Is It Better to Repair an Old Roof or Replace It in Hotwells?

Neither repair nor replacement is always right. The answer depends on what is failing and how widely. Here is how we judge it on older Hotwells roofs and what to ask.

Old roofs are rarely all good or all bad. A Georgian or Victorian terrace may have sound slate with failing lead, or tired felt under good coverings. In Hotwells, exposure on the gorge side, parapets and awkward access add their own pressures. The question is where the faults are and whether repair will hold.

When repair makes sense

Repair works when the problem is local and the rest is sound: a few slipped slates, a split in the lead, a failed ridge section, a blocked parapet gutter. Fixing the cause restores the roof, and it costs less disruption than a full job. We say so when this is the case, and we do not push for a bigger job than the roof needs.

Old lead can often be renewed in sections, and slipped slates re-fixed or swapped for matching ones, so a roof that looks tired may have plenty left in it once the weak spots are dealt with. Sound material is kept and reused wherever it is worth keeping, and we show you what we have found before suggesting anything bigger.

When replacement is the honest answer

If failures are spread across the roof, replacement tends to be sounder. That might mean slates slipping everywhere because the nails have corroded, felt that is torn or perished across a slope, or timbers that are rotten in many places. Repairing one spot at a time on that kind of roof can mean chasing leaks around the house, with access needed each time.

• Fixings failing across a whole slope
• Underlay torn or perished widely
• Timbers rotten in several places
• Repeated repairs in the same area
• Water getting in at several points

What we look at

We check from the loft and from outside: the covering, the underlay, the battens and rafters, lead flashings, valleys, parapet gutters, chimneys and gutters. We photograph what we find so you can see it for yourself. On an old roof, one fault often points to another. A stained rafter in the loft may lead us to a lead flashing we could not see from below.

Older roofs, careful judgement

On terraces and exposed slopes, partial replacement is often possible: re-covering one slope or reworking a section of lead without redoing the whole house. We look at what is practical, including how scaffolding sits on steep streets. Where material is worth reusing, such as sound slates, we say so.

Whatever the route, the roof is left weathertight at the end of each day, and we explain how that is managed on tight terraces where neighbours are close by. Where scaffolding is needed, we agree its position and timing with you first, since street space is tight and neighbours need notice.

Questions to ask

Ask the roofer to explain what is failing, what each option achieves and what happens if you wait. Ask for a written description of the work and how hidden problems will be handled. Larger work may need planning or Building Regulations checks — we advise before work starts.

Ask too how long the access equipment will be on the street, and what they will do if the weather changes halfway through. Straight answers to practical questions are a good sign. A roofer who has thought this through will answer without hesitation, and will put the details on paper for you to keep.
