Roof Cleaning Birmingham
How do you clean moss from a roof?
Our roof cleaners use two systems Low Pressure Wash or Softwash Roof Cleaning.
The unit we use for roof cleaning is set at a lower pressure than your standard pressure washer as all we need is the dirt and moss removed from the roof. The inhibitor treatment will kill any residual biofilm and continue to clean the roof for the follow 12 months.
There are certain roof tiles (Rosemary Clay Fibre Cement) that do not benefit from low pressure cleaning so for these roof tiles we would recommend softwashing but we would advise which is the best solution to clean the property roof.
Low Pressure Wash Roof Cleaning:
Pros: Same day clean-night and day results.
Cons: Messy Job and there is always the chance of a water leak.
Softwashing is scraping the roof removing the bulk of the moss before applying a premium inhibitor treatment some roof can be treated with a cleaner if a quicker result is required.
Softwash Roof Cleaning:
Pros: The works are not as messy as pressure washing. There is no chance of water leaks.
Cons: The product can take up to 1 year to work. Roof only look a little better on the day of the clean.
Low Pressure Roof Cleaning:
Cleaning is carried out in two stages:
1) The roof is washed using our low pressure jet wash which removes the bulk of visible dirt lichen and moss. The roof is then rinsed of alldebris before the next step.
2) The second stage is the application of a premium inhibitor (residual cleaning properties) at the correct dilution rate according to themanufactures instructions killing any residual spores.
The application of the inhibitor is essential as it will slow the regrowth of moss lichen etc a reasonable expectation is that the roof surfacewill be biofilm free for 18-36months before a second treatment is required.
Roof Cleaning Work Sequence
Arrival on Site: This is normally 8am. We will contact you afew days prior to our arrival. The weather candelay roof cleaning but we would alwaysadvise you if we could not start works.Works can last up to 3 days depending onthe roof size.
Happing Up:The property is happed up to protect thecustomer garden and catch the moss. Downpipe filters are also fitted. It may necessary tohap your neighbours garden depending onthe proximity to your property. Roof cleaningcan be a messy job so all garden furnitureplant pots etc. should be moved away fromthe house. It is advisable to move any carsfrom the driveway (neighbours may need tomove their cars) It is always wise to adviseneighbours of the proposed works.
Low Pressure Wash:The roof is washed from the top down. Thework is never rushed. Once the roof is free ofmoss it is rinsed.
The Clean Up:Gutters are cleaned out and filters removed.The moss is collected into bins for removaloff site. The building is rinsed down from thetop facia soffits wall windows doors removingany overspill. The ground area is also rinsedleaving the area clean and tidy
This system can take up to 1 year to fully clean the roofbut results should be seen within a few months. We use a professional concentrated cleaner forremoving natural growths such as moss spores algae or mould from roof tile surfaces.
Benefits:
- Does not require rinsing.
- Treats roof tile surface with no risk of staining and damage.
- Contains no acids or bleach.
- Can also have some residual benefits.
The moss is normally always cleaned from the gutter level with telescopic tools unless scaffold is erected. The downpipes are protected against blockage beforehand. Tarpaulin is laid to receive the falling debris and gutters are cleaned out before the biocide isapplied.
