For some people, the pitter-patter of rain on their metal roofs is a comforting and welcome sound. For camera or sound operators who record video or audio files at home, loud raindrops can be a hindrance and a frustrating distraction. If you love the look of a metal roof and you still want one installed on your home despite the noise, here’s what you should know about how to lower any metal roof-related noises.
Understand Metal Roofing Types
The stiffer a roof’s metal material is, the less likely the metal roof is to move or respond to pressure. Even slight movements of flimsy metal roofing panels can create loud, annoying noises.
Several types of metal roof coverings are available. Metal roofing panels may be constructed of tin, aluminum, steel, copper, or an alloy of several metals. Steel tends to be the stiffest material for metal roofing panels and, therefore, may be the quietest roofing choice.
The stiffness of a specific metal roofing panel also depends on the profile of the roof covering. Standing-seam and flat roofing panels sit directly on roof decking, so they vibrate less when exposed to wind and rain pressure. The extra structural support makes these types of metal roofs quieter options.
Corrugated or thin metal roofing panels may vibrate too much and create loud sounds when it rains or the wind blows. Some metals may groan or creak when exposed to changing temperatures. Ask your roofing contractor to use the stiffest metal roofing panels to cut down on metal roof-related noises in your recording spaces.
Hire Professional Installers
Even a stiff roof can cause noise issues when the roofing panels, end pieces, and ridges are not properly fastened to your roof’s underlying structure. Screws and fasteners can be fastened too tightly or too loosely when DIY types or inexperienced roofers apply metal roofing panels. The wrong screws can corrode metal or allow water to penetrate the roof decking. Then you get a loud and leaky roof.
Expect lots of roof noise if metal roofing panels are not fastened to some type of decking or to previous roofing materials. A professional roofing contractor won’t allow metal panels to be applied straight to trusses. They know you’ll have an extremely noisy (and likely out-of-code) metal roof if metal sheets are applied without proper decking, underlayment, and properly spaced fasteners.
More fasteners can be added to an existing metal roof to correct fastener issues. However, a professional roofing crew will install metal panels the correct way from the start. They’ll use two rows of screws on ridge covers and special roofing fasteners with washers where necessary.
Order Special Underlayment and Wind Protection
Your roofing professional can source a variety of roofing underlayment materials to cushion your metal panels and protect your roof decking. Water- and wind-resistant roofing underlayments offer thermal protection and noise-dampening features while they protect your roof from storms.
Some underlayment materials offer more noise reduction than others. Research materials and ask for advice from professionals before choosing the underlayment for your metal roof. If you record videos or audio in only one area of your home, consider investing in higher quality roofing underlayment for that specific section of roof.
Insulate Attics, Trusses, and Ceilings
Insulation is a noise dampener, so schedule insulation of any exposed areas between roof trusses when you have your new metal roof installed. Add insulation to the attic floor, between the rafters, and in gaps around attic vents and windows.
For extra noise dampening in a room directly below the attic, hang a drop-tile ceiling or apply acoustic foam to the ceiling after insulating the actual ceiling surface. Foam acoustic panels lower roof noises and help keep loud sounds inside your recording space.
Use Noise-Dampening Paints and Screens
Noise-dampening paints are available to help deaden sound inside and outside of spaces. Noise-dampening paints are thickened with ceramic microspheres and other noise-reducing fillers.
While noise-dampening paints can be used on many surfaces, you probably won’t get away with painting your roof with the material. First, you could void the warranty of your roofing panels, and second, the approach is cost-prohibitive. You need three or more coats of noise-control paint to make a difference, so use the paint on interior ceilings and walls rather than on your roof.
Choose a metal roofing panel that has built-in granules of ceramic and other materials to enjoy a similar noise-reducing effect from your roofing materials. Some metal roofs with embedded materials are as quiet as standard asphalt roofs during rainstorms.
You can also move around furniture and acoustic screens to lower sounds in recording spaces. If you have a taller room adjacent to a loud lower roof (like a roof over a carport), screens and furniture barriers can help deaden the roof sounds without renovating the roof or the walls.
