The work

Rubber roofing in one piece

EPDM is a synthetic rubber membrane supplied in wide sheets. On a typical garage or extension roof it goes down as one piece, bonded to the insulation or deck, with the edges dressed into trims and taken up the abutments.

It stays flexible in cold weather, it is not degraded by ultraviolet light the way old felt was, and because there are no joints in the middle of the roof there is nothing there to fail. Corners and outlets are made up with matching flashing pieces.

  • Single-sheet coverage wherever the roof geometry allows it.
  • No hot works, which suits a roof next to timber cladding or a window.
  • Insulation and falls dealt with, not just a new skin over old problems.
  • Manufacturer-matched trims and corner pieces rather than improvised details.

What's included

What rubber roofs covers

  • Deck preparation

    Old covering off, deck repaired, and a smooth substrate for the membrane to bond to.

  • Falls and insulation

    Firrings or tapered insulation so water runs off, with the insulation upgraded where possible.

  • Single-sheet membrane

    EPDM cut to the roof and bonded down, in one piece wherever the roof allows.

  • Trims and edges

    Aluminium or GRP edge trims, drips and kerbs finished neatly.

  • Corners and penetrations

    Pre-formed corners and pipe flashings bonded and rolled.

The price

Rubber Roofs costs

What rubber roofs costs comes down to what you actually have, not a price list. Two jobs that sound identical can be an hour of work or a week of it, which is why we do not price roofing over the phone. We come and look, then put a figure in writing.

  • Roof area, and whether one sheet covers it.
  • Deck repairs found once the old covering is off.
  • Insulation thickness the build-up allows.
  • Number of penetrations, kerbs and upstands.

How it works

How a rubber roofs job runs

  1. Step 01

    Measure and check

    We check whether the roof can be covered in a single sheet, which is the main advantage.

  2. Step 02

    Quote

    A price naming the membrane, insulation and trims, and how the abutments are finished.

  3. Step 03

    Fit

    Deck sorted, insulation laid, membrane bonded and rolled, edges trimmed.

  4. Step 04

    Test the outlets

    Water run to the outlet to confirm the fall, then the site cleared.

Questions

Rubber Roofs: common questions

The questions we get asked most often about this work. Anything else, ring and ask.

Still not sure? Ring and ask. It is usually quicker than typing it out, and you will speak to the person who would do the work.

How long does EPDM last?

The membranes we fit carry long manufacturer life expectancies, and the failure point on a rubber roof is nearly always a detail at the edge rather than the sheet itself. That is why we spend the time on trims and upstands.

Can I walk on it?

For maintenance access, yes, carefully and without dragging anything sharp across it. If the roof is going to be used as a terrace it needs a walkway or paving system designed for that, which changes the build-up.

Does it come in grey rather than black?

Standard EPDM is black. If the roof is overlooked from above and appearance matters, there are lighter single-ply alternatives and we can price one.

Can EPDM be laid in cold weather?

It is more tolerant than felt or fibreglass because nothing has to cure and there is no flame, but the adhesives still have minimum temperatures. In a cold snap we will tell you if it is worth waiting a few days.

What happens where the rubber meets the house wall?

The membrane is taken up the wall as an upstand and finished under a flashing or into a chase, never just stuck onto render. That junction is where flat roofs leak, so it gets the most attention.
