Firestone RubberCover is known throughout the industry as an exceptionally high performing material, making it great for roofing projects of all shapes and sizes. However, the material is only as good as the people fitting it, which is why we regularly offer training courses from our premises in High Wycombe (Buckinghamshire) and Winsford (Cheshire).
You might just need a few pointers though, so with the help of Firestone, we’ve collated an informative guide of best practices for fitting these materials. It’s a lot easier to install than other materials on the market, but you still need to do it correctly. Let’s get started.
Adhering the Material
You must always adhere Firestone RubberCover to the substrate. This is completed by applying bonding adhesive to the membrane and the substrate. Various substrates are compatible with RubberCover, including wood, bitumen and concrete. (Though it is compatible with much more too.) It’s an incredibly versatile material, as it can be used on both new and existing roofs, providing the existing structure is suitable.
One Seamless Sheet
RubberCover membranes are available in large, seamless sheets, so most small residential roofs can be covered with one sheet. However, you may need to splice the seams together. This can be done with QuickSeam Cover Strip and QuickPrime Plus, which are also Firestone products. One thing to note – do not leave a space between adjacent EPDM membranes, though a slight overlap is allowed.
Don’t Cut Those Corners
Applying the material to corners requires bonding adhesive and roof trim, and other materials may be required if you’re applying it outside the corner. (E.g. if you have a skylight.) It does depend on these circumstances:
- Inside: You’d need to adhere the membrane with bonding adhesive and roll the excess membrane towards the corner. You’ll then fold the membrane flat onto the roof edge and finish the edge with roof trim. Once this is done, simply trim off the excess membrane.
- Outside: This is a bit trickier, but Firestone has a handy guide here with all the details. We also provide training courses that cover this too.
Drainpipes and RubberCover
As an outlet for water, it’s vital that the area around drainpipes is sealed correctly. You’ll need to first place the rainwater drainpipe at the correct angle before screwing it tightly to the substrate. Then apply QuickPrime Plus to the top of the drainpipe and then at least 10 cm around it. You’ll then need to wait for it to dry before continuing.
Once it is dry, adhere the QuickSeam SA Flashing over the drainpipe and onto the membrane. The strip should overlap the edges of the drainpipe by at least 5cm in all directions. Then, just roll it with a hand roller and cut an opening into the flashing strip so that the rainwater can enter the pipe. This should allow for water to enter the drainpipe without damaging the roof, due to the durability and water-resistant qualities that EPDM has.
A Helping Hand – Avenir Roofing
As a roofing material, Firestone EPDM RubberCover is unparalleled. It’s immune to ozone, UV radiation, and cold cracking, and there are environmental benefits to using the material when compared to other options on the market. (Its 50-year service life and recyclability are just some benefits.)
