How to Use a DIY Flat Roof Kit

While installing a flat roof is a job that is often best left to the professionals, there are certain times when installing your own flat roof might be an ideal option.

There are a number of different flat roofing options, but one of the simplest, most effective ways to go about installing your own roof is by using a flat roof installation kit; essentially a flat roof in a box.

If you’re interested in installing your own roof, and wondering what it involves, here are some things that you should know.

Flat Roofing Basics

Flat roofs are comprised of joists stretching over the gap between the walls. The gap is then covered by sheet timber or another material and your roofing materials. The type of materials that you use, along with the roof’s dimensions will determine how strong the supporting joists need to be. Keep in mind that a flat roof has to be strong enough to hold a significant amount of weight such as snow buildup at certain times of the year. There are also building regulations, which must be met.

Choosing a DIY Flat Roof Kit

The preparation process involves more than just picking up a DIY flat roofing kit, it’s usually best to receive professional advice about your roof’s support structure, and about which kit is right for you. Many flat roof kit suppliers provide advice, and it’s worth emailing them and asking them about which kit is right for your needs.

DIY Flat Kit Prep

While there are multiple options available when it comes to flat roofing materials, one of the most common (and easiest for DIY projects) is single ply membrane. The single ply membrane is reliable, stable, and easiest to install. Remember when measuring for the materials needed on your roof, round up, not down. If all of your underlying supports, roof boards, joists, or woodwork are in good condition, you most likely won’t have to replace them, and instead you can simply strip the old materials off and apply the new. However, if the boards or joists need to be replaced, you shouldn’t skip over this important step, as this will just cause problems in the near future. You should be sure to have a strong water-based adhesive available to ensure a tight seal. While your DIY kit should include this adhesive, you should have extra on hand, just in case you need more.

Installation Process

The installation process shouldn’t take longer than a day. Once you have all the old materials removed and the foundation for the roof inspected and supports replaced if needed, then the installation process can begin. If you have chosen to go with single ply membrane, you should be sure to have a hot air gun available as well. You should be able to rent these for a short period of time. Adhesives that are heat activated are among the best for ensuring that the membrane is installed to be durable and leak free.

A flat roof DIY installation, if done correctly, can help to cut down on the costs involved with the installation process. But it’s important to keep in mind, that if you have any doubts regarding the installation process, you should probably call in the experts. Having your roof installed correctly the first time can help to save you money in the long run.
