Preserving Your Roof: Drip Edges And Their Benefits

Most asphalt roofing structures last approximately 15 to 30 years before they need to be replaced entirely. Replacing the entire roof can be rather costly. Due to this reason, many roofing contractors will recommend implementing different tactics that can help preserve the integrity and condition of the roof, especially from elemental and environmental conditions. Drip edges, in particular, are highly recommended due to the numerous advantages that they bring to the homes. This article will introduce what drip edges are and the benefits that they provide.

The drip edge is a piece of metal flashing or any other type of overhanging component that has an outward projecting edge from the roof.

Most roofing contractors would recommend installing a drip edge that extends beyond the fascia board by at least 3/4 inch, so that the runoff water will undoubtedly drain off into the gutters.

Drip edges are normally installed underneath the first row of shingles. Some roofing contractors may leave the shingles extra long, so that they form a type of outward projection into the eavestrough instead of installing drip edges. While this is a short cut that may cut down on labor costs, it is not beneficial to homeowners in the long run since the shingles will eventually weaken due to the added stress that it experiences. This will accelerate the rate of deterioration, and also hinder proper installations of any new eavestrough in the future.
