If You Need  Commercial Metal Roof Repair

Your commercial building’s first line of defense from hazards like extreme heat, rain, wind, hail and fire is its roof. Your roof is also one of the most vulnerable parts of your building. This weather and other elements expose your roof every day to factors that will cause it to deteriorate over time, which risks damage to the roof and everything it covers.

Having a roof that protects your building begins with its design, the materials selected and proper installation when built. This doesn’t happen very often and could be  outside the expertise of managements usual activities. You need a continuous program of inspecting, maintaining and repairing – should be a routine part of your operations to extend the lifespan of your roof to ensure your roof is able to protect your business from weather issues.

This is how you find and address routine trouble spots so you can head off issues before they begin and correct them before they become bigger problems.

Visual Clues to Look for on Your Roof

Leander Commercial Metal Roof Repair ContractorsIf you see bubbles, it could show there’s trapped moisture inside the roof cover, which could mean leaks are coming, which will accelerate the early demise of the deck, which could  make the roof cover systems ability to withstand uplift forces from sever wind storms. Bubbles can also be caused by a release of gas from insulation board that could be trapped under the cover. To diagnose this issue, you can have a professional perform a roof cut or moisture survey.

The strips of metal or other impervious material thats installed around the edges of the roof, where the cover meets the wall is called roof flashing. It will also be installed around other things on the roof like vents and HVAC apparatus that come up through the roof to deflect moisture away from seams and joints. But, a gap in flashing or roof cover material could increase the risk of roof cover failure if there’s a high wind storm along with water infiltration and mold. Water can get through and enter below the cover due to tears in the the roof cover.

Here are some more of the common problems you’ll find on todays commercial roofs:

  • Surface Deterioration
    All roofing materials deteriorate over time from exposure to the elements at rates that are largely determined by the type of material and how it was exposed.  Inorganic materials generally tend to deteriorate more slowly than organic materials.  If areas of deterioration are showing, have the membrane  inspected for possible water infiltration. 
  • Moisture Ponding
    Poor roof installations can cause voids in the membrane, drains to be blocked, and result in water ponding on the roof. Other causes might be HVAC units without proper condensation drainage lines, drains blocked by debris, or a slope that is improper.  UV Rays added to ponding moisture can have negative effects on roofing. Before repairs are ordered, the source of the ponding water needs to be investigated. You should always inspect for these causes thoroughly before making any recommended repairs.
  • Poor Support for Equipment on the Roof
    The rooftop can be used as a location for many types of mechanical equipment – ladder struts, antennas, flag poles, signs, bracing, etc. They shouldn’t be placed on top of the roof unless absolutely necessary and they should never be mounted or placed directly on top of the roof membrane. You should have them mounted to a solid support structure or to raised curb-type supports. Flat flange or curb flashings can then be implemented to keep the roof watertight. Then roof replacement and recovering can happen without disturbing or removing the equipment.
  • Blistering
    Blistering happens when there are voids in the roof system.  Voids can show up from skips in bitumen mopping, debris thats trapped, substrates that are uneven, membranes not relaxing properly, or gases trapped due to moisture in the materials. During the day, as it gets warmer, air and moisture that are trapped in any voids expand. The pressure that develops in the void stretches the warm flexible membranes and displaces them which forms a blister. At night, the membranes cool, get stiff, and don’t return to their original shape. This creates a vacuum inside the blister, and more air gets drawn into it through tiny cracks in the membranes.  If you have just a few blisters, they usually don’t lead to issues, as long as the blisters remain watertight and don’t get too big. If a blister ruptures, moisture can reach the interface and degrade the strength of the membrane. Because of this, it’s critical to not break blisters. You should avoid stepping on them, especially when the membrane is cold. If a rupture happens, the blister gets to be too big, or the blister pulls the seam apart, a repair will probably be needed.
  • Penetration Flashings
    Penetrations going up and through the roof membrane are usually flashed in one of two ways. Single pipes and small vents will use flat metal-flanged flashings that are installed directly on the top roofing material and stripped in. Bigger penetrations and groups of smaller penetrations will use curbs made of metal, concrete, or wood, flashed in, and will usually have metal counter flashings installed with them.
  • Fastener Back-Out
    Back-outs are usually caused by shortcomings in the shank length, the nature of drill points, poor thread design, stress plates and fastener heads. If back-outs are found, check the roofing system to assess whether or not other back-outs are likely to happen. If a many fasteners have backed out or look like they’re starting to back-out, rather than getting repairs, you may need to consider a roof replacement.
