hi byron
just noticed that you ask how to fix shingles
what you do is start at the bottom , fix the first row , nailing them direct to your substrate , in your case osb and one layer of felt
the second row goes on over lapping the first and covering the nails at the same time
{IIRC} these shingles are not really suited to roofs below a certain pitch
this puts you out of it as far as shingles are concerned
im no expert roofer . but have had some dealings with this kind of roof
in the past . so feel free to critisise and correct any points that i may have missed . :roll:
a "built up felt roof" done properly will cost a small fortune
you will need to hire a bitumen boiler and buy the cakes of bitumen
the woodwork has to be at least 3/4" thick and tight jointed
on the front , back , and highest edge a strip of wood , say 2x2 cut diagonally has to form a perimeter around the three edges .
with me so far . good then ill continue
cut your strips of felt to go on so that the roof is covered high point to low point
cut another lot or felt so that it it is covered front to back
both these layers are now ready to be bitumened into place
note : dont go any further than the perimeter fillet youve installed on the three edges
now you are ready to start sticking down
when the first two layers of felt are stuck down
you are ready for the capsheet . or "traditional felt"
stick the capsheet to the first two layers of felt in the same manner with the bitumen,
at this point the roof is pretty watertight , but you will need to finish off all
around the edges .
this is difficult to explain ,
long pause
right . here we go .
the underside {what you see from the ground} has to be folded under . nail the face of the capsheet direct to the barge board
so , lets say your barge board and perimeter fillet are 8" deep
mark a line 4" up . nail all your felt to the barge board making sure the falt is dangling earthwards . then fold the felt back up onto the roof
from the top now, stick it to the barge board , fillet strip and a generous overlap onto the capsheet .
do that all the way round folding the felt up and sticking it to itself
you will then have a roof that should last in excess of twenty years
ohh, you can then add a thin layer of stone to help absorb the heat from the sun .
like i said , im no expert , but im blessed with a wealth of first hand experience knowledge . { at work we use subbies, cos they have all the gear} :x :x
alternativley you could use roofing sheets :lol: :lol:
here ends the tutorial on "built up felt roofing"
hope ive not done your head in #-o
