The process of how to install roll roofing on low slope roofs is not difficult, but there are a few basic elements that need to be understood and practiced. First of all, if the roof is being installed over a pool or any other area that is permanently or temporarily covered, make sure that the slant is downward. This will prevent water from penetrating the roof and doing damage. If pools are present, they must be drained before beginning work. If not the whole roof may have to be removed from the ground to allow access for the workers. It would also be wise to seek professional assistance with this part of the project.
Once the roofing material is installed, you will need to channel it properly. The process of how to install low slope shingles begins with ensuring proper alignment to the building. It is important that the slant extends downward and outward at least twelve inches and that the pitch is equal to the height of the building. In most cases the angle should be about forty-five degrees. If you are unsure of how your shingle installation will affect the slope of your roof, you can contact your local building department for assistance in that regard.
The second step of how to install low slope roofs is to nail all of the pieces together. Most building supply stores carry roofing nails in varying sizes. Make sure that you purchase nails that are heavy duty to resist corrosion. When installing, it is important to nail all of the nails straight down through the shingles. Nails that are crooked will eventually lead to more problems than they are worth. Also, keep in mind that if you do use nails that are crooked you must sand them down before using them again to ensure that they will work properly in the future.
The third step on how to install roll roofing on low slope roofs is to prepare the area to be covered by the membrane. This preparation should be done prior to sealing the seams of the membrane and applying the adhesive. First, make sure that all nails are driven in the right direction. After ensuring this is all done, you can move on to the next step of covering the low slope roofs. Apply the primer to the area by scraping it lightly with a knife or razor blade.
The fourth and final step in how to install roll roofing on low slope roofs is to tack the sheets together. Prior to tacking, make sure that the nails are driven in the correct direction. After installing the first few nails, drive the nails evenly into the concrete. Continue installing the nails until you reach the final screw. Once this step is complete, you can then apply the final primer to cover any areas that may not be visible due to the rolled edge of the membrane.
Installing roll roofing is not a hard job. It just requires proper preparation and planning. If you do not feel confident with your ability to install this type of roof, call a professional to do the work for you. You will be glad you did when your low slope roofs last for decades.
