Why upgrade to a warm roof in Enniskillen?
In a place like Enniskillen, homeowners usually think about insulation when the roof covering is worn out. That is the right moment, because the thermal rules normally apply to a replacement over a heated room, and adding insulation then costs far less than doing it separately later.
Around Enniskillen, flat roofs are common on low-rise post-war blocks of flats and on shops with flat-roofed rear stores below flats. Northern Ireland averages roughly 1,150 mm of rain a year, spread over many wet days, so a roof that sheds water quickly to clear outlets lasts far longer than one that holds puddles.

How long does a warm roof last?
The insulation in a warm roof should last for the life of the waterproofing above it, as long as it stays dry. Rigid PIR boards don't settle or slump in the way some loose insulation can.
The waterproofing is what sets the timescale. EPDM is typically quoted at 25 to 50 years, GRP at 20 to 40 years and modern torch-on felt at 15 to 25 years with good specification and care. A warm build-up also helps the deck, because keeping it warm and dry lowers the risk of condensation rot. If the waterproofing fails and water gets into the insulation, the wet boards should be replaced, so leaks need prompt attention. The lifespan guide compares the systems.
What's included?
- New waterproofing, with a written workmanship guarantee
- Rigid insulation boards sized to the U-value target
- Survey of the deck, joists and existing insulation
- Upstands, trims and kerbs reset to the new roof level
Building control in Northern Ireland
In Northern Ireland, Technical Booklet F1 sets roof insulation at 0.18 W/m²K when a roof over a heated room is renovated or newly built, where that's feasible. The district council's building control should be contacted before work starts, and we prepare the details it asks for. More on the rules.

How thick does flat roof insulation need to be?
It depends on the insulation product and the U-value target. With common PIR boards, meeting a renovation target usually means well over 100 mm. Thinner, higher-performance boards are available where height is tight.
