Moss, Ice Dams and Heaving Pavers: Richmond Hill Pressure Washing Problems
Ice dams along the eaves of Oak Ridges homes
Thick ridges of ice build along the eaves in January and February, water backs up under the shingles and stains ceilings inside.
Why it happens here: Oak Ridges sits at about 300 m on the moraine, more than 200 m above the lake, so roofs sit higher and colder than most of the GTA, and attic heat melts snow that refreezes at the cold eaves.
What we do: Ice dam removal with a low-pressure steam rig melts drainage channels without chipping shingles, and the crew notes heat-loss spots for your roofer.
1. Road salt
Chloride soaks into concrete pores and leaves white efflorescence. Cold pressure alone will not lift set salt; 200F hot water dissolves and flushes it.
2. Freeze-thaw
Water in mortar and interlock joints freezes, expands and blows out polymeric sand. Cleaning plus a same-visit reseal stops next winter's damage.
3. Shade and humidity
Algae on north walls, moss on walkways and black streaks on shingles. A low-pressure soft wash kills the growth at the root instead of blasting it.

Local knowledge
Wooded Lots and Colder Winters on the Moraine
Richmond Hill climbs from Langstaff near Highway 407 to Oak Ridges, which sits at about 300 m on the Oak Ridges Moraine, more than 200 m above Lake Ontario.
Wooded moraine lots and the shade around Mill Pond keep roofs, decks and north walls damp. We soft wash roofs, restore cedar decks and steam ice dams in winter.
In Bayview Hill and Jefferson, large interlock driveways lose polymeric sand to freeze-thaw, so we clean, re-sand and seal in one visit.
Crews here work from the same hot-water, cold-pressure and soft-wash rigs as every Power Pressure Washing Toronto job across the GTA, with the same written quote per surface and $2M COI.
Written quote per surface before any work. Hot-water rigs for grease and road salt. Fully insured, WSIB compliant, COI in 24 hours.
Reaching Every Neighbourhood Year Round
The city runs north along Yonge Street from Langstaff to Oak Ridges, with Highway 404 on the east side and the 407 at the south edge. Bayview Hill, Jefferson and Richvale are reached quickly off the 404 and Yonge, while Oak Ridges and Elgin Mills sit further north on the Moraine.
In summer and fall, jobs here are mostly roof soft washing, deck and fence restoration and interlock work, grouped by neighbourhood. In winter, the phone is answered 24/7 for ice dams. Our steam rig crews carry fall-arrest gear and work methodically along the eaves to open drainage channels without chipping shingles.
Wooded lots often have long driveways and limited parking. We confirm access, water supply and any overhanging branches ahead of time so the crew can set up safely.
Wooded Moraine Lots, Shaded Roofs and Interlock
The Oak Ridges Moraine gives the city its wooded lots, and the shade they cast keeps roofs, decks and north walls damp. Asphalt shingle roofs grow Gloeocapsa magma black streaks and moss, cedar decks go grey and slick, and stone walks turn green. A low-pressure soft wash handles roofs and siding, and low pressure with wood cleaner restores decks.
Bayview Hill, Jefferson and Langstaff have many newer homes with large interlock driveways and patios. Colder winters than downtown mean more freeze-thaw cycles, blown-out polymeric sand and heaving pavers. We clean, re-sand and seal in one visit to stop the next winter's damage.
Older homes around Mill Pond and Richvale often have ice dam problems from attic heat loss, which our steam rig clears safely.
Colder Winters North of the City
Oak Ridges sits about 300 m up, more than 200 m above the lake, and that height brings more snow load, more ice dams and more freeze-thaw cycles in interlock joints. Ice dam calls peak in January and February. By late spring, shaded roofs show fresh growth and interlock joints show winter damage, so many homeowners book a roof soft wash and an interlock reseal together.

What Local Clients Say
Real jobs, real prices, written quote first.
Andrew B.
Forest Hill
"Our interlock driveway had lost most of its joint sand after a rough winter and weeds were coming through. They cleaned it, swept in new polymeric sand and sealed it with a natural finish, all on the same day. They explained the cure time clearly and roped it off for us. A year later the joints are still tight and the weeds have not come back. The price matched the written quote to the dollar, and they left the street cleaner than they found it. Our neighbours on the next street have since booked them for their own interlock."
Hannah C.
Hoggs Hollow
"Black streaks and moss on the north side of our roof had been bothering us for years. They did not use any pressure on the shingles, just a low-pressure soft wash, and they wet down all the gardens first. The streaks were gone the same day and the moss let go after a couple of rains, exactly as they said it would. The gutters were rinsed out too, and they left photos of the roof from the ladder so we could see the result up close."
Linda M.
Rosedale
"They cleared the salt stains in one visit. Mature maples drop sap every summer, this crew knew exactly which tip to use."

Richmond Hill Pressure Washing FAQs
Do you steam ice dams in Oak Ridges and Jefferson?
Yes. Our low-pressure steam rig melts channels through ice dams without chipping or stripping shingles. Crews use fall-arrest gear, clear eaves and gutters where needed, and note leak-risk areas for your roofer. The phone is answered 24/7 in winter.
Why do Oak Ridges roofs grow moss so quickly?
Oak Ridges sits at about 300 m on the Oak Ridges Moraine, and much of it is wooded. Shade and higher ground keep shingles damp longer, which feeds moss and Gloeocapsa magma. A low-pressure soft wash kills it without stripping granules, and most roofs cost $450-$850.
Do you reseal interlock in Bayview Hill?
Yes. We clean with a rotary surface cleaner, sweep in polymeric sand, activate it and seal in one visit. Full service is about $3.50-$5.50 per sq ft depending on condition, confirmed in writing.
Do you clean cedar decks on wooded lots near Mill Pond?
Yes. Cedar and pressure-treated decks get low pressure with a wood cleaner and brightener, which lifts mildew and grey weathering without fibre furring. A 300 sqft deck runs $200-$350, and fences run $200-$400 per 100 ft.
What causes ice dams on Richmond Hill homes?
Heat escaping through the attic warms the upper roof, snow melts, and the water refreezes at the colder eaves. Steam removal clears the dam safely, but insulation and ventilation fixes stop it coming back. We point out the problem areas we see.
