Laying the top bonded layer of top sheet felt.
How do you felt a flat shed roof.
It s best to start nailing in the center and work out from there.
Installing any gutter drips.
You can do this by calculating the length and width of each side of your roof.
You can either measure the roof from the ground or by standing on a ladder and actually going up on the roof.
Laying the second bonded layer of underlay felt.
Follow the 10 steps below in order to felt a flat roof.
Laying the first nailed layer of underlay felt.
Once measured and cut line the first piece of felt up so that it over hangs the edge of the roof on three sides by enough to cover the side pieces of the roof.
Line up the loose edge of the roll with one of the bottom corners of your roof and fasten it using 10 12 staples grouped closely together near the center of the strip s edge.
Simply multiply length x width and you will find the area of one side.
Multiplying these two together will give you the square footage of the roof.
Gradually unroll the paper across the rooftop stopping to add more staples every 1 2 feet 0 30 0 61 m.
For hip type shed roofs which include slopes on all 4 sides begin at the square hip at the top of the roof.
Attach strips of felt roofing paper for baseline protection.
There needs to be an overlap in the felt to help increase the water tight quality.
Begin at the bottom right or bottom left of the roof.
You can hammer in the nails along the bottom edge of the roof at wider intervals around one every 30cm.
You will then need to measure the length and width of the roof.
You wan walk over the roof to remove any air bubbles that may form.
The first step in felting a shed roof either angled or flat is calculating the exact dimensions of your roof.
Once you ve secured the side panels in place add the top section to the ridge and fix it using high performance felt adhesive applied with a paint brush then nail it at the lower edge at 5cm intervals.
As you roll it out make sure that it remains flat.
Apply the cut felt to either side of the roof pulling it tight so that it lies flat before nailing it at around 10cm intervals along the length of the roof just below the apex.
Paint a thin layer of adhesive over the first felt layer.
The sequence of laying a felt roof is.
When you are felting a sloped roof you start at the bottom and work your way up so that rain pours over the top of the laps and not under them.
