How Much Does It Cost To Repair A Skylight?

We love skylights. Also known as roof windows, they are valuable aesthetic elements and practical means to bring more natural light into the home. Above all, skylights offer fantastic views of the outdoors.

Unfortunately, like the rest of the roof, skylights can break and leak. Indeed, they are the weakest part of the roof. Thus, they are the most likely to break in case of a storm or falling tree, necessitating immediate repairs.

Therefore, we’ve developed this guide to help you understand skylight repair costs so you are well-prepared if your roof window starts leaking.

How much does it cost to repair a skylight?

The average cost to repair a leaking skylight is $892. However, the actual cost ranges from $420 to $1,365, depending on multiple factors, including the type of skylight, the severity of the damage, and accessibility. Meanwhile, total skylight replacement costs $500 to $2,000, depending mainly on the type and size of the skylight.

Why is My Skylight Leaking?

The four main causes of skylight leaks are poor installation, low-quality materials, natural failure, and external damage;

Poor installation:Skylights comprise multiple parts that work harmoniously to illuminate your home and provide beautiful views. However, poor installation can cause premature failure of various parts, such as sealing or flashing. When these parts fail, the whole skylight fails.
Low-quality materials: Inferior skylight materials will likely fail immediately or within a few months. For instance, some roofers still lay skylights over asphalt paper, which breaks down within one or two years. Instead, use an ice-and-water shield which is more durable.
Natural failures:The components making up a skylight can also fail naturally due to age or wear and tear. For instance, the glass pane begins to yellow and discolor after 8-15 years. When this happens, it’s time to replace the skylight.
Weather and accidents:Finally, skylights can break due to adverse weather and accidents. For instance, falling tree branches and hurling stones at the roof can break the skylight. Similarly, strong winds and storms can uproot the skylight.

Factors Affecting Skylight Repair Costs

Multiple factors affect the cost of repairing skylights, from the type of skylight to accessibility and roof pitch.

Skylight Type

There are three main types of skylights. The cheapest are tubular skylights, which take up the least space on the roof and don’t need much installation work.

Tubular skylight repair costs range from $300 to $500. Next, fixed skylight repairs cost $400 to $900, as they are bigger.

Finally, ventilating roof windows are more complex and thus more expensive to repair. Ventilating window repairs cost $500 to $1,200 on average.

Glass Type (Glazing Material)

Different skylights are constructed from different glazing materials. These include acrylic, tempered glass, and double-pane glasses.

Acrylic glazing ($150 to $1,000) is the cheapest to repair or replace, followed by tempered glass ($200 to $1,500). Double-pane glass skylights ($300 to $3,500) are the costliest to repair or replace.

Size

Skylight sizes vary, from small 25 x 25-inch units to extra-large 33 x 57-inch panels. So, as you can expect, it costs more to repair a larger skylight. Replacement costs also depend on size.

For instance, a 25 x 25-inch skylight costs $150 to $1,000 to repair or replace, while a 33 x 57-inch skylight costs $500 to $2,000 to repair or replace.

Accessibility

Repair costs also depend on how easily the technician can access the skylight. For instance, higher skylights are more difficult to access. Similarly, tubs or other obstructions make the technician’s work more complicated.

Finally, the charges also depend on whether the technician needs to access the skylight inside and outside the house. So, expect a 30% higher repair cost depending on the accessibility challenges.

Roof Pitch

Most skylights are designed for roof pitches between 15% and 60%. Unfortunately, installing roof windows on steeper roofs is more dangerous, requiring extra scaffolding.

Moreover, the installer must use special flashing to prevent roof leaks. The result is usually 20% higher repair costs.

Roof Modification

Finally, does the roof require modifications? For instance, sometimes, skylight leaks result from gaps between the roof window and the roofing panels.

Therefore, you may be charged more if the repairs involve replacing the surrounding shingles/panels. Similarly, you may pay more for roof cleaning around the skylight panel.

Leaky Skylight Repair Costs by Problem

Primarily skylight repairs are priced based on the type of problem. The following are common skylight issues and typical repair costs;

Leaking Skylight Repair Costs

Standard skylight leaks cost $50 to $600 to repair, depending on the cause of the leak. The most common causes of leaky skylights are loose flashing between the framing and the roof and broken seal between the framing and glass pane. Fortunately, repairing or replacing the flashing or seal is easy.

Heat Loss Skylight Repair Costs

Fixing skylight heat loss issues costs $50 to $800, depending on the root cause and solution. For instance, most heat loss complaints arise from broken seals between the frame and the glass pane.

Mold-Infested Skylight Repair Prices

Fixing mold-infested skylights costs $50 to $1,700, depending on several factors, including the root cause and whether a replacement skylight is needed. For instance, clearing mild mold issues on the glass pane is quick, easy, and inexpensive.

However, fixing moisture or water issues causing the mold is more complex and typically costs several hundred.

Cracked-Skylight Repair Cost

It costs $300 to $1,700 to repair a cracked skylight. The biggest issue is whether repairing the cracked glass panel is worthwhile. Often, it isn’t.

Nevertheless, the contractor can temporarily seal the panel with silicone caulking and patch it up with weather tape until you find a permanent solution. Cracked frames are slightly more affordable to repair or replace.

Cost to Repair Skylight with an Ice Dam

Finally, skylight ice-damming repairs cost $400 to $1,200. The exact costs depend on the time it takes to clear up the damming issue and whether additional repairs are needed to restore the skylight.

For instance, proper attic insulation and ventilation are critical to long-term ice dam prevention – both expensive projects.

Leaky Skylights Repair Costs by Solution

What repairs are needed to eliminate the issue and restore the skylight’s beauty and function? The following are the average estimates.

Skylight Flashing Repair Costs

Skylight flashing repairs cost $50 to $150, on average. Minor repairs merely involve sealing holes or gaps in the flashing using roof cement.

Most contractors use regular caulking and roofers’ tape to patch the section. More advanced repairs involve specialized foam.

Unfortunately, you need a total flashing replacement if the skylight leaks water. Flashing replacement costs at least $150.

Skylight Seal Repair Costs

Skylight seals cost $50 to $200 to repair. Common repairs include re-sealing the broken or corroded section. Fortunately, the sealing fails gradually rather than abruptly. So, it’s easy to catch minor issues before they become big problems.

Major issues require replacing the existing seal. Nevertheless, $200 is enough for sealing replacement in most states.

Skylight Motor Repair Costs

Skylight motor repairs cost $50 to $500. Replacing drained batteries is the cheapest solution, costing $50 or less in most cases. Total motor replacement costs up to $500.

In between, you may need rewiring if the motor’s electrical system malfunctions. Similarly, you may need to replace failed components. Otherwise, the skylight may become difficult to open or close.

Skylight Frame Repair Costs

Repairing skylight frames costs $150 to $600. The exact cost depends on the size of the skylight and the framing material. Corrosion is the most common cause of damage.

First, constant water and weather exposure causes corrosion, weakening the frame. Then the frame cracks, chips away, and breaks.

Skylight Dome Repair Costs

Finally, standard skylight dome repair costs $100 to $200. Cracks and leaks are the most common issues. They damage the surrounding roof shingles and potentially the attic and ceiling below.

Sealing with silicone caulking is enough to fix minor leaks and cracks and rarely costs more than $200. However, a replacement is necessary if the dome is badly damaged.

Skylight Parts Replacement Costs

So, we’ve mentioned “replacement” severally. But how much does it cost to make various skylight parts replacements? The following is a helpful cost breakdown;

Skylight Glass Replacement Cost

The cost to replace skylight glass is $150 to $600, depending on the type and size of the glass. Acrylic glazing is the cheapest to replace, typically costing about $150.

Tempered glass glazing cost at least $200 to replace. Finally, it costs $300+ to replace double-pane glass glazing.

Skylight Dome Replacement Costs

Skylight dome replacement costs $350 to $900. Again, the dome properties are the primary cost factors. First, dome skylights vary in size. Additionally, the domes vary in material and aesthetics. Larger domes cost more to replace, while smaller ones cost less.

Skylight Flashing Replacement Cost

Skylight flashing replacement costs $300 to $500. A skylight flashing kit alone costs $20 to $400. Then you can expect labor charges starting from $150, depending on the project’s difficulty. However, a full re-flashing often points to a major issue. So, consider full skylight replacement.

Skylight Seal Replacement Costs

It costs at least $200 to replace the skylight’s seal. However, it’s a critical maintenance practice that prevents leaks around the skylight.

One of the reasons it’s expensive is that skylight seal inspections are conducted from outside. Then re-sealing happens inside and outside for a waterproof seal. Only re-seal if your skylight is relatively new and hasn’t cracked or yellowed.

Skylight Frame Replacement Costs

Skylight frame replacement costs $150 to $2,500, depending on various factors, from frame type to size. Vinyl frames are the least expensive to replace, costing $150 to $1,500.

Metal frames, which are more durable than vinyl-framed skylights, cost $200 to $400 to replace. Finally, wood frames are the most expensive to replace. Replacing a wooden skylight frame costs $300 to $2,500

Skylight Repair Labor Costs

Skylight repair labor charges range from $50 to $100 per hour. However, most jobs only take 1-2 hours. So, you shouldn’t expect a big labor bill. Typically, handymen and roofing contractors perform the repairs.

The labor costs are higher if you hire a maintenance specialist for a professional inspection. An inspection costs $100 to $600 and is included in the final bill.

Most companies charge flexible rates that vary depending on the complexity of the job and skylight accessibility. For instance, fixed skylights are cheaper to repair than vented skylight models.

Emergency Skylight Repairs Cost

Emergency skylight repair costs range from $100 to $300 on top of standard labor charges. For instance, whereas a regular heat loss repair job costs $50 to $800, emergency jobs cost $350 to $1,100.

However, the costs are worth it, given the potential savings. For instance, severe leaks can cause severe damage in the attic and down on the floor. In addition, rotting, wall damage, and water damage are possible. The leaks can also short-circuit electronics and damage your stationery.

Emergency repairs typically happen on weekends and public holidays. Some also start earlier than usual or go way into the night.

Skylight Replacement Cost

Total skylight replacement costs range from $900 to $2,500, though it costs way more to replace certain skylight models and brands.

For instance, replacing a VELUX skylight costs $900 to $3,600. Fixed models are the cheapest to replace, costing $900 to $2,400. Meanwhile, manual “fresh air” VELUX skylights cost $1,200 to $2,700 to replace, and ventilated models $2,000 to $3,600.

The replacement process involves removing the existing skylight and replacing the entire skylight with a new one while ensuring a secure and weatherproof seal and flashing.

Removing a skylight costs $125 to $250 on average, while removing a skylight over an opening costs $350 to $1,000.

Skylight Repairs: DIY or Roofing Contractor?

Given the costs of professional repair, you may suddenly feel you could save significantly by going the DIY route. But is it worth it? Let’s find out.

DIY Skylight Repair Pros and Cons

The main advantage of DIY skylight repairs is cost savings. You can save about 50% of total professional costs for most projects. For example, many professional roofers demand $600+ for a skylight leak repair. Instead, you can do it yourself for under $300.

Meanwhile, the biggest downside is the risk of falls. At least 111 people die every year from roof falls. So, you must be careful. Other pros and cons of DIY slight repairs are;

Pros

No queues, no waiting
It’s a fun activity

Cons

It’s labor-intensive
You may cause additional roof damages

Pros and Cons of Hiring a Skylight Repair Contractor

Quality is the main advantage of hiring a professional roofing contractor for skylight leaks. They guarantee quality services and typically provide warranties to protect their work.

Unfortunately, professional skylight repair can be expensive. Additional pros and cons of professional skylight repairs are;

Pros

Professionals can uncover additional roof issues
It frees you from labor and safety risks

Cons

You must queue for your turn

Other Factors Affecting Skylight Repair and Replacement Costs

We’ve already seen the main factors affecting the average price of skylight repairs and replacement. However, that was only part of the list.

Other factors that determine the final bill include;

Warranty

Most skylight units carry manufacturer and roofing contractor warranties. So, you want to check with the manufacturer and roofer before scheduling a repair.

For instance, top-end VELUX skylights carry an industry-first 20-year glass pane warranty and a 10-year no-leak installation warranty.

Home Insurance Coverage

Standard home insurance policies cover skylights against unforeseen and natural damages. For instance, your policy likely covers the cost to purchase and professionally replace your skylight if it’s blown away by a powerful storm. So, again check with your policy carrier before scheduling repairs.

Is it a Mobile Home?

Mobile home skylight repairs cost $250 to $700, on average. The exact bill depends on the skylight’s size and the mobile home’s location.

For example, you’ll pay more if the contractor travels several miles through rough terrain to access the mobile home.

Condensation Issues

Fixing skylight condensation issues costs $50 to $700. Typical repairs include replacing the seal or flashing. Alternatively, you may need to change the frame.

Permits

The skylight forms part of the roof. Therefore, you may need a permit to repair or replace it. The good news is that some states don’t require a permit for minor roof repairs.

But, unfortunately, you can only know if you find out from the authorities. So, check with your local building department. Where applicable, reroofing permits cost $50 to $250 for repairs and $150 to $500 for replacements.

Taxes and Rebates

Homeowners can claim a 30% tax credit for replacing old skylights with modern, energy-efficient models under the Residential Clean Energy Credit.

For instance, manual and ventilated VELUX “fresh air” skylights qualify for 30% tax credits. Wasco E-Class and G-Series skylights also qualify.

Tips to Prevent Skylight Leaks

A few prevention tips can extend the life of your skylights, saving you costly repairs and premature replacements. Consider the following;

Regular maintenance and inspections
Boost the sealing during regular maintenance
Ensure proper ventilation inside the home

Leaking Skylight Repair Cost FAQs

Can Leaking Skylights be Repaired?

Yes, you can replace leaky skylights. This is especially true if the leak originates from where the skylight meets the roof. Replacing or repairing the flashing fixes the leaks. Unfortunately, repairing cracked, leaky skylight glazing is difficult. Replacement is the only solution in this case.

Is it Common for Skylights to Leak?

Yes, it’s not unusual for skylights to leak. For example, deck-mounted skylights are prone to leaks because they flash against the roof surface. On the other hand, curb-mounted skylights come with flushing and are counter-flushed to the surface, reducing the risk of leaks.

Where do Skylights Usually Leak?

Skylights mostly leak around the sealant, flashing, and old roofing material. Additionally, a crack in the skylight almost always causes a leak through the glazing. Unfortunately, it can be difficult to pinpoint the source of the leak. So, it’s best to get a professional inspection.

Do Skylights Need to be Re-Sealed?

No. You don’t need to re-seal skylights as the original seal typically lasts the life of the skylight (10-15 years, on average). However, don’t hesitate to re-seal it if the seal is broken or leaking. You can do it yourself or hire a professional for $50 to $200.

Who do you Call to Fix a Skylight?

It’s best to call a roofing contractor if you have a skylight leak. They are the best place to diagnose the issue, determine the root cause, and provide a lasting solution. However, consider a handyperson if you feel a professional roofing contractor is too expensive.

How often should I Replace a Skylight?

We recommend replacing skylights every 15-20 years. Unfortunately, the structures lose their cutting edge after 20 years, often appearing yellowish or having a cloudy view. Cracks and leaks are also common, increasing maintenance costs. It’s more cost-effective to replace the skylight at this point.

Should I Replace Skylights when Reroofing?

Yes, it would help if you replaced the skylight when installing a new roof. First, it’s cost-effective. The roofer will bundle the shingle and skylight installation costs without extra bills.

Secondly, doing so allows you to synchronize the roof and skylight for the perfect roof infrastructure and curb appeal. Also, you can take advantage of full-roof warranties and new features, technologies, and coatings.

Summary

The cost to repair a skylight ranges from $420 to $1,365, with homeowners paying $892 on average. However, the exact costs can be as little as $50 and as high as $3,200, depending on the type of skylight, accessibility, the type of repairs, and the need for repairs or parts replacements.
