The drop ceiling tiles protect sloping roofs of the effects of rain, snow and hail, as well as give the house an attractive cover. Maintaining a solid layer of shingles is an excellent way to prevent water damage and leaks. If you install the tiles properly, you have no problems over the next 20 or 40 years. The installation of tiles can be a difficult job, but the rewards of having a waterproof and attractive roof can be worthwhile.
Measure the drop ceiling tiles properly. Depending on how you organize the rows go, you can choose to cut 5 different sizes of tiles using the basic choice of 3 tabs. Basically you can cut half a tab (wide) to start the first row, accommodating the “notches” to modify the area needed to fill each row. Usually these cuts are useful:
Installing a starter strip at the lower end of the roof along the edge. Nail the drop ceiling tiles at a distance of about 18 mm above the notches, near where the tab reaches the top of tile. Also put a nail at a distance of 50 mm from each end of the shingle. Line them up with nails that are on the notches. In total you should use 4 nails per shingle 3 tabs.
