Portals Plus manufactures solutions for roof leak problems.

Roof leaks are the biggest problem of architects and building owners. 85% of all roof leaks occur at penetrations and corners due to poor details which fail to accommodate movement. Extreme roof temperature swings require durable and flexible flashings. However, high labor costs and low common denominator standards create conditions for poor workmanship and non-functional field fabricated flashings.

A "good enough" attitude creates temporary expedients, such as pitch pockets or pans and their derivatives, but at the building owner’s ongoing expense. The National Roofing Contractors Association (NRCA) states that "Pitch pockets or pans by their design, are not intended to be continuously watertight. Their use should not be encouraged since better methods are available to accomplish the same end. Pitch pans or pockets require frequent inspection and maintenance, and usually a great deal of damage can occur before the leak around a pitch pocket or pan is evident."
