The anatomy of a roof is complex. However, it’s that complexity that makes it a marvel of engineering that protects everyone living in your home from all the outside elements. It’s also the reason your house is warm in winter and comfortable in summer.
And that’s why a lot of materials go into the construction of the roof. Here, are the reasons to help you to understand better why your roof protects you.
The roof deck is the foundation of the roof and the structure that holds everything together. It is usually made from lumber, plywood and oriented strand board (OSB); or steel, like cold-rolled sections, welded or screwed steel structures or light gauge.
Underlayment is the protective layer between the primary roofing material and the deck. It also serves as the insulation of the interior of the home and is made from some asphalt and bitumen-based materials, like asphalt-saturated felt, rubberized asphalt, bitumen and in some cases non-bitumen synthetic.
Different roofing materials serve as the primary protective cover of the entire property. When it comes to residential homes, roofing comes in a variety of forms which includes shakes, shingles, tiles, and panels made from many materials (wood, metal, asphalt, rubber, fiberglass, organic matter, clay, slate, and others.)
Commercial buildings, on the other hand, are usually flat and use similar materials, but also other forms of cover like bitumen, built-up roofing, synthetic foam, single-plywood, and others.
Fasteners are used to attach the roofing material to the deck and underlayment of the roof. They are from different materials depending on the roofing product. For example, asphalt shingles are fastened with roofing nails, tiles require metal fasteners, while some materials like metal use tar, bitumen or special glue to secure to the roof.
The coating is the last element of the setup of your roof, but depending on the roof material you use it’s critical for the protective ability of the roof. The coating is the leading reason most roofs have an average lifespan of 20 to 50 years because they maintain the integrity of the material. In most cases coating materials are divided by their purpose:
- Fire-resistant coating – used on wooden and natural roof materials to protect roofs from burning in case of fire;
- Wind and weather-resistant coating – used on asphalt and organic roof materials to protect them from getting damaged;
- UV-coating – used on all materials to protect from the harmful effects of sun exposure;
- Ice-coating – used in winter to prevent certain types of roofs from ice damage.
- Organic-coating – used to prevent organic matter like mildew and algae from forming on roofs due to high levels of moisture.
