Step by Step Flat Roofing Guide
Get Rid of Your Old Roof
The first step to installing a flat roof that will replace an old roof is to remove the old roof. It should be stripped to the sheeting. Be careful not to damage any flashing trim or valley. Before you install your new roof, make sure to check for any damage. You can remove your roof by following these steps
- Remove any underlying roof by removing the fascia and gutters
- Use a spade to push into the layers of felts and fabrics.
- Grab the mortar-filled frame perimeter with your hand.
- Scrape any remaining surfaces with a hammer, bolster, or wallpaper scraper
- Take out the felt and any awkwardly positioned nails
- Remove any timber fillets with your spade or pry bar if you find them.
Assess for Damages and Repairs
Next, remove your old roof. Then you need to assess your roof for damage. If standing water is a problem, you should remove all roofing materials from the area. If the wood is fine, you can use roofing tar to rebuild that area before you apply your new roof material.
Attach Your Flat Roof Material (EPDM).
Once you have evaluated your existing roofing structure and determined that everything is in order, you can apply your flat roof material. Flat roofing materials can be purchased from any local retailer or online. To use your flat roofing material, measure the length, width, and size. This will match the size of the roof. A roofing calculator is a great tool to help you determine the size of your roof. Make sure your roof is dry and clean before you begin. Apply your new roofing material.
- Take measurements of your roof and choose the right roofing material
- Place the EPDM (folded material) in the middle of your roof.
- Spread the material along the length of the roof
- Let the membrane sit for 30 minutes
- Fold the material in half to the right side of your roof
- Adhere the left side of the roof to make it opaque.
- Roll the membrane quickly to the left side of your roof.
- To remove air, press the membrane into the adhesive.
- Adhere to the roof’s right half
- Remove the membrane remaining.
- Allow the adhesive to dry for 15-30 minutes
Apply adhesive to your flat roof. Make sure you cover all light spots until the surface becomes opaque. Before you apply adhesive to your flat roof, make sure that it is at least half dry before you start rolling the membrane. To test the adhesive’s wetness, you can touch it with your finger to check if it is tacky, but not stringy.
