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.

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. […]

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 […]

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.

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 […]

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 […]

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.

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 […]

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.

Fair/Unfair Metals Touching

When two different types of metals, fair and unfair as they are called, 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 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. The roofing system is typically a pan or super-pan type made of aluminum and coated white. Insulation is sometimes used to help insulate and dampen rain patter. Pan roofs are large and lightweight. They are […]

No Wall Cap/Coupling

Separation firewalls are designed to extend past the flat 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 […]

Pitch Transition not Flashed

Whenever two different roof pitches transition a specially designed flashing is needed to bridge the slope change. This Millersville roof pitch transition does not have the correct flashing and is relying on sealant to disallow seepage. Over time the sealant will deteriorate and allow leaks. The pitch transition on this roof does not have any flashing […]

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 […]

Granules Loss

Asphalt does not hold up to direct UV exposure. Shingles use small colored stone chips called granules to protect the asphalt from environmental elements and to provide an esthetically pleasing look. Over time these granules wear off. When this occurs the asphalt surfacing starts to break down causing a downward turn in the shingle’s life. […]

Aluminum Ridge Vent w/Nails

Aluminum ridge vents are installed across the crown of the roof to allow ventilation. Although the vent manufactures allow these vents to be installed with aluminum nails, the nails they provide are not long enough to penetrate the decking. Most roofers will simply use the same nails as they use for installing shingles. However, these […]

Fiberglass Intermat Showing

Modified membrane construction starts with a fiberglass intermat. During production the fiberglass intermat is saturated with asphalt and dried repeatedly until the desired thickness is achieved. This intermat is not a waterproofing layer but is necessary to keep the membrane from cracking and separating. Over time the membrane surface wears down. Eventually the intermat will […]
