Which felt for new shed?

[vw754]

I've purchased a new shed and want a good felt for the roof , a local company has said they have 250 gram mineral felt for £71 (Chester felt)
I've found one on Amazon for £50 which is 24 grams , am I right in saying there's not much difference between the two ?

Also the more the weight it is , does it mean it will be more thicker?

I want a thicker one that's going last a few years.

Just fitted skyguard rubber sheet roofing to both my sheds roofs.
I`ll never go back to felt after using this.

I replaced our shed roof with a metal one after i got fed up fixing holes in the felt caused by wood falling off trees.

Surely there’s got to be a world of difference between 250 grams and 24 grams?

When I refelted my shed roof, I first covered it with a sheet of 10mm ply, then I used a mineral felt (don't know what weight it was but it was allegedly guaranteed for 10 years so quite thick) and I stuck that on with felt adhesive.

When my large felted workshop decided 10yrs ago the covering was past its best, I ripped the lot off and reboarded with OSB before coating with resin bonded glass fibre. Money well spent IMO, because it's as good now as the day the work was finished

If you want the roof to outlive the shed below by about 10 years and never intend moving the shed, use rubber.

If you just want the roof/felt and the shed to live in harmony and eventually die a peaceful death together, tack some mineral felt on it.

Yeah I built a half decent shed and I expect it to last a number of years. I had my flat roofer cover mine.

You didn't give a size for your shed but going off that you proposed buying 10sqm of felt, you can get eg eBay item number 255117176752, a 3m square offcut of rubber is 66 quid

Given a choice between the two being roughly the same price, I'd get rubber (noseall's reasonable point about shed longevity notwithstanding)

My garage came with a corrugate cement roof, I originally built my summerhouse and hut, with felt rooves. When I added the extension to the garage, a workshop I used corrugated box-section, steel, galvanised and pre-painted. The felt roofed summerhouse and hut, have needed to be replaced and repaired, due to wind damage, several times.

I was so pleased with the workshop roof, I went onto replace the entire garage roof with the steel. Then couple of years ago, I replaced the summerhouse felt roof with the steel. Only the hut, still has a felt roof, but I will not be repairing it with felt again, when it needs it, it will get a steel roof.

The steel is much more robust, never needs any repair, doesn't suffer from the UV of the sun, and in the 20 years since I built the workshop, there is no sign of any of the panels rusting.

Have you insulated the underside of the sheets Harry? The biggest nuisance we had over the years with my dad's metal roofed garage was condensation on the underside - it was just joists with the sheets screwed to them directly, and the drip-off from condensation used to ruin a lot of stuff in the garage

Yep, I have now - I had a problem with condensation. I used flame retardant polystyrene sheet.

I considered those, long ago, I discounted them, as being very lightweight, and quite fragile.

 

[aveatry]

They are actually quite strong and i often stand on them to cut the top of a hedge. Best with a board across though.

They are as low end a roofing product, as you can lay your hands on.
Horrendous.
