Hotmelt roofing is a seamless waterproofing system where a two-layer modified bituminous rubber compound is applied as a hot liquid directly onto a prepared roof deck, forming a fully bonded and jointless membrane with a typical depth of 6mm. This method is highly effective for building roofs, podium decks, and heavy use balconies.
The installation of hotmelt flat roof Ireland systems provides total bonding to the deck, which removes the risk of water tracking under the surface. In the event of a physical puncture, the damage is localized and easy to isolate. This makes hotmelt a popular specification for large municipal and commercial properties.
Constructors.ie connects homeowners across Ireland with verified hotmelt roofing contractors in Dublin, Cork, Galway, Limerick, Waterford, and nationwide. Vetted local professionals ensure the hot melt rubber is heated and spread precisely to meet manufacturers standards.
The difference between hotmelt roofing and single ply roofing is that hotmelt is poured as a hot liquid to form a seamless barrier, whereas single ply uses manufactured sheets welded together at the seams. While single ply is lighter and cheaper for small extensions, hotmelt roofing vs single ply comparisons show that hotmelt provides better security for zero fall roof designs. This system is ideal for flat roofs that may experience ponding water.
Liquid application eliminates overlaps, welds, and joints where traditional roofing membranes usually fail first.
The rubberized bitumen compound remains flexible throughout its lifespan, allowing minor surface damage to seal itself.
Since the compound bonds directly to the deck, water cannot flow laterally beneath the membrane in the event of a leak.

The concrete or steel roof deck is thoroughly cleaned, dried, primed, and checked for any surface defects.
Bituminous rubberized blocks are heated in a specialized boiler to 180 degrees. The liquid is poured and trowelled onto the deck.
A high-strength polyester reinforcement fleece is embedded directly into the hot first layer to increase tear resistance.
A second layer of hot liquid is applied. This is immediately topped with a durable protection sheet or quartz sand layer.

Hotmelt roofing is a seamless waterproofing system where a two-layer modified bituminous rubber compound is applied as a hot liquid directly onto a prepared roof deck, forming a fully bonded and jointless membrane with a typical depth of 6mm.
A correctly specified and installed hotmelt roofing system has a life expectancy of 25 years or more. Many manufacturers offer insurance-backed guarantees of 20-25 years. It outperforms torch on felt and single ply in terms of long-term waterproofing integrity on zero-fall and inverted roof applications.
Hotmelt roofing creates a seamless, fully bonded membrane with no joints or seams. Single ply roofing uses a single sheet of membrane fixed or ballasted to the deck. Hotmelt is better suited to complex detailing, zero-fall roofs, and podium decks. Single ply is typically faster to install and lower cost on straightforward flat roofs.
Yes. Hotmelt roofing is used on domestic extensions, flat-roof garages, and house extensions across Ireland as well as on commercial and industrial buildings. It is particularly suitable where the roof has a zero or very low fall where ponding water is a risk.
