Luke came by with his boy John for our work. Didn't hesitate climbing the roof inspite of the bad weather. Very good roofer. Repaired my decades old gutters, tiles and general roof repairs very well. Very experienced, would highly recommendPosted on Google![]()

Contacted for an emergency roof leak and following the call Luke arrived in under 30 mins and got straight into finding the cause. Once cause was identified he explained everything and explained how he was going to remedy the leak. Luke carried out a full inspection and waited a while to ensure everything was in order and once I was happy that when he left.Posted on Google![]()

Got a roofing inspection done following a survey when buying our house. Luke has been exceptional in both his communication and attention to detail. He kept us appraised the full time, and explained key parts to us in detail. His breakdown of what needed to be done was clear and covered off only the bits that actually needed attention. Very friendly and honest, it’s been a great experience with him, would definitely recommend him!
How to Protect Flat Roofs From Standing Water
Maxwell’s Roofing (family-owned, owner-led) specialises in flat roofs across Milton Keynes and nearby towns. If water still sits on your flat roof 24–48 hours after rain, it can lead to leaks, early membrane failure, and structural issues. This guide explains causes, fixes, prevention, regulations, costs, and when to call a pro. 80+ 5-star Checkatrade reviews and only 5-star Google reviews. Call 07311091804 or email sa***@*****************ng.uk.
Key points at a glance
- What ponding is: Water that remains on a flat roof 48+ hours after dry weather.
- Main causes: Insufficient falls, blocked outlets/gutters, deck deflection, poor detailing, too few/poorly placed outlets, heavy surface loads.
- Risks: Faster membrane wear, higher leak risk, added loading (1,000 litres = 1 tonne), freeze–thaw damage, moss/algae growth.
How we fix ponding on existing roofs
- Maintenance: Clear outlets/scuppers/gutters, fit leaf guards, re-seal penetrations, add walkway tiles.
- Drainage upgrades: Add outlets or parapet scuppers; fit overflow weirs; resize/reposition downpipes and hoppers to BS EN 12056 principles.
- Create falls: Tapered insulation (design 1:40 to achieve ≥1:80 in use), crickets/local screeds, or re-decking if sagging is severe.
- Membranes (paired with drainage improvements): EPDM, GRP, reinforced bitumen membrane (felt), or liquid systems.
- Critical details: Upstands at 150 mm above finished level, correct edge trims/drips, proprietary collars at penetrations, material compatibility. Safety-first, fully insured.
Preventing ponding on new/replacement roofs
- Design: 1:40 design falls, adequate outlet density/placement with secondary overflows, avoid flat “pans” with crickets/sumps.
- Warm vs cold roofs: Warm roofs with a VCL preferred; cold roofs need meticulous cross-ventilation.
- Structure: Check loadings and deflection (Part A); specify spans/joists to limit sagging.
- Detailing: 150 mm rooflight kerbs; parapet weeps/overflows; group penetrations.
Regulations and standards
- We work to Parts A (Structure), B (Fire—e.g., Broof(t4)), C (Moisture), F (Ventilation), L (Energy).
- Building Control is typically required when refurbishing/replacing more than 25% of a roof or changing structure.
- Installations follow manufacturer guidance and British Standards (e.g., BS 6229, BS 8217).
When to book an inspection
- Puddles remain 48+ hours, interior staining, cracking/blistering/lifting, moss/algae, debris/overflowing gutters, or storm disturbance. Same/next-day call-outs across Milton Keynes, Stony Stratford, Newport Pagnell, Bletchley, Great Linford, Bradwell, Northampton, Bedford, and Luton.
Services
- Leak tracing/repairs (EPDM, GRP, felt, liquid)
- Tapered insulation schemes
- Drainage upgrades (outlets, scuppers, overflow weirs)
- Full flat roof replacements
- Skylight/rooflight installation
- Gutter cleaning/repairs/replacements
- Drone/visual inspections with photos and reports
Local case study: Newport Pagnell
- Issue: Undersized outlet, no falls, sagging deck.
- Solution: Tapered insulation (1:40) to two new internal outlets, single-piece EPDM with sumps, rebuild rooflight kerbs to 150 mm, add parapet overflow.
- Result: No ponding after heavy rain; damp resolved; better thermal performance.
Typical costs and timescales
- Clean/minor outlet works: from £180–£450
- New outlet/scupper with detailing: from
