Metal Roof Slipping / Sliding

Interlocking Metal Panels are coming unclipped and sliding. This is caused by improper fastening. They are designed to be fastened in a specific area, increasing wind resistance and ensuring that both sides of the panel are attached to the roof. Without lifting up every panel and breaking the clips, it’s impossible to tell if the […]

Torn/Cracked/Broken Surface

As a roof expands and contracts the roof system moves. This is a daily occurrence and is associated with Thermal Shock. During movement the metal panels bind against each other. Sometimes a tree branch or flying debris may impact the roof causing damage. 3rd party damage is another issue. As people walk across the roof […]

Roof Recovered

We do not recommend recovering any roof system. Often roofers will advise consumers to simply install wood strips over the existing roof and install the new system on the wood batons as seen on this Brentwood roof. This causes trapped moisture and over time the original roof system will “bake”, causing rapid deterioration.

By |April 4th, 2012|Metal Roof Repair|0 Comments

Offset Not Correct

Metal panels are not a waterproofing material. When installed correctly, they do “shed” water. However, if installed on a flat roof, they would allow massive seepage. The way metal panels work is by their overlapping design. As the previous layer is covered by the next it creates a stair step water shed design, disallowing seepage. […]

By |April 4th, 2012|Metal Roof Repair|0 Comments

Improper Number of Fasteners

Metal is designed to be installed using special self-sealing screws. Each metal panel has a designated uplift and manufactures specify exactly how many fasteners per square foot are required. If metal panels are fastened outside the specifications the manufacturer’s warranty is voided and the roof assembly is out of code. This also leaves the roof […]

By |April 4th, 2012|Metal Roof Repair|0 Comments

Improper Fastener Installation

It is important that all fasteners are installed perpendicular to the roof’s surface and driven in at a perfect 90 degree angle. On this Pleasant View roof are areas where the fasteners were not driven straight in and the fastener heads are lifted slightly. Over time this can and will damage the roof system and allow seepage.

By |April 4th, 2012|Metal Roof Repair|0 Comments

Improper Fastener Type

When two different types of metals come in contact a chemical reaction occurs: Electrolysis uses moisture as catalysis at a molecular level to pass ions from one metal to the other. The process causes a deterioration of both metals similar to the effects of rust. Using the wrong type of fasteners causes a real concern […]

Fasteners Uplifting

“High fasteners” are a serious problem. During roof installation it’s easy for installers to forget about proper pressure setting on their screw guns. In most cases too many drills were hooked up to a single electrical line that was not sufficient to drive each fastener fully. At time of installation only the severe “high screws” […]

Tie-In not Sealed Correctly

The junction between your pitch roof and the flat roof is called the “tie-in”. This area is specifically important because there are two different roofing materials joining. A Greenbrier roof shows evidence that the tie-in area is not sealed properly. It is also very important that the two roof systems have the correct flashing detail and […]

Backwater Laps

When installing a roof system it is important to always start at the lowest point and proceed upward toward the roof’s peak. This ensures that each layer of materials overlaps the previous. Even on flat roofs, this principle is important. As water travels, on a pitch or on a flat roof, if two seams are […]

Flashing Rusting

Steel metal flashings exposed to the elements can rust over time. Today’s flashings are made of galvanized metal, a process that protects the steel core from rusting. Rust cannot be simply sealed over, as it will continue to grow. The rust needs to be cut out and a new flashing installed, then sealed properly. Since […]

No Sealant at Flashings

Although flashings bridge transitions in the roof, when not sealed properly they are ineffective. Flashing is designed to turn corners and breaks in a roof, which tend to have more movement than other areas. If not sealed properly, these flashings do little to stop water from entering the roof system. Here are voids in the […]

Valley Metal Buckling

Valley metal is installed by crimping the valley center, fastening the entire length of both edges and then applying mastic to cover the valley metal edge and fasteners. When valley metal is not properly pressed, fastened and/or sealed it causes buckling and waving. Since a valley is designed to channel water between two pitch areas […]

Gable End Flashing Not Correct

Gable ends are where a valley terminates into a roof’s surface, rather than running the entire length to the roof’s edge. They are quite common and add to the roof’s design. However, if not correctly detailed with flashings and sealants, the gable end is an area of concern. With the valley channeling large amounts of […]

Boot Not Sealed Correctly

As with all roof-top objects it is important that proper water flow and installation are considered. Flashing that is not layered correctly and sealant applied in the right junction areas allow water seepage. The boot flange was not installed correctly with the proper overlap procedure on this Nashville roof. Sealant has done a good job covering […]

Plastic Boots Used

As you know, plastic typically dries out rather quickly in our environment. The sun’s UV rays cause oil migration much the same as it does to exposed asphalt. On this Oak Hill roof a plastic stack flashing was used to seal the pipe. A gap between the pipe and surrounding flashing is visible and allowing seepage. This […]

Ell Flashing Not Sealed Properly

Ell flashing bridges the transition from the roof’s surface and a wall or upright surface such as a curb. On this Belle Meade roof the ell flashing has not been sealed properly and the shingles are pealing back from the flashing allowing seepage. This can be correctly by removing the area and installing mastic sealant correctly. New […]

No Ell Flashing Installed

Whenever a roof surface meets a vertical surface ell flashing is needed to bridge the transition and protect from seepage. On a Hartsville roof I found no ell flashing was installed at this detail. Although sealant may have helped avoid leaks, over time sealant breaks down. The correct technique is to install ell flashing here.

By |April 4th, 2012|Metal Roof Repair|0 Comments

Ell Flashing Uplifting

Ell flashing should be nailed every six inches on center. Not enough fasteners were used and the sealant has deteriorated. We suggest sealing the underside of the ell flashing and installing the correct number of fasteners as specified by code. On this Nashville roof another layer of membrane should be installed to cover the ell-flashing […]

Ell Flashing Behind Wall Surface

Ell flashing is designed to bridge the roof to wall transition and allow for protection against water intrusion. Water which runs down the roof and wall is caught by the ell flashing and channeled to the roof’s edge. It is important that the ell flashing’s end be flared so it sticks out past the siding/stucco. […]

Fasteners In The Valley

Since a valley is designed to channel water between two pitch areas a valley receives more water flow than any other part of the roof. A standard installation guideline on all roof systems is to never install fasteners in the valley’s center. Exposed valley fasteners disrupt the immediate flow of water. Because valleys are transition […]

Flashing Seams Separating

Flashing seams must be overlapped correctly and an adequate amount of sealant placed in between the overlap area to ensure proper waterproofing at the ell flashing transition area. The correct way to repair this area is to replace the flashing with new. That is the only way to ensure the flashing detail area will not […]

No Wall Cap/Coupling

Separation firewalls are designed to extend past the roof level and protect against spreading flames in the unlikely event of a fire. Many times these walls are simply stuccoed and painted. Over time the paint deteriorates, often at rates faster than walls due to the direct sunlight they receive, and allow moisture to seep into […]

Roof Vents Not Angled

Vents are installed on the roof to allow for attic airflow. These roof vents should not be longer than four feet in length and should be installed at an angle. As water flows down the roof it often is blocked behind the vent creating a small area of water ponding. Ponding water is water sitting […]

By |April 4th, 2012|Metal Roof Repair|0 Comments

Pitch Transition not Flashed

Whenever two different roof pitches transition a specially designed flashing is needed to bridge the slope change. Over time the sealant will deteriorate and allow leaks. The pitch transition on your roof does not have any flashing in it. Eventually the roofing materials and mastic used to seal this area will cause interior damages.

Loose Counter Flashing

Counter flashing is metal flashing installed into the wall to protect the roof membrane from coming loose from the wall as it transitions from the roof area. Counter flashing can also be used in conjunction with ell flashing at the same detail area. On a Belinda City roof the counter flashing, which has a concealed […]

Using two different […]

Pan Roof Tie-In not Correct

Aluminum structures are inexpensive and easy to install. They often add value to a building by providing additional usable space.

They are […]

Drip Edge with Flat Shelf

Often associated with gutter installation and plumb fascia boards, perimeter drip edge flashings can create a shelf or ledge about three inches from the roofs edge. This shelf creates a flat roof area at the roof’s perimeter. Since this roof system is not a flat roof, the perimeter flashings are not designed to allow for […]

The “base” and the “dragon tooth” overlay. When fasteners do not […]

Blown Off Cap

The most susceptible area on a roof to wind damage is the cap. Cap shingles are used to cover the hip and ridge areas of two adjoining decks.

Ell flashing bridges the transition from the roof’s surface and a wall or upright surface such as a curb. The ell flashing has not been sealed properly and the shingles are pealing back from the flashing allowing seepage. This can be correctly by removing the area and installing mastic sealant correctly. New membrane may need […]

Flashing Rust

Steel metal flashings exposed to the elements can rust over time. Today’s flashings are made of galvanized metal, a process that protects the steel core from rusting. Rust cannot be simply sealed over, as it will continue to grow as seen on this Fairview roof. The rust needs to be cut out and a new […]

No Ell Flashing Installed

Whenever a roof surface meets a vertical surface ell flashing is needed to bridge the transition and protect from seepage. On this Franklin roof we found no ell flashing was installed at this detail. Although sealant may have helped avoid leaks, over time sealant breaks down. The correct technique is to install ell flashing here.

No Sealant at Flashings

Although flashings bridge transitions in the roof, when not sealed properly they are ineffective. Flashing is designed to turn corners and breaks in a roof, which tend to have more movement than other areas. If not sealed properly, these flashings do little to stop water from entering the roof system. This is allowing water to […]

Ell Flashing Uplifting

Ell flashing should be nailed every six inches on center. On a Pasquo roof I found the ell flashing uplifted. Not enough fasteners were used and the sealant has deteriorated. We suggest sealing the underside of the ell flashing and installing the correct number of fasteners as specified by code. Another layer of membrane or shingle […]

Ell Flashing Behind Wall Surface

Ell flashing is designed to bridge the roof to wall transition and allow for protection against water intrusion. Water which runs down the roof and wall is caught by the ell flashing and channeled to the roof’s edge. It is important that the ell flashing’s end be flared so it sticks out past the siding/stucco. […]

New Flashing Needed

Steel metal flashings exposed to the elements can rust over time. Today’s flashings are made of galvanized metal, a process that protects the steel core from rusting. An example of rusted flashings was found on this Lebanon roof. Rust cannot be simply sealed over, as it will continue to grow. The rust needs to be cut […]

Fasteners In The Valley

Since a valley is designed to channel water between two pitch areas a valley receives more water flow than any other part of the roof. A standard installation guideline on all roof systems is to never install fasteners in the valley’s center. Exposed valley fasteners disrupt the immediate flow of water. Because valleys are transition […]

Boot Lapped/Sealed Correctly

As with all rooftop objects it is important that proper water flow and installation are considered. Flashing that is not layered correctly and sealant applied in the right junction areas allow water seepage. The boot flange was not installed correctly with the proper overlap procedure. Sealant has done a good job covering up the installation […]

Flashing Seams Separating

Flashing seams must be overlapped correctly and an adequate amount of sealant placed in between the overlap area to ensure proper waterproofing at the ell flashing transition area. Ell flashing seams were separating here and in need of additional sealant. The correct way to repair this area is to replace the flashing with new. That […]

Vent not Lapped/Sealed Correctly

Valley metal is installed by crimping the valley center, fastening the entire length of both edges and then applying mastic to cover the valley metal edge and fasteners. When valley metal is not properly pressed, fastened and/or sealed it causes buckling and waving. Since a valley is designed to channel water between two pitch areas […]

No Wall Cap / Coupling

Separation fire walls are designed to extend past the roof level and protect against spreading flames in the unlikely event of a fire. Many times these walls are simply stuccoed and painted. Over time the paint deteriorates, often at rates faster than walls due to the direct sunlight they receive, and allow moisture to seep […]

Plastic Boots Used

As you know, plastic typically dries out rather quickly in our environment. The sun’s UV rays cause oil migration much the same as it does to exposed asphalt. On this Donelson roof a plastic stack flashing was used to seal the pipe. A gap between the pipe and surrounding flashing is visible and allowing seepage. […]

Off Ridge Vents Not Angled

Vents are installed on the roof to allow for attic airflow. These vents should not be longer than four feet in length and should be installed at an angle. As water flows down the roof it often is blocked behind the vent creating a small area of water ponding. Ponding water is water sitting on […]

Ell Flashing not Sealed Properly

Ell flashing bridges the transition from the roof’s surface and a wall or upright surface such as a curb. On this Walnut Grove roof the ell flashing has not been sealed properly and the shingles are pealing back from the flashing allowing seepage. This can be correctly by removing the area and installing mastic sealant correctly. New […]
