Why choose Rob Pression

A gentle and safe method

We don't just wash — we protect the physical integrity of your property.

Improvised methods

Ladders and ropes on the roof: a high risk of breaking brittle asphalt shingles or creating micro-cracks that let water in.

Aggressive high pressure: too strong a jet can tear out window caulking, lift vinyl siding or destroy stucco.

Toxic chemicals: concentrated chlorine or acid strippers that burn the lawn, damage your shrubs and put your animals at risk.

The Rob Pression difference

Drone roof cleaning: no physical contact with your roof. The treatment is sprayed from a distance with precision, so nothing gets damaged.

Soft wash technology: a surfactant-based wash that lifts the grime without violent mechanical force, protecting your walls.

100% biodegradable formulas: our cleaning agents are environmentally sound and safe for your planting and your animals.

I had my roof washed with their drone. It's remarkable watching the machine work from the ground with nobody walking on my shingles, which were starting to crumble. Excellent work — professional and safe!

Ludovick washed our vinyl siding and our big back patio. The work is meticulous. The window surrounds are perfect and the plants around them weren't affected at all. Very polite and efficient!

Great job on the driveway wash and the gutter cleaning. Transparent pricing, no surprises, high-quality work. I'll be calling them back every year without hesitation.

Residential FAQ

Everything you need to know

Does the drone clean my walls too?+

No — the drone is for roof cleaning. For reasons of access and precision close to the ground, exterior walls (vinyl, Canexel, brick) are washed by hand by our technicians with professional low-pressure soft-wash lances.

Are your products safe for my lawn and my animals?+

Yes. We use only certified 100% biodegradable products. On top of that, our technicians saturate all nearby planting with clean water before and after the job, to dilute and protect it.

Do I need to be home during the wash?+

No, you don't need to be there. We just ask that windows and doors are properly closed, outdoor taps are working, and access to the property is clear.

How fast do I get a quote or an appointment?+

Once you send the form on this page, you get a quote or a call within a guaranteed 24 hours. Work is usually scheduled within the week following approval of the quote.

How often should siding or a roof be washed?+

Siding benefits from a wash every one to two years depending on exposure: a shaded north wall soils faster. On a roof, we step in as soon as black streaking or lichen appears — the longer you wait, the deeper the deposit sets into the granules.

Do you work on condos and small apartment buildings?+

Yes — and that's often where the drone helps most: several blocks to cover, projecting glass balconies and residents on site. We give the board a notice to post and aerial imagery of the roofs.
