The importance of placing drippers before installing asphalt tile

 

The roofs are usually affected by dust, humidity and pollution since they are exposed to the open air, so in the rainy season they are affected by the increase in humidity. An alternative so that the walls or the roof does not become damaged over time is the application of drippings on the eaves (edges) of a roof.

‍

What is a dripper?

‍

A dripper is a piece of galvanized sheet that will not stain or corrode and is installed on the edge of a roof to give water the ability to seep out of the roof system. The dripper is installed with a planned slope, which is specifically designed to divert water from a roof while ensuring that your roof's foundation is not prematurely depleted by holes or cracks.

‍

A dropper can be made of light metal such as galvanized sheet or 26 gauge pinto sheet. It can also be made of PVC or some modified plastic resistant to the environment (exposure to sun and rain).

Profits

• Drippers not only act to preserve the appearance of your roof, but also help protect your property from potential moisture damage.

• At the edges of the roof, drippers are installed under asphalt shingles and asphalt felt, preventing water from seeping into vulnerable areas below them.

• The drippers support the protruding asphalt shingles, keeping them in a straight and stable line.

• Asphalt shingles without drippings can not only be damaged, but they also don't look very sharp.

Styles

Drippers come in a variety of shapes and styles. The most common are T and L.

‍

The L- style dripper is used on low-pitched roofs, is bent at a 90 degree angle and has a flange at the bottom.

‍

T- style drippers have an additional lip that actively guides water out of the house. Unlike the L style , they do not bend at a 90 degree angle. This style extends beyond the roof deck and bends into the house in a triangular shape, this type of drip is the most effective used by contractors.

Installation

‍

To install a dripper on a newly constructed roof or re-roof job, you will need to place it along the eaves of the roof. Eave drip is installed before asphalt felt or asphalt shingles.

‍

Position the drip starting from one corner, aligning it over the eave so that 1 inch of the drip extends beyond the edge of the roof. Begin nailing every 12 inches or so. When you place the next piece, it should overlap the first one by one inch.

‍

It is crucial to avoid creating gaps as it can cause the water to drift under the drip instead of flowing over it. Therefore, when joining two dripper pieces, be sure to overlap them. As mentioned above, the minimum required measurement is 1 inch.

‍

For its placement, it is fixed with a 1 ”to 1 ¼” nail either for wood or concrete depending on the material with which your roof is made. It can also be fixed with a flat head pin from 1 "to 1 ¼" and a screwdriver or drill for greater comfort and speed when it is rock or concrete.

‍

Once you've covered your eaves with drippings, it's time to install your synthetic roof covering. 

‍

Installing roof drippers ensures that the interior of your home remains dry, is also inexpensive, adds a nice profile to the facade, and protects the wood framing underneath the asphalt shingles. Hope this tip will help with your roof knowledge. Toodles!‍
