Why garage roofs fail

Felt goes brittle, splits at the laps and lifts at the edges. Water then sits on the sagging deck instead of running off, and the ponding finishes the job. Replacing the covering without fixing the falls just buys a couple of years. If the deck is still firm, flat roof repairs can buy the roof more years for less.

What we do

Strip to the deck, replace the boards that have gone, add firrings so there is a proper fall, then bond the new covering down and finish the edges with drip trims into the gutter.

Insulated garage roofs

If the garage is a workshop, a gym or a room now, we can build insulation into the deck at the same time. It costs less to do it while the roof is open than to come back for it.

What is included

  • EPDM rubber or fibreglass
  • Rotten decking replaced
  • Falls built in so water drains
  • New drip trims and outlets
  • Most garages done in a day
  • Insulation option while the roof is open

How a garage roof is replaced

  1. Clear and protect. We ask you to clear the space under the roof, and sheet what cannot be moved.
  2. Strip. Old felt and chippings removed and taken away.
  3. Deck and falls. Soft boards replaced, firrings set so water drains to the gutter, insulation added if requested.
  4. New covering. EPDM rubber bonded in one sheet or a GRP fibreglass finish.
  5. Trims and gutter. New drip trims and the gutter refixed or replaced so the water leaves the roof.
  6. Photographs and sign-off. Before, during and after photographs, including the deck we found when the old felt came off.

Signs your garage roof needs replacing

  • Water inside the garage after rain
  • Felt cracked, blistered or bare
  • Sagging between the joists
  • Puddles that sit on the roof for days
  • Edge trims rotten or missing
  • Moss and weeds growing on the roof

Garage roof options

  • EPDM rubber: Our usual choice for garages. One sheet, laid cold, no joints across the roof.
  • GRP fibreglass: A hard finish if you want a colour or the roof is walked on.
  • Insulated deck: For garages used as gyms, workshops or rooms.
  • Rooflight: A kerbed rooflight added while the deck is open, for light in a workshop or gym.

How long it takes

A single garage is usually one day. A double or a garage with a soft deck can take two.

What affects the price

  • Garage size
  • Deck condition
  • Insulation
  • Trims and gutter
  • Waste removal

See typical ranges on our flat roof cost page.

Aftercare

Keep leaves off the roof and the gutter clear. Do not stand ladders on the new covering.

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

How much is a new garage roof?

It depends on the size and whether the decking has gone. We measure, tell you what the deck is like and give you a fixed written figure.

Can you do it without taking the old one off?

We do not recommend it. Covering wet, sagging boards traps the problem and the new covering follows the old shape, including the puddle.

Do you replace asbestos garage roofs?

Not the asbestos itself, that needs a licensed contractor. We will point you at one and take on the new covering once it has gone.

Does a garage roof replacement need planning permission?

Not for a like-for-like covering on an existing garage. Changing the height or shape can, and we tell you before quoting if that applies.

Can you do a shared garage roof in a block?

Yes, one garage or the whole block. We photograph the junction with the neighbouring roof before and after.

How long does a rubber garage roof last?

EPDM laid on a sound deck with a proper fall is a long-life covering, far beyond felt. The manufacturer's position comes in writing with your quote.
