When looking for a cost-effective solution to your roofing needs, you may want to consider using asphalt roofing shingles. These roofing shingles are very thin and light, making them very affordable and easy to install at the same time. These reasons also make asphalt shingles a familiar and popular way of overhead protection for your property and the people who live inside.
There are two types of asphalt roofing shingles: one is organic and the other fiberglass. Organic shingles are usually made of paper (of the felt variety) and then covered with asphalt. This strengthens the form of the shingle as well as make it water proof. Afterward another coat of asphalt is layered together with granules of ceramic. There are also shingles that are resistant to algae, in which case the ceramic granules have some copper content. This reduces the effects of algae discoloration on top. This process also slows down the growth of moss on your rooftop. Organic shingles have more asphalt than fiberglass, making them heavier. Since they have a paper component, they are also more susceptible to fire.
As the name suggests, fiberglass shingles have a basic layer of fiberglass instead of paper. This makes them stronger but at the same time heavier than organic shingles. The fiberglass layer is wet, with resin made from urea-formaldehyde. This layer is then covered with the same asphalt as the organic one but with additional mineral fillers. This same process also makes the shingle water-proof. One good thing about fiberglass shingles is they are also fire resistant, even netting a class A rating as compared to organic shingles. The fiberglass shingle was came about as a way to replace asbestos, which has been found to be dangerous to the health of installers and even those living under it.
Asphalt roofing shingles generally fare better and last longer in cold areas than in warm regions. This is why we often see asphalt shingles in North America and Europe. Asphalt shingles often get damaged due to thermal shock, which is what happens when there is a sudden change in the temperature of the surroundings. It is also necessary for the roof to have proper ventilation in order to lengthen its life. It is not advisable to install the shingles in cold weather
Installing Asphalt Shingles
Installation of the shingles often starts from the lower corners and then work its way up. This allows the installation to be faster especially if there is more than one person up in the roof. The ends of the shingle should not meet each other; this will only negate the water-proofing factor as it becomes possible for rain to penetrate the lower layer of the roof. Each asphalt shingle should completely cover the edges of the lower layer in order to form a singular structure that will channel water down to the gutter. It is normal to see rows of shingles not lined up against each other as this makes the movement of water more predictable.
