Flat Roofs in Southall

New and Repaired Flat Roofs in Southall

EPDM rubber has become a popular choice for flat roofs on London homes because it is laid as one continuous sheet on most domestic roofs, leaving very few joins for water to find. EPDM stays flexible in hot and cold weather, which helps it resist cracking. Ashlar Roofing fits EPDM, along with felt and GRP systems, on flat roofs in Southall, across UB1 and UB2 and the wider London Borough of Ealing, for homeowners and businesses.

A rubber roof is only as good as what lies beneath it and around its edges. We start by checking the deck and replacing any soft boards, then bond the membrane and fit purpose-made trims and wall flashings so the edges are as watertight as the middle. Upstands are dressed up the wall and finished under a flashing. On larger commercial roofs, sheets are joined with dedicated seam tapes. The quote is agreed before work begins.

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 Southall 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

Your Flat Roof Questions Answered for Southall

Can a flat roof be laid in wet weather?

Membranes need a dry deck to bond, so flat roofing is planned around the forecast. If rain arrives part way through a job, the roof is protected until work can continue.

Does a replacement flat roof need planning permission in Southall?

Replacing a flat roof covering like for like does not usually need planning permission. If you plan to change the roof's height or shape, or your home is in a conservation area, check with Ealing Council before work starts.

Why does water collect in puddles on my flat roof?

Ponding usually means the roof lacks enough fall, or the deck has sagged. Standing water speeds up wear on most coverings, so a replacement is a chance to correct the falls with tapered insulation or timber firrings.

My Southall 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.
