*Gross linear foot refers to the combination of both the gutter and spouts in per foot lengths. *Preventative maintenance is imperative to helping your roof reach the full potential of it's life and all warranties associated with its installation. Locating any failing or damaged water penetration points are the primary goal of an inspection. During a typical inspection we often find rubber seals, exposed nails, flashings, and multiple types of sealant materials that are in deteriorating condition and are or will soon allow water to penetrate the roof surface which ultimately causes or is causing damage to the interior of the home. On the rare occasion if you have a large population of birds, ants, or squirrels in your area their actions can cause damage that leads to penetration points as well. If you will, for a moment, set aside the old adage that states "don't fix it unless it's broken", then it will be easy to see that a home does not fall into this category and it is imperative that any possible failing points are identified and ultimately repaired before the exterior damage or damages extends into the interior of your home. *When the gutters are impaired the water fails to flow appropriately and can back up and penetrate the roof surface from beneath the drip edge especially in the winters when the water turns to ice and expands. *Debris resting on a roof surface can stay saturated with water which extends the duration for which water is meant to rest on the roof surface. This situation can cause mold, mildew, and even dry rotted to form beneath it which is directly against the protective service of the roof and can cause undo early deterioration of the product. Debris such as leaves, Sticks, and even toys, can come to rest in critical places such as valleys, dead valleyes, and along flashing walls where the roof of the home takes on the most water flow and puts the home at greater risk of penetration points being created and damage to the interior of the home becoming a possibility.
