A standing seam metal roof is becoming one of the great options for house roofing these days. The metals that are placed side by side with each other and are fastened creating a seam which not only creates a better look for one’s roofing but also gives homeowners the satisfaction of getting to use their roofs for quite a long time. Homeowners whose houses frequently experience an amount of snow pours will never have to worry since standing seam metal roofing easily drops off ice and snow thus it keeps the roof light and ventilated. Having seen a roof with standing seam metal, you may think that this is a job well left to accomplished designers only. What is great is that you can actually create a standing seam metal roof on your very own house.

Step 1 - Determine the Size of the Roofing

To help you determine the right size of metal panels for your standing seam metal roofing, you have to measure the size of your existing roof. Get both the length and the width as this will determine the cuts to be made on the metal panels.

Step 2 - Prepare the Roof for Installation of New Metal Panels

It would be too bulky to simply just overlay the new seam metal roofing over the old roofing material. It will also add more weight to the roof which may add additional damage to the trusses. Thus, it is important to remove existing materials first before adding a new one. Use a pry bar to remove existing roofing materials. Also remove the old underlying material such as plywood. Make sure to replace it especially if it is already rotting. Put in the new waterproof underlay material and nail the bottom side to the roof. Apply sealant to spots where two underlay materials overlap to prevent water leakage.

Step 3 - Install the Metal Panels

Once the roof is ready for installation, you may now cut the seam metal panels according to the measurements of your roof which you obtained earlier. You can also purchase pre-cut metal panels in the size needed. Get the ridge cap and follow the manufacturer’s directions on how to fasten it in place. Put it on the highest section of the roof as it serves as the base for installation of the vertical panels. From the ridge, place each metal panel side by side. Secure the panels into the underlying material of the roof using metal fasteners or clips. To create the “seam” like appearance of your roof, raise the edges of the metal panels. Using a crimping tool, create a crease by folding the edges together. Make sure that the edges are secure and well folded to prevent water from leaking into your home.
