Flat Roofing for Homes & Businesses
A flat roof has little pitch to shed rainwater and swings between summer heat and winter frost, so both the covering and the deck beneath it need to be right. Done well, a flat roof gives a watertight, low-maintenance and cost-effective cover for extensions, garages, dormers and commercial units.
Steadfast fits three main systems: torch-on felt, EPDM rubber and fibreglass (GRP). Felt is economical on large areas, rubber is one continuous, flexible sheet and fibreglass gives a hard, joint-free surface. We explain the differences plainly so you can choose the right one for your roof and budget.
We offer a FREE drone roof inspection to help assess the condition of your roof and identify potential issues, followed by a FREE, no-obligation quote. Where a roof only needs a repair rather than a new covering, we tell you that too. We work across Maidstone, Kent and South East London.

Explore Each Flat Roof System

Signs You Need a New Flat Roof
Pooling Rainwater
Puddles that sit for days point to sagging boards or poor falls, and standing water shortens roof life.
Blisters or Splits
Bubbles, cracks and lifting edges let moisture under the covering, soaking the deck before a leak shows.
Stained Ceilings Below
Staining below a flat roof means water has found a way through, and the sooner it is traced the better.
An Ageing Garage Roof
On older garage and extension roofs, patching can end up costing more over time than a new covering.

FREE, No-Obligation Quotes. Your quote costs nothing and commits you to nothing, so you can make an informed decision about your property.
Size & Access
Larger roofs need more material and labour, and roofs that are hard to reach may need scaffolding or extra equipment.
Condition of the Deck
If boards underneath have gone soft, replacing them adds to the work, though it is essential for a lasting roof.
Choice of Material
Felt, EPDM rubber and fibreglass differ in material and labour, so the system you choose affects the price.
Edge Details & Outlets
Rooflights, pipes, upstands against walls and extra outlets each need careful detailing that adds time.

Our Flat Roofing Process
Inspecting the Existing Roof
We assess the condition of the surface, edges and outlets to work out whether a repair or a new covering is the sensible route.
Preparing the Deck
The failed covering comes off, the boards are checked, and any soft or rotten sections are replaced so the new roof has a firm base.
Laying the New Covering
The chosen system is bonded to the deck, whether that is layered felt, a single EPDM membrane or a fibreglass laminate.
Finishing Edges & Details
Trims, upstands and outlets are formed and sealed, and the site is cleared once the roof is finished.
