Tips for Installing Plastic Fascia Tips for Installing Plastic Fascia
Plastic fascia is a good choice to complete your roofing installation. It is made from vinyl which has a wide applicability in roof projects. Plastic is a popular material for fascia because of its low maintenance requirements. Although wood is widely used for fascia, it is highly susceptible to damage by moisture. This necessitates regular maintenance to prevent mold growth and rot. Plastic however has a high resistance to moisture. This makes it an excellent choice for fascia if you want to weatherproof your home well. Ease of installation also draws homeowners to choose vinyl fascia. Below are a few tips that will help you install yours properly.
Take the measurements of the various places along the roof where you intend to install the fascia. Try and obtain individual pieces of vinyl that will fit into each side of the roof for a more effective seal. When you install 2 or more pieces of vinyl fascia on one side, the seams lower the possibility of a watertight seal.
It is best to cut your fascia pieces slightly longer than the measurements you took. If need be, you can easily trim them back to the required size. This will ensure that a single board is used for each side rather than 2 or more boards. It gives you a more watertight seal. You’ll need to make angled cuts for ends that join together at corners. Avoid use of normal blades to make these cuts as it may damage the vinyl fascia. Obtain a special tool from the hardware store that will allow you to cut through vinyl accurately and safely.
Undersill Trim and “F” Trim Installation
You need to install some undersill trim and “F” trim to hold your plastic fascia in place. Attach some undersill trim on the wood fascia board in a straight manner along the top edge. If you fail to achieve a straight arrangement your vinyl fascia will appear wavy. Secure some “F” trim at the bottom edge of the wood fascia board. You’ll need to trim off some plastic from your fascia panels before you fit them into place. Measure the distance from the top of the undersill trim to the bottom of the “F” trim. Deduct 1/8 of an inch from your measurement. This gives you the width of the fascia panel you need to cut.
Both sides of plastic fascia boards bear a similar appearance. However, if you look keenly, you’ll realize that one side has more imperfections than the other side. It helps if you mark the imperfect side. When you install the fascia, be sure to place such that the imperfect side faces inwards to the house.
Slide the trimmed edge of the fascia panel into the undersill trim. Draw a line where the panel intersects with the trim. Use a snap-lock punch to make raised lugs slightly above this line at intervals of 6 inches. The lugs should face outwards. Lock the bottom of the fascia panel into the “F” trim below. Push the top of the panel into the undersill trim. The raised lugs will lock the fascia into place.
