Flat Roofing
Expert Flat Roofing in Hertfordshire You Can Trust
Flat roofs are more common than many people realise: garage tops, rear extensions, dormers, balconies and the large roof areas of shops and industrial units. Because rain drains slowly across them, small splits and blisters turn into leaks faster than they would on a pitched roof. We repair and replace flat roofs in Hemel Hempstead and across Hertfordshire, Hampshire and Surrey, and we survey each one free of charge before recommending anything.
Three main systems cover almost every flat roof we see. Felt is a layered covering that remains a practical choice for garages and outbuildings. GRP fibreglass cures into a single hard skin that suits balconies and extensions. EPDM rubber is laid as one large sheet with very few joints, which makes it well suited to bigger roofs. We explain how each fits your building, how you use the roof and your budget, so the choice you make is an informed one.

Why choose us
Why Choose Our Flat Roofing Services in Hemel Hempstead, Hertfordshire
Felt, GRP and EPDM Under One Roof
Because we fit all three systems, our recommendation is based on your roof rather than the single material a contractor happens to stock.
Repair or Replace Advice
The free survey shows whether a localised repair will hold or whether the whole covering has reached the end of its life.
Domestic and Commercial Roofs
From a single garage to a flat-roofed office or industrial unit, we plan access and timing around the property.
Fully Insured Contractor
Public liability insurance covers the flat roofing we carry out, which matters on busy commercial sites as much as at home.

Pricing
What Influences the Cost of a Flat Roof
Flat roof prices vary from building to building, so we confirm the figure after a free survey based on these factors.
- The area of the roof in square metres.
- The system chosen: felt, GRP fibreglass or EPDM rubber.
- Whether the deck boards beneath need replacing because of water damage.
- Details such as upstands, roof lights, outlets and edge trims.
- Access to the roof, particularly on commercial buildings and balconies.

The work
Our Flat Roofing Process
The main stages of the job, from the first inspection to the final check.
Flat Roof Survey
We check the covering for splits, standing water and failed seams, and test whether the deck beneath is still firm.
Choosing the Right System
You receive our recommendation for repair or replacement, the reasons for choosing felt, GRP or EPDM, and a free quote.
Laying the New Covering
Old material is removed where needed, damaged decking is replaced, and the new system is laid and finished at every edge, upstand and outlet.
Final Inspection and Sign-Off
After checking that water runs towards the outlets and the edges are sealed, we review the completed work with you and confirm everything has been done as agreed.
