    Mechanical fixing mortared ridges

    The standard (BS 5534 2014) was clarified via a 2018 amendment, which specifically states that it does apply to repairs and maintenance. So yes, technically even a single ridge tile replacement would require mechanical fixing. The only exemption is for heritage buildings. It's a bit of a...

    Need some advice on my roof

    Yes, a level 2 report would be expected to include comment of the apparent suitability of tiles for a low pitch. There are ways to use tiles below their guide pitch, but as this type of survey is visual only, there would be no way of knowing how the underlay has been designed or fitted...

    A lot of moisture in insulated outbuilding

    Likely still drying out if it has just been built. Make sure the dehumidifier is suitable for the area involved, keep it on and close all vents. Wait until the amount of moisture being collected reduces

    Cavity Wall Insulation Question

    With the retro-fit market, and particularly grant funded schemes, the installers were under pressure to complete several properties per day and it was common for installs to be done very quickly and haphazardly, with some areas missed completely. Either have a thermagrahic survey done, or get...

    Suggestions on sealing old flat roof pipe against brick wall

    Yes, I'll trade you for next week's lottery numbers. Flashband over any pipe joints, pipe to roof junction and any potential movement joints as reinforcement, then acrylpol over.

    Extension Insulation Detail

    Didn't your plan drawer detail the high risk areas? You need a slot cut for the cavity bridges, and insulation around the beam. Don't forget the cavity tray above.

    Cavity Wall Insulation Question

    Some builders used a post-build blown in system on their developments, others may have used insulating blocks and relied on a whole house u-value calculation which did not require additional wall insulation. All retro fit installs should be recorded via a building regs notification.

    Suggestions on sealing old flat roof pipe against brick wall

    You can't make the pipe penetration leak proof when the roof is in such a state Acrylpol (and flashband). Buy a big tin and do the whole roof.

    Retrospective plannimg for loft bedrooms

    The "proper" staircase would be more pertinent than the state of the loft rooms, as that implies that the rooms existed as rooms with an access - irrespective of any subsequent change in regulations or your refurbishment - which is not a conversion in context of planning law. Key dates would be...

    How to identify if concrete blocks are 5N or 7N ?

    The fact that the blocks are hollow may be more pertinent than the compressive strength and even if 7N, may still require increased padstone, larger spreader plate or localised rebuilding with either solid blocks or filled voids. Make sure your engineer has factored hollow blocks in.

    Am i missing roof flashing?

    Looks an OK job. Perhaps the tiles should be a little further off the wall to prevent the secrete gutter from blocking, but not the end of the world. However, you need to look up between the flashing and the bottom of the render to check if the flashing goes up behind the render or if there...

    Leak in bay window

    Latent defect and contract claims are under common law, not a warranty claim. Under contract law, if valid, you would have 12 years to make a claim against the NHBC for their negligent inspections for the warranty - these are not and distinct from the building control inspections. Under...
