“They came out the same day, found the problem straight away and had it fixed before the rain came back. Honest price and very tidy. Highly recommended.”

Flat Roofs in Hightown — The Right System for a Coastal Village
Hightown’s coastal position makes the choice of flat roofing system more consequential than in a sheltered inland location. Traditional bitumen felt is the least suitable option for this environment — UV exposure, thermal cycling and the physical movement caused by high winds all accelerate felt degradation, and in a location as exposed as Hightown that degradation happens faster than elsewhere. Modern systems are a significantly better choice.
For flat roofs in Hightown we recommend GRP fibreglass or EPDM rubber as a matter of course. Both systems are seamless and single-membrane, eliminating the joint and overlap failures that are the most common mode of failure on traditional felt. GRP is our most commonly installed system for garage roofs, bay tops and small extensions; EPDM is our recommendation for larger flat roof areas where the rubber membrane’s flexibility and thermal resilience are particularly relevant.
Because we are based in adjacent Formby, we are as close to Hightown as any roofer can be. We cover the village for both emergency flat roof repairs and planned installations, and our familiarity with the local properties and their specific exposure means we know what to expect when we arrive.
Every flat roof installation in Hightown is preceded by an inspection of the existing deck. Coastal properties are particularly susceptible to deck damage from long-standing water ingress, and installing a new membrane over a compromised substrate is a false economy. We report what we find honestly before any work begins.

Building Regulations
Building Regs, U-Values & Warm Roof Upgrades
Current Building Regulations (Approved Document L) target a flat roof U-value of around 0.16–0.18 W/m²K. A full replacement covering more than 50% of the roof typically triggers this requirement — which means most flat roof replacements are also a genuine opportunity to properly insulate the roof, often for the first time. We build every full replacement to a warm roof specification (insulation above the deck) as standard, since it's now the recommended approach and largely eliminates the condensation risk that older cold roof designs carry. See our complete guide to Building Regs and warm roof upgrades for the full detail.
Common questions
Flat Roofs — What People Ask
Why does felt flat roofing fail quickly in Hightown?
The coastal position means higher UV exposure, greater thermal cycling and wind uplift that stresses edge details and seams. Traditional felt relies on overlapping seals that are vulnerable to these stresses; modern GRP and EPDM systems are not.
What system do you recommend for a Hightown garage roof?
GRP fibreglass for most applications. It is a seamless, hard-wearing system that handles the coastal conditions well and requires very little maintenance over its 25+ year lifespan.
How quickly can you attend for a flat roof repair in Hightown?
Same day for genuine emergencies — we are based in adjacent Formby. For planned repairs and installations, call 07596 884288 to arrange a survey.
Is GRP fibreglass suitable for a flat roof in a very exposed location?
Yes. GRP is one of the most robust flat roofing systems available and performs well in exposed coastal locations. Its seamless, chemically bonded surface has no joints to fail and handles wind uplift better than traditional felt.
Does a flat roof replacement need to meet Building Regulations?
Yes, in most cases. A full replacement covering more than 50% of the roof is treated as a thermal element upgrade under Approved Document L, targeting a U-value of around 0.16-0.18 W/m²K. We build every full replacement to this standard, using warm roof construction, as a matter of course.
