Roof Installation Challenges and How To Overcome Them


Flat roofs, which have little to no pitch, are common in dry areas and on large businesses and warehouses. Although they are relatively easy to maintain, you may find several issues in flat roof construction than you would with other types of roofs. These are common challenges you may encounter and how to fix them.

Flashing Installations

It can be difficult to install flashing on a flat roof, especially for anyone who doesn’t have prior experience. You may think that applying concrete or tar to the joints on your roof will protect your structure, but these products do not provide a waterproof seal.

If the flashing isn’t installed just right, you can experience leaking that will cause water damage to the building. Unfortunately, you may not realize that your roof is leaking until you have your roof repaired or reinstalled. This could mean extensive and expensive repairs.

Improper Ventilation

Ventilation eliminates excess moisture from inside your attic or under your roofing materials. This prevents mold and mildew from developing or growing in your building. Proper airflow requires cross ventilation. Your building contractor who is familiar with flat roof construction may suggest that you install a pop vent and ventilator on opposite sides of your roof.

Poor Drainage

Flat roofs tend to hold water after heavy rains and snow. This is especially dangerous when your roof has edging that sticks up over your actual roof. In fact, you could experience a roof failure if your drainage is poor. The best time to install drainage systems is when your roof is initially installed, and a center drain is often the most effective because it is the lowest point on the roof. However, this type of system also requires piping that allows the water to flow down and outside the structure.

If your home or business has a flat roof, work with an experienced, reputable roofing contractor who understands flat roof construction.
