Metal roofing contractors in Minneapolis would all be experts in installing roofing of any kind (we can hope). However, just like anything else, there is a very precise science and method behind roof installation which many are not quite familiar with.. This is especially the case with metal roofs, which need to be handled differently than basic shingles. So here is our layman’s guide behind how a contractor would install durable, economical, weather-resistant metal roofing.
Just like any major home project, there is a tremendous amount of preparation that goes into a metal roof installation before even one shingle is mounted. For starters, the old roof has to be removed and the rafters checked for damage from natural hazards like termites and water leaks. A safe work zone needs to be set up in the lot where the job is to take place and all the materials—metal panels are just the most visible piece—must be gathered in order to avoid delays. Then, of course, you have to consider replacing the rafters if there is irreparable damage.
Step One: Secure the Edges
But once you get past preparation, things start to move along at a faster rate. The first thing we must do is install edging. In the roofing industry, we call these special panels “eave flashing” and their purpose is to secure the beams around the perimeter. They also serve a special purpose of directing water into the gutters so you can easily direct rainwater (and the snow we get up here) away from the building.
Step Two: Bring in the Big Stuff
Once the eave flashing is installed, metal roofing contractors in Minneapolis will move on to installing the panels themselves. This is the most time-consuming aspect of installation as the panels needs to be amply secured against the rafters using a system of both nails and fasteners. Screws need to be aligned evenly and be separated at least one foot apart going down the rafter. Edges need to overlap as well, both between the panels themselves as well as the eave flashing, which the main panels will sit snugly against. Many contractors will also employ a sealant composed of silicone to deal with smaller gaps.
Step Three: Close It Up
After the main panels are installed, it is time to employ the main flashing. These types of flashes are similar to the eaves flashing, except the metal is traditionally more malleable. This is important primarily because the main flashing is designed to sit on top of sections which don’t have any main panels, such as along the corners. The main flashing closes the roof up and directs water into the main panels and as such requires very careful angling to give the roof full coverage.
And that’s it! Of course, there is a lot more than we can explain here. contact us today and ask about how we go about installing your metal roof with simplicity and speed.
