FAQs
What are the most common issues you see with flat roofs in Bristol?
In Bristol we frequently encounter ponding water, membrane blistering, and cracked or slipping flashings. The city’s frequent rainfall and occasional high winds can accelerate wear on older felt or asphalt roofs, leading to leaks around roof penetrations and parapet walls. Regular inspections help spot these issues early before major water ingress occurs.
How do I know whether my flat roof needs a repair or a full replacement?
A thorough survey looks at the age of the covering, the extent of saturated insulation, and the condition of the deck. If damage is localised—such as a single puncture or failed seam—a targeted repair is usually enough. However, if over 25-30 % of the roof is water-logged, the membrane is near the end of its service life, or the deck shows rot or corrosion, a full strip and re-roof is more cost-effective long-term.
Which flat-roof materials do you recommend for Bristol’s climate?
For reliability and longevity we suggest: (1) High-performance torch-on felt with mineral cap sheet (lifespan 20-25 years); (2) Single-ply PVC or TPO membranes, which cope well with standing water and allow heat-welded seams; (3) GRP (fibreglass) systems that create a seamless, fully bonded surface ideal for smaller roofs and dormers. All three handle Bristol’s wet conditions well, but choice depends on budget, roof size, and foot traffic.
Will I need planning permission or building control sign-off for a flat-roof refurbishment?
Planning permission is rarely required if you’re simply replacing the covering like-for-like. However, under Part L of the Building Regulations, upgrading the roof typically triggers a requirement to improve thermal performance. We liaise with Bristol City Council’s Building Control to ensure new insulation meets the current 0.18 W/m²K U-value, and we provide all certification on completion.
How long does a typical flat-roof repair or replacement take?
Small patch repairs can be completed in half a day. A full replacement on a single-garage roof (≈20 m²) usually takes 1–2 days, while larger commercial roofs (200 m²+) may require a week or more depending on weather and substrate drying times. We give a detailed programme before work starts and use temporary coverings to keep your property watertight between stages.
What kind of warranty do you provide on flat-roof works?
All repairs come with a labour and materials guarantee of 12 months. Full re-roofs are backed by a 10-, 15-, or 20-year warranty depending on the system installed. We are approved installers for major manufacturers, so you receive both our workmanship guarantee and the manufacturer’s material warranty, giving double protection against leaks or premature failure.
