Replacing a roof can be one of the most significant expenses for a homeowner. That’s why a roof warranty matters. But many people don’t know what these warranties really cover or how they work. Before you agree to a new roof, take time to understand the basics. Here’s what you need to know about roof warranties and how to make sure you’re covered if something goes wrong.
Why roof warranties matter
A roof warranty protects you if problems show up later. It can save you from paying for repairs out of pocket if the issue is because of poor materials or installation mistakes. Good Naperville roofing companies always explain warranty terms before starting any work.
Two types of roof warranties
Most warranties fall into two parts: manufacturer and workmanship.
Manufacturer warranty: This covers the roofing materials. For example, if your shingles crack too soon or the sealant fails, the manufacturer may pay to replace those materials. But this usually does not cover the labor to fix the problem.
Workmanship warranty: This comes from the contractor. It covers mistakes made during the installation. If your roof leaks because the flashing was put in incorrectly, this warranty should pay for labor and materials to fix it.
A trusted Naperville IL roofing company will give you clear paperwork that explains both parts.
What does “lifetime” really mean?
Some companies advertise “lifetime” warranties. But read the fine print. Many “lifetime” warranties only cover full costs for a set number of years. After that, they may pay less as time goes on. For example, a shingle warranty might cover 100% for the first ten years, then drop each year after.
Always ask the contractor how long each part stays in effect.
Common things that void a warranty
This is where many homeowners are surprised. Some things can cancel your warranty without you even knowing it.
- Poor attic ventilation: If your attic traps heat and moisture, shingles can wear out faster. Some manufacturers void warranties if they find insufficient ventilation.
- Layers over old roofing: Adding new shingles over old ones can save money now, but may void a warranty. Most Naperville roofing companies recommend tearing off the old roof first.
- Unauthorized repairs: Fixing a roof yourself or hiring someone not approved by the manufacturer can cancel your coverage.
- Not registering: Some manufacturers require homeowners to register the warranty within a certain time. Missing this step could mean you’re not covered.
Always ask your Naperville, IL, roofing company to walk you through the steps to keep your warranty valid.
What to check in the paperwork
Before you sign, read your warranty papers. Look for:
- Length of coverage for materials and workmanship
- What’s included and what’s not
- What maintenance you must do
- How you make a claim if needed
- Who covers the cost of labor, materials, or disposal
If you don’t understand something, ask your contractor. Trusted Naperville roofing companies will take the time to explain.
Why local matters
Roofing needs vary by climate. What works in the Southwest might not work here. Local Naperville roofing companies know what weather conditions can do to shingles, flashing, and underlayment. They also understand local code rules and inspection steps that tie into warranties.
Some national contractors push the same warranty everywhere, but it’s smarter to talk with a Naperville roofing company that has years of experience in this area. They can explain how local conditions affect your roof’s lifespan and warranty options.
Keep your warranty valid
Getting the warranty is step one. Keeping it active takes a little effort:
- Get regular roof inspections to catch problems early.
- Fix small issues right away so they don’t grow.
- Keep records of any work you do or hire out.
- Check your attic ventilation every few years.
Final thoughts
A new roof is a big deal. A solid warranty helps protect that investment. Don’t just take someone’s word for it; read the warranty and ask questions. A trusted Naperville, IL, roofing company will be happy to break down what’s covered, how long it lasts, and how to avoid mistakes that cancel your coverage.
With the correct information, you can feel good knowing your roof is built to last, and you’re covered if something goes wrong.
