If your roof isn’t in tip-top shape everything else in your home is on borrowed time. Every day that goes by with unchecked damage to your roof lets moisture into the structure, causing mold, mildew and other problems.
Look for staining, a musty smell, or other signs of moisture. Also inspect flashing around chimneys, vents and skylights. Visit https://www.fresnoroofingexperts.com/ to learn more.
The shingles that cover the roof are usually the first to show signs of wear. Look for bare patches, missing shingles, or discolored and wavy areas. The granules that protect the asphalt layer of the shingle from the sun’s UV rays and provide fire resistance may also start to erode or become dislodged. These granules may wash away in rainstorms or be carried by wind into gutters and downspouts, where they can clog them and lead to water leaks.
Shingles should be replaced when they are brittle, curled, or otherwise damaged. Ideally, replacement shingles should match the existing shingles in color and texture to maintain a consistent appearance. This is particularly important for a roof that is visible from the street.
Before starting to replace shingles, it is a good idea to gather a few basic supplies. First, check to see whether you have any old shingles in the garage or shed that can be used as replacements. If not, you can purchase a bundle of shingles at a home repair store for about $15 to $20 per square foot.
You will also need a pry bar, a hammer, and a utility knife. When working on the roof, be sure to use a secure ladder and have someone to help keep you steady as you work.
Before you begin replacing shingles, it is important to inspect the entire roof for damage. If you find a large area of damage, it may be better to remove all the shingles and replace them instead of trying to repair them individually. It is also important to make sure that the gutters are clear and that there is sufficient ventilation in the attic.
To remove a damaged shingle, slide a flat pry bar underneath the shingle and carefully lift it up to break the adhesive seal. Then, remove the nails from the shingle and the nail strip. Repeat this process until all of the damaged shingles are removed. If a shingle is cracked or torn but not fully broken, it can often be repaired simply by applying a thick bead of roofing sealant (about $4 for a 10-oz. tube) under the corner and weighing it down with a brick; leave it weighed down for 24 hours.
Flashing
Flashing is thin pieces of impervious material installed in the joints around penetrations like chimneys, skylights, roof vents, dormers, and wall openings to decrease water leakage into buildings. It’s important that flashing is installed correctly to prevent leaks and other problems, including rotting and mold growth.
If you notice the signs of roof flashing damage, don’t delay addressing them! The longer a leak goes untreated, the more serious (and costly) your roof repair will be.
A leaky roof puts your home at risk of water damage and can lead to a host of other issues, such as shingle deterioration, attic insulation degradation, wood rot, and structural issues. It can also create a damp atmosphere that encourages the growth of mold. If the moisture seeps into your attic, it can affect your home’s indoor air quality and contribute to respiratory illnesses and other health issues.
Flashing is a vital part of any roof, but it doesn’t always get the attention it deserves. If you’re not familiar with the seven different types of roof flashing, here is what you need to know:
Step flashing is a type of roof flashing that overlaps in “steps” where a joint meets a vertical surface like a dormer or chimney. This method of flashing protects against leaks by directing water to the gutter, where it can drain properly.
Chimney flashing is used to seal the area around a chimney, and it’s typically fitted alongside the chimney base. Valley flashing is used in a similar fashion, but it’s designed to reinforce and redirect water away from the vulnerable v-shaped wedges that are found at roof intersections.
Drip edge flashing is a strip of metal that’s set along the edges of a wall to protect it from moisture ingress and direct water towards gutters. Through-wall flashing is embedded in walls to prevent water ingress or to direct any that has entered back outside. Cap flashing is used above windows and doors to prevent water from leaking into the home. Other types of flashing include base flashing and counter-flashing, which are both used to reinforce the bottom of a wall.
Built-up roofing (BUR)
Built-up roofing, or BUR, has been around for over 100 years and is one of the most widely used materials for low-slope or flat roofs. It is durable and cost-effective, making it a great choice for commercial buildings. It is also energy-efficient, reducing cooling costs. Unlike single-ply membranes, built-up roofing has more layers that help to prevent thermal transmission between the exterior and interior of the building. It also offers greater flexibility for mechanical systems, solar energy, vegetative (roof gardens) and other uses.
While it has many benefits, built-up roofing does have some drawbacks. For example, the multiple layers can add to the weight of a roof, which may require structural considerations when installing or replacing a built-up roof. Additionally, the use of petroleum-based materials can make a built-up roof less eco-friendly than some other roofing options.
The most significant disadvantage of a built-up roof is that it can leak, especially if the roofing system has been installed incorrectly or not maintained properly. The seams can degrade over time, leading to water infiltration, so it is important to have a professional inspect the roof on a regular basis.
Fortunately, a build-up roof can be repaired by replacing the damaged section of the roof with a new layer of ply sheets, felts or bitumen. In addition, a professional roofer can apply an elastomeric coating to the surface of a built-up roof. This will prevent water from seeping into the roof and protect it from future damage.
Built-up roofs are durable and long-lasting, but they do need some maintenance to keep them in good condition. For instance, a BUR roof should be inspected on a regular basis to identify and repair any problems before they become major issues. Then, a professional can seal the damaged areas to prevent further water infiltration and prolong the life of the roof. A well-maintained BUR roof can last for 20 or more years, so it is a good investment for commercial buildings. Consult with an experienced commercial roofing company to learn more about this roofing option.
Gutters
Gutters are a key component of any roofing system, but they’re often neglected. They funnel rainwater off your roof in a clean and organized manner, reducing the risk of water damage to your home’s interior. Moreover, they protect your foundation, basement, and crawl space from moisture. Gutters are also essential to prevent moss and mildew from growing on your roof and around the perimeter of your house, which can threaten your family’s health.
A gutter system consists of troughs attached to the edge of a building’s roofline to collect and discharge rainwater from the roof. Once the rainwater reaches the gutter, it flows through downspouts, which are angled away from the house’s structure and allow the water to dispense onto the ground or into an underground drainage system.
If a gutter is damaged, it’s important to repair it as soon as possible. Leaks in gutters can cause rot and other structural problems. The good news is that fixing gutter leaks isn’t difficult, especially if you catch them early. The first step is to remove any debris that has accumulated in the gutters. This can include leaves, twigs, and even dead animals. If you’re unable to remove these items, hire a professional to do it for you.
Once the gutters are free of debris, you can use roof and gutter repair tape to seal any leaking spots. This can be purchased at most home centers and hardware stores. Before applying the tape, scrape off any old tar or caulk, and wire-brush the metal thoroughly to create a clean surface. You should also consider replacing the gutter if it’s too old or rusty.
Clogged gutters can be a major problem for homeowners, and it’s usually best to have them cleaned twice a year. A professional roofer can handle the job quickly and safely, using a tall ladder to reach all areas of your gutters.
Another easy way to keep your gutters functioning well is to add a downspout extension. This can help prevent overflows, and it can reduce the frequency of gutter cleaning.
