Skylight Leak Repair Flat Roofs

Skylight Leak Repair Specialist

We have been repairing leaky skylights over 30 years

Skylight Leak repair

Leaky Skylights

There are many brands, sizes, and shapes of skylights. There are many reasons for a skylight to leak. The two most common place for the leaks to occur is between the frame and the glass and also the flashing.

Every brand has its way of being repaired. Some skylights have a flat glass surface, and some have a domed plexiglass surface.

Troubleshooting what causes the leak on the skylight is the hard part. It is never evident. The glass must be separated from the frame to be able to replace the gasket. This leak repair is tedious and costly.

Glass skylights leak repair

Glass skylights are harder to make a leak repair on. There is a gasket between the metal frame and the glass of the skylight. The frame is factory assembled and sometimes not possible to be removed. Many times the cost of repairing a leaky skylight outways the cost of installing a new one. The gasket is not replaceable and therefore a new skylight must be installed.

Glass Skylight leak repair flashing

The other area where it can leak is on the flashing. When the rubber membrane separates from the flashing water can leak in. This type of leak repair on a skylight is relatively easy and not too costly.

Any roofing contractor that is familiar with that particular roofing system can make a repair.

Plexiglass Dome Skylights

Plexiglass dome skylights will crack over time causing leaks. The best way to make a leak repair is to replace the top part of the skylight. Some brands allow you to replace the plexiglass by itself. Skylight leak repairs are possible in some case when there is a gasket between the dome and the frame.

Modified Bitumen Torch Down Rubber Roof Leak Repairs.

We specialize in Modified Rubber Roofing system. Roof leak repairs are seldom necessary because the material is thick and tough and therefore won’t puncture. Some repairs are necessary due to incorrect flashing attachment or seams that were not welded properly.

Leak Repairs on an EPDM Rubber Roof

The seams on an EPDM Rubber Roofs will often separate due to the adhesive failure. Repairing leaks in these rubber roof are common.Roof leak repair is not easy on an EPDM roof because it is hard to detect what causes the leak. We have made 1000’s of roof leak repairs on EPDM rubber roofs. In its forty years of existence, the adhesives have been the main culprit of causing roof leaks. The best way to repair the seams on these EPDM Rubber Roofs is to install a cover tape over every seam.

The other reason why so many repairs are needed is that the caulking used to cover the edge of every seam dries out and shrink making a small void area where two overlapping seams meet. To make a leak repair, in this case, all the caulking has to be removed, and a new beat of caulking applied.

Petroleum based lap sealer is used to make these leak repairs.


Leak Repairs on a TPO Vinyl Roof

TPO roofing requires a heat gun to fuse the seams together. Sometimes when this heat is applied, weather conditions change causing the gun not to apply the proper heat to the seam for melting. This seam can separate and cause a roof leak. To find the leaky area a sharp probe is used against the seam to find a separation or weak spot. After identifying this weak area, a patch is installed with a heat gun. Leak repairs on TPO roofs are not easily done and can be costly.

Repairing Roof Leaks

We have been in the Roof Leak Repair business for over 30 years. The challenge is not repairing the leak, but rather finding the cause of it. Troubleshooting a leak on a roof is the hard part, repairing it is the easy part.

We started as The Flat Roof Doctor in Norwalk, Connecticut, repairing leaky roofs. Our experience of over 30 years helps us to find leaks and make the necessary repairs quickly.

Repairs on Flat Roofs

Repairing leaks on a flat roof is easy, finding it is often the problem

We Repair Modified Bitumen Torch Down Rubber Roofs

We specialize in the repair of Modified Bitumen Rubber Roofs. As long as the rubber roof is in a relatively good condition, we can find the leaks and make the necessary repairs. Most leaks are due to the membrane pulling away from the flashing. We developed a special technique making repairs on flashing and metal edging where this membrane is attached too. For the most part, to make such a repair, we need to cut the membrane away from all flashing and drip edges and install a new strip attaching it to the metal and the old roof.

Once we have repaired Modified Bitumen Torch Down Roof, we provide a new warranty on the work that was done.

Repairing an EPDM Roof

EPDM Roofs are notorious for leaks. Repairs are necessary due to the failure of the adhesives that were used to glue the seam together. With the installation of an EPDM Rubber Roof, adhesives are used to stick the seams, flashing and other objects to the rubber together. Theses adhesives fail prematurely and cause leaks. We repair more EPDM Rubber Roofs than any other roof system.

When an EPDM Rubber is separating from metal, it is best to cut the rubber away and install a new section. Repairs are harder to make where metal flashing or drip edges are.

When EPDM Rubber seams are failing, EPDM cover tape is then used to cover the seams. These repairs often extend the life of the roof for about five years.

Skylight Repairs

We repair skylights. Leaks on skylights can come from two places. It could be the seal between the frame and the glass is broken or the flashing around the skylight is leaking. Repairing skylights properly takes an exceptional understanding and experience. There are many types and brands, and each of them is repaired differently.

We have been repairing skylights for over 30 years.

Repairing Drains on a Flat Roof

We have been repairing drains since we started the business 30 years ago. For the most part, to repair a drain, all the existing roofing material must be removed and, and the drain’s metal flange must be clean.

After removing all the tar and roofing materials, then a new membrane is installed attaching the roof drain to the roof again.

Often, the repairs include lowering the drain to allow water to flow better off the roof.

Repairing leaks around vent pipes

We often have to repair the flashing around vent pipes on a roof. The roof membrane attached to the vent separates and causes leaks. We repair it by installing new flashing.

Repairing Scuppers on a flat roof

Very often a scupper will cause a leak and a repair is needed. We will remove all the roofing material that’s around and on the supper and make a proper repair. Once we have repaired a scupper, the water will flow better off the roof.

We specialize in the Installation of a Two-Ply Rubber Roofing System. This system comprises of 2 layers of Modified Bitumen Torch Down Rubber Membranes that are fused together. By adding a second layer, it makes this type of roofing superior to any other roofing system.

The Two Ply Modified Bitumen Torch Down Rubber membrane is a superior roofing system than that of a Single Ply EPDM or TPO Roofing System. This roofing system can be installed almost over any surface including stone and other roofing membranes making it a very cost effective roof that will outlast any other roof.

A 40-year warranty comes with the Two-Ply Rubber Roofs we install.

We service all of Fairfield County, Connecticut, and Westchester County, New York.


Steps for Installing a Two Ply Roofing System

Step 1 – Preparing the Surface

  • Remove debris from the roof
  • Remove unnecessary obstacles like unused vent pipes, left behind A/C units.
  • Remove old roofing material off from existing flashing
  • Clean drain areas by removing roofing materials to expose drain flange
  • Clean scupper areas to expose copper

Preparing the roof for new Installation

When it comes to Roof Installation, the fewer obstacles on a roof, the less labor, and materials used the less the cost of the roof. Remove old Air Conditioner units and old vent pipes as well as old roof vents.

Roof Vents

Thes roof vents are designed to remove dampness from inside the rafters. They are not always beneficial and by removing them will do no harm.

Step 2 a – Gravel Stone Surface

  • Rake the gravel rock around to level off the roof. Move loose rock to lower areas to build up the area
  • After raking the gravel making a smooth surface and removing clumps and larger rocks, install a fiber base paper by using long screws and anchor plates purchased from a roofing supply warehouse. Make sure the fiberglass paper is not wrinkled when anchored down spacing the anchors every 2 feet. Be careful not to cover the metal flashing and drip edges.
  • Install a Modified Bitumen Self-Adhering Base over the fiberglass base. Be careful not to include any metal parts.
  • Torch Down a Modified Bitumen Rubber Membrane with ceramic granules embedded to the self-adhering membrane fusing them together.
  • Use special adhesives to attach the Torch Down Rubber to the flashing and other metal areas.

Step 2 b – Existing Modified Bitumen Rubber membrane

  • If the surface has a fresh coating of Aluminum Asphalt Coating (silver paint) then skip this step and follow Step 3
  • If the surface has a pretty worn down coat of silver paint and flaking off, then sweep brush any loose paint and debris off the surface. Use a leave blower to get the dust off.
  • Look for any wrinkles in the membrane and cut them away.
  • Remove the existing roofing membrane from existing flashing to expose the flashing around skylights, vents, walls and where necessary.
  • Fill areas where water would normally pond by installing ISO board over the existing roofing membrane.
  • Lower areas around a drain area by removing roofing material.
  • Install a self-adhering Modified Bitumen Base membrane in the areas where the surface had to be build up and where roofing material was removed to lower the roof.
  • Torch Down a Modified Bitumen Rubber Membrane with ceramic granules embedded to the self-adhering membrane fusing them together.
  • Use special adhesives to attach the RorchDown Rubber to the flashing and other metal areas.

Aluminum Asphalt Coating (silver paint)

If the existing roof has a coating of Aluminum Asphalt (silver paint) but is mostly peeled off or 80% of the membrane is exposed, then it is advisable to install a membrane directly onto it with a torch fusing the new membrane with the existing rubber membrane.

Step 2 c – EPDM Rubber Surface

  • If the EPDM Rubber roof is still firmly attached to the substrate and not wrinkled, then screw down more anchor over the top of the rubber.
  • Remove the EPDM rubber from all flashing detail as in A/C units, skylights, vent pipes, parapet walls, drains, and siding.
  • Clean and prepare the flashing and drip edges by removing adhesive with Laquer Thinners.
  • Install new flashing where necessary.
  • Cut away any wrinkled surfaces.
  • Install a Modified Bitumen Self-Adhering Base
  • Torch Down a Modified Bitumen Rubber Membrane with ceramic granules embedded to the self-adhering membrane fusing them together.
  • Use special adhesives to attach the RorchDown Rubber to the flashing and other metal areas.

Step 2 d – Plywood Substrate or Decking.

  • Install the necessary insulation with fasteners
  • Install Modified Bitumen Self-Adhering Base over the insulation
  • Install metal flashing where necessary.
  • Install drip edges
  • Torch Down a Modified Bitumen Rubber Membrane with ceramic granules embedded to the self-adhering membrane fusing them together.
  • Use special adhesives to attach the RorchDown Rubber to the flashing and other metal areas.

Step 3  – Detailing

  • Once the Modified Bitumen Torch Down Rubber is fused to the Self Adhering base, it is time to take care of the details. On every corner of skylights and a/c unit curbs and around every vent pipe, particular attention must be given to make the necessary patches.
  • Use special adhesives to make necessary seals around skylights, A/C units, and vents, vent pipes, and pitch pockets.
  • Attach the rubber membrane to the drain or scupper with special adhesives.
After installing the final layer, details like corners of skylights and a/c units must be sealed

Step 4 – Cleaning up

  • Pick up all loose roofing materials
  • Use a leave blower to blow the roofing surface clean.
  • Walk around to make a final inspection to see if all detail is taken care off.
Walk around on the roof and inspect every detail and see if you missed anything

My Roofing Experience.

My roofing experience began at the age of 10 when I shot the videos for my father’s roofing business in Norwalk, Connecticut. For the last eight years, I have been installing and managing roofing projects for my dad Naas, alongside my two older brothers, Erik and Andre, who currently owns Commercial Roof USA.

Proprietary Roofing System

In the last 30 years, my family has developed a proprietary roofing system which out-performs other roofing systems on the market today. This system consists of two layers of Modified Bitumen Rubber membranes fused together. The experience I have gained by being on the roof from a young age and working alongside other laborers has helped me to be able to run a roofing company and provide the best roofing possible.

Installing and Repairing all Roofing Systems

I troubleshoot leaky roofs and make the necessary repairs. EPDM Rubber roofs are the worst, and it takes a keen eye to find the leaks and make the repairs.

I am also the installer of our proprietary roofing system for all Commercial Roof applications. I manage roof projects of any size and making sure it meet our quality standards.

I also have started my own roofing business in Pittsburgh, Pennsylvania. As soon as it gets established, I will permanently move to Monroeville, a neighboring city of Pittsburgh.

A little about myself.

At the age of 16, my father Naas took me out of school to work on roofing projects amongst the other laborers. I was happy to be out of a class environment where I wasn’t thriving and enjoyed every minute of being on a roof.

Growing Up Fast.

I quickly became a man and learned the techniques of the roofing system they were using. It wasn’t long, and I was handling some of the smaller roofing projects by myself. At the time my father was still improving a particular roofing techniques that later would become a very key ingredient to the Two Ply Roofing System that we now use.
I finally moved up in the business and 2014 became co-owners with my brother Erik, of Commercial Roof USA.

Copper Specialist

Since then I also have learned to copper work. I have acquired the knowledge and experience to install high-end gutters, and I am a true copper-smith. I fabricate special flashing and copper standing seams. It takes a particular person to a work of art working with copper. I pride myself to provide the highest quality copper roof work.
Slate Roof Specialist
I also install slate roofs. I have learned the craft of how to cut and install slate roofs the old fashioned way. I use a sharp edged hammer to cut the slate tiles and make the holes for the nails.

Slate Roof Specialist

This method takes time but produces a far better looking roof than slate cut with a saw or grinder.
With all the different facets of roofing, I had to learn other kinds of crafts, including carpentry and plumbing.
My specialty projects are those that requires high skill and perfection. This type of project takes time and patience to accomplish the necessary precision, and I thrive doing it.

Erik Ferreira – Owner of Commercial Roof USA

I have been a roofing contractor for over seven years. I learned about roofing when I was a teenager shooting the videos for my father’s roofing business, Flat Roof Doctor. As time went by, I was put to work during school holidays and so got my roofing experience.

My father, Naas, have developed a roofing system that exceeds the longevity and quality of any other roofing system on the market today.

This system is a Two Ply Modified Bitumen Torch Down Rubber Roof that is fused together. It’s thicker than any other roofing material, and then ceramic granules are embedded on the surface to give it the needed protection against harmful UV’s.

Erik – Roofing Contractor and Consultant

With the experience and knowledge, I gained from working with my father; I provide the best roofing system that anyone can install. The years of trial and errors are over. I  can take any commercial roof and provide you with the best option and very competitive pricing. Although the materials used to Install a Two-Ply Rubber roof cost more than that of single ply roofing systems, the installation cost is considerable less.

Call me for a Free Consultation and Estimate for your next roofing project.


Learning Experience 

There is nothing better than learning first hand from someone that has been through all the trials that roofing could throw at him. My father Naas, had to learn and formulate techniques that were not available to him at the time. After many failures of installing a rubber torch down roof, he finally came up and improved techniques and products that worked the best. Today we have a roofing system that outperforms all other roofing systems.
