There are many elements to residential roofing such as the parts, designs, and materials.
Then there is also the maintenance, repair, and replacement.
The physical aspects of a roof, the significance of roof maintenance and how to do it, and how to recognize the need of a repair or replacement and the costs.
Every homeowner should be familiar with the basics of residential roofing to know how to properly maintain their roof.
Important Parts of a Residential Roof System
There are multiple layers to a residential roof, each with a different purpose in protecting the house.
These layers can help protect against weather, temperature, and additional weight put on the roof.
Here are the major parts of a residential roofing system:
- Roof Covering – The top layer of the roof is the covering. One of the most common forms for a covering is shingles, but it can also be metal, clay, slate, wood, and more.
- Underlayment – This is the layer underneath the roof covering providing additional protection from weather damage.
- Sheathing – A strong base of wood boards that are attached to the trusses and joists of your roof. It prevents any bowing or sagging from the heavy weight of snow, water, or additional shingles. It helps distribute weight across the roof by covering the whole roof and is secured to the strongest beams.
- Flashing – The roof’s flashing directs precipitation away from sensitive areas of the roof and towards the gutters, preventing leaks.
- Ventilation – Roof ventilation can be set up mechanically or naturally, allowing air to flow through the attic to maintain the indoor temperature and prevent moisture.
- Roof Drainage – Drains are usually located at the lowest point of the roof with the purpose of moving excess water from the roof’s surface and preventing water damage.
5 Popular Roof Designs
Roofs come in many different shapes and sizes. The designs can be simple or complex.
Here are some of the most popular residential roof designs:
- Gable – This roof design is known as a peaked or pitched roof. It has two pointed slopes connected to each other in a triangular shape.
- Hip – The hip roof has four sides creating a rectangular look. The front and back facets are longer and are connected by narrow side facets that are the “hips” of the roof.
- Jerkinhead – This can sometimes look different but to be considered a Jerkinhead it has to have clipped peaks. Clipped peaks are when two sides come to a point and the point is flattened into a small triangular facet.
- Gambrel – The most common gambrel roof design has two symmetrical sides, each with two slopes, one slope steeper and one slope shallower.
- Mansard – A mansard roof has four sides, two slopes on each side, with one slope steeper and one slope shallower.
Common Materials Used for Residential Roofs
Materials used for the roof covering can give a house a whole new look and provide many benefits.
There are various types of roof covering materials such as:
- Asphalt – One of the most common and reliable residential roofing materials. Asphalt shingles are durable, relatively affordable, and simple to install with a lifespan of up to 25 years.
- Slate – Slate is rot-resistant, fire-resistant, and easy to maintain with a lifespan of 100 years.
- Metal – A metal roof is easy to maintain, lightweight, eco-friendly, and has a lifespan of 50 years or more.
- Clay Tiles – Clay tiles are durable, fade-resistant, fireproof, and come in many shades, shapes, and sizes with a lifespan of 50-70 years.
- Wood – Wood shakes are eco-friendly and can provide natural insulation that can reduce energy costs. It has a lifespan of 40-50 years.
The Importance of Roof Maintenance
Though routine care of a roof can cost money throughout the year, it’s not much compared to a sudden roof repair or replacement.
Residential roof maintenance is about taking preventative measures, providing you the peace of mind and security that any issues found during a routine check are being taken care of.
But without the occasional maintenance, those small issues could become larger issues later on, and even shorten the roof’s lifespan.
