Green Roofs in Ireland

Green roof turns a flat roof into something living, a layer of sedum or wildflowers that looks good, helps wildlife, soaks up rainwater, and shields the roof underneath from the sun. The part that matters most is the watertight, root-proof base it all sits on, and that’s the bit we get right. Built by a family firm of roofers since 1969, across Dublin.

The types

What kind of green roof?

Green roofs run from a thin, easy layer of sedum to a full garden on the roof. The right one depends on the look you want, how much upkeep suits you, and what the structure can take.

Sedum (extensive)

The light, low-maintenance option. A shallow layer of drought-tolerant sedum plants that needs little care and suits most flat roofs and extensions.

Wildflower

Richer mix of native grasses and wildflowers for more colour and more visiting wildlife. A bit deeper, and a bit more looking after through the year.

Roof garden (intensive)

Deeper soil for shrubs, full planting beds, even a small lawn, in effect a real garden on the roof. It is heavy, so the structure has to be built for it.

What's included

Our green roof service

We build the roof a green roof needs, from the waterproofing up to the planting. The watertight, root-proof base is the roofing part, and the part that matters most. Each green roof job can cover:

  • Sedum, wildflower, and biodiverse green roofs on flat and low-pitch roofs across Dublin and beyond.
  • Extensions, garages, garden rooms, bin and bike stores, dormers, and larger commercial roofs alike.
  • Full build-up from waterproof membrane through protection, drainage, and filter layers to the planting.
  • Edge restraints, outlets, and inspection points, fitted so the roof drains properly and stays put.
  • Structural checks first every time, because a green roof is heavy and heavier again when it is wet.
  • Honest advice on the right type and the upkeep, including watering sedum through a long dry spell.

Most green roofs that fail were built on the wrong waterproofing, not the wrong plants. Ours start as proper flat roofs first. You get a written fixed price before any work, with workmanship cover behind it.

WHY GO GREEN

What A Green Roof Gives You

Green roofs are not just for looks, and most of what they give back you notice inside the building too.

Rainwater Held Back

The build-up soaks up rainfall and releases it slowly, easing the load on gutters and drains.

Cooler And Quieter

The growing layer insulates the room below, holding winter warmth, blocking summer heat, and softening rain noise.

Longer Roof Life

The planting shields the waterproofing from sun and frost, so the roof ages slower than a bare one.

Wildlife And The View

Bees and butterflies get a stop-off, and a bin store roof becomes something worth looking at.

What it costs

Green roof cost in Ireland

Green roofs cost more than a bare flat roof, because a full build-up and planting sit on top of the waterproofing. Some of that comes back, since the planting shields the waterproof layer and helps it last longer. Price comes down to a few things.

The type, since a light sedum roof costs least and a roof garden the most. Then the size, any structural work, and the access. Use our Roof Cost Calculator for a guide, then book a free survey for a fixed written price.

What affects the price

  • Type: sedum, wildflower or roof garden
  • Roof size and shape
  • Any structural strengthening needed
  • The waterproofing and build-up layers
  • Access and getting materials up

FAQS

Frequently Asked Questions

Direct answers from an experienced, hands-on roofing professional.

It’s a flat or low-pitch roof covered with living plants, usually sedum, growing on a built-up base of waterproofing, drainage, and growing medium. It looks good, helps wildlife, soaks up rainwater, and shields the roof underneath from the sun.

A green roof only works if the waterproofing under it is spot on, because a leak under soil and plants is hard to trace. That’s exactly why we put the time into the watertight, root-proof base before anything green goes on.

A green roof is heavy, more so when it’s wet, so the structure has to suit it. A light sedum roof is fine on many flat roofs, but a deeper roof garden needs a structure built for the weight. We check this before we recommend anything.

A sedum roof is low-maintenance: the odd weeding and a watering in a long dry spell. Wildflower and roof-garden types need a bit more attention. We’ll tell you straight what your roof will ask of you.
