Roof repairs in Orpington
Slipped tiles, valleys, flashings, ridge and hip. We find where the water is getting in, not just where it is coming out.

Where water actually gets in
A leak almost never shows where it starts. Water gets past the covering, runs down the felt and along a batten, and drips off somewhere else entirely. These are the places it usually starts, and what each one looks like from inside the house.
Valleys
Where two slopes meet. The valley carries more water than any other part of the roof, and moss and leaves collect in it. From inside: a damp line on the ceiling under the join of two roofs, worse in heavy rain than in drizzle. The roof above has ferns growing out of its valley.
Flashings
The lead where the roof meets a chimney or a wall. Lead lifts, cracks along the fold, or the mortar holding it in the joint falls out. From inside: damp beside the chimney breast, a tide mark on the chimney in the loft.
Ridge and hip
The tiles along the top and down the corners. Old ones are bedded on mortar, and mortar cracks. From inside: bits of mortar in the gutter, a tile that rattles in the wind, damp along the top of an outside wall.
Slipped and broken tiles
Nails rust through, a tile slips, frost breaks one. From inside: daylight through the loft, or a wet patch that moves around because the gap is above a batten and the water runs before it drops.
The eaves
The bottom edge of the felt goes brittle first, because it gets wet and dry and wet again. Water runs down the felt and drops behind the gutter. From inside: damp above a window head, staining on the fascia outside. This is the one most often blamed on the gutter.
What we do when we come
We get up and look. Not from the pavement and not from a drone. We photograph what we find, show you, and tell you in writing whether it is a repair or the start of a re-roof. If it is a repair, we do it with matching tile where we can get it, and we tell you where we could not.
A repair is the right answer for a roof that is basically sound with one thing wrong with it. It is the wrong answer for a roof that is failing in three places at once, and we will say so rather than take the smaller job three times.
Moss
Moss on the courses holds water against the tile and, when it comes off in a storm, blocks the gutter. Clearing it is part of most repairs. It is worth knowing that a roof with heavy moss on the north slope and none on the south is a normal roof, not a failing one.

One that went past repair
Moss and lichen right across the courses on both pitches. This one was not a repair, and we said so before we quoted it.


Where we do it
Most repairs are a single visit once we have looked. Where scaffold is needed we say so on the quote, and we do not put it up for a job that can be done safely from a ladder or a tower.
