There are many different types of roofs, but if yours is of the flat variety, there are unique problems and repairs you may need to address. For example, flat roofs are prone to tears and bubbling in the roofing material. These issues can often be fixed without the aid of a professional roofer if you’re the handy type.
Flat roofs can be made from a few different types of materials. They can be smooth or granular and are slightly sloped to allow water to run off. Homes built in arid regions or urban areas may have large flat roofs, while many suburban homes have flat roof sections in addition to peaked roofs.
Minor Flat Roof Fixes
If the roofing material near a wall or around the chimney has begun to lift at the edges, you can use roofing cement to fill the void and create a seal. Be sure to apply plenty of cement to the area and smooth it well so water can flow freely.
If your roof has a small leak, you can often fix it quickly and easily by applying an aluminum fiber coating to the damaged area. This will stop the leak and extend the life of your roof. Unfortunately, this fix won’t work on gravel or mineral-surfaced roofs, though. To repair your flat roof, follow the steps below.
How to Repair a Flat Roof Yourself
Things You’ll Need
- Utility knife
- Roofing cement
- Fiber mesh patch
- EPDM or other flat roofing material
- Roofing nails
How to Do It
Step 1: Fill Damaged Area with Cement
Cut a slit in the bubble – you may need to cut a small strip of material away so the two sides can lie flat. Use the trowel to slide roofing cement underneath the roofing material.
Step 2: Cover with Cement
Cover the slit with a roofing cement to about six inches beyond the damage. Apply fiber mesh patch over the cement then apply another layer of cement.
Step 3: Cut Out the Damage
Cut a rectangle around the damaged area and remove the damaged piece. Use this piece as a guide to cut the patch.
Step 4: Spread Roofing Cement
Apply a layer of roofing cement in the cutout area making sure to get it underneath the surrounding roofing material. Place the patch you cut in the previous step into the wet cement.
Step 5: Cut Another Patch
Cut another patch that’s about six inches wider and longer than the previous patch. Spread another layer of roofing cement over the first patch and then place the second patch in the wet cement. Let it dry.
Step 6: Apply Aluminum Fiber Coating
When the roofing cement is dry, spread a layer of aluminum fiber coating to seal the area.
