Many homeowners choose metal roofs because they want the outstanding performance expected from these types of roofs. However, it's important to make sure that the roofing panels installed on your home are installed by a professional roofing contractor because mistakes can be made with the fasteners, depending on the type of slope your roof has.
Problems with Low-Sloped Roofs
One of the reasons why moisture problems are more common with low-slope roofs is that water and ice slide off of high-sloped roofs much more quickly. In contrast, with low-slope roofs, water remains on the roof for a longer period of time and has more time to seep into your roof.
How Fasteners Work
The fasteners are the objects that penetrate the metal panels and the substructure to hold the metal panels in place. These exposed fasteners are considered to be more economical than the standing seam solution.
The Side Laps
With lower-sloped roofs, one of the issues you need to worry about is the exposure of panel fasteners. This most often occurs with an incorrect panel profile selection and panel side laps. With the side laps, it's important to put a sealant in place so you can avoid an issue known as capillary action. This is a problem where water siphons up the seam to the building envelope.
The Panel Profile
It's important to take into consideration the panel profile. The height of the ribs of the profile does not matter very much, but the shape of the ribs does matter because how the profile bends can have an anti-siphoning effect.
Why Your Home Needs a Metal Roof
Fortunately, if you choose a roofing contractor who has experience with residential metal roofs, you will not have to worry as much about these problems. Fortunately, a growing number of roofing contractors know how to install this type of roof because of how popular it is.
One of the reasons why the popularity of metal roofs is soaring is because of how long-lasting they are. While asphalt roofs are affordable, they are also made out of materials that don't last as long as metal roofs unless you choose the more expensive premium types of asphalt roofing shingles.
Compared to more traditional roofing materials such as concrete tiles, metal panels are lighter. This makes them easier to work with, and they will also place less strain on your roof. Despite this, they can be highly durable and hold up against strong weather.
