As a homeowner, one of the most expensive home repairs that you can undertake is a roof replacement. In this article, we’ll tell you the most important factors in opting for a reroof or a roof replacement, and the difference between them.

Most Common Types Of Residential Roofing Materials

Typically in residential roofing, three types of roof material are standard for use. They are asphalt shingles, slate, and metal roofs. The most common material is asphalt shingles, which are the least expensive option of the three, but also have the shortest life span. A shingle roof has a lifespan of somewhere between 15-30 years after a new installation.

A metal roof is your mid-range price option in residential roofing and usually is sold with a guarantee somewhere between 20 and 50 years that the material will not fail. It is much lighter weight than shingle or slate roofing, and if it is installed properly, it will usually last the life span of the house it is installed upon. Although the sound of rain hitting the roof is a distraction for some, most of the time homeowners are greatly satisfied with their choice to install a metal roof because it is a lifetime roof with a price tag that is still manageable by the average homeowner.

With a slate roof, you have an average life span of 150 years. It is loved for its beauty and classic look, but the overall cost is astronomical in terms of residential roofing. It typically runs between $1,500 to $2,000 per square (1 square = 10x10ft). One downfall to having a slate roof is because the tiles come in lots, it is nearly impossible to find a replacement for a broken tile that will match the other roof tiles you have. This means in the event a tile is broken or missing, you will more than likely have a tile that is visibly a different color than the rest of the shale tiles on your roof. However, slate has a water absorption rate of .04%, making the material virtually waterproof and perfect for roof tile material.

What Is A Reroof?

In a reroof, new shingles are layered over the existing shingles in place on your roof. This can only be done once, equaling 2 layers of shingles, but after that, a roof replacement must be performed instead of another reroof. Reroofing is done in an effort to get the last few years out of an existing roof and often gives the homeowner a window to save money to have a roof replacement performed.

Most times, if a roof is nearing the end of its life span, but still in overall decent shape, a reroof can take place. It will, most of the time, repair minor issues like leaks that are localized. However, in the case of mossy or mildew growth that is heavy on the roof, soggy or obvious soft spots in the roof, or missing patches of shingles, a roof replacement will be necessary.

What Is A Roof Replacement?

In a roof replacement, everything is torn down all the way to the decking. Any wood rotted or otherwise water damaged decking is replaced, then new felt paper is put down. After that, a single layer of shingles is laid, and the caps and ridges are put in place. A roof replacement is typically a great deal more costly than a reroof, with a roof replacement around double the cost of a reroof.

However, reroofing can hide wood rot or sagging decking under the shingles, so if a leak has been left unrepaired for any significant time period, it is often a wiser choice to perform a roof replacement so that the decking can be inspected thoroughly prior to installing any new shingles. If your roof is at or approaching the 20-year mark, it is probably going to be a better choice to proceed with a roof replacement because of the change of developing leaks in other areas of the roof because of its age and wear.

In summary, when you choose a roof replacement, try to opt for the highest grade roof material you can afford, and ensure that it is properly installed by licensed roofers to ensure that you get maximum mileage out of your new roof.
