A roof that is properly cared for can last a long time. Some of the ways to extend a roofs lifespan are by removing bird droppings and providing adequate attic ventilation.
It is also important to inspect a roof at least twice a year. This allows small problems to be addressed before they snowball into larger issues like leaks and structural damage.
1. Clean the Gutters
Keeping gutters clean is one of the most important things you can do to extend your roof’s lifespan. The gutters control where water flows after it leaves the roof, and if they are clogged with debris, the water can wash away the edges of the roofing material and even the foundation.
Gutter cleaning is best done by a professional, since working on a ladder can be dangerous. It’s also recommended that you wear gloves and eye protection when cleaning the gutters, to prevent getting stuck or scratched by any sharp objects that might be hiding in there. You should also wear comfortable, sturdy shoes and a stable ladder that you can lean on for support.
Begin by removing any sizable pieces of debris that are lodged in the gutters, such as leaves or twigs. Then use the hose to move the nozzle along the gutters, dislodging and washing away any clogs. When you’re done, be sure to check the downspouts for clogs as well. You’ll also want to clean out any debris that has washed out onto the ground, as this can stain or damage your siding and lawn.
It’s also a good idea to trim back any tree branches that hang over the gutters, as these can collect fallen leaves and debris and cause them to become clogged. You can do this yourself with a ladder and a pruning shear, or you can hire a professional to do it for you. This is one of the most cost-effective ways to help prolong your roofs lifespan.
2. Inspect the Flashings
The flashings are the areas of metal that seal the roof around penetrations like chimneys, skylights, and vent pipes. Over time, the flashings can corrode or loosen, and a leaky roof may follow. Regular inspections and prompt repairs can extend the lifespan of your roof.
If you have a roof made of asphalt shingles, make sure to check the flashings at least twice a year. The first inspection is before the summer storms, and the second is after the season changes. If you see any signs of damage, such as cracks or rust, have them repaired immediately. Prompt repairs prevent water infiltration and further deterioration of your roofing material.
Flashings are usually made from copper, galvanized steel, or aluminium-coated copper. Copper flashing is generally preferred because it has an incredibly long lifespan. However, if you are on a budget, other materials such as galvanized steel or aluminium-coated copper may work just as well.
When inspecting the flashings, look for holes or cracks in them. If you find a hole, clean away any debris that might have accumulated in the area, and then cover it with a piece of flashing that’s several inches larger than the hole. Then, secure the flashing to the wall with a liberal application of roof cement.
Another way to extend your roofs lifespan is to make sure that the attic has proper ventilation, ensuring your shingles stand strong for years. A poorly ventilated attic can cause heat to build up in the attic, causing your shingles to age prematurely. Proper attic ventilation also helps to prevent moisture buildup that can lead to rot and mold. Make sure that your soffits have intake vents and exhaust vents to promote adequate airflow.
3. Clean the Soffit
High-quality roofing materials, installed properly by a professional roofer, can last decades in Florida’s harsh climate. However, the most significant factor in extending your roof’s lifespan is consistent care that prevents issues from occurring.
This includes regular cleaning and inspections, as well as completing essential maintenance tasks that protect the integrity of your home’s roof. By taking these steps, you can avert problems like mold growth and structural weakening.
The first step in soffit cleaning is to remove any loose debris with a garden hose or pressure washer on a low setting. Once the soffits are free of debris, you can apply a mild cleanser that is appropriate for your soffit material. Next, rinse off the cleanser thoroughly with clean water. Finally, scrub the soffit using a soft brush or cloth, paying special attention to areas of heavy dirt or mildew.
Keeping your soffits clean is important because it helps to ensure that your attic ventilation is effective. Without proper ventilation, excessive heat and moisture can build up in your attic, damaging roofing materials and insulation. This can also result in a host of other problems, such as rotting wood, leaks, and mold.
To keep your soffits clean, you should follow a regular cleaning schedule, typically in the spring and fall. It’s also a good idea to do a quick check after severe weather events, as these can deposit debris on your soffit. Finally, you should trim any trees and shrubs that are close to your home to avoid damage during windstorms and to keep them from blocking soffit vents. In addition, you should also paint the fascia and soffit periodically to protect them from weather elements and to give them a fresh look.
4. Inspect the Underlayment
Roofing experts know that roof underlayment is one of the key factors in a roof’s lifespan. Underlayment protects the underlying layers of a roof from moisture, weather damage and other harmful elements. However, the lifespan of underlayment can be limited if it’s not immediately covered with roof-covering materials. Understanding how long roof underlayment can remain exposed is critical for roofing contractors and homeowners alike.
For example, 15-pound felt underlayment can only remain exposed for about two to three months before deteriorating. Once it deteriorates, water infiltration into the roof deck can occur, which leads to rot and mold. This can also cause problems for the home’s structure and foundation.
Synthetic underlayment has a longer lifespan than traditional felt underlayment. However, it is important to follow manufacturer guidelines and building codes when installing synthetic underlayment. This includes properly overlapping and nailing. Additionally, roof inspections and proper attic ventilation are important to prevent premature deterioration.
It’s also important to remove any debris that has accumulated on the roof, especially after a storm. Sitting debris saturates asphalt shingles, which shortens their lifespan. This is one of the many reasons why yearly roof inspections are so important.
If a homeowner or roofing contractor does not follow the underlayment guidelines, it can cause damage to the roofing system. This will result in premature deterioration of the underlayment, as well as voiding any warranties. A roofing expert can inspect the underlayment to ensure that there are no gaps or improper overlaps, which can contribute to early deterioration. They can also help the homeowner identify if the underlayment is leaking, which would require immediate repairs or replacement. The sooner this is done, the more likely the homeowner will be able to extend the underlayment’s lifespan.
5. Insulate the Attic
Insulating the attic is one of the best ways to improve a home’s energy efficiency and extend its roof’s lifespan. It controls temperature, prevents ice damming in winter and reduces heat buildup in summer. Proper insulation also provides a barrier against moisture that can damage shingles and drywall.
Existing attic insulation should be checked for moisture problems, and the air and vapour barrier should be repaired as necessary. Before adding new insulation, check the depth to ensure it meets minimum manufacturer specifications and that it is distributed evenly (see Part 2.2). If necessary, use a long ladder or extension cord to access the attic.
If a homeowner has enough headroom to add new insulation, two options are available:
Loose-fill insulation can be poured or blown in and is usually made of cellulose, fiberglass, rockwool or another material. It comes in rolls or blankets that are pre-measured to work with standard joist and stud spacing. If the existing attic insulation is cellulose, the homeowner should have the cellulose cleaned by a professional before adding loose-fill.
Rigid board insulation can be cut to fit over pipe vents and light fixtures. It should be installed so it extends from the wall top plate toward the attic. If this method is used, it is important that all obvious air leaks are sealed with caulking or spray foam before the rigid board is added.
For houses with attics that are half storeys or above, there may be limited space to add a new insulation layer and the ceiling below the attic should be covered with a gable vent system to allow for ventilation. In these situations, a contractor can help install an insulated attic floor and drywall, or the homeowner can stomp in a new layer of dense-pack loose-fill insulation and cover with a gable vent.
