A block and tackle is system of pulleys for making lifting and pulling easier.
How to tie three roof systems together.
To keep the porch roof framing as simple as possible we installed a structural ridge supported by posts at each end with the common rafters landing on top of the ridge.
A pulley system is made up of two or more pulleys connected together with rope in such a way as to provide mechanical advantage.
Building an addition on a house requires connecting two roofs whether the new space is a wing of living areas or a carport.
After the addition roof is framed and sheathed snap a line on the existing roof shingles 2 in.
This new roof with a higher pitch can be accomplished with premade roof trusses and typical asphalt shingles.
The roofing cement will resist possible leaks overnight.
The easiest way to tie in the new shingles with the old is with a cut valley see four ways to shingle a valley.
We re going to do a pitch transition or change.
We need to do something where that change happens so the panels can go down and water can come off hit the lower slope and come off the roof.
This is important to minimize the chance of any water being able to penetrate the gap.
The new roof will need to be cut to the right angle so that it fits snugly against the roof.
Replacing a roof can be expensive but if a roof contains only a small slope it s possible to raise the roof pitch of a house by building a roof over the old one.
Up from the valley center and cut through the shingles and underlayment.

The new roof now needs to be connected by nailing through the board into the joists.
This is an important job and needs to be done.
There are many roof.
Mechanical advantage means the ability to turn long low power pulling motions into short high power pulling motions.
Step 3 connecting the new roof.
Using a pitch measuring tool that i d made we also determined that the exact pitch of the shed roof was 3 1 2 in 12.
