The world’s largest green roof recorded in Guinness World Record has had Xero Flor system installed, it is on the roof of Ford Motor Company Rouge factory in Dearborn, Michigan USA, having the benefits of low maintenance  …….

● Over watering is not recommended which otherwise will promote weeds and unwanted foreign vegetation.

● Vegetation mat design deliberately thin to discourage weed growth

No mowing chore

● Sedum selected tend to spread instead of growing tall and therefore no need for mowing/cutting

● If preferred, longer stems could be cut and throw back onto the mat for further propagation

Low weeding chore

● Dense vegetation when fully grown tends to crowd out foreign and undesirable plants, e.g., weeds.

● Weeds cannot grow if moisture content is deliberately kept low (but enough for sedum)

● Removing weeds and undesired foreign plants needed until full coverage if growing on-site,

● Need to check for un-wanted vegetation in the non-vegetated borders

Instant green and year-round coverage

● Pre-grown system offers instant green at installation

● Xeroflor’s customized combination of species (taking into account both client needs as well as local environment situation)

● Provides year-round growing vegetation, with variation in colours and looks,

● No dried-out period (as compared to most other systems)

Low fertilizing needs

● Slow-release organic fertilizer as little as once or twice per year when fully grown

Filtered run-off water

● No loose soil, thus less clogging and blockage of drainage system,

● Less maintenance and repair

● Run-off can be used for recycling purposes

Delayed storm water run-off

● Delay and reduce peak flow and overall run-off volume of rainfall

●  Less demanding on drainage and sewerage systems, lowers maintenance cost and extends service life

Bare patches repair

● Sedum cuttings (sprouts) can be spread to fill in bare spots

● The sprouts will take roots for quick re-covering (no need for fresh plant replacement)

● Wind tunnel tested

● Survived a recent hurricane with gusts up to 160 kmph with no observed damage nor loss of vegetation and soil

● Passed fire resistant test

● Mat materials and components, though not bio-degradable, are inert and long lasting. Very little impact on  the environment

●  No replacement needs

● Over 8 years in the case of the Ford Rogue Plant in the US, and many others

● In Europe, Xeroflor sedum systems are known to have been performing satisfactorily for over 30 years

Extended service life of roof

● Less stress (heat, uv, etc.) to roof materials and finishes, reducing maintenance cost and repair

● Experience in Europe showed doubling of life span of roof material and structures

Easy access for roof repair

● Access by removing relevant portion of the vegetation mat

● Replacement of the same piece of mat after repair – no need to re-plant or re-grow.

● Built-in detection system, if implemented, helps in accurate location of potential and actual leaks
 

Precautions for cold regions

● Check and winterize irrigation system (if any) in cold weather regions

● Not a problem in the tropics

Maintenance offer

● First year maintenance FREE,

● Extended maintenance service plans available
