The roof is one of the most important parts of our house because it protects our assets and everything that’s in the house. And even though roofs tend to deteriorate over time, the good news is, we can spot many roofing problems even from the ground. And while we cannot always solve roofing problems ourselves or apply DIY methodologies to fix them, it’s still better to spot the threats before they jeopardize our investments.
We have listed down common roof problems and how to deal with them.
Oil Canning
Oil canning refers to the moderate deformation or buckling of sheet material, seen commonly in wall material, metal roof or panels including copper, zinc, steel, and aluminum. The waviness or rippling of the metal are commonly caused by:
- Uneven stresses during the milling process. To prevent these, you need to ensure that the best end mills are used.
- Frequent stress from coil cutting and roll forming panels
- Uneven roof decking
- Thermal expansion
- Improper storage and handling
- Inadequate space for thermal expanding
- Contracting of the panels
Although oil canning can be prevented on the onset by purchasing thicker metal or opting for a low-gloss or matte finish to reduce reflectivity, there are not a lot of solutions available to fix this roof problem. You can try adjusting the internal supports to put tension on the face of the panel but if it doesn’t work, your next option will be panel replacement.
Scuffing and Scratching
Because roofs have paint applied to their surface, they are prone to scratching and scuffing, no matter how careful manufacturers, contractors, and installers are. One of the parties involved will most likely handle the materials improperly, during coiling or recoiling or upon installation.
While most manufacturers are willing to replace damaged or scratched metal panel, a paint job or touch-up pen designed to match the color of the roof can easily fix scratches.
Fading
Metal roofs are still the number one choice for people, despite other roofing materials like asphalt, tile, or cement being readily available in the market. The reason for this is metal roofs last longer. But people often hesitate about buying metal roofs because they fear they will fade or get discolored easily.
Fading occurs when water, pollution, moisture, and chemicals in the atmosphere react with paint pigments, breaking them down or lightening their color. One thing that people should understand is that no matter what type of pigment or resin is used by roof manufacturers, the color of the roof is bound to change at one point because of the roof’s exposure to the sun or outdoor environments.
When you notice that your roof is starting to fade, you can try to clean it. Sometimes, roofs seem to have faded in color due to a buildup of dirt, dust, algae, and moss. Cleaning by pressure washing or using chemicals might help, depending on what kind of roof you have. For example, if you have a metal roof, different shot blast media can be used to abrasively clean your roof. Techniques for cleaning concrete roofs will differ, with a pressure washer being more appropriate.
Apart from cleaning, you can also try to repaint your roof to make it look new and keep its glossiness.
Corrosion
There are many types of roofs available in the market that can withstand corrosion and degradation for decades. But, even though the materials used and the protective paint or coating systems are engineered well, corrosion can still occur, and it is bound to happen at some point in the lifetime of the roof.
Choosing the right type of roofing material and protective coating can prevent or delay corrosion. Protective coatings such as silicone, butyl, acrylic, and polyurethane can create a barrier between the metal and water in the atmosphere and prevent oxidation. If you live near coastal environments, make sure to ask your trusted contractor about what protective coating will work best for your roof.
Ponding Water
Ponding water refers to the build-up of unwanted water typically on a flat roof or roadway after storms, snow melts, or heavy rains. If the water is not drained immediately, it will affect and damage the membrane surface, and it will accelerate the deterioration of seam adhesives in single-ply roof systems, steel equipment supports, deck materials and roofing asphalt.
Ponding water can be addressed by repitching the roof, installing crickets and additional drains.
Leaking
Leaking roofs can create big problems, and this is the reason why it’s recommended to have them repaired or replaced by professional roofing service providers immediately. Leaks happen when the roof is not installed properly or when roof flashing wasn’t added upon the installation of the roofing system.
Flashing are painted silver malleable material, usually made of aluminum or galvanized steel. They are designed to cover roof butts and places where shingles meet other surfaces like walls and chimneys. Flashing prevents water from seeping in and causing damage to the ceiling or in the attic.
Leaks can also be prevented if gutter guards are properly installed.
Punctures
Roof punctures refer to the holes in the roofing material, caused by the combination of weight and sharp pressure applied in one small area. It is worth noting that every type of roofing system, including asphalt roofing systems, is susceptible to punctures. Punctures are commonly caused by technicians, plumbers, cable TV providers or basically anyone who often utilize the roof to perform their duties. Other causes of punctures involve wildlife, inclement weather, and trees.
Roof punctures are the leading cause of leaks and should be addressed right away. You can inform your roof manufacturers about the punctures, as these are covered by warranty. You can also educate maintenance personnel on how to prevent punctures. Cleaning and trimming excess vegetation can also be a preventive measure.
These are just some of the common roof problems that homeowners may face. So, if you’re looking to get your roof installed, repaired or replaced, make sure that you hire experienced and qualified roofing service providers, who use the latest techniques and technology. It also pays to do your research before choosing the roofing materials to go for.
Before you decide to invest in furniture and appliances, make sure that you have a stable, leak-free and long-lasting roof that will keep you, your family and your beautiful house protected and sheltered, any time of the day.
