Maintaining Your Home's Roof
Imagine this scenario... The morning after a large wind and rainstorm, you venture out into your yard to assess the damage. A few small limbs have fall down, your favorite patio chair is overturned and – what’s this? – a shingle from your roof is laying in the yard? For any homeowner, this sort of minimal damage is likely to occur. And though it might not seem extensive, it is an example of one common roof problem a homeowner can encounter.
A sturdy and well-maintained roof is a vital component to your home's construction. It also is an important part of the appearance and visual appeal of a well-kept home. Since your home's roof serves as a protective shield from the outside elements, it needs to be kept in good condition. Inspections Unlimited recommends homeowners take a look at their home's roof at least once a year. Do this in autumn, before the harsher winter weather hits. You might also consider double-checking your roof in the spring to assess any damage that might have occurred during the winter months. Turning annual inspections into a habit can help homeowners catch problems before they start or get worse.
Whether you conduct a basic inspection yourself or turn to the help of your local Inspections Unlimited home inspector, there are several common roof problems that you might encounter:
Moss and Lichen
An easy-to-spot problem, lichen and moss can easily overtake an unmaintained roof. Not only is it an unsightly occurrence, moss and lichen can also damage the roof over time. The growth can occur on and around shingles, creating a damn that traps water and disables the roof to properly shed moisture. "This enables water to run backwards, up and underneath the roof's shingles. Water can soak through to the sub-roofing," explained Inspections Unlimited inspector David Shepard of Salem, OR. In this case, the shingles aren't able to properly protect the roof, resulting in water damage and possible leaks. Luckily, moss and lichen can be removed easily. There are many moss removal sprays and powders available on the market for at-home use. 
Leaves and Debris
Tree debris, such as leaves and small sticks, can also cause blockage and disrupt the flow of water off a roof. These materials collect in the valleys and wall edge and trap water from flowing off. Much like with moss and lichen, water is then pushed back underneath the shingles and into the lower layers of the roof. Debris can also collect in gutters and cause clogging. Remember to sweep or remove debris and ensure clear passages for water runoff.
Damaged or Missing Shingles
Just like the scenario mentioned above, it is not uncommon for roof shingles to come loose or fall off in harsh weather conditions. It may also occur as the roof ages, along with numerous other factors. Shingles are the outermost layer of protection between your home and the elements. They play a vital role in protecting against rain, show, wind, and sleet. During an inspection, check thoroughly for missing or damaged shingles. Signs of damage might include cracking, crumbling, or curled-up edges. Missing shingles expose the under layers of the roof to water and other damage, increasing the chances of a roof leak. Also keep an eye out for nails that might have popped out of the surface and pushed the shingle above it up. Shingles are replaceable, but unless you are experienced, should be can be installed with the help of a professional if you are do-it-yourself savvy. Homeowners can also contact a local roof maintenance service to replace broken or missing shingles and remove moss and debris.
Clogged, Leaky and Sagging Gutters
A clogged or leaking gutter is another problematic situation. Leaves and other debris from the roof can clog gutters and cause flooding. Inspector David Shepherd reminds homeowners to routinely clean out their home's gutters. "Water can back up to the top of the gutter and run over onto the roof," says Shepard. The overflowing gutter can then push water up and underneath lower shingles of the roof, where water and moisture damage can occur. The buildup can also result in stagnant water, which creates a thriving breeding ground for mosquitoes and algae later in the year. Also ensure that there are no leaks or cracks, and that the gutters are secured correctly to the side of the home. A sagging gutter might be a sign of stress that could eventually collapse it. Remember to check that downspouts are also correctly connected.
Shoddy Flashing
An important part in weatherproofing your home, flashing is a barrier - often made of sheet metal or other quality materials - that helps to seal out water and protect certain points of a building. Roof flashing can be found in roof valleys, around chimneys, vents and more. Check the flashing for signs of rust and deterioration. Flashing can also come loose, which enables water to squeeze through the gaps. Caulking or similar products can often be used to fill gaps or reattach loose flashing, but make sure you understand what you are doing before approaching the project yourself.
When it comes to inspecting the roof of your home, it is important to ensure a thorough and complete job. Inspections Unlimited offers a careful and detailed inspection of your roof's condition. This includes a close look at the roofing material, valleys and ridges, flashing and other important compntents. Your inspection report will help you identify problem areas and provide direction when exploring repair options - whether that means hiring a professional repair technician or tackling the repairs on you own. For homeowners dedicated to the art of do-it-yourself, always remember to approach your roof maintenance projects with care, using caution around ladders and when climbing on the structure. Proper maintenance and care can ensure the life of your home's roof, along with helping you avoid costly repairs in the future.
