Why Insurance Companies Send Roof Requirement Letters

Insurance companies periodically review the properties they cover, either through aerial imaging technology, routine underwriting audits, or after a claims review. When they spot a roof that shows signs of significant deterioration, they issue what's called an underwriting requirement — a formal notice that a specific condition must be corrected to keep the policy in force.

What is an underwriting requirement?

Underwriting is the process by which an insurance company assesses the risk of insuring your home. An underwriting requirement is simply a condition they've set that must be met in order for coverage to continue. Think of it like a vehicle inspection — if your car fails, you have to fix the identified problem before it can be registered. Similarly, if your roof fails the insurer's standards, they require it to be replaced before they'll continue covering your home.

What is granule loss and why does it matter?

Asphalt shingles are coated with small mineral granules that protect the underlying mat from UV rays, rain, and impact. Over time — typically 15 to 25 years depending on the product — those granules wear away. The letter you received likely mentions "granule loss" as the specific reason for the requirement.

Granule loss isn't just a cosmetic issue. Once the protective coating is gone, shingles become brittle, crack more easily, and are far less effective at shedding water. This dramatically increases the risk of interior water damage — which is exactly what your insurer is trying to avoid paying a claim on.

What Happens If You Don't Replace Your Roof in Time?

The letter is serious, but it's not a cancellation notice — not yet. It is a warning that your policy will be set to non-renew on a specific date unless you comply. Understanding the difference between non-renewal and cancellation matters.

Non-renewal vs. cancellation — what's the difference?

A cancellation means your coverage stops before your current policy term ends. A non-renewal means your insurer will not offer you a new policy when your current term expires. In practice, both outcomes leave you without coverage — but with a non-renewal, you typically have until your policy's expiration date to find a replacement carrier or comply with the requirement.

The bigger risk: if you let your policy lapse, you may be forced into a higher-risk insurance pool, face significantly higher premiums, or find it difficult to get coverage with a standard carrier at all. If you have a mortgage, your lender will likely purchase forced-place insurance on your behalf — at a much higher cost to you — if your coverage lapses.

How long do you typically have to comply?

Most underwriting requirement letters give homeowners between 30 and 90 days. The specific deadline will be printed clearly in your letter — look for a date that the policy is "set to non-renew effective" if documentation isn't received. Start the process as soon as possible, as roofing contractors can have scheduling delays during busy seasons.

What documentation does your insurance agent need?

Once your new roof is installed, your roofing contractor should provide you with a completion certificate or invoice showing the date of installation, the materials used, and the contractor's license information. Submit this directly to your insurance agent — not the claims department — as soon as the job is done. Many insurers also accept a photo report.

Eligible Roofing Materials — What Your Insurance Company Accepts

Your letter specifically states that "eligible roofing material must be used." This is an important detail. Not all roofing materials are created equal in the eyes of your insurer, and choosing the wrong product could mean your replacement doesn't satisfy the requirement — or worse, results in a higher premium than necessary.

Most major insurance companies now prefer or require a Class A fire rated and impact-resistant roofing materials, rated typically by Underwriters Laboratories (UL) or FM on a scale from Class 1 to Class 4. Class A fire rating is the highest level of fire resistance for building materials, particularly roofing, according to industry standards and recognized by insurers like State Farm. Class 4 is the highest rating and offers the most resistance to hail and wind damage.
