How many broken tiles is a repair, and when is the field finished?

A break is a path. A pattern of breaks is a diagnosis

Tiles crack from a heel, a dropped branch, a hailstone, a radio bracket, or a batten that has twisted and levered the nose. One crack lets wind-driven rain onto the sarking or, if there is no sarking, into the ceiling. That is a repair: the unit comes off, a matching unit goes on, and anyone already in the ceiling checks that the drip has not become a rotten batten. Roof Revival Melbourne writes that as a number of tiles and a plane, not as a mood.

The diagnosis changes when the breaks rhyme. Several noses gone along one course suggest the batten or the fixing, not bad luck. Star cracks clustered on the western plane after a storm suggest hail on a tile that may otherwise be hard. Crumbly breaks across every plane, including ones nobody walks, suggest the tile body has reached the end. The same word, “broken”, covers all three. The scope must not.

Counting without testing is how a twenty-tile repair is sold on a roof that will donate twenty more tiles next winter. Testing without counting is how a whole restore is sold for three hail cracks. You want both sentences on the quote.

Hard tiles can be swapped. Soft tiles multiply

A hard concrete or terracotta unit breaks clean. The neighbour beside it is still a roof tile. You can walk a careful path, replace the broken ones, and expect the field to remain. A soft concrete tile breaks dull. The nose powders. The next course is waiting to do the same because it was pressed in the same year and has weathered the same way. Every swap disturbs the neighbours. The repair creates the next repair.

That is the point where “how many” stops being the useful question. If a large share of the field is crumbling, an allowance of spare tiles is a delay. Replacement of the covering, and a look at battens while the roof is open, is the honest scope. If the crumbling is one bad batch on one plane and the other planes ring hard, the quote can be a plane, not a whole house. Roof Revival Melbourne will not average those into a single nervous number.

Terracotta adds a supply limit. You may have only eight broken clay tiles and still be unable to buy eight quiet matches. The field is not finished. The repair is constrained. That constraint belongs in the price as sourcing and placement, not as a reason to condemn sound clay. A concrete tile that is still in production is a simpler swap. Do not let the easy concrete assumption set the clay quote.

Where the breaks are changes the job

A crack in the middle of a plane wets the sarking under it. A crack in the first course at the eave can wet the fascia and the top of the wall. A broken hip cap is ridge work, not a field-tile swap, because the cap has to be seated, not just slid into a course. A tile broken around a valley has to meet the steel. Replacing the tile and leaving a rusted valley is a completed square on a leaking junction.

Ridges that have powdered will crack the starter tiles at the edge of the field over and over. If you only swap those cracked starters, you will be swapping them again. The bed is the cause. The count of broken field tiles, on that roof, is a symptom. A repair quote that includes the hip is the one that matches the mechanism. A repair quote that forever replaces the same two tiles is a subscription.

Hail, trades, and the breaks that are not old age

After hail, count chips and star cracks separately from tiles that were already soft. Insurance conversations like a schedule: plane, number, photo. Maintenance conversations like a body test. They can happen on the same week. They should not be blurred so that an old soft roof is described only as storm damage, or a fresh hail patch is used to sell a full replacement the rest of the field does not need.

Trades crack tiles too. Aerials, solar, painters, and anyone who crossed the roof for a flue can leave a line of breaks and no confession. If the breaks follow a path from the ladder to a fitting, say so. The tiles may be hard. The repair is still real. Future access needs a method so the next trade does not add a second line. Roof Revival Melbourne notes that path. We do not need a story about whose boot it was in order to fix the units.

What an allowance is for

On a restoration, a broken-tile allowance is a number of spares for units that fail as the roof is worked, plus the ones already cracked. It is not a promise that every future crack for a decade is free, and it is not a bin of tiles large enough to quietly re-cover a soft field. If the allowance in two competing quotes differs wildly, ask what each person saw. One of them may have seen three cracks. The other may have seen a crumbling plane and tried to stuff it into a repair line.

Ask for the count, the profile, and the body test in writing. Ask what happens if matching tiles cannot be found. Ask whether sarking under the worst leaks is torn. A repair that names those items is comparable. A repair that says “tiles as required” will become a different number on the day, always in one direction.

When to stop counting and change the job

Stop treating it as a repair when the tiles cannot be handled without more of them failing, when noses are gone across a plane, or when the battens under the breaks are no longer a fixing. Stay with a repair when the field is hard, the matches exist, and the ridges and valleys are either sound or written as their own lines. Send photos of the breaks, a photo of a snapped edge if a piece is on the ground, the suburb and the storeys.

The number is a quantity. The body is the decision. Roof Revival Melbourne will count both, and will say when the honest quote is a listed repair rather than a new roof wearing a small-job price.
