Flat Roofs Orpington – Roofers Orpington by Crown Roofers

For flat roofing in Orpington, Roofers Orpington by Crown Roofers installs, repairs and replaces felt, GRP fibreglass and EPDM rubber roofs on extensions, garages, porches, dormers and commercial buildings across BR5 and BR6.

Flat Roofing Services in Orpington

Flat roofs suit the many rear extensions, garages and dormer conversions around Orpington – but they are unforgiving of poor workmanship. Nearly every leaking flat roof we are called to has the same causes: not enough fall, a joint or upstand that was never detailed properly, or an outlet that has been blocked for years.

We set out the falls first, use the right system for the roof, and finish the edges, upstands and outlets so water leaves the roof quickly. If the deck below has been soaked, we will tell you before we cover it – not after.

Flat Roof Repairs in Orpington

Splits, blisters, ponding water and perished felt can often be repaired rather than replaced. We patch, reseal and renew flashings and outlets, and we are honest when a roof has reached the point where a repair is throwing money away. Our wider roof repair service covers pitched roofs too.

Flat Roof Systems We Install in Orpington

We work with the three systems that perform best on domestic and light commercial roofs:

  • Torch-on felt – the traditional, cost-effective choice for garages, sheds and simple extensions.
  • GRP fibreglass – a seamless, rigid finish that suits balconies and roofs with trims and detail.
  • EPDM rubber – a single flexible membrane with very few joints, typically lasting well over 20 years.

We will recommend the right system for your roof size, access, budget and whether the surface is walked on – and explain the trade-offs rather than pushing one product.

Frequently Asked Questions – Flat Roofs in Orpington

How long does a flat roof last?

With the right system and proper installation, expect 20–30 years. EPDM rubber and GRP fibreglass generally outlast traditional felt, particularly on roofs that get walked on or hold water.

Usually, yes. Splits, blisters and failed joints can often be repaired or resealed. If the deck underneath is saturated, replacement is the only lasting fix – and we will show you why.

Felt is the most economical, GRP gives a seamless rigid finish, and EPDM is the most flexible and forgiving with very few joints. Roof size, access and use decide it – we will talk you through it on site.

They are low-maintenance rather than no-maintenance. Clear gutters and outlets twice a year, keep moss and debris off the surface, and check upstands after storms.

Yes. Every flat roof we install in Orpington is guaranteed, with manufacturer warranties on the membrane systems we use.
