Roof coatings are an economical way to enhance your commercial roof’s longevity without having to replace your roof. While coatings work on most roofing systems, including modified bitumen roofing, there are certain conditions that indicate whether it’s suitable for roof coating. Enchantment Roofing takes a look at what these conditions are.
The outer roofing should have a solid surface that works with liquid coating, which means roofs covered in gravel are unsuitable. Roofing that’s vulnerable to punctures, such as single-ply roofing, has to be inspected and restored before roof coating can be applied for best results. The roofer has to be thorough in performing restoration and repairs, as everything will be sealed when the coating is applied.
The substrate is the roofing layer that the outer material is fastened to. On metal roofing systems, the substrate can be made of plywood or OSB (oriented strand board). If there are signs of deterioration, or if it’s too old, you may have to reconsider having the roof coated, as you may end up preserving a roof that’s structurally unsound. Pay attention to transitions between the roof and the wall, or penetrations such as exhaust and HVAC vent pipes. Dislodged, damaged, or missing flashing in these areas can expose the substrate and can introduce moisture damage.
If the roof tends to form ponding water, do not coat the roof until this is addressed. Standing water can weaken the roof coating, so you need to observe the roof and make sure it is completely dry within 48 hours every time it rains. A level roof, with the correct slope and clear drainage system, shouldn’t have issues with ponding water.
A roof that’s halfway or even three-quarters of its expected life span is ideal for roof coatings. At this period, problems caused by installation errors or manufacturing defects will have been already addressed. With proper care and maintenance, such roofs will only be showing minor signs of aging, which can be restored by a capable roofing contractor.
