Roof Soft Wash in Southlake
A Southlake roof is rarely one surface. It is several planes at several pitches, cut up with valleys and dormers, and that means several setups rather than one pass. The pitch is also the reason nobody should be standing on it.
Black streaking is algae feeding on the limestone filler in the shingle, and it comes off with chemistry at low pressure. Pressure would take the granules with it, and the granules are the part protecting the roof, so force is the wrong tool on any composition roof. On a steep multi-plane roof it is also the wrong place to be standing.
What makes this a Southlake job rather than a generic one is reach. Each plane needs its own approach, and the far ones are past the length of a single setup. That is time rather than difficulty, and it is the honest reason a quote here is not the same as the same roof area on a simple hip.
The pattern to expect afterwards is the same everywhere but worth saying: the roof keeps improving for a few weeks. The organism is killed on the day and it weathers and rinses off after, so a roof that looks eighty percent better when we leave is not finished, it is still working.
While we are set up we will tell you what we can see of the valleys and gutters. On a cut-up roof that is where debris collects, and a packed valley holding water is where the next streak begins.
What we do differently in Southlake
- ✦Several setups quoted, because a multi-plane roof is not one pass however the square footage reads
- ✦Chemistry at low pressure, since pressure strips the granules that protect a composition roof
- ✦Nobody walking steep planes, which is a safety answer and a roof-life answer at once
- ✦Expect it to keep improving for weeks after, as the killed growth weathers off
- ✦Valleys and gutters reported on while we are up there, as that is where the next streak starts
Questions
Why is my roof quote higher than my neighbour's for a similar size?
Setups, usually. A cut-up multi-plane roof needs several, where a simple hip needs one. Square footage alone does not tell you how many times we have to move and reset, and that is most of the day.
It still looks streaky in places when you leave. Is that normal?
Yes, and it is worth knowing in advance. The algae is killed on the day, then it weathers and rinses off over the following weeks. A roof that looks much better when we go is still improving. If something has genuinely not moved after a month, call us.
