Flat Roofs in Canning Town

Rubber, Felt and GRP Flat Roofs in Canning Town

A flat roof is never perfectly flat. It needs a gentle fall so rain runs to a gutter or outlet, and when that fall is lost through a sagging deck or poor original work, water pools and wears the covering away. Ponding also adds weight to the deck, which can make sagging worse. Ashlar Roofing deals with ponding, leaks and full replacements on flat roofs across Canning Town, covering E16 and the wider London Borough of Newham.

Correcting drainage is often the most valuable part of a replacement. Tapered insulation boards or timber firrings can rebuild the falls, while new outlets and gutters carry the water clear of the walls. Outlets are sized and positioned so water leaves the roof quickly. Once the base is right, the new membrane is laid and finished with neat trims and upstands. You get a quote that sets all of this out, agreed with you before anything is stripped.

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.

How it works

How Flat Roofing in Canning Town 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

Canning Town Flat Roofing Questions

My Canning Town extension roof leaks after heavy rain. Is it worth repairing?

That depends on the age and condition of the covering. We inspect the roof, check whether the deck is still dry and give a clear recommendation, with a quote for a repair, a replacement or both where each is sensible.

Which flat roof material should I choose?

EPDM rubber suits most domestic extensions and garages, as it is laid in a single sheet with few joins. Torch-on felt is a layered system that works well on larger or more complex roofs. GRP fibreglass gives a hard, jointless finish suited to balconies and roofs with occasional foot traffic.

Do you carry out flat roofing for businesses in Canning Town?

Yes. We take on commercial flat roofs across E16, from the rear roofs of shops to offices and industrial units. Work can be planned to limit disruption to trading.

How long does a flat roof replacement take?

Most domestic extension and garage roofs take days rather than weeks. The exact time depends on the roof's size, the weather and how much decking needs replacing after stripping.
