Lead Flashing Under Roof Tiles

And in our experience when a single piece of flashing extends only a few inches under the shingles especially on a long roof slope and worse on a roof that happens to slope slightly towards rather than away from the abutting vertical building wall the accumulated roof drainage water near the bottom end of the roof wall intersection will.

Lead flashing under roof tiles.

Open valleys have metal flashing to protect this critical area of the roof. My builder had put some lead flashing on the roof to stop a water leak by the chimney but it kept leaking. Whilst roof tiles and slates are designed to keep out any rain there is always the chance that strong winds can lead to rain forcing its way through any gaps or underneath the tiles. Fixing damaged flashing should cost a similar amount to missing tiles roof flashing repair costs to replace a metre or so of flashing will cost between 100 and 250.

If working on a roof with profiled tiles lead dressing tools will need to be used to fit the lead flashing up and down across the valleys and troughs of the tiles.

Measuring lead roof flashing for a pitched roof if a pitched roof is abutting a wall there are three measurements required when cutting and bending the lead work. While some skylight manufacturers include flashing in their products sometimes roofing professionals have to create it or purchase it separately. However step flashings are used for slates and double overlapping flat profile tiles with accompanying lead soakers like the plain tiles pictured. Leak repair costs leaks are typically either the result of missing tiles or damaged flashing so the pricing of these fixes will depend on the nature of the leak.

Why does the lead have to go underneath the felt and not on top. Step flashings there are two distinct types of step flashing on a roof and getting them wrong can create leaks. The chase depth this is the amount of lead that will poke into the gap between brickwork normally a few mm short of bottoming out for ease of fitting. Step and cover flashings are mostly used for profiled tiles.
