Ridges and flashings are the joints of a roof, and joints are where weather wins first. Here is what a proper repair to each involves on older Arnos Vale homes.
Ridge tiles run along the top of the roof and lead flashings seal the places where the roof meets something else, such as a chimney or a wall. Both work hard and both age. On the older stone and brick houses of Arnos Vale, with exposed gables and steep slopes, they are some of the first places we look when someone reports a leak or a loose tile.
Where the ridge and the flashings sit
The ridge is the line along the top where two slopes meet, covered by a row of capping tiles bedded on mortar or fixed dry. Flashings are strips of lead dressed into the brickwork or stonework and over the tiles, so water runs off rather than behind. Valleys are the lead or tile channels where two roof planes meet. On a Victorian villa there can be a surprising number of these junctions.
How a ridge repair is carried out
Loose or cracked ridge tiles are lifted, the old crumbling mortar is cleared out, and the tiles are bedded again on fresh material, with any broken ones replaced. Where the ridge has failed along most of its length, re-bedding the whole run is more sensible than patching. Because the ridge sits at the highest, windiest point, we check the end tiles and the hips at the same visit.
How lead flashing is repaired
Lead can lift, split or pull away from the wall as the mortar line behind it weakens. A small tear may be repaired, but often the better answer is to renew the affected length and dress it properly into a chased joint, so the new work is secure. We look at the tiles and the brickwork around it as well, because a flashing is only as good as what holds it.
- Check the mortar joint the lead is tucked into
- Look for splits at corners and folds
- Make sure the lead overlaps the tiles properly
- Clear debris from valleys and back gutters
What we look for before quoting the job
A good assessment covers more than the one spot you noticed. From the ground we check for slipped tiles and a sagging ridge line, and inside the loft we look for stains near chimneys and party walls. Then we inspect the roof and explain which faults are urgent and which can wait, so you are not paying for repairs you do not yet need.
Questions worth asking any roofer
Ask for a written description of exactly which ridge lengths and flashings will be dealt with, and how access will be arranged. Ask what the old material looked like once removed, and whether photographs can be shared. A roofer who explains the work plainly and leaves the site tidy is doing the job properly. Some alterations to a roof may need planning or Building Regulations checks, and we advise before work starts.
- A written description of the work and materials
- How access and any scaffold will be arranged
- Photographs of the problem and the finished repair
Frequently Asked Questions
How do I know my ridge needs attention?
From the ground you may see tiles out of line, gaps at the top of the roof, or pieces of mortar in the gutter or on the path. None of that proves a leak, but it is a good reason to ask for a proper look.
Is lead flashing always replaced rather than repaired?
No. A small, sound tear or lifted edge can sometimes be repaired. When the lead is split in several places, thin or no longer sits securely, renewing that length is more reliable, and we explain which applies when we have seen it.
Can both jobs be done in one visit?
Often yes, particularly when both are small. Larger runs of ridge re-bedding or several flashings may need more than one visit, and weather decides what is safe. We will tell you what to expect before starting.
