Ridges and flashings are the two details that let water into tall Victorian and Edwardian roofs. This is what each repair involves, step by step, and what we look for first.
The large villas of Sneyd Park have long ridges, high chimneys and plenty of valleys and abutments, all exposed to wind from the gorge side. Those are exactly the places where bedding mortar cracks and lead lifts. Repairing them properly is skilled, careful work, and it helps to know what should happen on your roof before anyone starts.
Why ridges loosen
Ridge tiles sit along the highest line of the roof, held by mortar or fixings. Wind works at them constantly, and temperature swings crack the bedding. Once a section is loose, water gets under the tiles and wets the timbers, and a strong gust can lift a piece completely. On a tall house that is a real risk to anyone below.
- Cracks or gaps in the line of bedding mortar
- Ridge tiles sitting out of line or tilted
- Mortar crumbs found in gutters or on the ground
- Daylight visible along the ridge from the loft
What re-bedding involves
We take off the loose ridge or hip tiles, clear the old mortar and check the state of the timber and felt beneath. The tiles are then re-laid on fresh bedding and pointed, or fixed with a dry ridge system where it suits the roof. Hips and the junction at the top of each slope get the same careful treatment.
What lead flashing does
Flashing is the strip of lead that seals the join where the roof meets a chimney, wall, dormer or valley. It is dressed tight into the joint and sealed at the top edge. On big villa roofs with several chimneys and valleys, there are many such joins, and every one is a place where water can find its way in.
How a flashing is repaired
Where lead has lifted, split or pulled out of its joint, we look at the cause before touching it, since the pointing, the wall or the chimney may also be failing. A small split can sometimes be repaired. Widespread cracking or slippage usually means new lead, dressed properly and fixed to hold. Poor patching with sealant is not a repair.
Pointing around flashings is checked at the same time, because a well-dressed lead strip is only as good as the joint that holds it. If the chimney brickwork or the wall behind is crumbling, that needs attention first, otherwise the new lead will simply fail in the same place.
Access and what to ask
Tall roofs on sloping gardens need proper access, planned before the day. Ask how the roof will be reached, what will be done about debris and the garden below, and for a plain description of the repair. Expect the work to be explained, photos or a clear account of what was found, and a tidy site when the job ends.
Frequently Asked Questions
Can ridge tiles be fixed without replacing the whole roof?
Usually yes. If the tiles beneath are sound, the ridge can be re-bedded or refixed on its own. We check the timber and felt under the ridge, and tell you honestly if the wider roof also needs work.
How do I know if a flashing is failing?
Look for stains on the ceiling or wall near a chimney, dormer or valley, and for lifted or gapped lead from the ground. A damp patch beside a chimney breast is a typical sign. Call us for a proper look rather than guessing.
Does lead flashing need replacing completely?
Not always. A small split or a short lifted section can sometimes be repaired. If the lead is cracked in many places or has slipped in its joint, new flashing gives a better result than patching.
