2. Prepare the foundation. The foundation for your roof concrete block wall should be a level, solid surface. If you are building on a concrete slab, you may need to roughen the surface of the slab to create a better bond between the concrete blocks and the foundation.
3. Lay the first course of blocks. Start by laying the first course of concrete blocks along the foundation. Make sure that the blocks are level and that the joints between the blocks are tight.
4. Continue laying the blocks. Continue laying courses of concrete blocks, stacking each course on top of the previous course. Stagger the joints between the blocks so that they do not line up vertically.
5. Reinforce the wall. Every few courses, you should reinforce the wall by adding rebar. Rebar is a type of steel rod that helps to strengthen the concrete and prevent it from cracking.
6. Install the roof joists. Once the concrete block wall is finished, you can install the roof joists. The joists should be attached to the concrete blocks with joist hangers.
7. Finish the wall. Once the roof joists are installed, you can finish the wall by applying a layer of stucco or paint.
Here are some additional tips for connecting roof concrete block walls:
* Use a mortar mix that is specifically designed for concrete blocks.
* Make sure that the joints between the blocks are completely filled with mortar.
* Allow the mortar to cure completely before moving on to the next step.
* Take your time and do the job right. A properly constructed concrete block wall will last for many years.
