Roofers build and repair flat roofs - using hot asphalt, gravel and waterproof sheet materials. They may also build and repair sloped roofs - using asphalt and wood shingles, shakes and masonry or baked clay roofing tiles and metal materials - although this type of work is typically done by a Residential Steep Roofer. Their work also involves setting up scaffolding to provide safe access to roofs. Roofer is a nationally designated trade under the Inter-provincial Red Seal program. Many Roofers work in the construction industry or for home renovation firms. They may need to estimate the materials needed and the cost of installation, in some cases from plans or project specifications. They may determine what costs and materials can be saved and what structures need to be replaced. Roofers work in high and potentially dangerous places, making safety considerations vital. Roofing work is physically demanding, and attrition due to age and diminishing stamina is higher than in other trades. Opportunities for Roofers are closely tied with levels of construction and renovation activity, and weather can have a significant bearing on work scheduling.
