Metal roofs, though highly resistant and aesthetically pleasing, do require a certain precision when it comes to installation. Whether you are a professional or amateur installer, following best practices and avoiding common errors are essential aspects for achieving impeccable results. Here are a few tips from Éric Simoneau, installer from Ferblanterie SL (St-Charles-sur-le-Richelieu) for a successful installation.
1. Evaluate the structure
Before starting, it is essential to evaluate the roof or wall structure to ensure that it is perfectly straight. To do so, create a cord grid with vertical and horizonal lines. Be sure not to rely on a visual approach (i.e. don’t eyeball it), because even a slight difference can be noticeable long-term and compromise the solidity of the installation.
Also, if the plywood was installed with H-clips, it is preferable to avoid adding metal cladding directly on top as they may be visible once the metal is in place. It is a good idea to fix this before proceeding.
2. Ensure the membrane is not bent or wrinkled
If the membrane has any bends or wrinkles, it is important not to ignore them. Be sure to smooth them out before installing the metal cladding. If not corrected, this issue can make the metal ripple and compromise its water resistance and aesthetic appearance. Be sure the surface is as smooth and planed as possible before starting work.
3. Install edging
Edging is crucial for final project results. Take the time to install it properly, while ensuring it is perfectly straight. A home or building with perfectly installed edging will give beautiful results. Once edging is installed, create a cord grid along the ridgeline and valleys to guarantee everything is aligned. This will give a first impression of quality.
4. Predrill metal cladding beforehand
It is important to predrill metal sheets before securing the screws. This will ensure correct alignment and avoid scratching the roof with sharp screws.
5. Cut valleys correctly
Valleys are also key to the final aspect of your roof or metallic covering project. It is important to find the right cut angle to guarantee a clean finish. Be sure to respect the cut angle throughout the process so lines are uniform on both sides of the valley. Do your research on recommended tools for cutting.
Specific advice for Ancestral cladding profile
1. Avoid structures with widely spaced joists
It is important to understand that wide-spaced structures are not an ideal base for installing metal cladding. This can cause warping and other problems in the long term.
2. Leave space for dilation with Ancestral cladding profiles
When installing Ancestral cladding, be sure not to tighten too much. It is important to leave space for material expansion, caused especially by temperature variations. Screws must be installed in openings created for this purpose, but not too tightly. A waterproofing seam in the ridge cap can also allow this expansion while ensuring a good seal.
3. Stapling the Ancestral profile: technique and patience
When you staple cladding sheets to each other, it is crucial to put pressure just under the place you are stapling. This will allow the cladding to be secured gradually, guaranteeing a uniform installation. It is recommended to use a rubber mallet to avoid damaging the cladding. This method ensures stapling that is neat and sturdy.
Closing Remarks
Last but not least, our final piece of advice is to take your time throughout each step of the installation. There’s no need to hurry. Metal cladding is a flat, grooved material and neglecting little details during installation or stapling may show at the end. It is essential to be meticulous every step of the way to avoid errors that will affect the appearance and durability of the cladding.
Successful metal cladding installation requires preparation, precision and patience. Take your time, ensure that everything is well installed and remember to use high-quality materials to obtain a flawless result. By applying best practices, you can be sure that your project that will live up to your expectations. Have fun!
