In this article, you will learn useful roofing tips for finding and correcting leaks in all types of roofs, as well as some maintenance suggestions for gutters and ventilation pipes. Because working on a roof can be a dangerous proposition, be sure to follow the precautionary tips – they can only save you from serious injury or ask professional roofers in Montclair NJ.
Let’s start with a look at how to repair leaks on shingle roofs.
Roof repair safety tips
Working on a roof can be dangerous. Consider these safety precautions before proceeding with your roof repair:
- Roof repairs should be done on a sunny day when the roof is completely dry. Wet roof is slippery and very dangerous.
- Adequate safety measures must be taken for any roof repairs. Always use safety ropes.
- On steep roofs, use a ladder frame to ensure a secure anchorage.
- Rubber sole shoes provide the best traction when working on the roof.
- The position of the power lines must be taken into account when working on a roof.
How to fix loose gutters
If part of the downspout or gutter is loose, reconnect it to pop rivet using a pop rivet tool. Pop rivets can be installed from the outside, so you do not need to separate the downspout sections.
To install gutter pop rivets:
- Hold the loose section up in the correct position. Use an electric drill and pinch the size of the pop nails to drill through overlapping sections. Make a hole in each exposed side of the downspout.
- To adjust the pop rivet in each perforated hole, insert the rivet into the pop rivet tool, insert the tool tip into the hole and press the tool handles until the rivets come out. The pop rivets will keep the downspout section permanently.
From clogged gutters and loose shingles to concentrated water and flashing gaps, there are many types of problems that can cause your roof to leak. Do not let a roof leak cause water damage in your home. Use the tools in this article to help you quickly – and fix – the problem with relative ease.
How to repair roofing ventilation pipes
The appliance ventilation ducts and chimneys are sealed with metal flashing to prevent leaks, but the flashing may need to be replaced. Roof vents usually flash with a flat plate cut around the tube and a protective collar that fits at the base. Flashing for flat roofs usually covers the entire opening, with a flat base and a pipe housing sliding over the chimney. Replacing both types of flashing is fairly easy.
Make sure the flashing spare part is exactly the same type and diameter as the old one. Follow the roof safety procedures described below.
Caution: Wear work gloves when working with metal flashing because its blinking edges are sharp.
On a sloping roof, its flashing base is covered with pebbles on the side above the chimney and left exposed on the side below it.
To reposition a vent pipe on a pitched roof:
Step 1: Remove the pebbles from the roof above the chimney. Lift the shingles with the pry bar, but be careful not to damage them, as you will have to restore them to cover new flashes. If you break a pebble, you will need a new one to replace it.
Step 2: Remove it by flashing by inserting a pry bar blade under its edge and a lever bar on the wood waste block to lift the turn signal.
Step 3: Lift the vent pipe over the vent pipe, being careful not to knock the pipe out of place. Then pull the remaining nails around the pipe and fill holes with roofing cement.
Step 4: Adjust new flashes over the tube, with its protective collar aligned in the same way as the old one. Blink the nail with 6d galvanized ceiling nails and cover the nail heads with roof cement. Apply more roof cement on a protective collar sealing base.
Step 5: Put the pebbles behind the flash. Starting with the bottom row and working on the top, nail each pebble to its place at the top. Use two 6d galvanized roof nails for small pebbles, four nails for large ones. As you work, cover the nail heads with roofing cement. Slide the upper ends of the top row of pebbles under the overlapping lower ends of the above line.
To reposition a vent pipe on a flat roof:
Step 1: If there is gravel on the roof, wipe it off the vent pipe to clean the 4-foot surface.
Step 2: Locate the tip of the flashing base and use a sharp utility knife to cut slits from the roof canopy along one side.
Step 3: Insert the pry bar blade into the slot and below the flashing edge. Lever over blocks of wood chips, working along a slit in roofs, to release flashes. Cut the other three sides so that it flashes completely. Lift the old blinking out and over the tube.
Step 4: Adjust new flashes on the ceiling to determine how to fill the hole. For each layer of roof you can see in the hole, cut patch from a 15 kg roof with an auxiliary knife. Use the old flashing base as a pattern to cut the felt. On each piece of roofing bracket, mark the location of the vent pipe and the cutting hole at this point so that the patch fits snugly over the pipe.
Step 5: Apply a thick layer of roofing cement to the bottom of the hole, place the first patch on top of the pipe and press it firmly into the hole. Then apply more roofing cement on top. Fill the entire hole in this way, creating layers of felt and roof cement, until the top patch is level with the roof surface. Spread a thick layer of roofing cement over the top patch and fill any gaps around the vent pipe with more cement.
Step 6: Carefully adjust the new flare above the vent pipe and push it down firmly so that the vent tube is enclosed in the flashing tube and the base is aligned in exactly the same way as before.
Step 7: Blink the nail with 6d galvanized roof nails and cover the nail heads with roof cement. Using pliers, fold the top end of the housing tube down over the top end of the vent pipe to seal the new flashes.
Step 8: Blinking cover base with two more layers of felt – the first layer 3 inches larger and the second 6 inches larger than the blinking. As you did with the first patches, cut the hole in the center of each piece so that it fits over the vent pipe. Spread another thick layer of roofing cement over the flashing base, extending it 3 inches around the roof. Adjust a smaller piece of roofing felt over the pipe and press it into place. Cover this piece of felt with another layer of roofing cement, extending it again 3 inches into the roof all around. set the largest patch in place. Push this final patch down and nail it in place with 6d galvanized roof nails about 1 inch apart. Cover the nail heads with roofing cement.
Step 9: If you have removed the gravel from the patch area, you can apply it to a bare area, but this is not necessary.
