Flat roofing is more common on commercial buildings, than for residential properties. But with advancements in the materials used for this roofing style, more and more homeowners are choosing flat or “low-slope” options for their homes. One of the most common questions asked by property owners is how often they require inspection. This question is important, because low-slope roof maintenance definitely differs from pitched roofing.
Below, we explore the myths of flat roofs and their parts. We then discuss what a flat roof inspector should look for when checking its condition. Whether you own a home or commercial property with a low-slope roof, it is important to engage an experienced roofing contractor for periodic inspections and ongoing maintenance.
Myths of Flat Roofing
Many people, particularly homeowners, fear installing flat roofing because of common misconceptions about performance and maintenance. Two of the most widely perpetuated myths misinform that flat roofs are hard to replace and they are prone to water damage or leaking. Let’s look at these myths and dispel them, one at a time.
Are flat roofs hard to replace?
Flat roofs differ from pitched ones, in that the former style requires multiple layers of materials. This was once somewhat true. But the industry and materials used have changed over the years. Today’s flat roof building materials enable fewer layers for construction, due to technological advancements. In particular, waterproofing has vastly improved over time. As a result, installation, maintenance and replacement are all easier processes. Flat roofs of today also last longer than ever before.
Do flat roofs typically experience leaks and water damage?
Flat roofs can certainly experience pooling water, leaks, material rot or other damage from rainfall or other water exposure, when poorly constructed or improperly maintained. Really, any roof can experience these problems if not well built. By hiring an experienced flat roof construction company, you can prevent any such problems and enjoy the beauty and benefits of having a flat roof.
Key Parts of Flat Roofs
Flat roofs have multiple parts that pitched roofing does not. Although low-slope roofing all looks the same, there are multiple systems and styles to choose from for your construction project. Whichever style you choose, it will definitely feature three key parts they all share:
- Weatherproofing
- Reinforcement
- Surfacing
Selected materials make a significant difference in how your roof looks during construction. Some of the above layers are actually combined into one building product. But your flat roof must have layers that serve each of these functions.
Flat Roof Inspection
It is important to regularly maintain and inspect your flat roof. By doing so, you prevent leaks and other problems, also extending the lifetime of the roofing system. Always have your roof inspected by a knowledgeable professional after major rainstorms, as well as twice yearly.
Flat roof inspection should include:
- Absence of pooling water or problems with the drainage system
- Removal of fallen leaves, branches, loose debris, gravel and other debris from the roof surface
- Ensuring none of the drainage holes are blocked or otherwise hindered
- Inspecting chimney and skylight flashings to find cracks or rust that necessitate repair
- Checking the integrity of protective top layers to find bald areas where the gravel or chipped minerals have eroded away
- Looking for punctures, tears or wrinkling of membranes, as well as any other visible damage or flaws
- Repair of any damage to ensure the surface remains watertight and avoid additional deterioration or damage
- Replacement of the top layer of gravel as needed
Because of the dangers of working on a flat roof and the nuances of its inspection, maintenance and repair, it is important to have this work performed by a licensed and experienced roofing contractor.
