Belt and braces shed roof installation advice please!

[8-P]

Hi All

My PH favourite Tiger Shed has arrived. Its an 8X5 pent so nothing massive but I want to get it installed right, dont want to be fixing it in 3 years time.

Base is all sorted, probably overkill. Im treating the walls with Ronseal 5 year woodstain which Ive used before, its quite thick and Im happy itll be ok.

So questions are around the roof.

Can I stain the roof with the same Ronseal? This would seem to add another layer of protection to me?

It came with some of this felt - http://www.rose-roofing.co.uk/rose-roofing-product...

Seems to be a reasonable quality, but it does mention using underlay, or should I fit something totally different?

Many thanks

Thanks all. Think Im going to buy underlay and adhesive, then put the felt provided which seems to be reasonable quality on closer inspection. Should do the job, the shed will be in a sheltered spot which should help a little.

Nail,the underlay at 300 sq centres, bond the mineral. You will end up covered in adhesive.

Nail the selvedge of the mineral and on the headlap. Put a seperate flashing to cover.

Thanks Roofer, mostly makes sense
