Therefore, this project is best left up to the professionals.

Do You Need To Hire A Roofing Contractor To Repair Your Roof

If youre a handy person or someone with construction experience you can probably repair some of these yourself. There are resources out there to help like videos or articles you can read to help guide you through the repairs. So no, not everyone has to hire a roofing contractor for repairs.

The one thing you definitely should hire a contractor for is to have your roof inspected and maintained on an annual basis. Theyll be able to catch most of the problems in this article before they cause damage to the interior of your home. Regular roof maintenance is the key to stopping a leak before it happens.

No matter if you decide to repair a leak yourself or if you call a contractor, remember quality roof installation and repairs play a huge role in how much life youll get out of your roof.

    As they age asphalt shingles can become more brittle and less flexible. That means that if they’re blown up by strong wind, they may break instead of snapping back afterward. Each of these tabs is actually only a third of a complete single and if possible it’s best to replace the whole thing instead of just one tab.

    Ways/steps To Repair Roof Flashing

    Although roof flashing serves as a protector from moisture, it can also go bad. There are times when the roof flashing has served its purpose, it eventually wears off. Metal flashing, for example, is prone to rust because they have regular contact with water. Having said that, different things are responsible for causing roof flashing to go bad, just to mention a few causes.

    Roof Repair Vs Roof Replacement: What’s The Difference

    If your roof deteriorates, youll need to decide whether to roof repair it or replacement the whole covering system.

    Heres a summary of their distinctions:

    Roof Repairs

    A roof repair simply entails repairing small flaws without having to replace many components of the roof. These might include a little roof leak that may be fixed with sealant or just one metal sheet being replaced. Roof repairs are usually fast, simple, and inexpensive.

    What are the indicators that you should consider repairing rather than replacing your roof? If the damage can be repaired by patching or coating, this is the preferred option. If your roof is less than five years old, it may also be a good idea.

    Roof repair still necessitates care, even if a damaged roof is no longer leaking. This indicates that a roof repair must be carefully planned and carried out with caution. As a result, reaching out to professional roofing contractors is usually the best option.

    We offer roof repair for roof leaks or any roofing services. Our team will examine your roof for flaws in craftsmanship that might lead to roof leaked or other roof damage in the future. Flashing around roof penetrations, including installed vent pipes, skylights, and chimneys, would all be red flags if they were installed wrong.

    Roof Replacements

    A roof replacement implies using new materials in place of many existing roof components. If the roof is severely damaged, you may need to replace it entirely.

    Roof Protection In A Flash

    Intersections of your roof, gutter lines, valleys, and corners where one part of the roof joins with another are the most common areas for roof leaks. Roof flashing installation and repair will prevent water from collecting in one place and penetrating the seams in your shingles and where the underlying wood joins together.

    Properly installed flashing, which is standard with all PJ Fitzpatrick roof installations, involves placing a plate of galvanized metal over these potential leak spots, preventing water penetration. This metal is seamless and runs along those problem areas as an added layer of protection. The joints and valleys in your roof, as well as intersecting pipes, skylights, walls, and chimneys should have flashing around them to ensure a waterproof seal.

    How To Find Roof Leaks

    How to Repair Roof Flashing

    Leaks often occur near projections or penetrations on the roof. To find the source of a roof leak, look for evidence like water stains and trace the leak up the roof. Use enough water to mimic heavy rains to soak the low side of the penetration. Let the water run over the low side of the penetration for several minutes. Work your way up the roof, isolating areas around each penetration. When a drip is visible, that will be the vicinity of the leak. Work your way down the roof, repairing damage as you go.

    Why Is Replacement Of Roof Flashing Necessary

    Settling new shingles is a big investment for foremost owners and it makes great sense to protect the stability and the durability of the roof for as long as possible. The main purpose of the roof flashing is to prevent the penetrations of the water from entering the roof. As you know, flashing is a low-cost process. Otherwise, there are many planned exceptions to upgrade the roof flashing for good results.

    How Do You Know If There Is Flashing Damage

    Rust

    Roof flashing can still corrode over time even if it comes with galvanized coatings. If the flashing already has rust, it will no longer protect the components of your roof against water penetration. It would need cleaning, sealing or a replacement.

    Holes

    It only takes a small hole for water to seep beneath roofing shingles. Small animals can also create tiny holes in your roof, which could allow water penetration. Flashing with holes would need to be sealed before they cause major issues, such as leaks.

    Cracks, Dents and Bends

    Cracks and dents on metals break the galvanized coating on steel. Once the flashing has been compromised, it would be more prone to rusting.

    Missing Parts

    High winds and extreme weather events can loosen the flashing on your roof. Repairs and replacements must be performed immediately if there are missing flashing pieces.

    Leaks Inside Your Home

    Signs of flashing damage can also be apparent inside your home. Check areas near your fireplace, windows and skylights for water leaks. Leaks can also occur in your attic due to flashing failure.

    Damaged Shingle or Siding

    Your siding can suffer from damage if the flashing does not shed water properly from the roof. You may notice signs of water damage on shingles in low spots of areas near flashing, such as bending and darkening.

    Mold or Stains on Fascia Boards

    When a contractor fails to install the drip edge flashing incorrectly, mold and water stains can develop on fascia boards.

    How To Install Step Flashing Where There Is No Wall Corner

    If your roof face connects to the wall cleanly without creating a corner, then you dont need to create a corner flashing piece. Instead, you will need to install kickout flashing to help guide the water into the gutter. While some professional roofers will make their kickout flashing by hand in copper, if youre using galvanized steel, it will be too tough to bend properly. Instead, buy a premade kickout flashing piece.

    Heres how to install kickout and step flashing:

    • Step One: Place your kickout flashing on the base of the roof, snugly against the wall. Briefly remove the piece and apply roofing cement where it will sit.
    • Step Two: Place the first piece of step flashing over the end of the starter strip, ensuring it leads directly into the kickout flashing. Use roofing cement and two nails to secure it to the roof deck. Place the nails on the base of the step flashing piece, so youre nailing into the deck. Also place the nails high, so the next course of shingles will cover them.
    • Step Three: Once the kick flashing and first piece of step flashing are secure, you have to apply a shingle. First, apply sealant to the base of the flashing. Lay a shingle on top of the flashing and nail it as usual. Notice that the bottom of the shingle covers the flashing base and nail.
    • Step Four: Finish the whole shingle course.
    • Step Five: To complete the step flashing, follow the same procedure as described above for installed step flashing with a corner piece, starting at step seven.

    Chimney flashing is the layer of sheet metal that connects the roof to the chimney. It is designed to be the seal that prevents water from entering your home by running down the chimney. Most often, when a chimney leaks, the leak originates in that spot. If you find water leaking through your ceiling, youll need to repair it quickly before more serious damage occurs.

    Step 1 Setting Up

    Since youre going to be going up on your roof, youll want to wait for a clear day. If your ladder doesnt have hooks at the top that can attach to the roof and hold itself in place, youll need someone to stand at the base and keep the ladder steady. It may be a good idea to wear a safety harness attached to a secure spot on the roof, depending on how high in the air youll be. Its easier to attach a rope to a bucket or toolbox and pull all your supplies up to you, rather than make multiple trips.

    Step 2 Stripping the Old Seal

    Before you can begin applying the new sealant, youll need to strip off all the old sealant, if there is any. Peel and scrape off as much as you can so you can get an accurate view of the flashing underneath.

    Step 3 Refitting the Flashing

    Step 4 Applying Caulk

    Step 5 Applying Flashing Cement

    How To Recognize That Your Roof Is Leaking

    Roof leaks can be both very evident and also more subtle. The only way you find some leaks is by going up in the attic to discover mold and mildew everywhere. Other leaks will be more prominent, creating water damage in your ceiling.

    Before you jump to the conclusion that the roof is leaking, make sure you rule out all other sources that may cause leaks, specifically leaks related to plumbing. Sometimes plumbing issues can create leaks that can easily be mistaken for roofing leaks.

    Moisture Or Roof Leaks

    Rain, snow, ice, hail, wind, and debris increases the chances of moisture penetrating the roof layers. Any moisture or water that can get through your roofing system will put your building at risk of molding, wet insulation, water damage, fire hazards, slips and falls, and structural deterioration.

    The best way to prevent moisture and roof leaks is to schedule regular inspections. Spotting leaks before they wreak havoc on your roof requires you to inspect skylights, maintain gutters, invest in attic ventilation, and install roof deck protection.

    What Are The Different Types Of Roof Leaks And Where Are They Located

    There are nearly as many types of roof leaks as there are types of roofs and the associated natural disasters or accidents that can cause them, but some of the more common ones are located in the natural weak spots.

    These include the vent pipe, a leaking roof vent, the chimney, the roof valleys, around the nails, around the skylights, around the dormers, and other structural issues damaged shingles, loose or missing nails, and ice damming can also cause roof leaks.
