How Roofers Charge Per Square – What You Need to Know

If you’ve ever asked a roofer for a quote, you’ve probably heard the term “per square.” It simply means the cost for a 100‑square‑foot section of roof. Knowing how that price is built helps you compare quotes and avoid surprises.

What Makes Up the Price Per Square?

Roofers look at three main things when they set a square price: materials, labor, and extras. Materials cover the shingles, underlayment, flashing, and any waterproofing. Labor is the crew’s time for removal, installation, and clean‑up. Extras include things like roof ventilation, roof decking repair, or a steep‑slope surcharge.

For example, a basic asphalt shingle roof might be $80‑$120 per square for materials alone. Add labor at $40‑$70 per square, and you’re around $120‑$190 total. If you need a metal roof, the material cost jumps to $150‑$250 per square, pushing the final price higher.

Factors That Can Change the Per‑Square Rate

Location matters. Roofers in London or the South East often charge more because of higher living costs. Roof pitch also matters – a steep roof is harder to work on, so many companies add a 10‑25% surcharge.

Older homes can bring hidden costs. If the roof deck is rotted or the existing shingles are stuck to the decking, removal takes extra time and may need replacement material, bumping the per‑square rate.

Seasonal demand influences pricing too. In summer, when most homeowners schedule work, rates can be 5‑10% higher. Winter projects might be cheaper but could face weather delays.

Finally, the size of the job can affect the unit price. Large commercial roofs often get a lower per‑square cost because the crew can work more efficiently. Small residential jobs might see a higher rate because the crew still needs to travel and set up.

When you ask for a quote, ask the roofer to break down the per‑square cost into material, labor, and any add‑ons. This transparency lets you see where you can save – perhaps by choosing a different shingle style or fixing deck issues yourself.

Remember that the cheapest per‑square price isn’t always the best deal. A low quote might use low‑grade materials that need replacement sooner, costing you more in the long run.

To get a fair price, get at least three estimates, compare the detailed breakdowns, and check reviews for each contractor. A reputable roofer will be happy to explain each line item.

In short, the per‑square rate is a handy way to understand roof pricing. Look at materials, labor, and extras, factor in location, pitch, and roof condition, and you’ll be equipped to choose the right roofer without overpaying.
