Repairing a Leaky Flat Roof

A leaky roof is bothersome and annoying and you want to get it fixed as soon as possible. Before going ahead with your roof repair project have the following tools at hand: hammer, asphalt roof cement or compound, utility knife, propane torch with flame-spreader nozzle, security goggles, trowel, 6d galvanized roofing nails and clean rags.

The technique of fixing any roof varies, depending on what kind it is. Flat roofs are easier to repair compared to inclined or pitched roofs. Since it is flat you do not need to worry anymore on slipping or tripping which is great because you can concentrate on fixing the damaged spot of your roof.

The first thing you need to do is to find out where the leak is coming from. Usually leaks results from cracked and blistered roof surface. To help you fix your leaky roof follow these easy guides:

Flat roofs are composed of tiers of roofing felt and tar. Typically, leaks occur in an area exactly where roofing felt lasts to be broken making a deep spot. Leaks happen straight from these broken locations which may be observed fairly effortlessly.

Just briefly about Tar paper. According to Wikipedia, tar paper is "a heavy-duty paper used in construction. Tar paper is made by impregnating paper with tar producing a waterproof material useful for roof construction".

Roofing felt on the other hand is a "common type of tar paper, is a glass fiber or polyester fleece impregnated with bituminous material (tar, asphaltic bitumen); it is produced in roll form."

Tar paper is mainly utilized to waterproof roofs and to prevent moisture for coming or forming in. It is spread out before laying down the asphalt, wood, or other shingles down since tar paper is not completely sun or wind resistant.

Going back on fixing a flat leaky roof, typically on rainy days cracks or blisters holds water. Wipe the area dry with a clean rag. Remove dirt and paths of gravel. After which check where the melt or tar paper contains breaks or blisters.

To patch up or mend blistered roof surface:

Step 1: With a sharp knife, slice open the blistered surface until you reach its total depth. Be careful though not to touch the layer of roofing felt that is in good condition.

Step 2: Prop up the blistered layer. In the event that there is water underneath it, press down the edges to squeeze out water until you get every drop. Let it stay propped up until it completely dries out.

On wet season when layers are all soaked up, it is time to use a propane torch with flame-spreader nozzle to dry the area. Just be sure you have the protective goggles on. Use the flame over and over again until the layers have discharged out. Remember that roofing melt and tar paper are flammable so just be extra careful not to burn it, otherwise you need to buy a new layer.

However, when there is water on a wide surface underneath the blistered area then it becomes a complex problem that needs a professional roofer to do the job. The water build may be coming from between two inclined roof.

Step 3: Apply a generous quantity of roof cement underneath the edges of felt then set it down firmly. Tightly press across the corners with the blistered layer.

Final step: Completely secure all edges using 6d galvanized roofing nails then coat the entire blistered layer of felt with a dollop of cement to cover the nails heads.
