Flat roofs are versatile and can be used in various buildings, from homes to commercial structures and warehouses. Over time, these roofs can suffer from significant wear and often face issues with ventilation and drainage, particularly if they need to be properly installed and maintained.
Fortunately, their maintenance and installation are straightforward. Even if you’re new to roofing, you can try replacing an old roof and fitting a new flat one relatively easily. It’s best to install your flat roof under the guidance of a roof expert with the right skills and knowledge. The time, tools, and risks involved often outweigh the financial savings compared to hiring a professional roof company.
Nevertheless, there’s no stopping for DIY enthusiasts willing to install a flat roof on their own! We believe you should know the ins and outs of flat roof installation before you leap into the task. So read on!
Is DIY Flat Roof Installation Safe?
Regarding the safety aspect of replacing your roof, it’s crucial to consider your well-being and the roof structure’s integrity. Focusing on personal safety, it’s important to recognize that roofing can be hazardous without proper precautions. Professional roofing contractors are adept at working on roofs and consistently use safety equipment during their work. This equipment includes harnesses, hard hats, gloves, protective eyewear, and appropriate work attire. Without the right gear and skills for navigating a roof, the risk of slipping and sustaining an injury significantly increases, which is clearly detrimental.
Types of Flat Roof Material
Flat roofs come in various types based on structural characteristics, insulation, waterproofing, and roofing materials. These include:
- Cold roofs, where insulation is placed between the joists.
- Warm roofs, with insulation above the joists.
- Inverted roofs, where the waterproofing membrane is situated beneath the insulation.
- Hybrid flat roofs have additional thermal insulation.
- Additionally, there are curved, tapered, and green flat roofs.
Each type of roof requires specific installation techniques. For comprehensive information on installing these different kinds of roofs, it’s best to consult with professional roofers.
Choosing a DIY Flat Roof Kit
When considering a DIY flat roof kit, remember it’s about more than just grabbing the first kit you see. Understanding your roof’s support structure and determining which kit suits your specific needs is crucial. A great tip? Reach out to suppliers of flat roof kits. Most of these suppliers are more than happy to offer their expertise. Sending them an email with your questions can make a huge difference in choosing the right kit for your project. Remember, professional advice can go a long way in ensuring your DIY roofing success!

Step-By-Step Flat Roof Installation Guide
Remove Your Old Roof
When replacing an existing roof, the initial step in putting in a new flat roof is to remove the old one. You’ll need to strip it down to the base layer, being careful not to damage any existing flashing, trim, or valleys. Inspecting for any necessary repairs before installing the new roof is important. To remove your old roof:
- Begin by removing the gutters and fascia to expose the roof underneath.
- Use a spade to break through the layers of old roofing materials like felts, fabrics, and mats.
- Manually remove the mortar from around the edges.
- Use tools like a bolster, hammer, or wallpaper scraper to remove any remaining materials.
- Take off the old roofing felt and any poorly placed nails.
- If there are timber filets, remove them using a spade or a pry bar.
Evaluate for Damages and Repairs
Once you have removed your old roof, the next step is to inspect your roof for any damage. In cases where standing water has caused damage, remove the roofing material and any rotten wood in that area. If the wood is still in good condition, use roofing tar to level the area before installing your new roofing material.
Attach Your New Flat Roof Material
Once you’ve confirmed that your existing roof structure is sound, you can move on to applying your new flat roof material. This can be bought from a local supplier or online. Make sure to measure the length and width of your roof to match the material size; a roofing calculator can assist if needed. Before beginning, ensure the roof surface is clean and dry.
- Measure your roof and choose the appropriate size of roofing material.
- Position the folded material in the middle of the roof.
- Unfold the material to cover the roof’s width.
- Let the membrane rest for 30 minutes.
- Fold the material back over the right half of the roof.
- Apply adhesive on the left half until it becomes opaque.
- Quickly unroll the membrane onto the left side with adhesive.
- Press down on the applied membrane to eliminate air pockets.
- Apply adhesive to the right side of the roof.
- Unroll the remaining membrane over this side.
- Allow the adhesive to dry for 15 to 30 minutes.
Conclusion
While installing a flat roof might seem simpler than other roofing types, it’s not recommended as a do-it-yourself project. Attempting your repairs on your own can damage the roof and your home further. Additionally, you may invalidate your warranty and spend more than you would have by hiring a professional. Roofing is not a safe, economical, or easy task for DIY. For optimal results with your next flat roof installation, it’s best to take the help of a professional roof company. They will provide more guidance on roof replacements and installations for both commercial and residential roof services.
