Roof problems are a significant expense. They are responsible for reducing the service life of roofs through premature failure. This article is an informative list of the common problems that can be found in roofs. These problems often become more catastrophic if proper maintenance is not put in place.
Blow-Offs, Reduced Wind Uplift Resistance, And Billowing
Hot bituminous roofs with poorly attached flashing may have open seams and laps that may lead to blow-offs, reduction in resistance to puncture and code issues. Similar consequences can also be noticed with poor gravel embedment as well as the use of inadequate number of fasteners in the base sheet while applying the hot bituminous and torch-applied mod bit roofs.
Wind uplift resistance can be combatted if seams are not cured adequately on cold-applied mod bit roofs. Seams that are made with cold adhesives are not good until the adhesive has cured. If they are not cured and are exposed to wind and rain, moisture can leak the roof. The roof membrane can also be damaged by wind uplift.
Single ply roofs are also prone to billowing if they are not adhered properly to the substrate.
Faulty installations increase the dangers that a roof can be exposed to, which can then reduce the life expectancy of the roof. Workmanship is often one of the most common problems that can come up at a particular point in the life of the roof. Installations usually become problematic if certain preparations are not put in place. These things cannot be physically seen on the roof but are capable of leading to premature failure of the roof.
For instance, the lifespan of torch-applied mod bit roofs can be reduced if the sheets are not relaxed before installation. This shows that material preparation surpasses quality installation. It is therefore important to ensure that the crews hired for roof installation are knowledgeable in proper installation practices that are specific to the roof they want to install.
Ponding water is another problem that is common in all roof types. While designing a dead-level roof, there should be a slope with tapered insulation. Proactive measures should be taken to prevent building in ponding water.
UV rays that are being compounded by ponding water can adversely affect asphalt-based roofs. While installing hot bituminous roofs, improper mopping should be avoided as it can lead to voids in the membrane and can also result in ponding water thereby nullifying the roof warranty.
It is also advised that the source of the ponding water should be known before roofs are repaired. The source could be HVAC units that do not have condensate drain lines. Thorough inspection should be carried out before roofs are repaired. Drains should be checked to ensure that they do not have debris, silt and dirt.
