What to know before you buy
Roof area is larger than the footprint
A sloped roof has more surface area than the floor plan beneath it. The steeper the pitch, the more material is needed to cover the same footprint.
Do not walk a roof you are unsure about
Roof work involves height, steep slopes, and weather exposure. Unless you have the right equipment and experience, hire a licensed roofing professional.
Confirm the scope with a professional
Underlayment, flashing, ventilation, and the number of existing layers all affect the job. A roofer can confirm these during an inspection before you order materials.
