Roof maintenance starts with regular inspections by the homeowners. These help identify signs of wear or deterioration in time and allow you to plan necessary roof repairs. It’s a simple but crucial habit that lets you quickly spot structural weaknesses, early signs of leaks, or moss buildup on the surface.

How often should a roof be maintained? Creating a Roof Maintenance Plan

Inspect or hire to inspect your roof at least once a year, ideally in the spring after the snow melts or in the fall after leaves have fallen. Inspections are also a good idea after severe weather events like storms or strong winds, which can lift asphalt shingles, displace flashing, or damage sealants.

What Should Homeowners be Looking For?

Key signs to watch for during your inspection include:

• Cracked, lifted, or missing shingles—especially on sloped roofs

• Dried out or deteriorated flashing joints around chimneys, skylights, and vents

• Moss or mold growth, especially on shaded or poorly ventilated roofs

• Debris clogging the gutters

• Sagging areas or visibly warped roofing surfaces

DIY or Professional Roof Maintenance Services?

A personal inspection is a good starting point but doesn’t replace an expert’s evaluation. Professional roofers have the tools and experience to detect hidden issues, like attic moisture or membrane separation. They can also recommend maintenance services tailored to your roof type.

How do I take care of my roof? 

Proper cleaning is vital for preserving your roof’s integrity. Though often underestimated, this step is the best way to remove factors that promote moisture retention and accelerate deterioration.

Why Clean Your Roof?

Over time, debris, dead leaves, dust, algae, and moss build up on your roof. Not only are they unsightly, but they also block proper water drainage. A poorly cleaned roof retains moisture longer, which speeds up material wear and can lead to leaks or loss of insulation.

Regular cleaning extends the lifespan of your roofing material, especially asphalt shingles, which are more sensitive to humidity fluctuations. It also helps preserve the building’s appearance and better protect the structure against moisture.

What Cleaning Method a Homeowner Use?

Avoid high-pressure washing, which can damage the surface and shorten the roof’s life. Instead, clean by hand using a soft-bristled brush and a biodegradable cleaner. Rinse with low-pressure water to avoid damage. Installing zinc or copper strips can help prevent moss regrowth—an eco-friendly, long-term solution.

Safety First

Climbing on a roof is always risky. Use non-slip shoes, a secure ladder, and only work in dry conditions. Ideally, have someone with you. If your roof is steep or you’re unsure, it’s best to leave the job to professionals who can clean your roof safely and efficiently.

Snow Removal: A Critical Winter Task

Quebec winters are harsh, and heavy snow buildup can strain your roof, especially flat ones. That’s why snow removal is essential to seasonal maintenance.

What Are the Risks of Snow Accumulation?

Excessive snow puts major pressure on your roof, which can lead to sagging or even collapse—especially on older homes, garages, or sheds. Ice dams can also form, blocking water flow and causing leaks beneath the surface.

What Are Good Snow Removal Practices?

Clear snow when accumulation exceeds 60 cm (24 in), or if you notice signs of ice dam formation. Use a telescopic roof rake with a plastic blade to avoid damaging the surface. Never scrape down to the roofing material. If your roof is hard to access or you feel unsafe, hire professional snow removal services.

Gutter Maintenance: Prevent Leaks

Gutters play a crucial role in preserving your roof. They divert water away from the structure, preventing water buildup that can damage materials. Poorly maintained gutters can quickly lead to serious problems like leaks, wall deterioration, weakened foundations, or mold growth. That’s why gutter maintenance is key to any good roof care plan.

Recommended Maintenance:

• Clean gutters in spring and fall to remove leaves, twigs, and debris

• Inspect downspouts for cracks, corrosion, or dislodgement

• Check fasteners and brackets to prevent sagging or detachment—especially after freezing or heavy rains

Water Infiltration: Detect and Repair Early

Leaks often start subtly but can cause major damage if left unchecked. They affect not only the roof structure but can also promote mold growth, compromise insulation, and damage ceilings.

They tend to appear around roof penetrations: chimneys, skylights, wall joints, ventilation systems, or poorly sealed solar panels. Pay special attention to these vulnerable areas.

Inspect the Following:

• Joints around flashing and openings

• Condition of sealants and caulking

• Cracks or bubbles in the roofing material

Preventive Measures:

• Replace cracked or dried-out sealants

• Seal leaks as soon as they appear

• Add protective elements like snow guards or vapor barriers under the roofing material

Act quickly when problems arise. Simple repairs—like resealing joints or replacing flashing—can prevent much costlier damage down the line. For more complex issues, book a professional roofer for a thorough diagnosis and lasting repairs.

Preventive Treatments and Long-Term Protection

Beyond cleaning and repairs, preventive treatments can significantly extend the life of your roof. These products, tailored to your roof type, enhance resistance to the elements. They act as an extra barrier against dirt, moss, and moisture buildup, and can preserve your roof’s appearance for years.

What Products Are Available for Maintenance of Metal Roofs?

Some options include:

• Anti-moss treatments to reduce vegetation growth

• Water-repellent coatings to protect against moisture

• Finishing products for metal roofs

Specific Guidelines for Different Roofing Materials

Each roof type has its own characteristics, which affect which products and methods to use. Choose treatments suited to your material to avoid damage and ensure effectiveness.

• Asphalt shingles: Use gentle, non-corrosive treatments that won’t affect the granules’ adhesion. Avoid abrasive or oil-based solutions.

• Clay/concrete tiles: Opt for mineralizing treatments that reduce porosity and moss growth. Products should be compatible with these materials.

• Metal roofing: Apply anti-corrosion coatings and special finishes to prevent rust and maintain aesthetics. Ensure compatibility with galvanized or pre-painted metal.

• Elastomeric membranes (flat roofs): Use UV-resistant sealants and coatings that handle freeze-thaw cycles and expansion. These help maintain waterproofing and prevent blisters or cracks.

These treatments should be applied in good weather, ideally by professionals. They reduce how often maintenance is needed, prevent water damage, and help your roof stay in great condition longer.

Maintenance for a Roof That Lasts

Roof maintenance requires diligence and foresight. Regular inspections, cleaning, gutter upkeep, leak prevention, and preventive treatments—together—help extend your roof’s lifespan. Regular checkups also let you better anticipate when a full roof replacement might be necessary.
