A shingle wind warranty is a manufacturer's written statement about how well its shingles should hold up in wind, usually tied to a wind speed rating and a set of installation requirements. The rating describes how the product was tested, and the warranty describes what the manufacturer will do if the shingles fail under the stated conditions. Both depend on the roof being installed the way the manufacturer's instructions say.
What does a wind rating actually mean?
A wind rating is a number a manufacturer attaches to a shingle, based on laboratory testing to a recognized standard. It is a measure of how the product performed in a controlled test, not a promise about what any storm will do. Real wind is gusty, comes from different directions, and carries debris. We do not quote any figures here, because the numbers differ by product line and change over time. Look them up in the product's published documents.
Many manufacturers also describe the number of fasteners and the type of installation needed to meet the rating. Those details matter as much as the number.
How is a wind warranty different from a wind rating?
| Wind rating | Wind warranty | |
|---|---|---|
| What it is | A tested performance level for the product | A written promise about what the manufacturer will do if the product fails |
| Where it lives | Product data sheets, wrappers and test standards | The warranty document |
| What it depends on | The test conditions | Installation, product use, time limits and exclusions |
| Who it protects | Informs your choice | You, as the owner, if the terms are met |
The warranty usually has fine print about the length of coverage, what is repaired or replaced, who pays for labor, and what voids it.
How does installation affect the warranty?
This is the part many homeowners miss. Manufacturers' wind coverage is generally tied to following their installation instructions. Common requirements include:
- A specific number and placement of nails per shingle
- Correct nail depth, with no overdriven or underdriven fasteners
- Starter strips at eaves and rakes, which help the edges resist wind
- The right underlayment and sealing conditions
- Installing within the temperature range the manufacturer sets, since shingle sealant strips need warmth to bond
Our crews' view is that installation matters at least as much as the product, and that is why we follow each manufacturer's instructions for the shingle on the roof. Our owner, Jeremy Hays, likes to talk about shingle lines he trusts, but he is clear that you should compare the products on their published documents and not on opinion alone. For a feel for how product tiers differ, see our comparison of Class 3 and Class 4 shingles.
What can limit or void a wind warranty?
Terms differ by manufacturer, so read yours. Common examples that warranties describe:
- Installation that did not follow the manufacturer's instructions
- Damage from foreign objects, fallen trees or debris, which is typically treated as a different kind of loss
- Roofs altered after installation by a third party
- Lack of proper ventilation
- Wind speeds above the warranty's stated limit, if there is one
- Missed time limits for reporting a problem
Start with the actual documents. Our guide on how to read a shingle warranty walks through the document in more detail.
What should I ask my roofer?
- Which wind rating applies to the shingle you plan to install, and where can I read it?
- What installation requirements does the manufacturer set to maintain the wind warranty?
- Will you follow those requirements on my roof, including fasteners and starter strips?
- Who registers the warranty, and what do I receive?
- What is the process if shingles blow off?
- Is the workmanship covered separately by you, and for how long?
Remember that a manufacturer's warranty and a roofer's workmanship warranty are two different documents.
Frequently asked questions
Is a wind warranty the same as an insurance policy? No. A warranty is the manufacturer's promise about its product. Insurance is a separate contract with your insurer. Wind damage under a policy depends on the policy language, so read yours and ask your agent.
Does a higher wind rating mean I can skip good installation? No. The rating assumes correct installation. A better shingle on a poor install can still fail.
Does a wind warranty cover hail? Generally those are separate topics. Hail resistance is typically described by an impact rating and covered in different documents. Our page on hail damage repair covers repair questions.
Does the warranty transfer if I sell the house? Some do and some do not, and some require registration or fees. Check the specific terms.
Can I see the warranty before I sign? You should. Ask your roofer for the document or its link before you decide.
Why do shingles blow off in the first place? Common reasons include low-temperature installation that stops the strips from sealing, too few or badly placed nails, and old, worn or damaged shingles. A roofer can look at which applies.
