Thanks Sharad! Glad we could help :)

That is great to hear David and hope our video helped you. Have a good day :)

Hello Jannick, we had an agency create it for us, so unfortunately we dont know, sorry.

The thicker material is more rigid, and can therefore span a greater distance.

Hi Evan, maintenance can vary between material finish and location, i.e if your near the coast you will need more maintenance than in-land locations. Our leathergrain coating has great durability and requires less frequent maintenance.

Hi Adrian, many thanks for your comment and we can certainly help you with your question. If you would like to call us on 01342 315300 and we will be more than happy to help you. Have a good day.

Yes. Yes you do.

If using the correct fixings with EPDM washers, tighteneted correctly, this should not be an issue. I would check the type of screw used.

I have to agree and have done many small roofs with these sheets and always fix through the ridges. My thinking like yours: If any fixing might leak then at least it's at the highest point whereas if fixed through the 'valley' Sod's law says it will be at the lower end of the sheet at the point where. most of the water will be, i.e. in the middle of a river. Likewise I've never seen the sense of fixing roofing felt with nails. If you search on youtube you'll find more than one channel on these sheets recommending fixing on the high points.

Hi Mark, if you visit our website you can see prices which are based on quantity. www.southernsheeting.co.uk/box-profile/c-263.html. Please do not hesitate to contact the team should you require any further help.

You should fix the main fixings to the low part of the profile - the video is correct. This method avoids denting the crown and ensures a firmer fixing point as the screw engaes straight into the joist.

Nick - This is worng advice. Special saddle washers should be used if fixing through the crown of the sheet to avoid denting. Please refer to a number of manufacturers installation guides on box profile. You are however correct if fitting corrugated profiled steel sheets.

@@duncankingston50 OK, I'll qualify my advice. In practical terms, there is never a case for putting the screws in the valleys, even for box profile roofing. Don't allow anyone to do this to your roof unless you can be sure they will be around in twenty years time to fix the damage caused when the washers fail. And some of the the washers will fail because roofers always over or under tighten some roofing screws. My objection is that the video shows this as 'the' way to fix roofing sheets, and does not warn users of the potential pitfalls. It's simply a risk roofers don't have to take.

​@@nickreid5297​ You haven't warned users of anything either. Too obvious to spell out? What sort of comment is that? If you have something to say, say it, or keep it to yourself

@@007alztruli OK, I'll spell it out for you. If you put screws in the valleys, water will eventually leak through, rotting out the roof structure. This will happen if the roofer over or under tightens the screw, or years down the track when the washers deteriorate.

​@@nickreid5297i think the tricky bit is that with this box type cladding you have a flat top not rounded like with corrugated sheets that means you can not tighten the screws enough as the flat will pull down, an arch has more structure. Therefore you will bend it and the washer wont sit right and wont be pinched right. My 2 cents anyway. I am installing my roof in the next few days.
