Traditionally, homeowners in general installed asphalt shingle roofs because that was all they know about. Metal roofs were confined to houses designed by expensive architects. Nowadays, metal roofs, especially the standing seam variety, are becoming increasingly popular, even though they cost more than conventional asphalt shingle roofs. If you decide to invest in metal roofs, there are some advantages and disadvantages to consider.
Asphalt shingles and metal roofs
Roofing suppliers in High Wycombe and elsewhere would advise homeowners that price-wise, asphalt shingle roofs are much cheaper than metal ones. However, since the latter are petroleum-based derivatives, prices fluctuate. One drawback is that consistent cleaning of asphalt shingle roofs erases its mineral covering over time, and detracts from the aesthetic appeal of your home’s exterior. If you decide to opt for a metal roof instead of shingles, you can actually install it over the existing shingle roof without removing the former. Professional roofers might advise that you do so, since ripping out the shingles first is bound to be messy, more time-consuming, and adds to labour costs. They will also suggest that you install certain types of material that that helps with ventilation.
Standing seam roofs
Standing seam roofs are a unique brand of metal roofing. Roofing suppliers in High Wycombe and elsewhere will tell you that they come in different shapes and sizes, and installing them requires following a particular procedure. Installing these is thus a job for the professionals. Though these roofs are quite pricey compared to conventional ones, they are far more durable and reliable. Standing seam roofs come in limited colour ranges – forest greens, browns, greys, and red earth – but, like with all metal roofs, you can paint them any colour you want. Metal roofs are also more energy efficient: they reflect sunlight better than traditional roofs, and will keep the interior of your house cooler during summer.
Another advantage of standing seam roofs is that moisture can’t get through, given how the seams are constructed. There aren’t any horizontal seams, as the latter run seamlessly from top to bottom instead. This also means there are fewer seams in the roof. On the other hand, they are tricky to walk on, and become especially dangerous to step on when wet.
When planning to install a metal roof, you should find out from a contractor if they are prepared to install the standing seam variety. Not all roofing companies are keen on doing so because of the higher costs involved, given the low competition rate. Those that do might want to provide their own materials and suppliers, rather than settle for yours.
