How often a roof needs to be replaced depends on the type of material used, local weather conditions and the quality of the material and the build. Different roofing materials have different lifespans, and so it is important to establish the lifespan of the material itself.

There are numerous factors which influence the lifespan of a roof. Once the roof material has been determined and its respective lifespan estimated, a thorough roof inspection will allow for an accurate decision as to whether the roof needs replacing or not.

When an ice dam forms on a roof , ice and water can work their way up under the shingles and leak back into the house. Also, strong winds can blow rainwater under shingles. Self-stick roofing underlayment can prevent this because it sticks to the roof decking to seal out water. It also seals around nails, which keeps water from leaking through nail holes.

Rolls of self-stick underlayment have a plastic backing so the material won’t stick to itself. The backing is separated down the middle. Line up the lower edge of the roll with the outside of the drip edge. Peel back part of the uppermost backing on the roll, and nail the top corner of the underlayment to the decking. Start pulling the roll across the decking using the backing, making sure the material is lying as flat and as straight as possible as you pull.

As described earlier, looking for a leak is usually best done from inside the attic, but this method really only works if the leak is relatively severe.This is because a slow, random leak may take a while to stain the roof decking, which is usually OSB or plywood.

    Here are a few pro tips most roofing contractors use to find a leak:

    Your Asphalt Roof Was Damaged From A Storm

    How to remove and replace asphalt shingles roofing repair

    The weather where you live and the kind of storms your roof faces factor into how much wear and tear it goes through. But that isnt the only thing you have to worry about when it comes to weather.

    This may seem obvious, but heavy storm damage will also lead to a roof replacement. If high winds come through and rip up your shingles or a tree falls on your roof then clearly youre going to need a new one.

    If you have a metal roof system, then hail damage to your metal panels will lead to a replacement if the integrity of the metal is compromised. But for an asphalt shingle roof to be replaced from hail it has to cause damage to the soft metals that are on your roof.

    Whatever kind of storm damage your roof has, its important to know if your roof is covered. Read this article on replacing your roof through homeowners insurance.

    Metal Shingles Leak Overview

    Metal shingles provide a durable, lightweight option for homes not designed for a heavy roof, like tiles. In contrast to fiberglass/asphalt, these shingles can often be used on low slope roofs making locating leaks easier.Finding leaks caused by physical damage on a metal roof is also fairly simple. Generally speaking, metal shingles will not cause a leak unless obvious damage or decay is present. This is why many metal shingles carry up to a 50-year warranty.

    If the shingles have been obviously damaged by a falling tree limb or another heavy object, the leak can sometimes appear much smaller than it is. This is because leaks can be caused by the tiniest of perforations. For example, if violent physical damage occurs via a falling object, it can loosen, but not detach, the surrounding shingles which will lead to eventual failure.Therefore, it is a good idea to check any shingles within a 24 circumference of the leak. Metal shingles tend not to flex, so impacts tend to bounce off, rather than be absorbed. This can cause small leaks after an impact that is tough to locate and may simply be a loose tack.

    How To Replace Damaged Shingles

  • With the area prepared , slide the new shingle into place. Line up the bottom of the shingle with adjacent shingles to each side. The new shingle will not quite fill the gap between the shingles on either side equalize the gaps between shingles side to side. You may find that the shingle needs to be lifted slightly to slide over staples, nails or the next shingle slide a hand up under it and carefully lift slightly.
  • Very carefully roll up the shingle just above the replacement until the tar line is well exposed as this is where the nails should be driven in.
  • Drive two nails on each tab, or six nails per shingle. The nails, if driven through that tar line, will hold both the new shingle and the one beneath it.
  • Allow the upper, rolled up shingle to relax back into place, helping with a little hand pressure. As shown in the photo, it is a good idea if possible to apply a little heat to help melt the tar and seal the new shingle to the older existing one underneath it.
  • The job shown needed replacement of four shingles, plus one that was damaged in the process of “unsticking” it from the broken one, for a total of five. It took about an hour to do the task a small amount of effort to protect the investment of your home.
  • The upper shingle is curled up, revealing the nailing area. The nail is placed on the tar line and driven through both the new shingle and the older shingle underneath it.

    How To Repair A Torn Or Curled Asphalt Shingle

    1Carefully lift the torn piece or damaged corner, and, using a putty knife, carefully spread a layer of asphalt roofing cement under it. Be careful not to smear the cement on exposed portions of roofing.

    Wood Shingles Keak Overview

    How to Replace Asphalt Shingles

Some may split, while others may twist.This uneven surface tends to create opportunities for leaks, making the underlayment as important as the shingle. In many cases, when a wooden roof leaks the issue can be very difficult to locate from the outside unless the issue is obvious.

    Damaged shingles can seriously cut into the life of a roof. To keep your house secure, it’s important to regularly evaluate and replace damaged shingles to make sure your home is safe and dry.XExpert SourceRoofing Contractor & Maintenance ProfessionalExpert Interview. 14 July 2020. You can learn to properly evaluate, remove, and replace damaged shingles efficiently.

    Basic Components Of A Roof

    StructureThe rafters and trusses that support the decking.

    The boards attached to the roof rafters to cover the house.UnderlaymentA waterproof layer installed in between the roof decking and the roofing material.

    FlashingMetal strips laid into valleys and joints of a roof, such as around chimneys or pipes, to prevent water leakage. This includes drip edge flashing, which is situated along the edge of the roof.

    Roof coveringThe shingles or tiles that make up the outermost part of the roof. This can be made from many materials, such as asphalt, metal, rubber, slate or clay.

    How To Decide Between Re

    If you are a homeowner with minor issues or leaks, which typically occur as the roof reaches the end of its lifespan, but the roof is in overall good shape, re-roofing may be for you.

    If you only have one layer of asphalt shingles on your roof, you may also be a good candidate for re-roofing. However, if only a portion of the roof needs to be repaired, you may not want to forego re-roofing because only doing one section of the roof may cause it to be uneven in some areas, which will be noticeable.

    If the roof already has at least two layers of shingles, both layers of shingles will need to be removed prior to partial re-roofing, which can increase labor costs as well as the cost for disposal. It also costs more for partial re-roofing because roofers typically charge per 10 x 10 square.

    On the other hand, if your deck shows signs of major water damage, is sagging, or has large amounts of mildew or mold growth, then the deck will need to be repaired, which means you will need a complete roof overhaul.

    A full roof overhaul may also be a great option for those who just want to rest soundly knowing your deck and your shingles are in pristine condition. Once the old materials are fully removed from your roof, the roofer will inspect for any signs of damage and repair any defects for a strong and sturdy roof that gives you peace of mind, as opposed to simply not knowing until it is too late, which is the risk you often take with re-roofing.

    Removing The Old Roof

    How to Remove an Old Asphalt Shingle Roof and Replace Rotten Roof Decking

    Typically, the old shingles should be removed before the new roofing materials are laid down. However, there are cases where a new roofing material is to be placed over the old one.

    This is usually only possible when installing metal roofing over asphalt shingles and only if one layer of shingles is already on the roof. The removal of the old roof is not just to make space for the new roof, it is also so that the roofing contractor can inspect the wood decking underneath the roof.

    Although removing the old roof might sound like a simple task, its not as easy as you would imagine. It requires the right equipment and the right manpower. For instance, the crew may need a large dumpster. Without one, they could find it difficult to dispose of the old materials.

    They also may consider covering up your foliage with tarps. As they remove the old roof, some of the materials will fall to the ground. They can protect your foliage and make clean-up easier by covering them up. They may also place plywood against your windows and doors to prevent damage to them.

    Its also important to consider the timing. You dont want to remove the old roof and leave it off for weeks at a time. In fact, you should only remove the old roof when you have the new materials ready for installation. This can avoid unnecessary damage to the structure of your home.

    What To Expect If You Replace Your Roof Before You Sell:

    If your home demands a full roofing overhaul to sell, then prepare to fork up a significant sum to cover the project. HomeAdvisor reports that homeowners spend on average between $5,346 $10,787 on roof replacement, though Jennifer and Andrew Oldham have witnessed clients spend as much as $60,000.

    The good news is, a roof replacement returns a fair amount of investment: 61.2% to 65.9% by Remodeling Magazines estimate. Industry research leaders the National Association of the Remodeling Industry and the National Association of Realtors echo this calculation in their joint 2019 Remodeling Impact Report. New roofing ranks the number one project for appeal to buyers and likely added value to home at resale. The report estimates that a new roof brings an average $8,000 return, with 33% of agents stating that a new roof has helped them close a sale.

    Tear Off The Old Shingles

    Its impossible to properly install new flashing and underlayment if you dont tear off the old roof beforehand. When tearing off the existing shingles, be sure to remove all the old nails or pound them flat. Protruding nails will tear holes in your new shingles. If you have movable items near your house and youre worried they might get damaged, relocate them. Invest in a few large tarps to protect your plants and landscaping and to catch the thousands of nails that will rain down off the roof. It can be downright impossible to remove old self-stick ice-and-water underlayment, but its OK if you have to leave it in place. And if at all possible, have the rented trash bin parked close to the house so you can toss in the old shingles right from the roof.
