HOME ROOFING SERVICES
GAF Master Elite Contractor Ensuring Quality and Longevity for Your Roof
Your roof is more than just a ‘hat for your home’; it’s a vital component that protects your home and enhances its curb appeal. At John McLellan Contracting, we understand the importance of protecting your largest household investment and specialize in high-performance roofing systems that are long-lasting and can be trusted to stand up to the elements. With three decades of experience, John has built his business on integrity, providing homeowners with reliable and professional roofing services for repairs and replacements.
Whether you want to have a new roof installed or an existing one maintained, John McLellan Contracting has got you covered. As a trusted residential roofing company, we cater to individuals, condo corporations, and businesses in the Durham region who appreciate high-quality, long-lasting workmanship. We are licensed and registered with the WSIB and carry a $5 million liability insurance. Our expertise enables us to create custom roofing solutions backed by lifetime warranties.
As a certified GAF Master Elite Contractor, we offer 50-year limited lifetime warranties. Want to increase the lifespan of your roofing system? Our team specializes in the complete GAF Lifetime Roofing System. We install Timberline HDZ or Timberline Ultra shingles, paired with the rest of the GAF roofing system: GAF WeatherBlocker starter strips to protect and solidify your roof in the most vulnerable wind spots at the rakes and eaves. This works together with WeatherWatch & StormGuard leak barriers, Shingle-Mate, and Deck-Armor to make your roof watertight before the shingles are even installed. With our professional residential roofing service, quality shingles, leak barriers, and roof deck protection add layers of protection against the elements and help prevent roofing problems that can affect performance and lifespan.
ROOF INSTALLATION
An improperly installed roof is unreliable, can cause you problems, and may need costly repairs frequently. This is in addition to possibly voiding the manufacturer’s warranties.
Installing a roof is a specialized task, best left to a professional you can trust. Our factory-certified roofing experts are trained and equipped to manage the complexities of roof installation. As part of our home roofing services, we carefully study the factors that can affect the installation process and develop a plan to manage them. An effective installation plan prevents confusion and roofing mistakes that can lead to frustrating project delays and cost overruns.
ROOF REPAIR
Over time, roofs can develop problems. If left unaddressed, roofing problems can affect your roof’s structural integrity and lead to damage.
Whether you have a leaky roof or your roof is missing shingles, we can help. Our professional roofing services focus on the root causes of roofing problems instead of their symptoms. Their experience and know-how enable them to come up with innovative solutions to complicated roofing problems.
ROOF MAINTENANCE
On request, we can perform inspection, service, and preventive maintenance on roofs. As part of our home roofing services, we reapply caulking and sealants during maintenance sessions and repair or replace damaged parts to address current problems while preventing future issues. Regular maintenance keeps your roof in tip-top shape, improves its performance, and maximizes its life expectancy.
