A long-lasting, professional roofing solution designed to protect your shed or outbuilding for decades, not just a few years. Never replace your shed roof again. 

Firestone (Elevate) EPDM shed roofs supplied & fitted by a fully qualified EPDM installer, with up to a 50-year life expectancy and a 25-year manufacturer warranty.

Based in Chesham, I supply & fit Firestone (Elevate) EPDM shed roofs across Chesham and the surrounding areas.

EPDM rubber roofing is a commercial-grade roofing system, widely used on flat roofs across the UK and beyond. It is not a temporary covering like felt. When correctly installed, EPDM offers: 

• Life expectancy of up to 50 years 

• Excellent resistance to UV, rain, frost, & temperature changes 

• Long-term flexibility without cracking, blistering, or drying out 

• A clean, modern finish suitable for sheds, workshops & garden buildings. 

• 100% waterproof solution 

Never replace your shed roof again. In most cases, EPDM is installed as a single-piece membrane, meaning there are no joins to fail, one of the most common causes of felt roof leaks. This makes EPDM the best long-term option for flat or low-pitch shed roofs. 

Firestone (Elevate) EPDM - Always Used 

I only install Firestone (Elevate) EPDM, a proven, industry-leading membrane used on commercial & domestic roofs worldwide. Cheaper EPDM alternatives exist, but they do not offer the same consistency, performance, or warranty backing. Using a premium membrane ensures reliability and longevity. 

Fully Qualified EPDM Installer 

Your roof is installed by a fully qualified Firestone EPDM installer, following manufacturer-approved installation methods. The performance of EPDM depends heavily on correct preparation, adhesive use, edge detailing, and finishing. Poor installation, not the material itself, is the main reason EPDM roofs fail. This is not rushed or “quick-fix” work. 

What’s Included with an EPDM Shed Roof

A supplied & fitted EPDM roof typically includes: 

• Firestone (Elevate) EPDM membrane cut precisely to size 

• Correct adhesives, trims & edge finishes 

• Removal of existing felt (where agreed) 

• Inspection of the timber roof deck 

• Professional installation & full perimeter detailing 

• Clean, tidy completion 

 If the deck beneath the old roof covering is damaged or rotten, this will be shown and discussed before any additional work is carried out. 

Where EPDM Is Suitable 

EPDM is ideal for: 

• Garden sheds 

• Workshops 

• Garden rooms & home offices 

• Bike stores & log stores 

• Flat-roofed outbuildings 

• Small garages & similar structures 

If the roof is flat or low-pitch, EPDM is almost always the correct solution. 

• 25-year manufacturer warranty on Firestone EPDM supplied 

• 12-month workmanship guarantee on installation labour 

Please note: EPDM membranes are cut to size and are non-refundable once ordered or cut. 

Everything is explained clearly before work starts, no fine print and no surprises.

Why is EPDM more expensive than felt? 

EPDM is a commercial-grade rubber roofing system with a life expectancy of up to 50 years. Felt is a short-term product that typically needs replacing every few years. EPDM costs more upfront but is far cheaper over its lifespan. This is a permanent waterproof solution. 

What’s included in a supplied & fitted EPDM roof?

Firestone (Elevate) EPDM membrane, correct adhesives and trims, professional installation by a fully qualified installer, and full perimeter detailing. Removal of existing felt and deck inspection are included where agreed. 

The deck is inspected once the old covering is removed. If repairs are needed, they’re shown and agreed before any extra work is carried out. 

Do you offer a guarantee? 

Yes. EPDM supplied comes with a 25-year manufacturer warranty, plus a 12-month workmanship guarantee on installation labour. Why do materials need to be paid for in advance? EPDM membranes are cut to size for each roof and cannot be reused or returned. Once ordered or cut, materials are non-refundable.
