The flat top

Most dormer tops are felt that has done its time. We strip it, replace soft decking, build in a fall and re-cover in EPDM rubber with proper trims, so the water gets to the front edge instead of ponding at the back.

Cheeks and faces

Rotten cheek boarding taken off, timbers checked, then re-clad and made watertight. Where the cheeks are tile-hung we replace the tiles and battens and re-form the soakers into the main roof.

Flashings back into the roof

The junction where the dormer meets the main slope carries a lot of water. It gets proper lead soakers and a step flashing, dressed in, not taped over.

What is included

  • Leaking dormers traced and fixed
  • Flat tops re-covered in EPDM
  • Rotten cheeks and boarding replaced
  • Tile hanging renewed
  • Lead soakers into the main roof
  • Guarantee terms in writing

How a dormer roof repair is done, step by step

  1. Trace the water. Inside the room and loft first, then outside on the top, the two cheeks, the face and the junction with the main roof.
  2. Photograph it. You see which of the five details has failed before any price is given.
  3. Strip the failed part. Old felt off the flat top, rotten cheek boarding removed, or tile hanging taken off, depending on the fault.
  4. Timber repairs. Soft decking and rotten studs or plates replaced with treated timber.
  5. Re-cover. The top in EPDM rubber with a fall to the front edge, the cheeks re-boarded and clad, or tile hanging renewed on new battens.
  6. Flash back into the roof. Lead soakers and step flashings at the abutment, dressed in and wedged.

Signs your dormer needs repair

  • A stain on a bedroom ceiling below the dormer
  • Water sitting on the dormer top after rain
  • Soft or rotten cheek boards
  • Hanging tiles slipped or missing
  • Lead at the junction lifted or sealed over with mastic
  • Draughts or damp around the dormer window

Dormer coverings and finishes

  • EPDM rubber top: One sheet with no joints, laid cold. Our standard for dormer tops. See EPDM rubber roofing.
  • GRP fibreglass top: A hard, jointless finish where the top is stood on for window cleaning or maintenance.
  • Tile or slate hanging: Matched to the main roof so the dormer does not stand out.
  • uPVC cladding: Low-maintenance cheeks and face, in white or grey.

How long it takes

Re-covering a dormer top is usually a day. Cheeks, hanging and flashings add one or two more, depending on access and scaffold.

What affects the price

  • Dormer size
  • Which parts need doing
  • Timber repairs found
  • Covering and cladding chosen
  • Scaffold

Typical flat top ranges are on our flat roof cost page. Yours is a fixed written price after the free inspection.

Aftercare

Look at the dormer top from an upstairs window each autumn. Leaves or water sitting on it are the early warning.

Denis was friendly and professional, clearly explaining the work. The new insulated roof, fascias, and guttering look incredible. The team were efficient and respectful throughout. Highly recommend All Pro Roofing & Guttering.

Common questions

Can a dormer be repaired or does it need rebuilding?

Most are repairable. Rebuilding is only needed where the structural timbers have gone, and we will show you photographs either way before you decide.

How long does a dormer roof take?

A flat top re-cover is usually a day, cheeks and flashings another one or two, depending on access and scaffold.

Will it match the rest of the roof?

We match tiles and hanging as closely as supply allows, and we will show you the match before we fix it.

Can you insulate a dormer while it is open?

Yes. Insulation goes into the top and cheeks while they are stripped, which makes a cold dormer bedroom noticeably warmer.

Do you need scaffold for a dormer?

On most houses, yes, because the work is at height on a slope. It goes on the quote from the start.
