How much rain can a Gutter Helmet® system handle?
The angle of a roof is called pitch. Gutter Helmet® has engineered a variety of installation techniques to work on any pitch roof, from flat to almost vertical. Rest assured that rainwater will flow into your Gutter Helmet®-protected gutters, regardless of the pitch. Many products on the market promise their systems will handle 22″, 24″, or even 30″ of rain per hour; but what does that mean? Actually, almost any product can handle large amounts of rain if it is installed on a relatively flat roof with a very short roof run. For example, Gutter Helmet® could claim to handle 109″ per year, a very true, but very misleading statement (very low pitch with a 5 foot roof run). The fact is that it has never rained more than 12″ in a single hour in the US.
