Which is better, shingle or metal roof?
One of the most important components of your shed is the roof. A good roof will last for decades and protect your building and whatever you are storing from the elements that nature throws your way.
We have two main options when it comes to roofs: shingle or metal.
Lets explore each one.
Ever since we started building barns 30+ years ago, the shingle roof has been our most popular roof. Over the years, the 3-tab shingles have given way to the heavier and better looking dimensional shingles that we use today. There is a good chance that your house has dimensional shingles because it is the most common shingle for today’s houses.
For shingles to get their full potential life, they must be applied on a stable surface. We start with full 1/2 inch OSB (oriented strand board) sheathing. We use OSB because it is stronger and more uniform than plywood. OSB also will not bow between the trusses like plywood can. We also use H-clips between each truss on the horizontal seams. The H-clips keep the two sheets from moving independently in the case of snow load or walking on the roof.
We also use metal drip edge along all edges of the roof to protect from moisture running back under the shingles. Finally, the lifetime dimensional shingles are applied per manufacturer’s specs for a handsome, long lasting roof.
Metal roofs have long been used for agricultural and industrial applications and more recently it has seen a growth in popularity in residential applications.
We use trusses at 24″ on center under our metal roof (not 4′). On top of the trusses, we use 2×4 purlins (not 1x or 2×3). Before we install the metal, we use foil bubble insulation. This insulation is to keep the metal from quick temperature changes that produce condensation. Our metal has Kynar 500 paint that has a 40 year warranty.
So which will it be? Either is a great choice. The metal holds up a bit better in high winds. The shingle roof may be a bit more air/insect tight. Both will give you decades of service.
In most cases, it comes down to which you like the looks of or which fits into your surroundings the best.
