Slating is a process that has happened over hundreds of
years. It is a system that guarantees secure roofing with only problems
occurring in extreme circumstances. Slating is relatively cheap and will not
take a long time to create however, slate roofs are becoming more and more
frequent thanks to the protection they offer.
Before we look into materials and options, the first thing
required is for you to find out the pitch of your roof. To do this you can
download an app onto your Smartphone which will accurately workout the angle of
Once you have your angle, this will establish what size
slates you must use and how big the overlap must be to maintain the waterproof
feature. Here is a link
to an online calculator that will work out everything you need to know,
alternatively you can contact any slate manufacturer and they will also be
happy to help.
Once you have ordered your slates then make sure you check
the weather report as you cannot work in the rain. A dry weekend is perfect.
Now for the slating.
Give you roof rafters a once over and remove and
old nails or splinters and sand any hard parts down.
Grab yourself either under-slater’s felt or roofing
membrane and lay it out horizontal
across the rafters.
Nail one side of the felting so that it is not
tight but will remain in position without ripping. We advise 1 inch galvanised
Pull the opposite side of the membrane so that
it is not tight and has a little sag between each rafter. Nail
down once more and then nail the rest of the rafters so that it is fixed.
slates are attached to what are called battens. To work out how many battens
your roof requires is easy. Using a single slate, add an overhang of the slate and then where the middle of the slate lies,
fix your first batten. Then using a second slate work out the distance
between the two and then you have your distance. Now we divide the distance into the overall length of the roof the find
out how many are required.
Fix the battens to the shed roof, accurately measuring the distance each
time so that you do not have problems occurring when laying the slates. An easy
little hack is to cut three spare pieces
of timber perfectly so you can slide them on top of a batten and then it
rests whilst you nail it down. Continue until the roof is full.
Now it’s time for your starter course, the first
layer of slates. This layer will be the edge of the roof layer, just like we
added the single one before. To maintain the vigour of the roof this layer is
best done cut in half. Just above the two holes on the slate chop it off and
position on the roof until the first line is complete.
Now you can continue each line as normal, using
40mm nails you can fix down the slates but remember not to nail down too hard
as it may penetrate too far into the wood and out through the membrane. Instead
of walking over your slates, start from one side and work inwards on yourself
diagonally. This is ideal as it gives you more of a visual gauge to the slates.
Once you reach the top of your roof, again using
half slates, attach them to the top of the roof and this will keep the roof
Finally, using lead toppers you can secure and
finish the roof. The lead toppers fit on top of the roof corner and stops any
chance of rain coming through as well as visually adding a lovely finish to the
