Are Tar and Gravel Roofs Good for Home Insurance?
Insurers treat them like any flat roof. They're fine if well maintained, but a problem once they near 20 years old.

The roof's age
A tar and gravel roof past 15 to 20 years is the usual reason an insurer non-renews or declines. The gravel surface hides wear, so the insurer may ask for proof of condition rather than take the roof's age alone as the answer.
What dropped you
The non-renewal letter should name the reason. If it's the roof, that's a different problem than a claims history issue or the insurer pulling back from the area. A roof certification fixes one. Shopping for a new carrier fixes the other.
An inspection or certification
A roof certification from a contractor or inspector, stating the remaining life and condition, can satisfy an insurer that would otherwise decline a tar and gravel roof. This is often faster and cheaper than a full replacement.
The deadline you're working against
Your letter gives the exact date coverage ends, set under your state's notice rules. If a lender requires coverage, getting a new policy or the roof documentation sorted before that date matters more than finding the cheapest option.
Insurers don't all weigh a tar and gravel roof the same way. One company may decline it outright at 18 years while another accepts the same roof with a current certification in hand. Since the letter's deadline is fixed, comparing how different insurers treat your roof's age and condition is the fastest way to find coverage before it ends.
What happens to the roof itself once you're covered
A tar and gravel roof that passes inspection still needs upkeep the policy doesn't spell out. Standing water is the main enemy. Flat and low-slope roofs rely on proper drainage, and gravel can shift or wash into drains over time, creating pooling that wears the membrane faster than age alone would. An insurer that accepts the roof today based on a certification may not renew that view in three years if the same drainage problem shows up in a claim or a follow-up inspection.
Granular loss is the other thing adjusters look for. The gravel layer protects the asphalt underneath from UV damage, and bald patches mean that protection is gone in spots even if the rest of the roof looks fine. A contractor doing a certification should note this specifically, not just give a general pass. If you're the one scheduling the inspection, ask that the report mention drainage and surface coverage, not just overall age, since that's the detail an underwriter is most likely to ask about later.
Repairs matter too. A tar and gravel roof patched piecemeal over the years can still function well, but insurers sometimes treat a heavily patched roof the same way they treat an old one, as something that needs its own look rather than a pass based on the rest of the house. If you've had patchwork done, keep the invoices. They're evidence of maintenance, which works in your favor the same way a certification does.
None of this changes what coverage itself pays for. Dwelling coverage on your policy is what rebuilds the house, including the roof, after a covered loss like fire or wind. It has nothing to do with whether the insurer will write or renew the policy in the first place. Those are separate questions, one about risk and underwriting, the other about what happens after damage. Keeping the roof documented addresses the first. Reading your declarations page for what rebuilding cost it assumes addresses the second.

Before you shop
Check your letter for the exact date coverage ends, and get a roof certification scheduled now if the roof's age is the stated reason. Having that document in hand before you compare carriers changes what they'll offer.
