If you need to make a repair to your mortared tile roof, then you will need to mix the cement mortar correctly. The correct mortar consistency is vital to ensure the cement cures properly into concrete and secures the roofing tiles.
Once mixed, then working correctly with the mortar will ensure a professional look for your roof repair and will ensure the roof stays leak-proof for many years to come. If you have never repaired a mortared tile roof, then these tips will assist you with the project.
Tip: Wear Eye and Lung Protection
Since you will be working with sand and lime, you need to wear a pair of safety goggles and a particulate mask while mixing the cement.
Tip: Rent a Cement Mixer for a Larger Repair
When you mortar a tile roof, you will be using a lot of cement. If you are repairing a large section of your roof, then do yourself a favor and rent a cement mixer to make the project a lot easier. With a cement mixer, you can shovel in scoops of cement mix, sand, and lime and will be able to mix all of the mortar at the same time.
Tip: Use the Correct Mortar Amounts Under and Between the Tiles
When you place the mortar on the plywood sheeting, you need to completely fill the area between each set of tiles as well as having a thin layer below each tile. Each tile needs to sit on some mortar to keep water from soaking the plywood below it, and each tile needs mortar surrounding it as well to prevent breakage.
Tip: Finish Off the Edge of the Mortar for a Professional Finish
Once you are finished laying down the tiles, then go back and finish off the edge so anyone looking up at the roof will see a professional-looking edge. To do so, trowel away any excess mortar and smooth down all of the mortar. This step also prevents small birds from nesting under the roof's tiles.
Tip: Don't Forget to Punch Weep Holes Under Each Tile to Drip Away Moisture
Finally, once the cement mortar has started to harden and cure, then you need to punch out weep holes under each tile to drip away any accumulated moisture from stormwater. To do so, use a small screwdriver and poke a hole about an inch deep into the drying mortar just above the plywood sheeting.
