The mortar holding your ridge capping is the part of a tiled roof that gives out first, and coastal conditions bring that forward. Salt-laden air and constant wind work at the mortar joint, and the hot-then-wet cycle over summer opens hairline cracks that let water in behind the capping. Once that happens the bedding underneath softens, the capping starts to move, and what began as a cosmetic crack becomes a leak into the roof space. On exposed ridges facing the ocean this happens noticeably faster than it does inland.
We go along the ridges and hips and check the capping for cracking, movement and lifted sections.
We assess the condition of the existing mortar, since surface cracking and failed bedding are different problems with different fixes.
Where the bed underneath has broken down, the capping is lifted and re-bedded rather than pointed over the top of a failing base.
Flexible pointing is applied over sound bedding, which copes with the movement and temperature swings a coastal roof goes through.
Ridges, hips and the junctions between them are finished so water runs off rather than sitting in a joint.
We check the finished work over the whole roof before we pack up.
Call 0478 688 951 or send the form with your address and what you have noticed on the ridges.
We come out, inspect the capping and bedding, and give you a price before any work starts.
We complete the re-bedding and pointing, check the finished ridges and tidy up before we leave.
Pointing is the visible mortar along the edge of the ridge capping. Bedding is the mortar bed underneath that holds the capping in place. Pointing over failed bedding does not hold, so we assess both and tell you which one your roof actually needs.
The usual signs are visible cracking along the ridge line, small pieces of mortar in the gutters, capping that looks slightly out of line, or damp appearing in the roof space near a ridge after heavy rain.
Yes. Salt-laden air and constant wind work at the mortar joint, and exposed ocean-facing ridges tend to show cracking earlier than the same roof would inland.
Cracked or loose ridge capping only gets worse through a wet season. Call Vinnie and the local team on 0478 688 951 or send the form for a free on-site quote across the peninsula.

Australian standards and Code requirements we work to, with the source for each.
Any tiled roof pitched at less than 18 degrees has to have sarking underneath it, whatever the rafter or truss length. On older Sydney houses re-roofed before that rule bit, this is a common reason a tiled roof leaks in wind-driven rain.
AS 2050 governs how ridge and hip capping is bedded and pointed. Flexible pointing compound is what holds the capping as the roof moves; when it cracks and lets go, the capping lifts in wind and water tracks straight into the roof space.
AS 2050, the installation standard for concrete and terracotta roof tiles, applies to roofs pitched at 15 degrees or more. Below that the tile system falls outside the standard and a sheet metal profile is the compliant answer, not more bedding and pointing.

Quoting roof repointing in the Northern Beaches is not the same job as quoting it elsewhere in Sydney. Colorbond warranty asks for a six monthly wash: The standard warranty requires fresh water washing at least every six months of any roof area rain does not wash naturally, and does not cover failure… That is the kind of detail that changes the materials, the timing and the paperwork on a roof in Manly or the streets around it. Everything below links to the council or standard it comes from, so you can check it yourself.
The standard warranty requires fresh water washing at least every six months of any roof area rain does not wash naturally, and does not cover failure to replace corroded fasteners. On a coastal home that means eaves, awnings and wall abutments need washing deliberately.

Source: NSW Rural Fire ServiceBlueScope names Manly Beach as its metropolitan example of a surf marine environment, the harshest of its three salt classes under AS 4312. Wind, shelter and areas the rain never washes push the real corrosivity higher still, which is why the steel grade used here is not the one used inland.
Source: BlueScope Technical Bulletin TB-35 and AS 4312:2019Class 3 fasteners are only acceptable beyond 1km from marine influence. From 200m to 1km Class 4 is required, and inside 200m even Class 4 is not enough without checking with the supplier. Most of the ocean strip sits inside that band, so standard screws rust out long before the sheeting does.
