The colour you have is the colour you keep
Nothing in the process adds a finish. The shingles are cleaned and treated, and the treated surface is the same shingle, with the same granules and the same colour, that was up there before the visit.
That distinguishes this from a coating or a spray-on restoration, both of which put something new over the roof. Anything laid on top has a colour of its own, and it has to match a roof that has already weathered for years. This does not have that problem because it does not add a layer.
What will look different
The roof should look like your roof, only cleaner. A roof that has been holding dirt, algae and moss will read brighter after the surface is cleaned, and the streaks that follow water paths usually settle down.
That change is cleaning, not recolouring. On a darker shingle it can look quite different from the driveway because the roof is no longer grey with growth. Look at the roof a week after the visit, not in the first hour, when it is still drying.
- Cleaner, with less visible streaking
- Granules sitting tighter on the surface
- No film, sheen or gloss that was not there before
- Water beading and running off rather than soaking in
Why there is no film
A film is what changes how a roof reads. It flattens the profile, catches light differently and, over time, peels. Because the treatment goes into the shingle rather than over it, the roof keeps its texture in sunlight and keeps its shadow lines at the shingle edges.
It also means there is nothing to peel later. The failure mode of a coating does not exist here, because there is no separate layer to fail.
Old stains and growth
The treatment slows algae growth and makes the surface shed water instead of holding it, so growth has less to take hold of. It does not turn a heavily stained roof back into a new one, and we will not claim otherwise.
If the growth is established, what it can do for your roof is confirmed at the assessment rather than promised over the phone. Some roofs need cleaning attention before treatment, and that is decided on the day.
What about faded or sun-bleached shingles
A roof that has spent years in the sun fades on the exposed slopes while the shaded sides stay darker. That unevenness is in the shingle itself rather than in a finish on top of it, so a treatment neither evens it out nor brings back the original tone.
What the treatment does is put the surface back to shedding water, which is the job that matters on a roof of that age. If the colour is the reason for the call, say so at the assessment and we will be straight about what can change and what cannot.
If you want a different colour
This is not a recolouring service, and it is not a reason to treat a roof. If a different colour is the goal, that is a replacement conversation or a different trade entirely, and we will tell you that rather than take the booking.
What a treatment buys you is time on the roof you already have, in the colour it is already in.
