Work upwards from the gutter and make sure that all joins are horizontal and there is a good amounts (4 inches)of overlap, use some bitumen 'paint' to stick the pieces together where they overlap.
It's quite an easy job really.
Typical varnish, felt and some sealer and decent glue or tacks.
Not the correct way though.
use under felt first in one direction then cover with the roofing felt. try and lay it on a sunny day, cut your felt to length then leave in the sun for a bit, helps soften it up for laying
Felt is sh*te IMO.
Use this stuff http://www.wickes.co.uk/Bitumen-Corrugated-Sheet/invt/240039
will last years, I put it on my shed when the felt started leaking.
Nice one pies I'm gonna try that in summer!
Measure the length of the roof and then add on about 15 inches,cut your felt to this size,roll out on lawn to cut, and always try to cut with either a hooked stanley knife blade,and always away from you.
Roll up this piece and place on roof,unroll from the end of the shed and slightly over lap,at the end,pull gently down to the gutter line, and then using clout nails, ensure they are short enough not to penetrate the roof,then nail every 4 inches along the gutter line,puulling felt gently, until you reach the other end,
Next pull the felt up and do the sme ensure that its tight,along the top, you can us eless clout nails here as it will be covered by the top caping layer,latter.
Now proceed to do the same the other side,then fit the top capping piece, and do the same the capping piece should lie equaly on either slope,now clout nail this all along the joins.
a few 2 x 1 treated batons down the slope will stop the felt lifting and ripping.
Best to get a freind to help you and dont try this on a windy day as youll rip the felt.
Sent you an email with some more info.
Above all, don't buy 'shed felt' it's shite. Pay more and get the heavier duty stuff.
Although I'm going with the corrugated stuff this spring.
