of the uPVC membrane) and also due to membrane shrinkage on the perimeter of the roof. This allowed water ingress via the edge trims. Nearly all other single ply systems need to be properly mechanically attached onto the roof terminations to prevent membrane shrinkage. This is not the case with DuoPly’s shrink free construction.

After – the finished small portable building flat roof

The larger portable building roofs were not leaking and the surfaces were in an acceptable enough condition so the contractor chose to over roof using the Duoply membrane. Duoply is a fully bitumen compatible system which means that in certain circumstances the existing felt/asphalt roof can stay in place saving time, money and most importantly land fill.
