Signs It’s Time for a Roof Replacement
Not sure if you need a full roof replacement? An old roof often gives clear warning signs that it’s nearing the end of its service life. Catching these signs early can save you from the stress and expense of interior water damage.
- Curling, Cracking, or Missing Shingles: Shingles that are curling at the edges, cracked, or have blown off in sections leave your roof vulnerable to leaks.
- Bald Spots & Granule Loss: If you see dark “bald” spots on your roof or notice an excessive amount of shingle granules in your gutters, it means the protective top layer of your shingles has worn away.
- A Roof Over 20 Years Old: Most asphalt shingle roofs have a lifespan of 20-25 years. If your roof is approaching or has passed this age, it’s time to start planning for a replacement, even if there are no visible leaks.
- Dark Streaks or Moss Growth: While dark streaks are often just algae, they can detract from your home’s appearance. Moss growth is more serious, as it can trap moisture against the shingles and lead to deterioration.
- Water Stains in the Attic: The clearest sign of a problem is evidence of a leak. Check your attic regularly, especially after heavy rain, for water stains on the underside of the roof deck or on your insulation.
Our Thorough Roof Installation Process
We know a roof replacement is a major project, and we want you to feel confident and informed. To ensure every detail is handled correctly and you know exactly what to expect, our crew follows a meticulous, step-by-step process:
Step 1: Tear-Off and Deck Inspection
Our process begins with the complete and careful removal of all old shingles and underlayment. This allows us to perform a thorough inspection of the underlying wood decking, replacing any rotted or damaged sections to create a solid foundation.
Step 2: Preparing the Deck for Installation
We install a protective ice and water shield in your roof’s most vulnerable areas, like valleys and eaves. Then, we lay down a new layer of high-performance synthetic underlayment across the entire roof deck for a secondary layer of water resistance.
Step 3: Expert Shingle Installation
We begin by installing starter strips and then meticulously lay each course of your new CertainTeed shingles. Our crew follows the manufacturer’s precise specifications for alignment and nailing patterns to ensure maximum durability and wind resistance.
Step 4: Flashing, Ventilation & Finishing
We install new flashing around chimneys, skylights, and vents to create a watertight seal. We also install ridge vents to ensure proper attic ventilation and finish the roof with matching ridge cap shingles for a clean, cohesive look.
Step 5: Meticulous Site Cleanup
We treat your property with respect. Throughout the project, we protect your landscaping and siding. After the job is done, we perform a final, thorough cleanup, including using magnetic rollers to collect any stray nails from your lawn and driveway.

“I interviewed five different roofing companies and Prairie State Siding & Window’s workmanship warranty and shingle warranty surpassed every other company’s. Prairie State Siding & Window is a one stop shop… I had my roof, soffits, vinyl siding, gutters and chimney caps replaced. After meeting with Josh, for the first time, he was the only one that followed up with me and asked me for my business. Throughout the process, Josh called me on a daily basis to give me updates and to explain the next steps. Josh’s crew was respectful of my yard, took the time to cover my pool from debris and was very polite. Everything went perfectly from beginning to end and I couldn’t be happier. I highly recommend Prairie State Siding & Window to anyone needing a roof, siding, gutters, soffits or windows. I’m fact, I’ve already referred two friends to them.”
