Flat Roofs in Richmond

Rubber, Felt and GRP Flat Roofs in Richmond

Where a flat roof doubles as a balcony or terrace, the covering has to cope with feet, furniture and planters as well as rain. GRP fibreglass is often chosen for this, curing to a hard, jointless surface that can be finished with a textured top coat. Ashlar Roofing installs and repairs GRP, EPDM and felt flat roofs in Richmond, across TW9 and TW10 and the London Borough of Richmond upon Thames.

Turning an existing flat roof into a terrace, or adding railings, can need planning permission, particularly in a conservation area, so Richmond upon Thames Council is worth contacting before anything is designed. Existing GRP roofs that have cracked or crazed can often be repaired by grinding back the damaged area and laying new matting and resin. For a straightforward recovering of an existing balcony or flat roof, we inspect, recommend a system and quote, with work starting once you agree.

What's included

What a New or Repaired Flat Roof Includes

The main parts of the job, each listed in your quote.

  • An inspection of the existing deck and timbers, so a new covering is laid on a sound base rather than over hidden rot.
  • A choice of rubber, felt or fibreglass covering, matched to the roof's size, use and budget so you are not paying for more than it needs.
  • Insulation options when the roof is replaced, helping to keep the room below warmer in winter and cooler in summer.
  • Correct falls and outlets, so rainwater drains away instead of pooling and wearing out the covering early.
  • Properly detailed upstands, trims and flashings where the roof meets walls, which is where many flat roof leaks begin.
  • Repairs to splits, blisters and failed seams on existing roofs, where the deck is sound and a repair makes more sense than replacement.

Pricing

Pricing a Flat Roof in Richmond

The cost of a flat roof or balcony covering in Richmond reflects:

  • The size of the roof and how many upstands, outlets or rooflights it has
  • The membrane chosen (EPDM, torch-on felt or GRP)
  • The condition of the deck and joists once the old covering is lifted
  • Whether insulation is added to bring the roof up to current standards
  • Access, including whether materials have to be carried through the house

How it works

How Flat Roofing in Richmond Is Arranged

What happens from your first call or message to the finished work.

  1. Book a Survey

    Tell us about the roof by phone or through the form. Photos on WhatsApp of the roof and any stains inside help us understand the problem before we visit.

  2. Inspection and Quote

    We check the covering, deck, falls and edge details, then recommend a repair or a replacement and set out a quote that is agreed before work starts.

  3. Preparing the Roof

    On the day, the old covering is stripped where needed, the deck is checked and any rotten boards are replaced so the new roof has a solid base.

  4. Laying and Finishing

    The new membrane or repair is installed with its trims and flashings, then we review the completed work with you and confirm everything has been done as agreed.

FAQs

Flat Roof Questions from Richmond Homeowners

Do you cover flat roofing in Richmond?

Yes. Ashlar Roofing works across Greater London, including Richmond and the TW9 and TW10 postcodes. We repair and replace flat roofs on extensions, garages, dormers and commercial buildings.

Can a flat roof be repaired rather than replaced?

Often, yes. Isolated splits, blisters or a failed seam can be repaired if the deck beneath is dry and sound. If the covering has failed in several places or the boards have gone soft, replacement is usually the sounder choice.

What should I send before a flat roof survey in Richmond?

Photos of the roof from a window, any internal stains and the edge where the roof meets the wall are all useful. Send them on WhatsApp with your postcode and we can prepare for the visit.

Should I add insulation to my flat roof?

If the roof is being replaced, it is a good time to consider it. A warm roof build-up places insulation above the deck, which helps keep the room below comfortable and reduces the risk of condensation in the roof structure.
