City policies, permitting requirements, and codes Upcoming events, project https://www.diigo.com/user/ismaelquinn highlights, and announcements on the eco roof blog. Eco roofs weigh from 15 to 30 pounds per square foot roofing Portland saturated, depending on the roof repair Portland vegetation and growth medium used.
The building being considered for an ecoroof must be able http://www.designfloat.com/GraphicDesign/roofing-contractors-portland/ to support this additional weight. For new construction, the additional weight of the ecoroof may or may not require a more substantial structure. Design issues include the building’s foundations, rafters, posts, beams, decking, and other structural elements.
For roofing Portland existing buildings, needed structural upgrades https://www.zotero.org/oliveryoung/items/itemKey/RMFAV8ZD may include additional decking, roof trusses, joists, columns, or foundations.Many buildings already have a 15 gravel ballast roofing repair and are usually structurally sufficient to hold an ecoroof. The following table shows the typical weights of various materials.
Aspect is the compass direction the roof plane faces. An ideal ecoroof in Portland would have a north aspect. North is best to help reduce evaporation and solar exposure, which helps support the vegetation.http://www.stumbleupon.com/stumbler/noeltyler
A north-facing eco roof may not http://youmob.com/mob.aspx?cat=1&mob=http://www.urbanhammer-roofing.com/#!roof-installation-types/cee5 require irrigation. An east aspect is roofing Portland second best. A south or west aspect is least desirable. These would have the most intense solar exposure and likely require greater soil depth and irrigation (unless there is shade). Slope is the angle of pitch of the roof plane.
A2 to 15 percent slope is good for north and east aspects, and a2 percent or less http://www.pearltrees.com/santoscollins slope is good for south and west aspects (because flat slopes have less sun exposure and less need for irrigation). In roofing Portland, most are relatively flat, with slopes around2 percent, although some are as steep as 40 percent.
Slope affects the irrigation, plant material, and materials http://www.folkd.com/user/danmack needed (e.g., lattice to prevent soil sloughing). Modified asphalt, or bitumen, is generally asphalted material that has been improved roofing repair with petroleum-based additives. It is a system that comes in sheets, rolls, and liquid.
Modified asphalt can be applied hot, cold, torched, or self-adhered. It can be laid https://www.bookmarkee.com/dextermendoza loose or adhered to the roof deck. Building insulation is often associated with the ecoroof’s waterproof membrane and is therefore important to consider at the early stage of design.
Conventional roofs save money Eco roofs can last twice as http://www.jodohkita.info/story/77850/ long as conventional roofs, and save money on replacement costs and materials. Properties with may also be eligible for a storm water fee discount.
The City of Portland promotes using on roofing Portland public and https://delicious.com/enriquemike private property to manage storm water on-site. The city offers roof repair Portland building owners and developers an incentive of up to $5 per square foot for an approved project. City also offers resources and technical assistance to property owners, businesses, and roofing Portland professionals interested in getting involved in the industry.
