Residential Metal Roofing: Is It Right for Me?

When the contractor delivered the sad news that my roof needed replacing, that led to a discussion of material choices. I was surprised to hear that metal roofing was an option. Sure, it was fine for commercial buildings, but a home? My contractor told me that metal is used for homes more than people realize. The panels can be designed to look like just about any type of roofing you can imagine. After looking at some samples and finding out about the long life of metal roofs, I decided to give it a try. Fifteen years later, my roof is still in great shape. If you are facing a roof replacement in the near future, let me tell you more about metal roofing. I'm betting that you'll decide this solution is right for your home.

Residential Metal Roofing: Is It Right for Me?

What Causes Your Roof To Creak, Groan And Bang

by Kelly Murphy

Houses make all sorts of noises no matter how old they are, and though many explanations involve things that don't really require urgent care -- such as your house "settling" -- you may need to have your roof inspected for damage or possible fortification. Believe it or not, even loud noises are normal for many houses, and can come as a result of a number of factors, such as the temperature outside.

Temperature And Humidity Changes

If you notice that your house tends to make a lot of noise as the seasons change, it's probably at least partially due to a shift in temperature and humidity. When winter hits and the air gets dryer, the wood in your home loses its moisture and contracts a little. Conversely, once it starts getting warmer -- especially in Spring with extra rain -- the wood will start to expand again. The important thing here is that not everything in your house moves; parts protected by insulation, such as your walls, typically don't move. Your roof, which is exposed to the elements, will move more.

Loud popping sounds come from metal joints popping as stress is relieved. This is typically nothing to worry about, as while your roof is constructed to be sturdy and firm, it is also designed to account for minor shifts due to the weather.

Low And High Wind

In high winds, it's natural for your house to creak and groan a little. Houses aren't exactly aerodynamic, and if you've ever tried carrying a piece of flat wood in the wind, you'll know how easily the wind can push you. As wind hits the walls it will cause the house to move ever so slightly, especially if the wind is powerful. Your roof will often bear the brunt of this given its size and because it essentially holds the top of the house together.

If your roof makes a lot of noise in low wind, however, it may be necessary to have some repairs done. Your roof should not be so loose that minor winds cause it to move too much, because this can cause the wood trusses and sheathing to rub up against its metal fasteners. If this is the case, the trusses probably need additional support and reinforcement. This doesn't necessarily mean any major damage to your roof, but it does mean that it should be strengthened before any major damage can occur.

Water Damage Or Termites

In some unfortunate cases, your roof can start to creak and groan due to its structure weakening. If you have a roof leak, prolonged moisture damage can soak the wood beams and cause them to bend more easily. Along the same lines, a termite infestation can cause the same weakness problems, though termite damage will make the wood more likely to snap.

This weakness is often accompanied by sagging in the affected areas, so if you do see roof sagging, call a repairman from a place like Homestreet Roofing Inc immediately. Even if you don't, an inspection is a good idea when you want to play it safe. If you catch the problem early, you probably won't have to have your entire roof replaced, and will only need the affected wood beams replaced and possibly reinforced.
