One great advantage of standing seam metal roofs is contained in the name itself: seams, the weak point in any roof and a potential entry point for moisture, are raised above the level of the roofing panel. You can’t say this for composition shingles.Because the metal panels run unhindered from the top to the bottom of the roof, not only are there no horizontal seams but in total the roof has a far fewer number of seams.
Modern metal roofing systems come in nearly an infinite amount of colors, many finishes and are extremely flexible in terms of shapes and curves. The material choices of Aluminium, Steel, Copper and Zinc also offer their own individual design and finish options. A standing seam metal roof can provide excellent acoustic ability when coupled with complimentary materials that form a structural barrier to minimize drumming and sound attenuation. An engineered combination of perforated metal roof deck profiles and acoustic insulation, can drastically reduce sound reverberation.
