Roof get a lot of leaves on it. There are four drainage outlets, draining to four downpipes inside the house. The gulleys go unswept for years due to lack of roof access.
The roof structure, from inside up, is joists, chunky battens, c75mm of wood wool, concrete, OSB-PIR board and GRP.
House was built 1963. Would be grateful for views on:
- What are the chances that the roof is reinforced with rebar?
- Is it possible to confirm that with a detection tool, along with centres etc
- Is cutting a hole even a starting proposition?
- Assuming a structural engineer and BCO approve, how difficult would it be to cut an access hole if it is reinforced?
- Whether or not it is reinforced, would you need kango/percussive tools to do the job?
