Rethink Your Roof: When to Replace, What to Use, and Why CertainTeed Is a Smart Choice

Summer is prime time for roof repairs and full replacements — especially after heavy spring rains and high winds. Whether you’re patching problem areas or starting from scratch, understanding your options can help you make a long-term investment in your home. At Jonesville Lumber, we stock high-performance CertainTeed shingles designed to last — and we’re here to help you make the right choice.

1) Signs It’s Time to Replace Your Roof

Your roof might be ready for replacement if you’re seeing curled or cracked shingles, granules washing into your gutters, water stains inside the home, or soft, sagging spots. If your roof is 15 to 20 years old (or older), it’s a good idea to have it evaluated — especially with the temperature swings and tree coverage we see in southern Michigan.

2) What to Look for in Replacement Shingles

Not all shingles are created equal. Homeowners should look for shingles that hold up to harsh weather, include a strong warranty, and offer resistance to algae and discoloration. Aesthetic options matter, too — especially if you're upgrading your curb appeal or preparing to sell.

3) Why We Recommend CertainTeed Landmark

CertainTeed’s Landmark line is a customer favorite for a reason. Landmark 30 offers solid protection and great value, while Landmark PRO takes it up a notch with a heavier construction and extended warranty coverage. We recently received a new Landmark PRO color — a bold, deep green — that’s perfect for homeowners looking to stand out in the best way.

When you buy CertainTeed at Jonesville Lumber, you’ll have all of the supplies you need to complete your roofing project.

4) We Deliver material — Wrapping Up

Need material delivered to the roof? Our fleet of trucks can get it there safely and efficiently — just ask when you place your order.

Whether you're a contractor tackling multiple jobs or a homeowner planning a big update, the right shingle makes all the difference. Stop by Jonesville Lumber to check out our CertainTeed selection, compare colors, and get expert advice on what your home needs.
