Flat Roofs Forest Hill – Roofers Forest Hill by Crown Roofers

Flat Roofing Services in Forest Hill

Half the houses round here have a flat roof somewhere – a rear return, a loft dormer, a garage at the end of the garden. They work well when they are built right and leak quickly when they are not. Practically every failed flat roof we are called to in Forest Hill comes back to one of three things: barely any fall, an upstand or joint that was never detailed, or an outlet blocked solid with leaves off the trees behind.

We set the falls out before anything is laid, pick the system to suit the roof, and finish edges, upstands and outlets so water clears fast. If the deck underneath has gone soft, you hear about it before we cover it up rather than afterwards.

Flat Roof Repairs in Forest Hill

Splits, blisters, standing water and perished felt can often be put right without stripping the lot. We patch, reseal, and renew flashings and outlets – and we say plainly when a roof is too far gone for repairs to be worth paying for. Pitched roofs are covered by our wider roof repair service.

Flat Roof Systems We Install

Three systems handle almost every domestic and light commercial roof in the area:

  • Torch-on felt – traditional and economical, ideal on garages, outbuildings and simple returns.
  • GRP fibreglass – seamless and rigid, good where there are trims, balconies and fiddly detail.
  • EPDM rubber – one flexible sheet with hardly any joints, comfortably 20 years plus in service.

Which one we suggest depends on roof size, access, budget and whether anyone walks on it – and we will spell out the trade-offs instead of pushing a favourite product.

Frequently Asked Questions – Flat Roofs in Forest Hill

How many years should a flat roof last?

Fitted properly, 20 to 30 years is realistic. EPDM rubber and GRP fibreglass tend to go further than traditional felt, especially on roofs that get walked on or hold water after rain.

Most of the time, yes. Splits, blisters and open joints can be sealed or patched. Once the deck below is waterlogged only replacement lasts – and we will show you the evidence on site.

Felt keeps the cost down, GRP gives a seamless rigid surface, and EPDM is the most forgiving with almost no joints. Size, access and use settle it, and we will go through it with you on the roof.

Low-maintenance is not no-maintenance. Clear outlets and gutters twice a year – more often under the trees round here – brush moss and debris off, and check upstands after a storm.

Yes. Every flat roof we lay in Forest Hill is guaranteed, and the membrane systems carry manufacturer warranties.
