FAQs
What damage can Bristol’s frequent driving rain cause to my roof?
Persistent heavy rain can loosen or dislodge slates and tiles, wash away protective mineral surfaces on asphalt shingles, accelerate corrosion of flashings, and drive moisture under under-lays and into roof timbers. Left unchecked, these issues lead to leaks, damp insulation, timber rot, mould growth, and even structural weakening of rafters. A timely inspection after protracted wet spells is the best way to spot rain-related problems before they necessitate a full replacement.
How can I tell whether my roof needs replacing rather than just repairing?
Key warning signs include: 1) repeated leaks in different areas, 2) widespread moss, lichen or algae indicating long-term moisture retention, 3) sagging or uneven roof lines, 4) more than 25–30% of tiles/slates missing, cracked or delaminated, 5) daylight visible in the loft, 6) under-lay that has become brittle or torn, and 7) your roof being over 20–25 years old (or 50+ years for natural slate). If several of these symptoms are present, a full replacement is generally more cost-effective and longer-lasting than piecemeal repairs.
Which roofing materials stand up best to Bristol’s wet, windy climate?
For most domestic properties we recommend: • Natural Welsh or Spanish slate for period homes—exceptional durability (80–100 years) and low water absorption. • High-quality concrete tiles with deep interlocking profiles—excellent wind uplift resistance and lower cost than slate. • Fibre-cement slates for a lightweight, budget-friendly alternative with good rain shedding. • For flat or low-pitch roofs, a fleece-backed single-ply membrane (EPDM or PVC) or a warm-deck liquid waterproofing system provides seamless, ponding-resistant protection. We will discuss aesthetics, budget, roof pitch, and long-term maintenance with you to choose the best option.
Can you undertake a roof replacement during Bristol’s rainy seasons?
Yes. With proper planning and weather monitoring, we carry out replacements year-round. We only strip as much roof as we can make watertight the same day, and we use breathable temporary coverings and scaffold sheeting to shield open areas from sudden showers. If heavy rain is forecast all day we reschedule the stripping portion and focus on off-site fabrication or ancillary tasks to keep the project on schedule without risking water ingress.
How long does a full roof replacement take and will my home be exposed to the weather?
A typical three-bedroom semi-detached house takes 4–6 working days for a pitched roof and 2–3 days for a straightforward flat roof, assuming no structural timber repairs are needed. We erect edge protection and dust sheets on day one, then remove old coverings in sections, install new breathable membrane and battens the same day, and finish with tiles, slates or membranes. Your loft interior is never left exposed overnight; each stage is weather-proofed before we leave site, so your home remains dry throughout the process.
Do I need planning permission or Building Regulations approval in Bristol for a roof replacement?
Most like-for-like roof replacements fall under Permitted Development and do not require planning permission. However, consent is needed if you live in a Conservation Area, your home is Listed, or you are significantly altering the roof’s profile or height. Regardless of planning status, all roof replacements must comply with Part L and Part A of the Building Regulations. We notify Bristol City Council’s Building Control on your behalf, arrange inspections, and provide the final compliance certificate (or Competent Roofer self-certification) once the work is complete.
