What Is a Class 3 Shingle Wind Rating for Home Insurance?
It rates how well shingles resist impact, like hail, with Class 4 highest. Insurers may want Class 3 or better.

If the letter mentions roof condition, a Class 3 rating is one of the things an insurer checks, since it shows up on the shingle's product label or the roofing invoice from when it was installed. If your roof is aging or you don't know the rating, that's often the real issue behind the non-renewal, not the shingle class itself. Replacing worn shingles with Class 3 or Class 4 product, where hail and wind are common, can make the house easier to place with another insurer.
A non-renewal tied to roof condition doesn't mean no insurer will cover the house, it means this one wouldn't. Some weigh shingle class and roof age differently, and a roof that reads as a risk to one can look acceptable to another. Comparing options now shows what's available before the lender's deadline passes, and whether a Class 3 roof is worth enough to shop for.
How do I find out what class my roof already is?
Start with the paperwork from when the roof was installed. The roofing contractor's invoice or the warranty paper that came with it usually lists the shingle's brand and model, and from there, the manufacturer's spec sheet will say what class it carries. If a prior homeowner put the roof on, check with them or look for anything left in the house files. Some manufacturers also keep model specs searchable on their own sites if you know the brand.
If none of that turns up, a roofing contractor can often identify the shingle by look and tell you its class, or confirm there's a stamp or marking on the shingle itself that's visible from the attic side. This usually costs little or nothing if you're already having the roof inspected for other reasons, like an insurer's request.
Age matters alongside class. A shingle that was Class 3 or Class 4 when installed can lose that resistance over fifteen or twenty years as it weathers, so an old roof with a strong original rating isn't the same as a new one. If your non-renewal letter mentions roof age specifically, the rating on record may be less relevant to the insurer than how many years the shingles have been on the house.
None of this is required before you look at other coverage. An inspection or a contractor's note on the shingle class can help if an insurer asks, but you don't need to track it down just to start comparing what's available before the deadline in the letter.
Does a Class 3 roof cost more to install than a regular one?
Class 3 and Class 4 shingles are built with tougher materials, sometimes a different asphalt mix, a reinforced mat, or impact-modified coatings, and that shows up in the price. Expect to pay more per square than standard three-tab or basic architectural shingles, though the gap varies by brand and region. A roofing contractor quoting the job can tell you the difference for your specific roof size and shingle choice.
Some of that extra cost may come back. A number of insurers offer a discount for impact-resistant roofing, particularly in areas where hail is common. In places where hailstorms are frequent enough to affect pricing broadly, the discount can be worth asking about when comparing quotes. Whether it offsets the installation cost depends on the size of the discount and how long you plan to stay in the house.
If the roof needs replacing anyway, because of the non-renewal or because it's at the end of its life, upgrading to Class 3 or Class 4 at that point adds less to the total job than doing it as a standalone project later. Replacing a functional roof early just to chase a better class rating is a bigger decision. It's worth weighing against what the insurer actually requires versus what would merely help.
Not every insurer requires Class 3 or better, and not every house needs it to get covered. Some weigh other factors, like overall roof age or condition, more heavily than shingle class alone. Before deciding to reroof, it's worth finding out whether the shingle class is the actual sticking point for coverage or just one factor among several, since that changes whether the upgrade is necessary or optional.
Before you compare
Check your roof's age and, if you can find it, the shingle's class from the installation paperwork. Having both ready makes it quicker to see which insurers will still cover the house before your deadline.
