Roof Cleaning & Moss Removal in St. George, Ontario

D&D Home Services offers roof cleaning in St. George, including assessment of moss, algae, lichen and surface staining. The roof material, condition and access determine the suitable cleaning method. Cleaning and roof repairs are separate work. Call (519) 501-5003 for a free quote.

Roof pitch, height, roofing material and access all affect the work being considered. Cleaning and repairs are separate questions: visible staining does not establish the condition of the roof beneath it.

What We Remove from Your Roof

Moss

Moss can hold moisture around roofing surfaces and conceal the condition beneath it. We assess the roof material and visible growth before selecting treatment. Pulling or scraping tightly attached growth can disturb a damaged surface, so removal needs a suitable method.

Gloeocapsa Magma (Black Streaks)

Dark streaks may be associated with algae, but their appearance alone does not diagnose the roof's condition. Cleaning addresses suitable surface growth and staining; it does not replace checking damaged shingles, flashing or a reported leak.

Lichen

Lichen adheres firmly to a roof surface, so its treatment and removal must take the roofing material into account. It should not be treated as loose dirt that can simply be blasted off. The assessment sets realistic expectations for the cleaning result.

Bird Droppings + Debris

Leaves, twigs and localized deposits can collect in valleys and shaded areas. We identify the affected roof sections and nearby drainage when defining the work. Cleaning those areas is separate from repairing roofing or unblocking buried drains.

Why Roof Cleaning in St George

St. George notes

Roof cleaning in St. George: busy older rooflines and shaded slopes

Older Victorian-style houses have busy roofs, with steep pitches, gables, dormers, chimneys and valleys. If your St. George house is one of them, walk around it and look at each valley and each shaded face. Every place where two slopes meet holds leaves and moisture, and moss starts there. The pattern shows where damp is doing the work, and it tells us where to begin.

Check what the roof is made of before you book. A slate roof can crack underfoot, cedar shakes can be soft, steel can scratch, and asphalt sheds granules. Each calls for its own method, and a roof that is old or brittle may not suit cleaning at all. We look at the material and the age first, and if walking on it could cause damage, we say so and suggest a roofer look first.

Southern Ontario summers are humid, and that feeds algae and moss on shaded slopes. Cleaning is a gentle wash with a cleaning product, done on a dry day between spring and fall, and strong pressure is left out because it can strip granules. Steep pitches and chimneys call for Working at Heights certified crew and dry footing. Roof cleaning is separate from repairs, and a cleaning visit does not fix leaks.

What we plan for in St. George

Valleys and dormers: we start where slopes meet, since leaves and damp collect there and moss begins.
Material: we identify slate, cedar, steel or asphalt before we pick a product.
Roof age: we check how worn the slates, shakes or shingles are, and tell you if cleaning would do more harm than good.
Chimneys and flashing: we note the metal and masonry around them, and keep runoff off old mortar and paint.

Questions from St. George homeowners

Our old roof has a lot of gables and valleys. Does that make cleaning harder?

It makes it slower. More valleys and dormers mean more places for debris to sit and more careful work around edges. We clear loose material by hand before washing, and plan access around the pitch. The quote reflects the extra time, and it will say if any section is unsafe to reach.

There is a brick chimney on our older house. Is that a problem for roof cleaning?

It needs attention, not avoidance. Chimney mortar and flashing can be fragile, so we keep the wash gentle and run rinse water away from old joints. Loose flashing or crumbling mortar is a repair, not a cleaning job, and we will point it out. A mason or roofer can deal with it first.

Roof Cleaning Questions in St. George

What the work includes, how it is carried out, and what affects your quote.

How much does roof cleaning cost in St. George?

Roof area, material, pitch, height, access and the amount of growth affect the quote. Photographs from a safely accessible position help explain the concern. The roof and suitable method must be assessed before agreeing a price and scope.

Will cleaning affect my shingle warranty?

Warranty requirements depend on the roofing product and its manufacturer. Check the actual roof's care and warranty instructions against the proposed cleaning method before work begins. A general claim that one method preserves every warranty is not enough.

How often should a roof be cleaned?

There is no single interval for every roof. Material, shade, tree debris and previous growth affect the need for attention. Use visible condition and the manufacturer's care guidance; cleaning should not substitute for assessing a leak or damaged roofing.

Is the treatment safe for plants and pets?

The selected product and application require specific precautions. We review nearby planting, drainage and access and explain what must be protected or kept clear. Follow the instructions given for the job rather than assuming any cleaning chemical is harmless.

Does cleaning repair damaged shingles or leaks?

No. Cleaning addresses suitable surface growth and staining. Broken shingles, failed flashing, leaks and deteriorated materials need separate assessment and repair. Tell us about known defects before a cleaning method is agreed.

Do you offer roof cleaning in St. George?

Yes. Send the St. George property address, the known roofing material and photographs taken from an accessible position. The team will confirm assessment, access and the proposed work. You do not need to climb onto the roof to request a quote.
