ROOFING QUESTIONS & ANSWERS
Everything you need to know about planning permissions, building regulations, flat roof membrane comparisons, and our guarantee terms.
Planning, Compliance & Guarantees
In most cases across England, replacing an existing roof does not require planning permission provided the roof line isn't raised significantly and similar materials are used. However, if your home is in a Conservation Area (such as parts of St Albans, Hertford, or Colchester) or is a Listed Building, specific slate or tile approvals may be required. We assist with all local planning queries.
Yes. Under UK Building Regulations Part L, if more than 25% of a roof is replaced, the thermal insulation must be upgraded to modern energy efficiency targets. We ensure proper insulation thickness and ventilation gaps, and provide the relevant sign-off documentation upon completion.
Yes. Our 10-year workmanship guarantees are provided in writing and remain fully attached to the property. They can be transferred to new buyers if you decide to sell your home.
Flat Roofing Choices (EPDM vs GRP Fibreglass vs Felt)
EPDM is a synthetic rubber laid in single seamless sheets, providing extreme UV and temperature flexibility with a 50+ year lifespan. GRP (Glass Reinforced Plastic) is a liquid-applied fibreglass resin system cured on site, forming a rock-hard, jointless surface that resists heavy foot traffic and is ideal for balconies and domestic extensions.
GRP flat roofs can be specified with a non-slip textured finish suitable for maintenance access or balcony usage. EPDM is tough and withstands occasional maintenance foot traffic, but is not designed for continuous patio deck use without protective walkway tiles.
A typical single or double garage or kitchen extension flat roof (15m² to 40m²) usually takes 1 to 2 working days, assuming dry weather conditions during membrane curing.
Site Working Conditions & Weather Delays
We plan each day around strict local Met Office meteorological forecasts. We only strip sections that can be quickly dried-in with heavy-duty breathable membrane before rain arrives. In addition, our team always carries industrial water-tight tarpaulins to completely seal any exposed sections in seconds.
No, as long as we have outdoor power access and clear access around the perimeter of your building, you don't need to stay home. We communicate daily progress via text messages and evening phone check-ins.
We lay thick plywood sheets over driveways to prevent skip wheel indentation, place ground tarps over lawns and flowerbeds to catch debris, and run a heavy-duty magnetic roller across paths and gravel daily to gather loose copper and steel nails.
