Roof leaks can happen over the period, spotting and repairing it immediately is better than avoiding it further, which may lead to severe damage and Increase the repair costs.
If you have the expertise and the damage is very small, repairing by yourself would be better, but if you don't have the expertise, taking the help of a professional roofer is the better way forward.
Identify the Roof Leak
Before taking on any roof repairs, identify the exact spot where the leak is happening. It is commonly recognized easily by the naked eye by just taking a walk across the roof and searching for leaks. After a severe rainstorm, inspecting the shingles roof, spotting the damaged area, and making the repair plan are more relevant.
Finding the exact location of the leak is the foremost task in the leak diagnosis. Sometimes, it is visible to the naked eye. There are some common points in a roof that are more prone to leakage, such as roof valleys or roofing sections; besides this, you can inspect your home from the inside to spot water damage on the ceilings, wet spots, or dripping sound in severe cases.
Common Areas In Exterior Inspection
Roof leakage generally occurs in roof valleys and the areas where lots of dust and trash are collected. Flashing areas aligned to the apex of the roof, under the gutter and in space of dormer windows are the most vulnerable areas for roof leakage.
Inside Area in Interior Inspection
Sometimes the leakage can be seen within the interior of the house. The roof starts to leak at a certain point, and a few drops of water start flowing, especially during rain. The dampness on the interior walls is visible, requiring repairs.
Fixing Small Roof Leaks
Now that you have identified the leakage spot, an immediate solution is to fix it by yourself. Apply caulk around the area where the leakage is happening, repairing the damaged shingle and other surrounding shingles if needed to make sure it is tightly sealed. Repairing the missing or damaged flashing in the necessary areas. Last but not least, replace or repair the sheathing and underlayment.
Temporary Fixing of Leaked Roof
A plastic sheet or Tar is used as a temporary fix. Tar is a strong material that is weather-resistant and flexible, making it an ideal fixing material for immediate roof leakage. A temporary tar is placed over the damaged part.
Tar Paper
Measure the damaged roof part and cut the tar accordingly so it covers all the damaged areas. Proper stapling of the tar with galvanized staples and nails is carried out to ensure all corners and edges have been covered. Utilize a roofing adhesive around the edges of the boundary covered. Allow the adhesive to sit up and dry out before exposing normal weather conditions. Lastly, cover the Tar with layers of roof sealant.
Plastic Sheet
Using plastic sheets is much easier. Just cover the damaged area with the plastic sheets and put some weight on it, use nails into the wood wrapping and duct tape to install the temporary plastic cover over the damaged leaky roof part.
Roof Valley Leakage: Causes and Repairs
Nails
Causes
When nails are installed too close to the center of the valley, it can cause the area to leak, as the majority of the water flows in the center of the valley. Sometimes, a missing nail can also be the cause of leakage as the hole drilled for that missing nail can let the water in the roof cause leakage.
Repairs
Placing the nails ten inches out of the center of the roof valley ensures there isn't any damage due to nail installation. Still, if there is a doubt, roofing cement can be used to cover any holes or gaps created by the nails.
Underlayment
Causes
This occurs when the underlayment isn't installed under the shingles. A waterproof sheet that can handle water and ice is laid under the shingles roof to make the roof leak proof. Any openings left unattended in this underlayment lead to leakage.
Repairs
While installing the roof, check the underlayment by spraying water using a garden hose on your newly installed roof to detect any leakage. If there is a leakage, remove the shingles from any side, install the underlayment, and cover it with new shingles. Use roofing cement to cover any holes and gaps.
Shingle Corners
Causes
The leakage occurs when the corners of the shingles aren't properly horned with each other. The gap leads to roof leakage and might require immediate attention.
Repairs
Separating the overlapping shingles in the roof valley does the trick to fix it. After separation, cut the corner and fill the gaps by roofing cement to secure any gaps. This ensures water doesn't run sideways, damaging your structure walls for a longer period of time.
Metal Roof Restoration Process
Leakage at metal roofs is more complex compared to shingle roof valley repairs.
Causes
-
Improper Installation- If the roof panels aren’t installed properly, they can get damaged in the strong wind opening a passage for the water to go in.
-
Faulty Fasteners- If the screw installation is wrong such as it can be under-driven, over- driven, or installed at the wrong angle can leave openings in the roof, causing leakage over time. Failing gaskets or screws can also be an issue.
-
Missing or failed flashings- Flashings are used to seal the edges and other such areas where the roof covering ends. If the flashing isn’t installed properly around the vulnerable areas, your roof will leak.
-
Rust- If your roof stays rusty for an elongated period and you neglect its repair, it will get highly damaged over time, leading to a leak.
Repairs
-
Cleaning- Identify the leakage spot and then clean the damaged area using a household cleaner, and give it some time to dry out.
-
Marking and Buffing- Mark the damaged leak spot with a pencil and buff the damaged part with steel wool. The buffing process ensures better bonding when the sealant is applied.
-
Cutting and Sealing- Cut the patch from the replacement metal panel as per the measure. Sealant is applied evenly to the damaged area. Place the cut metal patch above the sealant and press it hard in a manner that sealant oozes out from all sides of the patch.
-
Secure and Color- Secure the patch with screws, and use the sealant to save the edges. Remove any extra sealant and color the repaired patch as per the overall roof color.
Affix Roll Roofing
Look out for cracks by inspecting the roll roof. Watching through, you come across some kind of blister or bubble; it is a sign of a leak that has been incurred in the roll roofing material. Any small damage can be quickly repaired by applying a roofing sealant. The wider gap would require patching up work to secure it. Calling a professional roofer to do the wider leakage is a better option.
Repairs
-
Cut and Clear- Cut the blister or bubble part, and clear any dust and gravel from the area.
-
Soak and Dry- Soak the water out from the blisters and leave it to dry for a day; if in a hurry, use a dry rag or blow dryer to make sure it is totally dry out before commencing further repair work.
-
Spreading Roofing Cement- Spread evenly the cement from every corner and edge of the damaged part and nail it up.
-
Use of Fiberboard- Check for holes and gaps beneath the rubber. Use the cut piece that has been dried out for repairs. Buy a fiberboard and use it wherever patching is required as a substrate material while fixing the roof.
-
Fastening the Roll- Once the substrate is installed, affix the rubber roll by applying the roofing cement. Check the edges and perimeter; if there are any gaps, spread a cement layer again to fill them.
Gutter Downpour: Issues and Solutions
The interior wall dampness is caused by the gutter pipes that clear water from the roof. These gutter pipes are generally installed on the outside wall of the house, from the roof to the bottom. When the leaks happen in the gutter, the moisture and dampness show up in house walls. Proper leveling of gutter fasteners so that their downslope is away from the house makes sure the leak is stopped.
Positioning
Poor positioning of the gutters is the real cause of the leaks. The downpour should be placed at least six inches from the corners of the roof to the walls, ensuring any heavy downpours don't damage the interior of the walls.
Aluminum Fascia
Aluminum fascia is installed at the gutter drip edge for fastening the rainwater downpour. Any lacking in these fascia causes leaks in the gutter pipes, leading to dampness. Repairing or reinstalling the aluminum fascia minimizes the water leakage damage.
Safety Precautions while repairing a roof yourself
Working out on the roofs is dangerous work, and it is appropriate to take proper precautions before undertaking any repair work.
Sunny Days
Never work in wet conditions. Roof repair work should be undertaken on hot sunny days.
Safety Harness
Use safety ropes and harnesses while working on the roofs.
Ladder Usage
Use ladders wherever possible, as they are much safer than working on the ropes.
Rubber Shoes
Rubber shoes are to be worn whenever working on the roof. Wearing them not only safeguards from any slippage but also from any electrical current.
Power Lines
The height of power lines should be kept in mind while working on roofs.
Repair Vs. Replacement
Whether to go for repairs or replace the whole roof is the dilemma that house owners need to decide upon.
Warranty
If you have the ongoing roof warranty then the repair or replacement would be taken care of in the warranty.
Frequent Repairs
If the roof is leaking every year, even after continuous repairs, then it is time to think about replacing it completely.
Life- Expectancy
The roof has lived its life term; for instance, the roof life is 20 years, and if it has completed more than twenty years, then it is time to replace it.
Weather Conditions
Repairs should be taken before rain and snowfall and any damage should be inspected after the rainy and snowing season. If the repair work costs more than the new roof replacement, it is better to replace it.
Individual Option
Generally, roof repairs are less expensive than the replacement; deciding upon remains an individual option while keeping the work and cost efficiency of repairs against replacement.
Conclusion
The key to resolving the roof leakage issue is a yearly or half-yearly roof inspection, to be carried out by a professional or by yourself. Small repair work can be undertaken by yourself, but for wider and vast repair, a professional roofer is needed.
