Where to Put Screws on a Metal Roof: Benefits & Disadvantages
Metal is very durable, and it can be used to make a variety of roofing styles, from prefabricated corrugated sheets to individual metal shingles. All metal roofing has different fastening requirements, from the type and location of the screws to the number used, but the greatest confusion tends to come from the prefabricated, corrugated sheets. Although there are exceptions, screws should be placed in the flat of the panel, although they can be screwed into the ribs when connecting a seam or if the manufacturer recommends it.
Metal Roofing Benefits
Although most residential roofs are made from asphalt or shingles, metal is commonly seen on industrial and commercial buildings. However, its hardwearing longevity and its unique, industrial appearance mean that it is becoming increasingly popular as a roofing option on homes and outbuildings. The reasons for its increase in popularity include:
When Not to Use Metal Roofing
Although metal roofs are longer lasting and harder wearing than shingles, there are some instances where metal may not be the best choice. This type of material does have certain disadvantages over shingles.
Where to Put Screws
You should always follow manufacturer guidelines regarding the placement and even the type of fastenings used on a metal roof. Generally, this means that the screws should be placed in the flat troughs and not on the peaks or ribs. This ensures a tighter fastening so that the panels will be firmly fixed to the frame underneath. There are exceptions to this rule, however, including when you need to connect the seams of roof panels.
Metal roofs have certain benefits over shingles and other roofing types. They last a long time, have lower lifetime costs than other materials, and are durable. However, they can be noisy unless there is a barrier between the roof and the room below and fewer contractors are skilled and experienced at their installation. If you are installing your own metal roof, follow the roof manufacturer guidelines. This usually means adding screws to the flat trough sections of the corrugated sheets and only screwing into the raised rib sections to connect seams.
