Charlotte Roofing: Article About Benefit Of A Drip Edge
Some roofing contractors may argue that a drip edge is optional. When attempting to cut costs, it is usually the first thing removed from a roofing quote. Reputable Charlotte roofing experts disagree. A drip edge, the metal flashing that roofers install under the first row of shingles, is a crucial part of any roofing system.
A drip edge is designed to support the shingle overhang and guide water away from the roof and walls towards the rain gutters. A drip edge should extend at least 1 inch beyond the edge of the roof in order to work properly. Although some contractors insist shingles can be positioned to create a drip edge without metal flashing, they will eventually bend and break if they extend more than 3/4 of an inch beyond the edge of the roof. This can create a number of problems for the homeowner.
A roof that does not have a drip edge is at risk of water seepage and pest problems. Without a drip edge, driving rain can push water under the shingles and damage the sheathing, deck, and even the end of the rafters. Under normal weather conditions, a home lacking a drip edge cannot properly channel water from the roof into the gutter. Water that runs between the wall and gutter will discolor siding, erode soil, and flood the basement.

A drip edge also creates a barrier for insects and rodents. Without a drip edge, there is often a gap where the first row of shingles extends over the fascia. This gap makes the perfect entry for insects. Rodents, including squirrels, may notice the gap and instinctively chew at the structure to make a larger hole to gain entry to roof. Nesting rodents can create a huge pest problem and substantial structural damage.
The exact method of drip edge installation will differ depending on manufacturer's suggestions and local building codes. Some building codes require the drip edge to be installed under the sheathing. Other building codes require the drip edge to be applied over the sheathing. Either way, it is best to invest in quality materials instead of trying to cut corners. Roofing experts often recommend a drip edge that is made from aluminum or galvanized metal.
It's important to discuss the installation of a drip edge when negotiating with a roofing contractor. Although eliminating a drip edge can save money during the initial bid for a roofing project, the consequences of foregoing this structure will cost the homeowner in future repairs.
