This is most likely due to sudden changes in temperature and humidity levels. It's pretty common, and not much of a cause for concern. Nighttime creaking comes as a byproduct of warmed roofing materials cooling, and thus constricting slightly. The action is harmless, but creates a soft creaking sound.
When the wind is blowing against your roof or your attic side walls, the pressure of the wind is causing the wood framing to flex. The wood sheathing could be rubbing against the trusses, and the noise could be from wood rubbing against metal fasteners.
Note what time of the day you hear the noises. If it's in the morning or evenings, squirrels and birds are the most likely culprits. Bats, raccoons, mice and rats are nocturnal, so you'll most likely hear these animals at night. A loose attic vent or shutter on a window can make a banging noise in the wind.
It's thermal expansion and contraction. The sun hits your roof and heats it up. As the lumber expands, it moves, and it will rub against other pieces of wood that aren't moving at the same rate. This movement creates the popping noise.
But in severe wind storms, it's normal for a house to make a few noises. As to what's causing the problem and the noise, it's pretty simple. When the wind is blowing against your roof or your attic sidewalls, the pressure of the wind is causing the wood framing to flex.
Expansion and contraction of the building materialsAccording to physics, when matter is heated it expands and contracts when cooled. When the temperatures are low, the exposed building materials will rapidly shrink causing the noises as they rub against one another.
Creaking and Popping in the NightThe many materials that make up your house — wood framing, plywood, glass, metal ducts, nails, plumbing pipes — all expand and contract at different rates. When a house cools at night, these materials may move slightly, rubbing against each other and making noises.
A. Your house is talking to you, and you are getting only some of it. The wood is expanding when it warms up, as in the spring, and contracting when it cools off, as in winter. This is all natural and harmless.
In simple terms, the polycarbonate structure acts like a drum to give a loud but 'tinny' high frequency sound when hit by rain which tends to be irritating to the human ear.
Polycarbonate is a very strong and resilient thermoplastic material. Polycarbonate is also very lightweight and capable of withstanding extreme temperatures, either hot or cold. Due to these qualities it makes for an effective roofing material for many applications.
Polycarbonate is a transparent glass-like soundproofing barrier. It transmits 95% of the light through it. Polycarbonate sheets are installed on fences or areas where you want to block the noise. They can be fixed on solid flames like wood, plastic, steel, or any other materials.
Fortunately, you can use the following measures to silence your metal roof.
- Use Proper Fasteners. The fasteners secure the roof material (in this case, the metal) to the roof deck.
- Use Adequate Insulation.
- Use Suitable Underlayment.
- Overlay the Metal.
- Use a Raised Profile.
- Use Thick Metal Sheets.
- Use Textured Metal Sheets.
Loud Rain
- Installing a shade cloth over the roof to dissipate the force of the rain before it hits the roof surface.
- Installing extra insulation on the roof.
- Installing equipment such as solar panels to dampen the sound.
Although typical techniques of soundproofing will not function or be suitable for a conservatory, it's possible to reduce sound ingress and egress notably. There are soundproofing solutions for your conservatory from Ideal Homes Ltd that preserve the look of a yard space, but still keep noise pollution to a minimum.
Draw your curtains or blindsHeavier curtains are the most effective at reducing noise, but are often not the first choice when it comes to conservatory window furnishings. Even thinner curtains and blinds can help reduce noise slightly, or at the very least can put the noise producers out of sight and out of mind!
"Sometimes known as solar reflective paint, anti-glare paint is a solvent based resin paint that can be applied directly to glass, polycarbonate or even plastic to reduce the sunlight that gets into your conservatory.
The main disadvantage of polycarbonate is that it isn't resistant to scratches. For example, if a branch should happen to fall on a patio canopy made of polycarbonate, it may be scratched. This problem can be solved by polishing the polycarbonate.
Can I walk on polycarbonate roofing? No, do not walk directly on polycarbonate sheets. Polycarbonate sheeting is not intended to support the weight of a person. Use stepping ladders or place crawling boards between two or more rafters to create a path for walking.
When the polycarbonate is attacked by the UV, it changes color and starts to become yellow. This phenomenon happens because the connections between the polycarbonate molecules lose their strength.
Cleaners such as Windex or 409 will harm your new piece of polycarbonate. Use only products specifically recommended for cleaning polycarbonate such as Novus #1, or Brillianize, and a soft cloth. (All are available in our showrooms and OnLine). Never use a dry cloth or your hand to clean your polycarbonate!
Polycarbonate is stronger than acrylic. Polycarbonate has 250 times the impact resistance of glass. Acrylic is very rigid whereas polycarbonate can be bought in flexible grades. Acrylic cracks more easily than polycarbonate under stress.
