What kind of roofs is this service for?

Mainly domestic flat roofs such as extensions, porches, garages and garden buildings where EPDM is a suitable long-life covering.

Is EPDM a good choice for a home extension roof?

Yes — it’s a durable, low-maintenance option and gives a very clean finished look when installed properly.

Can you replace an old small flat roof with EPDM?

Yes, where the structure is suitable. We’ll assess the existing roof and advise on the correct scope before quoting.

Do you pay attention to the visible finish as well as waterproofing?

Absolutely. On flat roofs visible from upper windows, the neatness of the finished roof matters just as much as the waterproof detail.

Will I get photos of the completed roof?

Yes — we photograph completed jobs so you can see the finished roof and details clearly.

Do you cover Cheltenham and surrounding areas for flat roof installations?

Yes — we cover Cheltenham, Gloucester and the wider surrounding area for suitable flat roof projects.

How do I get a quote?

Send a few photos and your postcode, or book a visit, and we’ll quote based on the roof size, access and required detail work.

Service overview

Flat Roof Installations — done properly, the first time.

What it is

A flat roof installation is the full construction of a new waterproof roof covering on an extension, porch, garage or similar flat-roof structure, finished in EPDM with properly formed perimeter and wall junction details.

Who it's for

Ideal for homeowners improving or extending their property, replacing an aging small flat roof, or finishing a new structure that needs a durable, low-maintenance waterproof covering.

When you need it

Best booked when building a new extension, replacing a failing small flat roof or upgrading from a tired covering that has reached the end of its useful life.

Why professional matters

A new flat roof only performs as well as its edges, outlets and junctions. Good installation prevents the common problems that show up later: lifting edges, standing water, weak corners and leaks at the wall line.

What happens if ignored

The cost of putting it off.

Flat roofs are judged years later at the weak points: corners, trims, outlets and wall details. Get those wrong and even a new roof can disappoint quickly.

Real risks

Leaks forming at edges and upstands if the detailing is rushed or poorly bonded.
Premature wear when the deck below or perimeter detail is not prepared correctly before the covering goes down.
Standing water around weak falls or outlet details, shortening the life of the roof surface.
Untidy finishes that make a new extension look incomplete, even when the rest of the build is smart.
Paying twice because the cheapest install omits the detail work that actually keeps the roof weather-tight.

Common mistakes

Choosing on price alone without checking the quality of previous finished flat roof work.
Focusing only on the membrane and not the edge trims, wall flashings and outlets.
Letting multiple trades share responsibility so no one clearly owns the finished waterproofing detail.
Accepting a roof with poor visual finish because it ‘won’t be seen’ — these are often the same details that fail first.
Leaving old weak sections beneath a new covering instead of starting with a sound installation base.

Our process

A clear, five-step system.

01

Step 1 — Inspection & measure-up

We assess the structure, dimensions, edges, wall junctions and drainage points so the installation is planned properly before any material is laid.
02

Step 2 — Preparation

The roof base is checked and prepared, with attention to the condition of the deck and the details that will carry the finished EPDM covering.
03

Step 3 — Installation

The EPDM system is laid and finished carefully, with clean lines, neat perimeter detailing and secure junctions around walls, edges and any penetrations.
04

Step 4 — Finishing

Trims, edges and visible details are checked for both waterproof performance and visual finish — especially important on extensions and porches seen from upstairs windows.
05

Step 5 — Handover

We photograph the completed roof and talk you through the finished installation, along with practical advice on looking after it.

Benefits

What you actually get for your money.

Concrete outcomes — not marketing claims. Every benefit below is verified on every job we leave.

Clean modern finish

A well-fitted EPDM roof looks smart from every angle, especially on extensions and porch roofs visible from upper floors.

Low-maintenance roofing

EPDM is durable and straightforward to look after when installed correctly on the right base.

Strong edge detailing

Good perimeter work is built in from day one, helping the roof stay weather-tight where many failures usually start.

Ideal for domestic flat roofs

Extensions, garages, porches and garden rooms all benefit from a clean, durable flat roofing finish.

Professional installation throughout

Not just the field of the roof — the corners, wall details and visible finishes get the same care.

Real completed examples

You can see the standard of finish in the job photos throughout the site, not just a stock image.

In depth

The technical detail behind every flat roof installations job.

A good flat roof install should look simple when finished. That simplicity comes from careful preparation and neat detailing, not shortcuts.

Fully insured

fully insured, full RAMS, certificates on request before any booking is confirmed.

Materials we work on

We install EPDM flat roofing on suitable domestic structures including extensions, porches, garages and garden buildings, with the surrounding edge and wall details finished to suit the property.

Methods we use

Each installation starts with assessing the roof base and the visible detailing, then laying and finishing the EPDM system cleanly so the finished roof is both watertight and visually tidy from overlooking windows and garden level.

Variations of the service

Typical installation work includes new extension roofs, replacement small flat roofs, porch roofs, garage roofs and other domestic flat roof areas where a clean EPDM finish is the right fit.

Situations it applies to

Customers book this service during home improvements, extension projects, upgrades of older small flat roofs and when they want a more durable, neater-looking finish than the roof they are replacing.

Residential vs commercial

This service is primarily aimed at residential flat roof work where finish quality matters as much as waterproofing — especially on visible roofs around the home.
