Getting Ready to Sell the House
Improve the curb appeal of the house
Over time organic debris and environmental stuff just sticks to the roof. This material creates a substrate for stuff to grow on the roof. Small particles of leaves hang on. Oak tree seeds have pieces that can really cling to the grit on a roof. I have a patch of the oak tree catkins (the flower parts) still hanging on the roof and the thunderstorms have not washed them off. So the point is organic stuff does accumulate and stick to a roof.
In this case a customer called to clean the roof so that the house can be put on the market to sell it. Improving the curb appeal of the house so that people would consider the house when they stop by the house or see pictures of the house online. Certainly it can be brightened up with the right roof cleaning process.
When I initially looked at the house there also was a dark mold at the steps on the white trim around the door. So I agreed to clean that section as I was doing the roof. Certainly this would look better since it is the main entry way.
As soon as I started to clean the front of the house I realized it would be easier to clean the steps than protect them from the cleaner so the steps would not be multi colored. The house wash being used so close to the steps made it just easier to clean then so the project changed to roof and stoop cleaning. The big factor was knowing the house may go on the market it would be better to have clean steps. So here are some pictures in progress.
As the cleaner was fully applied you could see through it and see that the steps were getting cleaner
The roof cleaning part of the project was to clean off the roof both chemically and physically. Initially in areas with moss and lose material the roof was brushed to get off anything that would come off with out scrubbing. Here are some before shots to show the moss particularly on the roof of the garage.
The Roof Cleaning
This picture shows the project in progress in actually cleaning the roof. This view is of the treatment starting at the top with a view of how the streaking looks on the house and how the cleaning looks initially.
Cleaned roof prior to rain
The roof has been cleaned in this picture, but it is not completely clean. It does not show up as well in the picture but a dirty, muddy look is still on the roof. What was dark blank has been killed and turns a dull brown. The cleaner is left on the roof so it will do the maximum work possible. Over time it is no longer active from drying out and sunlight exposure. The next couple or rain storms finishes the work of cleaning the surface of any remaining dead organic material.
Final pictures of the roof after a couple of rains. The washing effect of rain helps clear of the dead material still on the roof. The need for power washing is avoided and the roof granules are not loosened so they remain to protect the roofing system and looking good again. This process gets the growth back under control so the roof will look good for a number of years to come.
