No, metal roofs don't inherently leak more than shingles; in fact, properly installed metal roofs are often more resistant to leaks due to fewer seams, greater durability, and interlocking designs, outperforming shingles, which can fail from curling, cracking, or blow-offs over their shorter lifespan, leading to more potential moisture issues over time. The key factors for leaks in both materials are installation quality, maintenance, and age, not the material itself.
The idea that metal roofs leak more than shingles is a misconception that fails to account for the superior performance and durability of modern metal roofing systems. With proper installation and maintenance, metal roofs can provide reliable leak protection and long-term value for homeowners.

Even when sealant is applied, screws that are not driven in properly, driven in too far, or put in at the wrong angle can all create openings for moisture to seep beneath the metal panels.
5 Problems With Installing a Metal Roof Over Shingles

Actually, when a standing seam metal roof has a leak, it is commonly at some type of flashing area. Failed sealant or butyl tape – Sealants and butyl tape are used to seal out water, dirt, and other debris that could compromise a metal roof.

Homeowners insurance typically covers roof leaks that result from sudden, accidental events like storms, falling trees, or hail damage. Situations that are typically covered include: Hailstorms, which can crack or puncture shingles and roofing materials. Wind, which may tear off shingles or lift roofing components.

Wind: Metal roofs can withstand up to 140 mph winds (or higher when properly fastened) Fire: Metal is Class A fire-rated, unlike shingles made from flammable petroleum products. Hail & Ice: Metal panels shed snow and ice more easily, reducing ice dam risk.
The biggest problem with metal roofs is poor installation, leading to roof leaks, premature deterioration, and energy inefficiency. Many homeowners report that improper fastener placement, misaligned metal panels, or lack of a moisture barrier can lead to water infiltration—especially around seams or protrusions.

No, it is not normal for a properly installed, good-condition roof to leak in heavy rain; leaks during downpours reveal underlying problems like damaged shingles, failing flashing (around vents, chimneys), clogged gutters, or poor installation that intense water flow and wind expose. While a roof is designed to handle rain, heavy storms act as a "stress test," pushing water past weak points that might not show up in lighter rain, leading to leaks from cracks, gaps, or compromised seals.
That's because the risk of an insurance company having to cover a roof replacement due to storm damage is minimal. In fact, insurance companies cover metal roofs and often offer a discount for their installation.
We've been in the metal roofing business for nearly 20 years(installed for 10, now just do sales and distribution), and usually, those neoprene washers will last longer than 5 years. Ive been on roofs that have had metal on for 8-10 years and the washers still looked good.
