Flat Roofs in Walthamstow

Flat Roofing in Walthamstow

Flat-roofed rear extensions, kitchen extensions and garages are common across London, and their roofs work harder than most. Water sits on them longer, the sun bakes them in summer and every join is a possible leak. Felt that cracks, rubber that lifts at a trim and fibreglass that has crazed all let water into the deck below. Ashlar Roofing repairs and replaces flat roofs in Walthamstow and across E17, covering homes and commercial property throughout the London Borough of Waltham Forest.

The right answer depends on what is under the covering. Where the deck is dry and the problem is a single split or a lifted edge, a targeted repair can extend the roof's life. Where the boards have softened or the felt has failed in several places, we recommend stripping back and laying a new EPDM rubber, torch-on felt or GRP fibreglass roof, with the quote agreed before any 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 Walthamstow 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 Walthamstow

Does a replacement flat roof need planning permission in Walthamstow?

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 Waltham Forest Council before work starts.

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.

Can you replace the flat roof on my garage in Walthamstow?

Yes. Garage roofs suit EPDM rubber or felt well. Older garage roofs often have a worn covering over boards that have softened, so we check the deck first and quote for the roof you actually have.

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.
