How to Reduce Waste and Save Money on Every Roofing Job

Smarter Planning, Better Margins, and Less Cleanup

In the roofing business, profit margins can be razor-thin—and one of the biggest threats to those margins is material waste. Whether it's excess shingles, damaged product, or avoidable labor costs, waste adds up fast. The good news? With the right strategies, contractors can significantly reduce waste and save money on every roofing job. At CGR Wholesale, we work closely with pros like you to help improve efficiency from order to installation. Here's how you can tighten up your process and maximize your bottom line.

1. Start With Accurate Measurements

The first step in cutting down waste is getting your numbers right. Use precise roof measurements and convert them to roofing squares, accounting for complexity, pitch, and overhangs. Whether you're using traditional tools or satellite imagery from services like EagleView, accuracy up front helps avoid over-ordering.

Pro Tip: Always factor in the proper waste percentage—typically 10-15%—but don’t go overboard unless the roof design truly calls for it (like in cut-up or steep-slope projects).

2. Order Only What You Need (With a Little Buffer)

It might seem safer to over-order "just in case," but that approach leads to leftover bundles that can’t always be returned. Instead, calculate your needs carefully and keep a small buffer for damaged pieces or errors.

At CGR Wholesale, we can assist with material planning to ensure you get just the right amount, helping to reduce overages and unnecessary costs.

3. Use Quality Materials That Hold Up

Cheaper products might seem like a cost-saver upfront, but they can lead to breakage, waste during installation, or callbacks down the road. High-quality shingles, underlayments, and fasteners install more cleanly and perform better.

When you choose premium brands like Owens Corning, TAMKO, and CertainTeed—available through CGR Wholesale—you’re investing in consistency, durability, and long-term savings.

4. Train Crews on Efficient Installation

A skilled crew doesn’t just work faster—they waste less. Common causes of waste include:

• Misaligned shingle courses that need to be redone

• Poor cutting techniques

• Damaged materials from careless handling

• Excessive starter or ridge cap waste

Regular training and clear communication go a long way toward improving installation efficiency and reducing throwaway material.

5. Plan Deliveries Strategically

Lost or damaged materials due to poor storage or weather exposure are a hidden cost many contractors overlook. Avoid this by timing your deliveries with the start of the project and storing materials properly onsite.

CGR Wholesale offers timely, jobsite-direct delivery, helping you minimize storage issues and keep your crew focused on installation—not logistics.

6. Reuse and Recycle When Possible

Some materials, like underlayment scraps or partial bundles, can be reused on other projects. Consider keeping a running inventory of leftover materials for use on repairs, small jobs, or training. You can also recycle old shingles and metal scraps where facilities are available.

Bonus: Promoting recycling efforts can be a marketing advantage for environmentally conscious clients.

7. Keep an Eye on the Forecast

Nothing ruins roofing materials faster than unexpected rain. Always check the weather and avoid scheduling tear-offs if rain is likely. Wet materials often can’t be used and become waste before the job even starts.

8. Partner with a Supplier Who’s Got Your Back

Working with a knowledgeable, dependable roofing supplier is one of the best ways to reduce waste. At CGR Wholesale, we help contractors stay organized, on budget, and ready for anything.
