How to Estimate a Roofing Job

When estimating a roofing job, you’ll need to know how long the job will take, how many laborers you’ll need and what their hourly rates are, and the types and quantities of materials and equipment required. In order to accurately estimate the scope of work, you’ll need to consider the size and pitch of the roof. Roof size can determine which types of equipment must be used — for example, if you need to remove a large amount of material from the job site, you’ll need a dumpster or dump truck, whereas if you’re fixing a roof and leaving it intact you won’t need to consider this cost. You’ll also need to discuss with the prospective customer which types of material they want. Do they want to use new materials or stick to what’s already on their roof?

Measuring the Size of the Roof

The length and width of the roof can be measured with a measuring tape. As the measurement should also consider the length of features, including eaves, valleys, hips, and ridges, as well as chimneys and ventilation pipes, sometimes it helps to break the roof into segments and measure those individually. Multiplying length by width produces the roof’s area.

Calculating the Pitch of a Roof

Pitch is another word for steepness. You can use a level to measure the distance between the level and the roof’s surface. In order to get an accurate figure for the total area of the roof, you can use a pitch multiplier table. You can find these by doing a quick search on Google. Here are some tables to get you started:

You’ll multiply the roof’s area (length x width) by the pitch multiplier to determine the total surface area of the roof.

Estimating Roofing Materials

Roofing materials often come in squares; a square comprises enough shingles to cover 100 square feet. You can divide the square footage by 100 in order to figure out how many squares you’ll need.

Common Roofing Materials

Common roofing materials include:

Fiberglass, composite, and asphalt shingles
Metal roofing
Wood shake
Clay tiles

You may also need to consider whether a job will require:

Shingles
Vents
Nails (4-5 per shingle)
Underlayment and ice and water shield for the roof’s vulnerable areas
Protective tarps
