If you're building your own home, you may be wondering what roofing material to choose. Metal roofs are popular, but what are the advantages and disadvantages? Read on for a helpful overview.
Metal roofs – the advantages
Metal roofing is very long-lasting and is very resistant to damage by insect pests and rot.
Properly installed metal roofing seals your home against the heaviest of downpours and will stay put in high winds, when shingle roofs are easily damaged.
Most metal roofing comes in panels or multiple-shingle sections, making it quick and easy for an experienced contractor to install, saving you money on labour. If you're doing the job yourself, you'll find the materials lightweight and easy to handle.
Metal roofing is a good choice if you live up in the mountains where snow is a regular occurrence. The roofing panels are fitted over thick foam insulation, keeping your home warm while encouraging snow to melt quickly, relieving the weight on the roof.
In hot climates where there's a risk of fire during the summer, metal roofs offer greater safety for your home than wooden shingles, because they are non-combustible. Metal roofing can help to keep your home cool on hot days, as it reflects the sun's radiant heat.
Metal roofs – the disadvantages
Metal roofing can work out more expensive than other materials, although you should save on maintenance costs and the roof will probably never need replacement.
If you crave peace and quiet, metal roofing might not be for you, as it can be noisy during rain or hail storms. It is possible to remedy this by having sound-deadening insulation fitted. In addition, windblown objects and very severe hail can dent the metal sheets.
Metal expands and contracts with the temperature. Although your roof will be secured with metal fasteners, these can still come loose, and on very hot days your roof may take on a temporary wavy effect.
If part of your roof does need replacement, you will have to replace the whole panel, rather than just one shingle, which can be expensive.
Although lightning doesn't generally strike metal roofs, you should protect your home by having lightning protection measures applied by a professional company so that your metal roof is safely grounded.
Overall, metal roofs have many advantages over other forms of roofing material. Consider the overview above, and then have a chat with your local building contractor for more advice before making a final decision.
