Buying a new roof is a significant investment, and understanding the warranty that comes with your asphalt shingles can feel like deciphering a secret code. It’s not just about the number of years; it’s about what those years actually cover and how it all works.
When you're looking at options, you'll often see terms like 'limited,' 'prorated,' and 'lifetime.' Let's break that down a bit, drawing from what companies like CertainTeed, a long-standing name in roofing since 1904, offer.
At its heart, an asphalt shingle warranty is a promise from the manufacturer that their product will perform as expected, free from manufacturing defects, for a specified period. The key here is 'manufacturing defects.' This generally means issues stemming from how the shingle was made, not from installation errors, extreme weather events (though some warranties address wind resistance separately), or general wear and tear.
The 'Lifetime' Nuance
That 'lifetime' warranty? It’s a bit of a special case. For individual homeowners, 'lifetime' typically means for as long as you own your home. It’s a comforting thought, right? However, for other types of ownership – think corporations, schools, or apartment buildings – this 'lifetime' often gets capped at a set number of years, like 50 or 40, depending on the specific product. It’s always worth checking the fine print to see who qualifies for the full 'lifetime' coverage.
Understanding Prorated vs. Non-Prorated
This is where things can get a little tricky, especially as your roof ages. A non-prorated warranty, often called 'SureStart™ Protection' by some manufacturers, is the gold standard for the early years. During this period, if a defect is found, the manufacturer will typically cover the full cost of repair or replacement, including labor, without deducting for the age of the shingles. It’s that extra layer of assurance when your roof is brand new.
After the SureStart period ends, most warranties become prorated. This means that if you have a claim, the manufacturer's payout will be reduced based on how old the shingles are. The older the roof, the less you'll receive from the warranty to cover repairs or replacements. It’s a way for them to acknowledge that shingles, like anything else, do age.
What's Typically Not Covered?
It’s just as important to know what’s not included. Most warranties won't cover the cost of removing the old shingles (tear-off), any associated metalwork or flashing, or disposal fees, unless you have a premium product with a full lifetime warranty that specifically includes these. Also, things like solar panels, satellite dishes, or garden roofs installed over your shingles are your responsibility to remove and reinstall if needed for a repair.
Making a Claim
If you do need to make a claim, be prepared to provide documentation. Manufacturers will often rely on industry standards like Bluebook® or RS Means® data to determine reasonable labor costs. Having your contractor's invoice or other proof of work completion is usually essential.
Ultimately, an asphalt shingle warranty is a valuable part of your roofing investment. Taking the time to understand its terms, especially the differences between prorated and non-prorated coverage and what constitutes a covered defect, can save you a lot of headaches down the road. It’s about peace of mind, knowing that the company stands behind its product, but also about being an informed homeowner.
