Failed ridge mortar is the most common roofing maintenance issue across Ipswich's post-war estates. Lifting ridge tiles, crumbling bedding, loose hip caps — all need attention before a storm turns a maintenance job into an emergency. Free surveys across Ipswich and Suffolk.
Ridge mortar failure is the single most common roofing maintenance issue across Ipswich's post-war housing stock. On the concrete tile estates of Chantry, Whitehouse, Gainsborough and Castle Hill — properties built between 1955 and 1985 — the original cement bedding has been through 40–70 winters of freeze-thaw cycling. It has dried, cracked and in many cases is held in place only by gravity and the physical weight of the ridge tiles above it.
The failure mechanism is consistent: the bedding mortar dries and cracks within 20–30 years of installation. Moss and lichen growth on the ridge accelerates this by retaining moisture against the already-cracked surface, widening the cracks with each frost. Eventually the ridge tile rests on powder rather than mortar. In a sustained wind event, it shifts.
We use a dry fix system for most Ipswich ridge re-bedding work. Dry fix uses a flexible mortar that accommodates the thermal expansion and contraction that cement mortar cannot handle — which is the fundamental reason traditional ridge mortar fails. The ridge tile is mechanically clipped as well as bedded, providing additional security in wind. On period properties where lime mortar is the correct specification, we use lime bedding throughout.
Hip tiles are the angled tiles that run down the corners of a hipped roof. They use the same bedding system as ridge tiles and fail on a similar timescale. We check hip condition on every ridge survey visit and re-bed them at the same time where needed — it's cost-effective to do both while the scaffolding or ladder system is already in place.

"Ridge tiles were rocking — had been like it for a couple of years. Finally sorted. Dry flex mortar used, proper job. They also found a cracked ridge tile and replaced it. No unexpected extras on the final bill."
"Lime mortar ridge repoint on our period cottage. Right mortar specified without being asked. Neat work, good understanding of older properties. Would use again."
Ridge repointing on a standard 3-bed semi in Ipswich typically costs £300–£600 for the full ridge run. Hip tile rebedding adds £100–£250 per hip depending on length. Free survey, exact quote before starting.
Visible crumbling or missing mortar between ridge tiles, ridge tiles that rock or can be pressed down, mortar debris in the gutters below the ridge, or damp patches on the ceiling directly under the ridge line. Any of these indicate repointing is overdue.
In a storm, loose ridge tiles shift or come off completely. A single dislodged ridge tile exposes the ridge board and felt beneath to direct rain. Water ingress at the ridge then tracks down the sarking felt and appears as a leak on the ceiling below. What starts as a maintenance job becomes a weather emergency.
Well-executed ridge repointing with the correct mortar mix should last 15–25 years in Ipswich's climate. Properties in more exposed positions — elevated areas, west-facing ridges — may need attention at the lower end of this range. Moss growth on ridges accelerates mortar deterioration.
We use a dry flex mortar bedding system on most Ipswich re-bedding work — it accommodates thermal movement better than traditional cement mortar, which is the main reason traditional ridge pointing fails. Traditional sand and cement is still appropriate for lime mortar pointing on period properties.
Yes — and we recommend it. Hip tiles use the same bedding system as ridge tiles and fail on a similar timescale. If we're on the roof for ridge work, checking and re-bedding any hip sections that need attention at the same time is cost-effective.
If the ridge is the only issue and the tiles, underfelt and nails are in reasonable condition, repointing is the correct answer. If nail sickness is also present, we'll discuss both options honestly. A free survey tells you exactly which situation your roof is in.
