Flat roofs come with minimal slopes so water drains slowly from the area. Although many don’t consider a Flat Roof Portland as the area is rainy, there are situations where a flat roof is the preferred option, especially in commercial buildings. This type of roof is very cost efficient and a flat roof offers easy access. When considering a Flat Roof Portland, you need to understand the various types offered and the benefits of each.
Asphalt build roofs are the most common, but don’t hold up well to the elements. They show signs of weathering in very little time and may leak as a result. In addition, asphalt build roofs are the most polluting and dirty of all flat roof types and installation can be hazardous to workers. This type of roof tends to last for anywhere from eight to ten years.
Cold applied liquid membrane roofs are a combination of polyester and polyurethane resins which are used to create a waterproof, seamless fiberglass enforced roof. Many choose this option when installing a new roof or re-roofing an existing one.
Ethylene Propylene Diense Monomer roofs are the newest roofing type and many are choosing this option as the roofs are heat and UV resistant, weather proof and water proof. Acid rain, chemical solvents and alkalis won’t damage this roof and it is very durable. No maintenance is required other than the removal of tree materials and falling debris and this type of roof may be used on any building.
Rubber roofs are extremely durable and can withstand temperature changes, severe weather, leaks and fire. There are no seams with this type of roof so water exclusion and drainage are never an issue. This type of roof does cost more than asphalt shingles and yet they last longer and they put less pollution into the air. Rubber acts as a good insulator and little maintenance is required.
Turbo seal roofs are made using recycled rubber tires. The recycled tires are applied over tar roofs before being covered with a protective membrane to create a seal that is waterproof. Very few people choose this type of roof in Portland now.
Discuss all options with your roofing contractor. He or she will best be able to tell you which is right for your building. A Flat Roof Portland is an option, but care must be taken to choose the right one.
