Different Kinds of Roofing
Whether you are looking to replace your roof, install a new one, or simply make a few modifications to your home, there are many different choices that are available to you. From asphalt to polyurethane foam and even wood shakes and shingles, there are options that are right for your needs.
Slate roofing is one of the oldest and most durable types of roof materials. Everett Roofing makes it an excellent choice for a traditional home. However, slate roofing is not the cheapest material, so be sure to consider your budget before making a decision.
The most popular color for a slate roof is gray. Other colors include black, blue, and purple. In addition to being weatherproof, slate tiles are fireproof.
A well-laid slate roof should last for several generations. It may require maintenance work after the first few decades, however. Some companies offer warranties to cover this type of service, but not all warranties are transferable.
Another feature to look for is a company that can properly install a slate roof. Some inexperienced roofers may install tiles improperly, or mismatch the colors of new and pre-existing tiles.
Although it is a bit more expensive than other roofing materials, a well-maintained slate roof can last for decades. One of the best things about slate is its low water absorption, which allows it to withstand frost damage caused by ice.
To get the most out of your slate roofing endeavor, you should know a thing or two about how this beautiful material is made. Luckily, the process is simple.
A slate roof may cost more than asphalt shingles, but it is worth the extra expense. Slate roofing is also environmentally friendly, as it is made of all-natural materials.
Asphalt roofing shingles are among the most popular types of roofing. They are available in a variety of styles and colors and have a long history of protecting homes. While asphalt shingles aren’t the longest-lasting or the strongest, they are inexpensive, easy to install and require very little maintenance.
In the early 19th century, asphalt was used to waterproof duck fabric. It was later used to impregnate the fabric and seal it to the roof.
Today, most asphalt in the States is used for paving and roofing. In fact, four out of five homes in the country have some type of asphalt shingle.
Shingles have a wide range of uses, including roofing for residential and commercial buildings, and they are made to protect against extreme weather. Many varieties are treated to resist hail and algae growth and to reflect sunlight to cool a home.
Asphalt shingles are the most economical type of roof available. The price varies, depending on the labor costs in different regions. Some asphalt shingles have a lifespan of 20 years or more, while others are only last about five.
In 1953, the self-sealing asphalt shingle was introduced. These products are more effective against damaging hail. However, they are not as effective against severe storms.
Besides the self-sealing shingle, there are other asphalt roofing innovations. For instance, there is a dimensional asphalt shingle, which is designed to last about 30 years.
When it comes to insulating a flat roof, nothing can compare to the benefits of polyurethane foam. The science behind the product is simple, yet effective. It also offers flexibility and a long-lasting coating. Polyurethane foam is widely used in modern refrigerators.
Before the invention of spray polyurethane foam, other methods of incorporating asphalt into polyurethane had been attempted. However, the products from these methods were friable and lacked sufficient compressive strength.
One method involves blending soft asphalt with polyurethane precursors at low temperatures. This produces a uniform, asphalt-polyurethane foam product that has good compressive strength and cell structure.
Another method is to use the NASA blend of polyols. These polyols are light in weight and combine the advantages of insulation and durability.
During the foaming process, carbon dioxide gas is evolved throughout the cell structure. Because of the reaction between water and polyisocyanate, the carbon dioxide bubbles create cells that are characteristic of the polyurethane foam.
Spray foam roofing is a relatively inexpensive and easy method of reroofing. Unlike other roofing systems, it can be applied over existing concrete, asphalt, or metal roofs. Typically, it is sprayed at a thickness of one inch, making it perfect for insulating a flat roof.
Spray polyurethane foam is becoming increasingly popular in the states for insulating commercial buildings. Unlike other types of spray foam, it is not only resistant to wind uplift, but it also offers exceptional resistance to moisture, a major concern for building owners.
