Is metal roofing right for you?
Metal roofing isn’t anything new for homes out in the country. They’ve been putting them on barns or years, and over time, they started re-roofing their homes with them too. Now, homeowners in the city and suburbs are going with metal roofing. It isn’t like hailstorms, and high winds only hit the country’s rural areas, right?
Still, not everyone is convinced they want to go with metal roofing because they have some questions about the product. The biggest concern for many is, “Do Metal Roofs affect cell phone reception?”, cause well all know that today, nobody can live without their cell phone, right?
Businesses and homes both can have some great enjoys metal roofing, with a big one being they are fire-resistant and energy-efficient. However, there are some circumstances where cell phone reception is disrupted when the user is under a metal roof. This is something that has a workaround, though.
How Cell Phone Reception is Affected By Metal Roofing
Let’s clarify one thing: Metal roofing does not interrupt cell phone reception. What they do though is amplified any existing disruptions, like utility towers. When metal roofing interacts with something that interrupts, it creates a shield of sorts, which blocks RF signals (radio frequency) cell phones use that.
Don’t let this issue hinder your decision to enjoy the metal roofing benefits that you could be using. We have found some suggestions that can help you get better cell phone reception once you you’re your metal roofing installed:
Best Option: Install a repeater system. With this system, you will get an antenna, broadcaster, and signal amplifier. Place the antenna on your roof where it can get RF signals. It will pass those signals to the amplifier, which should be installed somewhere that is out-of-way, like the attic. The signal will go from the amplifier to a transmitter that communicates with your cell phone.
Second Option: Install a Cell Phone Signal Booster, which is typically available from your cell phone carrier. A disadvantage of going with this option is that it must be plugged into your phone. So, if you’re not plugged in to it, your phone isn’t benefiting from it, which takes away the convenience of a portable phone.
Do metal roofs make the house hotter?
It depends on two variables. Heat absorbency of metal roofing is affected by the color and finish. Yes, as metal is exposed to the sun, it will heat up – but not any more than any other roofing material.
Choose a color and finish that is heat reflective and will be just as cool in the summer as other roofing materials. Metal roofing is lighter weight than other roof materials. So, while it will heat up faster, but not any hotter though, it will also cool down faster too.
Another variable to consider with metal roofing is directly below it. If the space just under the roof in the attic, you can control the heat by having attic vents installed. Proper ventilation in the attic keeps it close to ambient air temperature and gives metal roofing with insulation the best chance to keep the rooms below from getting heat from the ceiling.
Do Metal Roofs leak?
Metal roofing offers durability, performance, and strength that other roofing materials don’t, but that doesn’t mean they aren’t without problems. The problems, however, stem from poor installation. Six common things that cause metal roofing to leak:
Most leaks with metal roofing are the screws used during installation. They have rubber washer that seals the hole, but if that rubber goes sideways, it could leak. It can go sideways because of too much torque applied, or not enough torque was applied, the rubber washer never sealed.
The screw may have gone in at an angle or missed the strut it was meant to go in. The rubber will dry out over time as it is exposed to the elements, which is why an annual roof inspection is important.
Metal roofing flashing is prone to be the culprit of leaking around the vent stack flashings for the air vents, HVAC vents, and plumbing pipes. Stack flashing waterproofs these pipes and vents typically is a rubber or rubber-like material that forms a seal over the metal roofing and squeezes around the pipe or vent to form a seal.
As the metal roofing contracts with the heat, the rubber contracts with it, but after a time of being exposed to the exposure, it can become worn and need replacing. Another reason annual roof inspection is needed.
Metal roofing sealants that are installed in concurrence with a metal roof seldom last as long as the metal roofing and will need replacing during an annual metal roofing inspection. We find these sealants metal ridge caps, Z flashings, counter transitions, roof transitions, reglets, and pitch pans. There is a metal roof sealant that is specifically made for metal roofing, you may also use a silicone caulking, but if the metal roofing has been painted, it usually won’t adhere.
Metal roofing with an HVAC system installation will be placed on curbs and must be done by a professional HVAC technician that knows how to work with metal roofing. The room for error in this installation is little to none.
There is an uphill side, two upper corners that are challenging areas. Water gets trapped behind the HVAC unit and puddles there, behind the flashing, eroding the sealant, then the metal roofing leaks. Caulking or sealing that area will only make worse. To fix it properly, the metal paneling where the HVAC system is installed has to be removed, which means the HVAC system has to be disconnected.
Overlaps and Seams
On metal roofing, where two pieces overlap has had a capillary draw, meaning it leaks. A capillary draw happens when water travels up between two pieces that are tightly joined. This can be remedied by applying butyl tape or sealant between the two pieces. However, if they are not applied correctly, the leak could be worse.
Is a metal roof worth it?
Yes! Just a look at the benefits metal roofing offers:
- 50+ years life expectancy
- Beautiful styles
- Interlocking panels
- Fire resistance
- Energy efficient
- Low weight
What is the best color of metal roof for energy savings?
As we discussed earlier, there are several variables when it comes to energy-efficient roofing. Attic ventilation and insulation are the primary factors and color will make very little difference. Then again, it depends on what part of the country you’re located too.
Typically, in the southern part of the country where the summers are hotter than the winters are cold, going with a light-colored metal roofing is recommended. For houses in the north, where the winters are colder than the summers are hot, we recommend dark metal roofing. Today, metal roofing and trim come in a variety of colors, making it easy to choose the best match for your house.
Metal roofing has been around forever, or so it seems. It has withstood storms of all types and keeps on giving. It has houses hay, horses, cattle, and farm implements. It is a material that many homeowners have trusted for years and will most likely still be on your roof when you are no longer in the house.
