Benefits of Using Rolled Roofing

There are many reasons property owners use this material for roofing. Some of them include:

1.     It is Cheap

Some property owners may have a low budget that cannot purchase asphalt shingles to repair their non-residential roofs. With this material, they do not have to stress about spending the equivalent amount.

Rolled roofing is a cheap option, and one can hardly hurt their budget with this option. Also, installing it is super easy, and contractors do not ask much. Actually, most homeowners install them in DIY projects with the help of their friends.

2.     Quick Installation

Unlike shingles, where the contractor has to lay each at a time, rolled roofing is quick to install. It comes in rolls, and the contractor only has to fix it from one point and then roll it over the area they want to be covered.

Besides, installing this material does not require removing the existing one, as long as it is in good condition. Typically, the time that could have been used to remove the old material is also reduced.

3.     Used in Low-Inclined Roofs

Property owners can find it challenging to find materials compatible with low-sloped roofs. Luckily, you can use a rolled roof for the work. The minimum slope declination you can use with this material is 1 inch for every 12 horizontal inches.

There is a catch, though. For such low pitches, concealed nailing must be done to fasten the roof.

4.     Easy to Transport

You do not have to use professional transporters to transport this material. Because it comes rolled while new, no special tools are needed for handling. With your private truck, you can transport it to where your project is and start installing.

5.     Easy to Repair

It can take a while to note a roofing material is damaged. Often, it takes a while, and when we realize it, mold and mildew would have started growing. But, with rolled roofing, it is easy to identify and repair before the mess occurs.

Identifying it is easy because an imperfection in the smooth and continuous material stands out.


With so many benefits to enjoy from this roofing material, it also has its shortcomings. They include:

1.     Not Durable

If you are looking for a roofing material that will serve you for long, sorry, but it is not the best option. Rolled roofing has a short lifespan, about 10- 15 years.

2.     They Are Not Aesthetic

You cannot rely on rolled roofing for your property’s curb appeal. It comes with limited color options. Also, since it is a roll, it does not have a provision for design options.

If it is your first time using rolled roofing, it can be confusing about how to roll it and whether it is worth trying. Provided your area code does not have a problem with it, you can consider it for your non-residential property.
