When considering to replace your roof, you will be faced with many different decisions and options. The main thing being the different types of roofing materials that you can choose. From traditional asphalt shingles or wood shakes to aluminum roofing or clay tiles, budget and style will be the primary deciding factors. But you also need to consider below:
8 Factors to Keep in Mind
Before you jump right in and start contacting roofing companies, you will need to consider the factors below to make a wise investment of replacing your roof.
Color & Style
Pleasing to the eye, color, & texture will all make up the appearance of the type of roof you want to install. Roofing options such as natural slate will have limited color options, while the popular option of asphalt shingles comes in many different colors. The main thing to keep in mind is your siding & brick color and how your roof will coordinate with these.
Energy Efficiency (R Value)
Want to save on heating and AC costs? Then you will want a higher R Value in your roofing insulation and roofing materials. The higher the R value the better. This translates to a more energy efficient roof. Asphalt shingles have an R value of around .45 while wooden shakes or shingles carry an R value of .97 or more than double its competitor. Here’s a useful R Value calculator for roofs.
Pitch (Angle) of Roof
The pitch of the roof (angle) can be a considerable factor when replacing your roof. The steeper the pitch the higher the cost of the roof installation and what type of roofing material you can use. Some roofs with such a steep pitch are not walkable and support structures have to be used to install the roofing!
Repair vs. Replace
So you have some roof damage, leaks, or some rough patches that need to be repaired? The question is do you repair or replace your roof? While no one can tell you what to do, roofs over 20 years old or dark patches on roofing may indicate the need for replacement. If you’re diligent to check your roofing every 2 years you should be able to spot potential damage and repair as needed until age takes over.
Timing, Noise, & Weather
Scheduling your roof replacement can be somewhat tricky. On the one hand, you want to maximize the full life of your current roof, on the other if you wait too long you roof can become compromised causing more structural and foundational damage which will cost more to repair & replace in the long run.

Know the Lingo (Anatomy of a Roof)
Before you dive in and begin talking with contractors and getting estimates, it would help to know the ins & outs of your roofing. Particularly the lingo of roof speak! Below is a simple graphic that outlines the finer details of a roof:
One of the most popular and cheapest roofing options available are asphalt shingles which make over 50% of all residential new roofing installations. Asphalt shingles can be either organic or fiberglass in composition. In both, asphalt is the outer layer of the shingle and the base will be organic material such as wood pulp or paper or fiberglass. Some of the more popular manufacturers of these shingles include CertainTeed, GAF, Owens Corning, & TAMKO.
Whether they are organic or fiberglass, they are 2 types of styles of asphalt shingles: three-tab shingles and laminate or ‘architectural shingles’. Three-tab shingles are a single layer shingle with ‘3’ tabs cutout. Architectural shingles have their lower part layered with an additional shingle which gives it a contoured and 3D look and feel when installed. Below are the pros and cons of asphalt shingles.
- Asphalt shingles are the cheapest roofing material available and easy on your wallet, costing $100 – $150 per square. (1 square = 100 sq. feet)
- Installing asphalt shingles is very simple, and in some cases a skilled homeowner can go down to home depot, buy the shingles, and install them on their own!

- Good fit for steep sloped roofs, and do well with any style of home and roofing.

- Finally, these are plain jane shingles, nothing fancy here
Metal roofing is a very attractive roofing option that has a solid combination of both eco-friendliness and a long-lasting lifespan. Although not that popular amongst residential homes, it is slowly making headway onto main street. According to the Metal Roofing Alliance, an approximate 5 million homes have some type of metal roofing and this number is growing every year.
