CENTURY ROOFING & SIDING IN OTTAWA
Frequently Asked Questions
Most residential roof installations in Ottawa are completed in 1–2 days, depending on roof size, pitch, skylights, ventilation upgrades, and weather.
In most cases, yes. Removing old shingles helps confirm the roof deck condition and supports a proper underlayment and flashing installation.
Ventilation is reviewed during quoting. Proper intake and exhaust ventilation helps reduce ice dams, moisture, and premature shingle wear in Ottawa winters.
Warranties vary by shingle type and system. Most homeowners receive manufacturer coverage plus workmanship coverage, and details are confirmed in writing.
Crews monitor forecasts and protect exposed areas with underlayment and tarps. If conditions become unsafe, the roof is secured and work resumes when safe.
Call a professional Ottawa roofer for inspection. Leaks often come from flashing, vents, valleys, skylights, or missing shingles rather than the shingles alone.
Active leaks, storm damage, missing shingles exposing underlayment, or sagging areas can cause fast interior damage. These are typically treated as emergency repairs.
Often yes, depending on temperature and safe access. If a permanent repair is not possible immediately, a temporary seal or tarp can reduce further damage.
Common causes include failed flashing, improper vent sealing, ice dams, damaged underlayment, or poor attic ventilation. A full inspection identifies the root cause.
Leak detection typically includes examining shingles, flashing, vents, valleys, attic moisture, and water path patterns. The visible ceiling stain is not always the entry point.
If your roof is near end-of-life, leaks keep returning, or shingles are failing across large areas, roof replacement can be the more cost-effective long-term solution.
Pricing depends on roof size, pitch, layers to remove, decking repairs, ventilation, flashing complexity, skylights, material type, and access around the home.
Many Ottawa roof replacements are completed in 1–2 days. Larger or more complex roofs can take longer depending on weather and repair requirements.
Yes. A written estimate should outline materials, ventilation, underlayment, flashing work, cleanup, timeline, and warranty information for your Ottawa roof replacement.
Spring through fall is popular, but many projects can be completed whenever conditions are safe. Scheduling depends on weather, product availability, and urgency.
A common recommendation is once per year and after major storms. Routine roof maintenance helps prevent leaks and extends shingle life.
Yes. Overflow and backups can contribute to fascia damage, ice dams, and water intrusion. Keeping gutters clear supports roof and foundation protection.
Ice dam prevention usually involves proper attic insulation, ventilation, air sealing, and ensuring gutters and downspouts drain correctly.
Growth can retain moisture and accelerate wear. Safe cleaning methods and preventative measures can help protect your roofing system over time.
Inspections typically check shingles, flashing, vents, valleys, skylights, attic moisture, and ventilation performance, plus signs of wind or ice damage.
Fibreglass shingles use a fibreglass mat base with asphalt and granules. They are a common choice for Ottawa homes due to durability and value.
Lifespan depends on product quality, ventilation, installation, and maintenance. Many homeowners see 20–30 years with proper roof care.
Many fibreglass shingle systems offer strong wind ratings when installed correctly with the right nails, starter strip, and sealing pattern.
Most fibreglass asphalt shingles are designed with fire resistance in mind. Always confirm product specs and system components during quoting.
Fibreglass shingles are typically one of the most cost-effective roofing materials. Total price still depends on roof size, complexity, and upgrades like ventilation.
Residential siding services typically include removal, installation, trim, weather barrier, and repairs. Options depend on your home style, budget, and performance goals.
Yes. Proper siding installation with house wrap and insulation can reduce drafts and help improve overall energy efficiency in Ottawa’s climate.
It can. Water intrusion behind siding may lead to rot, mold, or moisture problems that impact the roofline, fascia, soffits, and overall building envelope.
Yes. High winds can loosen panels and trim. Quick repairs help prevent water intrusion and reduce the risk of larger exterior damage.
A siding quote typically includes measurement, material choice, trim details, removal needs, and any repairs to underlying surfaces. Booking an onsite inspection is the fastest route.
Eavestroughs (gutters) direct water away from the roof edge and foundation. Proper drainage helps reduce fascia damage, leaks, and water pooling around the home.
Many Ottawa homeowners clean gutters in spring and fall, and after heavy storms. Homes with trees may need more frequent cleaning.
Yes. Poor drainage can worsen ice buildup at the eaves. Maintenance, ventilation, and proper insulation all work together to reduce ice dam risk.
Signs include persistent leaks, sagging, rust, separated seams, overflow, or water pooling near the foundation. Replacement can restore proper drainage and protection.
Yes. Downspout placement and extensions help move water away from the foundation. Correct pitch and secure fasteners reduce overflow and water damage.
A gutter protection system helps reduce debris buildup so water can flow more consistently through gutters and downspouts, especially during Ottawa’s fall leaf season.
Many homeowners find them helpful if trees cause frequent clogs. They can reduce overflow, maintenance, and water backup that may contribute to ice-related issues.
They reduce buildup significantly, but occasional checks are still recommended to ensure water flow remains clear and fasteners remain secure.
They can help support better drainage, but ice dams are usually driven by attic heat loss and refreezing at the eaves. Ventilation and insulation remain key.
Installation depends on the product and roof edge design. Systems are fitted to reduce debris entry while keeping water flow effective into the gutter channel.
Yes. Light commercial roofing often includes repairs, replacements, and maintenance planning. Recommendations depend on roof type, drainage, and building use.
Commercial estimates typically start with a roof inspection to assess membrane condition, flashing, penetrations, drainage performance, and any active leaks.
Many building owners schedule inspections twice per year and after major storms. Preventative inspections can reduce downtime and emergency repair costs.
Common issues include failed flashing at penetrations, seams, ponding water, clogged drains, and damage from foot traffic. Inspections identify the cause and scope.
Yes. Maintenance plans can include scheduled inspections, minor repairs, drainage checks, and documentation to help extend roof lifespan and reduce surprise failures.
