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.

  1. Flat Roof Survey

    We check the covering for splits, standing water and failed seams, and test whether the deck beneath is still firm.

  2. Choosing the Right System

    You receive our recommendation for repair or replacement, the reasons for choosing felt, GRP or EPDM, and a free quote.

  3. 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.

  4. 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.

FAQs

Frequently Asked Questions

What is the best flat roofing option for my property?

It depends on the size of the roof, how it is used and your budget. GRP suits balconies and smaller roofs that need a hard finish, EPDM works well on larger areas, and felt remains a sensible option for garages and outbuildings.

How do I know if I need flat roof repairs or a full replacement?

A single split or lifted seam can usually be repaired. Widespread cracking, soft areas in the deck or repeated leaks point towards replacement, and the free survey confirms which you need.

Do you offer flat roof repairs in Hemel Hempstead?

Hemel Hempstead is our base, and we also repair flat roofs in Berkhamsted, Harpenden, Watford, Rickmansworth and the rest of Hertfordshire, as well as in Hampshire and Surrey.

Are flat roofs suitable for the UK climate?

They perform well when the right system is used and the roof has enough fall for rain to drain away. Modern GRP and EPDM coverings cope with frost in winter and heat in summer.

Are your flat roofing services fully insured?

TNR holds public liability insurance for all the flat roofing work we carry out, on homes and commercial buildings alike.
