Roof Repair Columbus GA is a major undertaking that requires careful assessment of the situation. The first step is to find the problem.
Metal roofs are relatively easy to spot damage on, especially if hail has left dents. Also check for rust and separation between panels.
Mold and mildew growth are often the first sign of a roof leak. If left unattended, this moisture can cause serious structural problems in the house.
Flashing
A layer of impervious material that prevents water penetration into walls and roofs, flashing is crucial at areas like junctures where two roof slopes meet (called valleys), roof protrusions like chimneys or bathroom/kitchen vent pipes, and the edges of the roof (rakes and eaves). Most roofers use metal flashing (typically copper, galvanized steel, or aluminum) but plastic flashing is also available.
The lifespans of flashing are typically in line with the average lifespans of roofs, and when a roof is due for replacement, the flashing should be replaced as well. The best way to identify flashing problems is to check for lifted shingles around the flashing area. The shingles will lift when the flashing is no longer protecting them, allowing moisture to seep behind the flashing and into your home.
Other common flashing issues include rust and corrosion, gaps, or a torn appearance. These signs indicate that the flashing has worn out, and without a repair, you can expect water to leak into your attic or interior walls.
If the flashing is torn, a skilled roofer should be able to tuck it back underneath the shingle or tile. However, if the gap is too wide to cover with a shingle or tile, it may be necessary to replace the entire section of roof.
In addition to rust and corrosion, many flashing issues are caused by dramatic changes in exterior temperatures that cause the material to expand and contract. This causes the flashing to warp, allowing moisture in through gaps and destroying its protective capabilities.
Hail damage to roofs is another major issue affecting flashing. Small hail stones can leave indentations and gaps in flashing, impacting its ability to block moisture. These gaps and indentations can also cause leaking roofs, especially in attic spaces where the moisture can be particularly destructive. Unchecked flashing leaks can lead to mold growth, wet building materials, and attract cellulose-loving insects like termites. Eventually, these conditions can cause bowed and sagging wood framing in the attic and walls of your home. In severe cases, they can also cause rot and mildew inside your home.
Sagging
Sagging is a fashion trend that has roots in hip-hop culture and has been adopted by various celebrities. It can be seen as a form of self-expression and a way to showcase individuality. It can also be seen as a sign of cultural identity or community affiliation.
Sagging can also refer to a droop or excessive sheer of a ship’s centerline due to structural weakness.
Sagging in slang is also used to describe an older person whose skin or body has lost its elasticity and firmness. It can also refer to an old woman whose breasts have sagged and reached her stomach. The sagging of the breasts is a common side effect of aging and can be caused by various factors, including weight loss.
Built-up roofing (BUR)
Built-up roofing (BUR) is a long-established roofing system that is used for low-slope or flat roofs. It’s known for its durability and longevity. This is because the layers in BUR systems help to form a robust and enduring protective barrier against weather, heat, fire, ponding water, etc. With proper installation and regular maintenance, this time-tested system can last for decades. The multiple waterproofing layers also provide redundancies, meaning that if one part of the system fails, others can still offer protection to the building.
A traditional BUR roofing system is composed of multiple layers of bitumen, such as coal tar or asphalt, alternated with reinforcing fabrics, such as roofing felts. The result is a durable, long-lasting, and cost-efficient system that offers many benefits for commercial properties. For example, a BUR system is highly resistant to the transfer of thermal energy, allowing it to help lower a facility’s energy costs. It is also fire-resistant, with many of them tested to meet UL Class A and FM 1 standards.
While newer roofing technologies, such as single-ply membranes, have gained popularity due to their lightweight materials and easy installation options, BUR roofing continues to be a top choice for many property owners. The versatility of this roofing system makes it suitable for a wide range of buildings and climates, while its material flexibility adapts to building movement and simple installation options allow for cost-effectiveness.
In addition to its longevity and durability, a BUR system can also support a wide variety of applications, such as solar panels, mechanical areas, vegetative (roof gardens), and more. It’s this flexibility that makes it such a popular option for large commercial buildings and industrial facilities with flat or low-slope structures.
Like all roofs, a BUR system requires regular inspections and maintenance to prevent surface erosion. This includes minimizing the amount of foot traffic on the roof and, when necessary, using walk pads to distribute weight evenly. In addition, it is important to keep the roof free of debris that can trap moisture and exacerbate erosion. Lastly, it’s crucial to address minor problems promptly to avoid escalation of damage and potential leaks.
Shingles
Shingles are the primary protection against water intrusion on the roof and must be kept in good condition to prevent leaks. Damaged shingles can quickly snowball into larger issues and lead to water leaks in the home. A roof inspection will reveal the extent of shingle damage and determine the best course of action.
Leaking shingles must be replaced promptly to prevent further damage and costly water leaks in the attic, crawl space and walls. Water leaks can also damage insulation and interior ceilings and walls, requiring extensive repairs that must be done by a professional.
In addition to leaking, signs that shingles are in need of repair or replacement include missing shingles, curling shingles and dark spots on the shingles. The last two symptoms are indicative of moss or algae growth and can be masked by painting the affected area with appropriate color paints.
Whether due to age or poor attic ventilation, curling and buckling shingles are an indication of serious problems with your roof. These shingles are being pushed upward by moisture or improper installation and must be addressed by a roofing contractor to avoid structural and water damage within your home.
Shingles can also become brittle and lose their ability to protect your roof from UV rays. You will notice this when the granules begin to flake off from the shingle, leaving the asphalt exposed to sunlight and likely to wear down more quickly.
You can replace a single damaged shingle by first removing the nails that hold it in place. The nails are located in the top corners of the shingle, and you will need to remove one shingle above and below the damaged shingle. To remove the nails, slide a flat pry bar under the shingle immediately above the damaged one and gently lift it to free it from its sealer strip. This will expose the first row of nails underneath, which you can then pull.
Once the nails are removed, you can replace the damaged shingle by applying a bead of roofing sealant under the crack or tear and pressing down on it with a putty knife. Once the sealant dries, it will strengthen the shingle and increase its durability.
