Denver Flat Roof Repair is key to maintaining a strong, watertight roof. It’s especially important for homeowners in Western New York, where the weather can be rough on roofs.
Work on a flat roof cautiously, using a sturdy ladder and wearing a fall-prevention harness. Having a friend hold the ladder and help you stay secure is also a good idea.
- Clean the Damaged Area
Flat roofs are unique in that they are sensitive to debris and organic material accumulation. This can cause water to pool and lead to damage to the roof structure. It can also encourage the growth of algae and mold, which can cause leaks or discolor the roof surface. Regular cleaning and maintenance help prevent this from happening and extend the life of your roof.
Start by removing any standing water that has been collected on the roof. Alternatively, using a pressure washer or detergent, you can clean the roof’s surface It is best to work in sections, applying the detergent and then spraying it off. This will help to avoid walking on soapy, wet areas that could be slippery and dangerous.
If you are using a pressure washer, it is best to use a non-toxic detergent, such as a pH balanced roof cleaning solution or chlorine bleach. These will not harm the surrounding soil or plants. If you are using a chemical product, make sure to wear protective clothing and take precautions so that the chemicals don’t come into contact with your skin or eyes.
You should also check the drainage system to ensure that it is working effectively. This is important, as a flat roof relies on the drainage system to prevent water from pooling. If necessary, you should trim and clear nearby trees to reduce the amount of leaves that fall onto the roof and clog the drains.
Next, you should inspect the membrane for rips or punctures. Depending on the type of roof you have, this may be made from polyvinyl chloride (PVC) or thermoplastic polyolefin (TPO). It is vital to check these regularly to ensure that they are intact and protecting your property.
You should also inspect the insulation. If it is a built-up roof, you should check to make sure that the layer of gravel or chipped mineral material hasn’t dispersed and left bare patches. This layer is important for providing sun and fire protection. If it has gone missing, it will no longer be effective and you should consider replacing it.
- Repair the Damaged Area
When a leak appears on a flat roof, it is essential to respond quickly to minimize damage. This requires routine assessment and inspections, especially after severe weather events. A quick response can prevent a small problem from becoming a large repair bill and ensure the longevity of your flat roofing system.
A leak is often a result of a puncture, crack, or tear in your flat roof membrane. To repair these areas, first, you need to clean the affected area. This is important because a layer of water or debris can prevent the cement and sealants from bonding to the roof. It’s best to use a tough broom or other cleaning method that takes into account the type of roof you have.
Next, you need to dry the area. This is critical to the success of your flat roof repair, because the water or dirt can keep the materials you are using from properly adhering. After the area is dry, you can use a utility knife to cut away any material that has become loose.
Once the damaged area is exposed, you can apply a thin layer of cement. This should be around 1/8 of an inch thick and extend six inches past the damaged area. This will serve as a foundation for the patch you will place on top.
There are a variety of roof patches available for different types of roofing systems. It is best to match the patch to the type of roof you have, as a mistake in this step could lead to leaking. You can purchase a patch kit that will make this process easier.
While you’re on the roof, check that the flashing around chimneys, skylights, and other protrusions is correctly mounted. This is another critical step in preventing leaks, because it ensures that water doesn’t flow into the building through these areas. Also, inspect the drainage holes on your flat roof. You may need to clear out the gutters, replace any ballast, or repair a damaged drain line. Finally, remember that most flat roofs are designed with a slope to help with water runoff and drainage. Maintaining this incline will avoid pooling water and other problems that can lead to costly flat roof repair.
- Apply a Fresh Coat of Sealant
Your roof is the outer skin of your home, and it takes a lot of punishment. It bakes in the sun, soaks in the rain and can freeze in snow. This constant exposure to extreme temperatures can lead to ponding, cracks and discoloration. A good way to extend the lifespan of your flat roof is by coating it with a waterproof membrane like RD Elastodeck. To do so, first, make sure the surface is free of moss, dirt and other debris that can interfere with a proper seal. Before you begin, also check for any temperature or weather restrictions specified on the package of your chosen sealant.
To apply a new coat of sealant to the roof, first stir the bitumen roof sealant until it has an even consistency. Then, use a paint roller to apply a layer of about 1/2 inch thick over the entire roof. This is a great opportunity to replace any damaged shingles, too. Once the primer is dry, it’s time to start working on the mesh. Working on a flat roof is a little safer than a pitched one because it has only slight slopes, but still be sure to exercise caution and wear a harness to keep yourself safe.
Once you’ve placed the mesh on the roof, roll a second layer of roof sealant over it. This is a great chance to add another layer of thickness to the mesh, and also to help prevent water from seeping through to the area underneath it.
As you work, pay attention to the areas near walls, chimneys and other equipment on your roof. These are more likely to experience water infiltration than the rest of the roof and may need additional support from the mesh.
Once the mesh is in place and the sealant has dried, it’s time to add a reflective layer. This is a great opportunity to extend the lifespan of your roof and reduce energy bills by reflecting sunlight rather than absorbing it. Just be sure to follow the manufacturer’s instructions to ensure your reflective coat lasts as long as possible.
- Install Flashing
The number one cause of flat roof leaks is when the metal flashing that runs along a wall loosens or gives, and that is why it’s so important to make sure that this area is watertight. To do this, you’ll need to install new flashing. This is a fairly simple process, but you’ll want to use a skilled contractor for this part of the job, as it can be tricky and dangerous.
To start, you’ll need to locate all of the areas where water could potentially enter your flat roof. This includes the chimney, any type of pipe that goes through the roof, skylights, air conditioner curbs, and wall corners. Once you have located these areas, it’s important to take the time to clean and sweep them, as well as ensuring that any drainage holes are unblocked. You’ll also want to make sure that the flashings are in good shape and properly installed.
Once you have inspected the existing flashing, you’ll need to decide which material is best suited for your roof and climate. Ideally, you’ll choose a material that is compatible with the roof’s surface and your home’s siding. Once you’ve made your decision, you can begin installing the flashing. To do this, you’ll need a ladder, some shingles and flashings, and a hammer. Remember to always be safe when working on a ladder, and try to limit the amount of tools you bring to the roof. It’s also a good idea to have someone else remain on the ground to keep the ladder in place, especially if you’re not familiar with the building.
To start, you’ll need to install corner flashing. This can be purchased pre-made at many hardware stores, but you can also make it yourself if desired. To do this, simply cut a piece of flashing that is the same length as the corner, and bend it slightly so that it overlaps with the first shingle course. Next, you’ll need to apply some roof cement or sealant to the area where the flashing meets the shingles. Once you’ve done this, you can install the second piece of flashing and a shingle course above it.
