When you are planning to build a house or just renovate the old roof, choosing the right materials can be a little more difficult than you have imagined. After all, the roof is not only the element that protects your house from the weather, but also plays an important role in defining the exterior appearance of the entire house. At the same time, the roof can provide additional space (the attic), and if you built it with quality products, it will prevent heat loss, so you will have a more energy-efficient house and better thermal comfort indoors.
Roofing materials differ from each other by their durability, installation cost, thermal insulation, soundproofing or waterproofing properties. All the characteristics influence the lifespan of the respective roof.
Metal shingles
This type of roof has a lifespan of up to 50 years. Nowadays, metal shingles are some of the most popular roofing materials precisely for their particular durability. They do not allow moisture buildup on their surface, so there will be no moss or algae formation. Metal roofs come in a wide range of shapes and colors able to match any roof type. Such a roof is also highly reflective, which means that it will be very efficient especially during the summer and in warm regions. To be effective in colder climates too, metal roofs must be doubled by adequate insulation.
Ceramic tiles
This material offers greater protection from cold and heat, compared to metal tiles, as well as sound insulation. Ceramic roofs are beautiful and do not lose their aspect in time, but they do develop moss and algae on their surface, so they must be cleaned periodically. A ceramic roof is heavy and requires a sturdy structure to hold its weight. Installations must be done by skilled professionals, but the best news is that it will probably be the only roof you will ever be required to install on your home, considered that it is expected to last even for 100 years.
Standing-seam metal
This type of roofing is increasingly popular. Typically, it is make from aluminum, but zinc and copper are also used. A standing-seam metal roof is very durable and almost maintenance-free. The average lifespan can be up to 50 years, but in good circumstances it might last even longer.
Wood shingles and shakes
They both make some of the most attractive roofs and remain the favorite materials of those who prefer a natural aspect. They are also quite tricky to install, so such a roof is the job for skilled roofing companies northern Virginia contractors and not really suitable for DIYers. Wood is prone to rot and decay and it must be treated against moisture and to enhance its fire resistance. Its average lifespan may not be the longest, but it is not the shortest either – up to 30 years and even longer, if it is meticulously maintained.
Slate
This is probably the most durable roofing material, which is expected to last as long as the house (even two centuries!). Slate is a natural stone, expensive and heavy, therefore such a roof requires a very solid structure and trained craftsmen to deal with installation and repairs.
