Frequently Asked Questions
Q: What factors affect roofing cost?
Roofing cost is affected by factors such as the size and pitch of the roof, the type of roofing material (e.g., asphalt shingles, metal, tile), labor costs, the complexity of the roof design, and the need for old roof removal.
How do you estimate roofing materials?
To estimate roofing materials, you typically measure the total square footage of the roof and then calculate how many “squares” (100 square feet) are needed, accounting for waste and specific material requirements like underlayment, flashing, and fasteners.
What is a square in roofing?
In roofing, a “square” is a unit of measurement equal to 100 square feet, commonly used to quantify the area of a roof and the amount of material required.
How long does a new roof last?
The lifespan of a new roof varies significantly by material; asphalt shingles typically last 15-30 years, metal roofs can last 40-70 years, and slate or tile roofs can last 50-100 years or more.
