Essential Component of a Residential Roofing System

Essential Component of a Residential Roofing System

Every roof is made up of more than one layer of shingles, tiles or metal. It is a whole combination of several parts that are brought together to help protect your home from the weather and other elements, keeping your assets and dwellers safe and comfortable. When discussing residential roofing systems, several parts are very dynamic in keeping the system solid. 

What Are The Essential Parts of A Roofing System?

Below are some of the essential parts of a residential roofing system. These parts should be well taken care of, and even before construction, make sure the materials for setting up these parts are of good quality.

Trusses – The truss is recognized as the backbone of a roof. This is what provides the roof of its structure. The setting of the truss dictates how materials are laid on your roof. Many materials can be laid on steep slope roofs, but some other materials would do better on shallow slopes. Rafter is also part of the trusses, and the part where the decking material is attached to is also part of the trusses.

Decking – The outer surface of a roof depends on the deck for balance. Materials used for decking are plywood or oriented strand boards (OSB). During a roof replacement project, the outer roof is removed down to the decking layer, and if this part is in good condition, it won’t be replaced. The attic area is often used for foam installation. This is mostly done when the attic space is already converted to a roof.

Underlayment – Another name for this is called roofing felts. This is a waterproofing material inserted on the roof deck before the outer roofing layer is laid or installed. Before now, underlayment materials were old asphalt saturated paper. Nowadays, roofing material production companies are making their materials that suit their roofing systems. The best of these recent materials are those that allow moisture generated in the roof to be released outside for evaporation.

Starters Strips – Unannounced, the roof edge can be torn off by wind or storm. This is why an additional layer of roofing installation is recommended to be installed at the edge of the roof (this recommendation is for traditional roofing systems). At the same time, most modern roofing materials have starter strips built from a later roll of material. Adhesives are used to fasten roofing nails. They create an impenetrable layer that helps to keep the roofing firm even in times of heavy storm.

Attic Ventilation – The importance of keeping moist air and hot air out of the home cannot be overruled. The attic is installed for this purpose. Trusses and the roof decking will be in jeopardy if moisture and heat are trapped in the roof. Professional roofers would tell you the importance of good attic ventilation to your roofing system. When you plan on getting a roof installation for your home, these parts should be discussed with your contractor. Every other part will get affected if this is not treated fine. 


All these listed parts of a residential roofing system are essential. If you need your roof to last longer, and stay strong, keep these parts in check and call for immediate repair if it is going bad.
