How long can I expect my new roof shingles to last? Factors affecting the life of your roof

You don’t need us to tell you that this isn’t a good sign because it’s not! If light can get in, so can rain, cold air, and snow. Check for light and also look for water stains. “If you find any, watch them over a few rainfalls and if they change shape or size, that means you’ve got an active leak,” says McGavic.

How much time you’ve got left: It depends on the extent of the damage, so call a pro. Small leaks can be patched, but larger ones, structural damage, and the age factor might make it wise to replace your roof sooner rather than later

Stop Ice Dams With Adequate Attic Insulation

The right amount of insulation in the attic reduces energy loss and the cost of running the HVAC system. Adequate insulation will prevent ice dams when there is snow on the roof.

In winter, your attic should be as cold as the outside air. When heat from your home rises through the roof because the attic lacks sufficient insulation , snow on the roof melts. Water runs down the roof to the unheated eaves where it freezes. An ice dam forms that prevents run-off. Additional water backs up under the shingles where it might rot the decking, cause mold or leak into your home.

Attic insulation installed costs less than $1.50 per square foot in most homes, especially when a layer of insulation is already there. The cost is recouped through lower energy bills within five years in most climates.

Roof Ventilation Is Essential To A Durable And Well

Excess moisture and heat in the attic quickly destroy roofs. Moisture gets into your homes attic from everyday activities like taking a shower, boiling water, and running a humidifier. If that moisture cant get out of the attic, it will cause havoc such as molded insulation, rotted roof deck and premature shingle deterioration. Heat causes shingles to cup and curve. It dries out the asphalt and makes it brittle, so it cracks easily.

There are several key ventilation points in any attic that allow excess heat and humidity to be vented.

Busy Vs Slow Season For Roof Installation

Most roofing contractors have busy season and slow season. During the slow season, you will get numerous benefits that would not be possible at another time.

1) You will likely negotiate a better price.2) There will be less stress and frustration, and good relations with the roofer.3) You will likely get better installation quality.4) You will not have to wait 3-6 weeks for your project to get started.

Keep in mind, that this will not apply to all roofing companies in your area. Some contractors are so well established that they have more work than they need, all the time.

These are usually larger companies that have an recognizable brand name. As a result, they are not interested in giving any discounts, just to get a new client.

At the same time, there are enough medium and small local roofing businesses that do experience a seasonal slow down in their work load. Many are more than happy to offer a few perks to get a new contract.

You just have put in some effort to get quotes from a number of pros, rather than agree to work with the first roofer that walks through your door.

    How Long Does A Slate Tile Roof Last

    How Long Does A Roof Last? (Homeowners Guide)

    Slate is a fine-grained natural metamorphic stone that is ideal for cutting into homogeneous roofing tiles. Slate roofs are a costly alternative, ranging from $600 to $1,500 per square foot, but they can withstand almost anything Mother Nature throws at them , keeping their structural integrity and stunning beauty. Manufacturers of slate tiles provide guarantees ranging from fifty years to a lifetime, and if the slate tile breaks, it may be simply replaced. Aside from the cost, the major disadvantage of slate tile roofs is their weight. Because the standard roof framework is insufficient to support these large tiles, the rafters on the roof must be strengthened before they can be fitted.

    Holding Down The Roof In High Winds

    Q: My daughter lives in hurricane country in a 15-year-old stucco house. Can she install hurricane clips to prevent her roof from blowing off?

    Don, McKeesport, Pa.

    A:Tom Silva replies: Those galvanized metal straps and clips that strengthen the connection between walls and rafters really do help to hold a house together in high winds. But it will be next to impossible to reach those spots from the attic. The only way to retrofit hurricane clips in most houses is by cutting out a section of the siding and the wall sheathing at every spot where a rafter rests on a wall or taking off the roof sheathing at the eaves.

    Here’s an easier option: Go up into the attic and run a bead of construction adhesive alongside each rafter where it meets the plywood roof deck. That simple measure will roughly triple a roof’s resistance of being torn off by wind.

    Q: My friend has a new 9,000-square-foot home and has had problems with the roof leaking. The roofing man and two painting guys have told her that the caulk on her roof was the source of the problem. They told her that she should have it checked every six months for cracking and possible replacement because the caulk doesn’t last long. I have never heard of this before and was wondering if they are pulling her leg or if this is a real problem?

    Shari, Park Hills, Mo.

    A:Tom Silva replies: I’ve got to tell you, it sounds like they’re pulling your leg. You shouldn’t need any caulking on a roof with proper flashing. You need a second opinion.

    Can You Install A New Roof On Top Of Old Shingles

    Warner Roofing, Inc. How long do asphalt shingle roofs last?

    Many homeowners wonder whether or not its a good idea to install a roof on top of existing shingles .

    The biggest reason for keeping the existing layer of old roofing is obvious extra cost. As we just explained above many people would rather avoid spending an additional $1,000 on removing the old shingles.

    Despite the high cost, doing this is absolutely essential! Leaving the old material will greatly accelerate the disintegration of the new roof and shorten its life cycle.

    This is because ventilation is reduced, which in turn increases the average temperature of the shingles, causing the product to dry up quicker and the granules to start falling off faster.

    Another reason why you should NOT leave the old shingles is because a roofer will typically not install underlayment between old and new roofing. If there are pre-existing problems in the leak prone areas: such as skylights, chimneys, vents and valleys, installing new shingles will not solve them! This means that your new roof will continue to leak.

    Failing to tear off old roofing will also negatively impact your warranty. Most large shingle manufacturers explicitly state that your material and labor warranty automatically becomes void, if their product was installed on top of an old roof.

    In most states, the building codes require that you remove the old roofing materials, if there are more than two layers of it already there.

    Irene, Riverside, Calif.

    A:Tom Silva replies: Yes, you need to strip the shingles. I don’t like to shingle over any old shingles, but one layer is acceptable. Two is not. A single layer looks better, lasts longer, and won’t put any unnecessary extra weight on the roof.

    How To Extend The Life Of Your Roof Shingles


    Since it can be a large investment to replace your roof, it pays to know how to make your roof last longer. Other than choosing the right type of roof shingles for your climate and not just for budget or aesthetics, here are five ways to extend the life of your shingles:

  • Maintain the area around your roof. This includes cleaning out the gutters so water doesnt pool and trimming nearby branches so the fallen leaves dont trap moisture and fallen branches dont cause damage.
  • Try to limit foot traffic on the roof and never use a power washer to clean it, which can dislodge the important granules.
  • Properly ventilate and insulate your attic. When air flows well, heat and humidity wont build up on the underside of your roof which causes the asphalt to dry out faster.
  • Get a professional inspection every year so you can catch small fixes before they become big expenses. This is especially important after a severe storm.
  • Another way to potentially extend the life of your asphalt roof is to paint your roof. Painting can add life to your roof, but it requires a lot of work. It can contribute to other issues, so it must be carefully thought out.
  • The most effective way to add life to your asphalt roofing is to rejuvenate it with Roof Maxxs scientifically-formulated, all-natural oil treatment. Roof Maxx has millions of microbeads of all-natural oil that penetrate your old roof and restore its flexibility and waterproofing protection.
