Because the housing stock varies so widely, no single price per square foot describes the whole municipality honestly. Anyone quoting a roof replacement in Markham sight unseen, over the phone, without measuring, is guessing. A proper quote follows an on-site inspection that includes the attic wherever access allows. Contractors typically price in “squares,” where one square equals 100 square feet of roof surface. It is made with a combination of asphalt and rubber modifiers that enhance its fire-resistant properties. This type of roofing material meets the fire safety standards set by building codes and can provide an added layer of protection against fire hazards.

Roof joists can weaken over time due to prolonged moisture exposure, unnoticed leaks, poor ventilation, or pest activity. When water penetrates the roof system and reaches the attic structure, wood can begin to rot, reducing its load-bearing strength. Repairing roof joists starts with identifying and fixing the source of moisture. Damaged joists may be reinforced using a method called “sistering,” where new lumber is installed alongside the existing joist for added strength. Because joists are structural components, repairs should always be performed by experienced professionals to ensure safety, stability, and compliance with building codes. We are excited to bring our expert services to the vibrant city of Markham, with dedicated coverage for key neighbourhoods including Unionville, Thornhill, and Cornell.
Silicone coatings are typically applied to a roof using a spray or roller method. First, the roof surface is cleaned and prepared to ensure proper adhesion. Then, the silicone coating is evenly applied in multiple layers, allowing sufficient drying time between each coat for optimal performance and durability.
All flashings are properly secured and sealed to withstand Markham's strongest wind conditions throughout all seasons. Markham faces strong winds, particularly during seasonal storms and winter weather systems moving through the Greater Toronto Area. Gusts can exceed 70 km/h, potentially compromising standard shingle installations. Markham experiences average annual snowfall of 100cm, creating significant ice dam risks. Fluctuating temperatures between freezing and thawing create perfect conditions for ice accumulation along roof edges, particularly in older neighborhoods with mature tree coverage.
