A new roof can lower your homeowners insurance premium, but not always and not by a set amount. Insurers price roofs by age, material, shape and, in some states, by documented features that resist wind and hail. Whether any of that reaches your premium depends on the carrier, on your state and on what the carrier has on file about your building.
That last point is the one owners miss. Rating data is entered once, usually from an application, and then carried forward year after year. If your roof was replaced and nobody told the insurer, you are still being rated on the old one.
What insurers look at
| Factor | Why it matters |
|---|---|
| Roof age | Newer coverings are less likely to fail in a storm, and less likely to trigger a condition review |
| Material | Fire and hail performance differ by material, and some are difficult to insure at all |
| Impact rating | Several carriers credit a documented impact classification on the covering |
| Roof shape | Hip roofs generally handle wind better than gable roofs |
| Wind features | In some states, documented mitigation features attract set credits |
| Condition | Curling, missing units, open flashings and prior repairs can cost more than age does |
Age and condition are not the same thing, and insurers increasingly treat them separately. A well maintained older roof with records behind it presents differently from an untouched one of the same age.
Where a discount actually comes from
A premium falls for one of three reasons. The carrier applies a rating factor for the age or class of the covering. The state or the carrier gives a defined credit for documented mitigation features. Or the roof moves you out of a surcharge or a restricted settlement basis you were already paying for.
Only the second of those is usually published. The first two are inside the rating plan, which is why the only reliable way to find out what your roof is worth is to have the same policy quoted both ways.
After you replace your roof
- Tell your insurer or agent in writing, with the completion date
- Send the material, the manufacturer product data and any impact or wind rating
- Send the invoice, the permit and any inspection record
- Ask whether a mitigation inspection is recognized in your state and would pay for itself
- Check the next declarations page to confirm the change was actually applied
Also ask what the new roof does to the terms, not just the price. Replacing an older covering can move you off a roof payment schedule or an actual cash value settlement and back onto replacement cost, which is often worth more than the premium saving.
Before you choose a roof
If insurance cost matters, ask your agent which materials, classes and ratings your carrier credits before you sign a contract. Get the answer against your own policy, because credits are carrier specific and a neighbour’s experience tells you nothing about yours.
Ask your roofer for the product data sheet up front, and check that the product named on the contract is the one the rating belongs to. Substitutions during a busy storm season are common and they quietly remove the discount.
What pushes a roof premium up
- An older covering, or one the carrier will no longer write at replacement cost
- Visible condition problems an inspector or an aerial image picks up
- A claim history on the property, including claims made by a previous owner
- A location with a hail or windstorm record the carrier has repriced
- Materials a carrier treats as harder to insure, such as wood shakes in a fire exposed area
Several of these are outside your control. Condition is not, and it is the one carriers check most often. Aerial imagery and third party property data now feed underwriting directly, so a roof with moss, missing units or a patched slope can prompt a condition review without anyone visiting the property.
Weigh price against payout
A lower premium is only part of the picture. Read how roof age changes the terms an insurer will offer, and how the policy terms you agree to decide what a claim actually pays. Buying a cheaper policy that settles the roof at actual cash value can cost far more in one storm than it saves over a decade.
This guide is general information, not legal, financial or insurance advice. Your policy, your carrier and your state’s rules decide your situation.
Common questions
Does a metal roof lower your home insurance premium?
Sometimes. Metal is not a discount in itself, but it scores well on what insurers rate: fire resistance, wind uplift performance and a long service life.
- Whether that reaches your premium depends on the carrier, product, fixing and state
- Carriers tie roof credits to a documented rating, not to the word metal
- So the manufacturer paperwork matters more than the material
- Metal can dent in hail without leaking, and a cosmetic exclusion may not pay dents
- Some carriers rate metal no better than a good asphalt roof
Ask your agent to quote the same policy against the roof you have and the roof you are considering, before you sign anything. Compare the premium saving against the replacement cost and the settlement terms, because a cheaper policy that pays less on a claim is not the better deal.
Does filing a hail claim raise your insurance rates?
It can. Carriers record every claim you report, including ones they decline to pay, and that history is visible to other insurers when you shop.
- The effect depends on the carrier, how the claim is coded and your state rules
- Weather claims are often treated differently from claims where the owner was at fault
- After a regional storm an insurer may view one house differently from a whole area
- That is company practice, not principle, so ask your agent before you file
- If the damage is near your deductible, a claim may pay little and still show
Leaving real damage unreported is worse, because unrepaired storm damage becomes the wear and neglect that gets the next claim denied. Document the damage either way with a dated inspection report, then decide with the numbers in front of you.
Is a hip roof cheaper to insure than a gable roof?
Often, yes, in wind exposed states. A hip roof slopes on all sides, giving wind fewer flat vertical surfaces to push against, and it tends to perform better in high wind.
- Several carriers and state wind mitigation programs recognize that in their rating
- The credit is never automatic and usually needs the shape documented on a form
- That form records the geometry, deck attachment, covering and wall connections
- A roof mostly hip but with dormers or a large gable end may not qualify
- These forms usually measure how much of the perimeter is hip
Do not rebuild a roof shape to chase a premium, because shape is fixed by the structure and changing it is a major job. What is worth doing is checking that your carrier has the correct shape on file, since rating data is often carried over from an old application.
What is a wind mitigation inspection and is it worth getting?
It is a standardized inspection that records the wind resisting features of a building, and in several wind exposed states carriers are required or willing to credit what it documents.
- Typically the roof covering and its approval, the deck attachment and roof shape
- Also the roof to wall connections, secondary water barrier and opening protection
- The fee is paid once and the credits, where they apply, repeat every year
- An inspector can tell you in advance which items are likely to score
- An older building with no straps and unprotected openings may score nothing
The form is usually valid for a set period, so ask how long the result lasts and diary the expiry. It is only useful if the insurer receives it, so send it to your agent, ask for written confirmation the credits were applied, and check the next declarations page.
Do impact resistant shingles earn an insurance discount?
In many hail exposed states they do, and some carriers apply the credit automatically once they have the paperwork.
- The rating that matters is the impact classification from the UL 2218 test
- Class 4 is the highest, and the discount is tied to that documented class
- Not to a marketing description, so ask which classes your carrier credits
- Ask whether the credit survives at renewal and what evidence is accepted
- Ask whether it applies to the whole premium or only the wind and hail portion
Keep the product data sheet showing the classification, the invoice identifying the exact product, and the completion date, because a roofer who cannot supply the first has not installed what you think you bought. The rating describes a laboratory test, not a guarantee, and it does not change what your policy pays.
