Roofs and flat roofs
One concrete tile lying in the gutter has split into layers. Does that single tile mean the covering has reached the end of its life?
No single concrete tile that has split into layers in the gutter means the covering has reached the end of its life. Delamination of one tile is that tile. A unit can part in layers while the rest of the slope stays intact. The visit does not give the covering a lifespan, and it does not condemn every course because one failed tile is lying in the gutter. Deal with the tile in front of you. Do not invent a remainder of life the report never stated.

What is the fuller explanation?
A tile in the gutter is useful evidence. It came from somewhere, and its split faces can be seen. It is still one unit. The surveyor has not declared a batch failed and has not said the underfelt is exhausted. Look for the gap it left, if one was seen, and keep that place in the note. End of life is a phrase this single layered tile does not earn.
Ask a roofer to find the gap, match the tile if they can, and price a local replacement, including any clip or nail that unit needs. If they propose stripping the slope, ask which other tiles were seen delaminating. Without that list, a whole-slope figure is not the answer to one layered tile in the gutter. Do not accept a life in years as though the report had given one.
What should you ask your surveyor?
- Was only one delaminated tile seen, or were others on the slope parting the same way?
- Did you find the gap that tile left, or only the piece lying in the gutter?
- Are you rating that one tile, or the covering as a whole?
What are the typical next steps?
- Keep the gutter tile until a roofer has seen the split layers.
- Ask for a price to replace the failed unit and to find its gap.
- Do not treat a whole-slope quotation as the meaning of this note.
Costs vary with the building and with who you instruct. Where this page does not cite a published figure, ask the surveyor, a relevant specialist, or your solicitor for a written quote. Do not treat a forum average as the price.
Also asked about this
Does one layered tile date the rest of the covering?
No. The report does not give the tiles a life in years. One delaminated unit in the gutter is not an age for every course on the slope.
Should the underfelt be replaced because that tile split?
Not on this note alone. The defect described is the concrete tile that split into layers. The underfelt was not given that verdict.
