How Do You Install Plastic Roof Tiles?
A plastic roof is a waterproofing system composed of sheets of PVC plastic that can be interlaid to create a protective layer over buildings and other structures, such as in conference centers, museums, or laboratories.
The installation process for this kind of roofing is given below Fixing Battens., Fixing Eaves,
Calculating Gauge, First Course, Continue Laying, Ridge Cap Finishing, Valleys, and step flashing.
- Fixing Battens. Begin by securing the battens to the desired gauge over the overlay. This means locating the battens with the overlay and checking that the overlap is precisely measured. Preferably, this should be done by someone with a good eye for detail.
- Fixing Eaves. This is not a perfect solution, but it can at least prevent water from getting in the eaves. Place a 3/4-inch slate on the inside between the two pieces of wood. This should keep moisture from getting in and running down onto the roof. The slate will keep it from getting into the house.
- Calculating Gauge: Your desired building gauge is the main factor determining how much overlap you should use. This is expressed in inches and is worked out by multiplying the width of your building by its length (in feet), then dividing that figure by 12.
- First Course. Lay the first course of panels using a batten as a guide on top of the overlap.
- Continue Laying. With that first course in place, you can slide the rest down without them shifting about or bunching up, and then you secure them by stretching wet hessian sacking over each one and fixing it onto the battens with staples.
- Ridge Cap Finishing: Once all of your tiles are in place, you need to apply a ridge cap to finish off your roof from above and create a suitable seal between your plastic sheeting and the metal framework that holds it in place.
- Valleys. Install valleys by sliding the ridge cap into place and then carefully cutting a V-shaped groove into each side of the valley to accept it.
This can be done with a saber saw or using a framing square as a jig. Once installed, you will need to seal the valleys with roofing cement to ensure that water cannot flow down inside them to collect and eventually rot your plastic roofing system from beneath.
- Step Flashing: Use pieces of metal flashing to cover the spaces between your steps and your plastic roof. A 15mm (0.6 in) piece should be enough to do the trick. This should prevent water from seeping down through any gaps.
- Ridge Flashing: If you have a ridge, install additional ridge flashings over the top of it for protection against the elements and heat loss through its underside. When taking measurements for your gazebo, buy building materials online.
- To finish off, apply a generous bead of roofing cement to all joints before driving a nail along any seam longer than 2 ft (0.6 m).
