Your roof is a big and mostly forgotten part of your home. When maintenance needs to be done on your home, it can feel like a daunting and expensive project. Especailly when youaren’t even sure what is going into the entire roofing system.

Luckily for you, we are here to help you understand the ins and outs of your roof. Let’s take apart your roof layer by layer so you can better understand the work that is done to protect your home from the elements outside.

Drip Edge

Drip edge is installed to control the flow of water at the edges of the roof. This is made with metal flashing and helps protect the fascia and the underlying parts of the roof.


Roof decking is an added layer of protection for the roofing system that acts as a base for all the roofing materials. At Irish Roofing & Exteriors we use OSB as our decking material.

Ice & Water Barrier

Ice and water barriers are placed in areas that are at a higher risk of damage from ice and water. Areas such as valleys and at the base of the roof.  


Roofing Underlayment is a waterproof barrier that is layed directly on your roof decking. This added layer of protection prevents damage from severe weather and storms.


Flashing is applied at joints of the roof, and it acts as a seal to prevent leaking and keep water out. Jointed areas of a roof might include valleys, skylights, and pipes. 


Asphalt roof shingles are the most popular roofing material used on homes across the board. Shingles are designed to protect a home through decades of weathering with minimal upkeep and come in a lot of different colors and styles.


Ventilation is a way for warm, humid air to be released from the attic. Ridge vents, soffit vents, and box vents are all common types of roof ventilation.
