Skylights are also a common trend in most households as they are known to welcome the natural light, create an open space feel and make the space look bigger and friendly. Nevertheless, they are so pretty, skylights are known to have one annoying problem, one leakage. A leaking skylight is not always a small nuisance as it may cause stains, mold, rot in wood, and even damages in the building unless there is a quick action to solve the problem.
The positive news is that skylight leakages can be resolved with limited replacement of the whole window. In the correct treatment, you will be able to find out the issue, implement the appropriate fix and have your skylight operating well over several years. You will be taken through all that you need to know: causes, warning signs, tools, repair methods, preventive maintenance and when it is best to call in a professional from Northwest Roof Maintenance Inc in Vancouver WA. So, how to fix skylight leak?
Understanding Skylight Leaks
You should also know the reason why skylights leak before you take your ladder and sealant. A skylight means a window fitted on the roof. That is to say it is continuously exposed to the sun, rain, wind and also changing temperatures. This is unlike vertical windows where the skylights are at an angle such that water naturally flows towards such a direction and thus on them the skylight is prone to leaks.
Common Causes of Skylight Leaks
- Weather Damage: Harsh weather is among the topmost culpable of skylight woes. Small and loose seals can be played with by heavy rain, snow can build up and occur around the skylight where the water melts away and the wind can blow off shingles or flashing which restricts water entry. In the long run, sealants also dry out and crack as a result of UV radiations.
- Aging Materials: The skylight gaskets, flashing and sealants are used to enclose and deteriorate as they age. Having attended to the skylights, after 10-15 years, they tend to leak small amounts of water in case they were not taken care of.
- Poor Installation: The skylight only goes as well as it is installed. Without the proper installation of the flashing, the levelness of the frame, and even the correct overlapping of the roofing shingles, then it is almost certain that leaks will occur.
- Roof Problems: Sometimes the skylight is not the problem. Broken shingles, stooped gutters or lack of proper roof drainage may direct water to the skylight and it will somehow access the inside.
Symptoms of a Leaking Skylight
Early identification of a leak in a skylight can save the necessary expensive repairs. The following are some obvious indicators:
- Stains or discoloration of the surrounding of the skylight frame or ceiling with water.
- Leakage of water during precipitation.
- Growing molds or mildews on surrounding walls.
- Blistering or sagging plaster around the skylight.
- Extrusion or moisture builds up in the glass unit.
Once you see any of these signs, it is always better to act as early as possible before the problem gets out of hand.
Planning to Fix Skylight Leaks
After making sure that you have a leak, the next thing to prepare is to prepare. There is nothing worse than trying to repair a skylight without equipment or safety measures and end up injuring yourself.
- Gathered Materials and Supplies.
- Extension ladder that is high enough to reach your roof.
- Non-slip shoes, goggles and safety gloves.
- Caulking gun and exterior grade roof sealant.
- Patent cement to apply to cracks.
- Flashing tape or waterproof membrane.
- Flat pry bar and hammer removing shingles.
- Replacement flashing kit (where necessary)
- Utility knife and roofing nails.
- Replacement/components (in extreme cases) of skylight or components.
Safety Precautions
The process of roof repair is always risky and, therefore, the safety factor plays a crucial role:
- Work only on a dry day. The wet roof is very slippery.
- Plant your ladder on a level structure and have somebody hold the ladder stable.
- Wear shoes that are good grippers.
- Do not strain too far–you must keep your body over the ladder or roof.
- High roofs or skylights that are very high above ground are situations where professional work should be called in, rather than do it oneself.
Step 1: Identifying the Source of the Leak
It is sometimes a bit difficult to isolate the point of leakage. Water does not always move straight, sometimes it enters by flashing, it may run along the beam, and be several feet off the leak itself.
Exterior Inspection
Get on top of your roof (safely) and have a good look around the skylight:
- Identify broken, absent, curling shingles.
- Check the flashing on the skylight, rust, holes or pebbles.
- Look to see whether nails or screws are loose or missing.
- Clean up the leaves or debris that can be holding water.
Interior Inspection
Within your house, check on the indicators of water intrusion:
- Ceilings and walls around the skylight are discoloured or stained.
- Damp insulation in the attic
- However, distorted wood or plasterboard around the frame.
- Smells of moulds that represent the presence of moisture.
In case of your doubts, do a hose test. Ask somebody to spray water around the skylight as you look inside the house to know where the leak is leaking.
Step 2: Interim Solutions on the Skylight Leaks
When you are about to be hit by bad weather and you do not have time to have a full repair there is always a temporary repair that can reduce damage.
Roofing Cement or Caulk
Apply roofing cement or exterior caulk (using caulking gun) to any small cracks in flashing or seals holes. This will prevent water up until a permanent repair.
Flashing Tape
Use flashing waterproofing tape on small gaps. It sticks directly on metal and shingles to create a temporary shield.
Emergency Covering
In case the leak is severe, the skylight should be covered with a waterproof tarp or plastic sheet that is tied down with wood strips or heavy objects.
There should be measures that are seen as stop-gaps. To overcome the problem completely, there is always the need to solve it through long-term solutions.
Step 3: Permanent Skylight Leak Repairs
Now I will proceed to the long-term solutions that will adequately deal with your skylight leak.
Resealing the Skylight
- Removal of old, scratched caulking on the skylight frame.
- Wipe off the surface to have good adhesion.
- Use a new bead of exterior grade caulk around all edges.
- Apply with a putty knife to make a continuous seal.
This is normally sufficient when it comes to minor leakages due to damaged sealant.
Fixing or Reforming Flashing.
Flashing refers to the metal sheet that is thin and it covers the skylight to push away water. One of the most widespread culprits of leaks is damaged flashing.
- Shingles on the skylight will be removed with a flat pry bar carefully.
- removing the old or broken-off flashing.
- Install new flashing, ensuring that it overlaps properly to be drained out.
- Nail and roofing cement nail heads.
- Install shingles again and cover up any open ends.
- The Skylight Components are to be replaced.
- Replace them with new ones in case they are cracked or brittle.
- When the skylight is cracked, it might be required to replace the glass or dome.
- In case the skylight is old (15 years or more) and continues to leak despite the patching, it can be replaced, which could be cheaper than patching.
Step 4: Preventive Maintenance to Avoid Future Leaks
Replacing a leak in a skylight is one thing, and avoiding the subsequent ones is another. The frequent maintenance will assist in prolonging the life of your skylight and roof.
Constant Cleaning and Inspections
- Eliminate leaves, branches and dirt surrounding the skylight.
- Check on flashing and seals at least once in six months.
- Look at your attic after heavy rain and see whether there is any initial sign of leaks.
Roof Maintenance
- Use shingles to substitute lost or broken shingles.
- Gutters and downspouts should be kept free of debris to avoid overflow of water.
- Prune the trees that fall over your roof.
Professional Inspections
This is even though you may be hardworking, certain issues cannot be seen by the ordinary person. Professional inspection of the roof should be scheduled 1-2 times every year at which point, the minor problems would be identified early before evolving into big leaks.
When to Call a Professional
Although a large number of the leaks in skylights can be patched using self-help techniques, there are cases when expert help is necessary:
- Your skylight is a steep roof or multi-story.
- In flashing repair, a lot of shingle removal is necessary.
- The glass on the skylight is broken or the frame is distorted.
- The water damage has extended into insulation, framing or drywall.
A professional roofer is not only going to repair the existing leakage but also make sure that your skylight is sealed so that you do not have such a problem in the future.
Skylight Repair Leak Costs
Knowledge of repair cost will assist you in budgeting:
- DIY Repairs: Sealant, cement and flashing tape cost between $50-200.
- Professional Resealing or Flashing Repair: $300 to 800, depending on the complexity.
- Replacement of Skylight: Between 900 and 2,500 involves labor, size, and style of the skylight.
Although DIY can cost less, professional repair can have more long-lasting benefits and cost less in case of water damage in the future.
Conclusion
A skylight will change your living space, turning it into a more inviting one. However, in case of leakages, they could easily become a masterpiece into an expensive nightmare. Hope so, now you know how to fix skylight leak?
The key is to act fast.
