Are Flat Roofs Hard to Insure?
Yes, since flat roofs drain poorly and wear faster, so insurers charge more or decline them, especially if the roof is older.
Free to compare
If a flat roof is behind your non-renewal, the insurer is likely reacting to the roof's age and history rather than the house itself. Flat roofs typically need replacement sooner than pitched ones, and pooling water causes leaks that show up as claims. Your declarations page and any inspection notice will say whether the roof itself was the stated reason. A recent replacement, with documentation, is the strongest thing you can bring to a new insurer. Without that, expect fewer insurers willing to write the policy, and a higher price from the ones who will.
Insurers who won't touch an older flat roof aren't all pricing it the same way. Some decline it outright, others charge more for the same coverage, and a few will write it fairly if the roof was redone recently. With a deadline on your current policy, the difference between those outcomes is worth checking before coverage lapses and your lender starts asking questions.
What can be done about the roof itself before shopping for coverage
An inspection from a licensed roofer carries more weight with an insurer than your own sense that the roof is fine. Ask for something in writing that states the roof's condition, remaining life, and any repairs needed. Some insurers will reconsider a decline, or improve a price, if that inspection shows the membrane and flashing are sound even though the roof is older. Without that paperwork, an insurer has only the roof's age to go on, and age alone tends to work against you.
If the inspection turns up problems, fixing them before you apply is usually worth more than the cost of the repair. Pooling water, worn seams, and soft spots around drains are the things insurers hear about most often as claims, so a roofer who addresses those gives you something concrete to point to. A full replacement resets the clock in a way nothing else does, and insurers that decline older flat roofs outright will often look at a new one.
The roofing material matters too. Older flat roofs are often built with tar and gravel or roll roofing, materials insurers associate with shorter lifespans and more leaks. Newer systems like TPO or EPDM membranes tend to hold up longer and drain better, and some insurers price those differently even on a roof that isn't brand new. If you're replacing the roof anyway, ask the roofer what material the insurer is likely to view more favorably, since that answer can vary by region and by roofer.
None of this guarantees a lower price or a yes from every insurer, since each one weighs roof age, material, and claims history differently. What it does is give you something to bring to the conversation besides the bare fact that the roof is flat and old. An insurer deciding between a decline and a policy often has room to move if you can show the roof was inspected, repaired, or replaced, and documentation is what makes that case.
Does the type of house matter, or is it just the roof
Insurers look at the roof first because it drives most of the risk, but the rest of the house still factors into the decision. A flat roof on a converted commercial building or a rowhouse reads differently than the same roof on a detached single-family home, partly because of what sits underneath it and how water damage would spread if the roof failed. If your non-renewal letter named the roof specifically, the house's other features probably were not the deciding factor, but they can still affect which insurers are willing to write the policy at all.
Age of the house interacts with age of the roof in ways that compound the problem. A roof that is twenty years old on a house with original wiring or plumbing gives an insurer two reasons to decline instead of one, even if neither issue alone would have triggered the letter. If your house has had other updates, electrical panel, plumbing, HVAC, it's worth having that documented alongside the roof inspection, since it tells a new insurer the risk is isolated to one component rather than spread across the whole structure.
Location plays a role too, separate from the roof itself. Flat roofs are more common in regions with certain architectural styles or climates, and insurers pulling back from an area often do so because of broader exposure, wildfire, hail, hurricane risk, not the roof specifically. If your letter mentioned both the roof and a change in how the insurer is writing business in your area, the roof repair alone may not be enough to get the same insurer back, though it can still help with others.
None of this changes what to bring to a new insurer. The roof documentation matters most because it was most likely the stated reason, but a complete picture of the house, age, systems, any other recent updates, gives an insurer more to evaluate than the roof in isolation. A house that looks well maintained overall makes the roof's age a smaller factor in the decision, even when it was the reason the previous policy ended.
Before you apply again
Check your declarations page or non-renewal letter for the exact reason given, then get the roof inspection in writing. That document, more than anything else, is what a new insurer will want to see first.
