Residential Roof Replacement
If your shingle roof is starting to show signs of wear, needing several shingle roof repairs, or has reached its maximum life – it’s probably time to start thinking about a shingle roof replacement.

Wondering if your shingle roof needs servicing? Check for any of these warning signs.
1. Curling or Clawing Shingles
Curling or clawing shingles are a sign of both an aging roof system and excessive heat. Curled or clawing shingles are highly susceptible to wind uplift and ice damage. Shingles will become rigid and can break easily and lose tab edges.
2. Missing Granules and Bare Spots
Poorly placed downspouts, lack of eavestrough, or poorly designed valley drainage on a second storey can cause a waterfall effect that washes away granules over time. Aging of a roof system or physical damage can also cause bare spots and a loss of granules. When the protective granules of a shingle are lost the shingle begins to harden from heat and sun exposure. Granule loss on a roof system will accelerate aging and shingle decay and can become an entry point for water.
3. Broken or Missing Shingles
Broken and missing singles greatly weaken a roof system’s ability to shed water and can be an entry point of water. Two common causes of damaged shingles are excessive wind and physical damage.
4. Buckling Shingles
Buckling shingles are visible waved distortions that usually run vertically up a roof slope. Buckled shingles are highly susceptible to wind and ice damage and can be torn off easily. Overall roof age and wet or poorly installed underlayment are common causes of buckling shingles.
5. Damaged Flashings
Flashings located around skylights, valleys, eaves, rakes, wall details, stacks, and chimneys are all subject to separation, lifting, and dried out caulking. The flashing details can lift and separate due to general expansion and contraction. Expansion and contraction will cause fasteners to become loose and the bottom-flashing flange to lift thus allowing water to enter.
If you notice any of the signs noted above you may need to have your roof repaired or replaced by a certified roofing contractor. A roof leak is not always apparent immediately on the inside of a home; it can damage insulation and deck sheathing causing replacement costs to grow. Call us at Pine Valley Home Solutions before your problems grow.
Making good decisions is the key to minimizing near- and long-term costs related to any home improvement. This is especially true for large, complex jobs like reroofing. In this particular case, some of the most important decisions should be made before you hire a contractor or choose a shingle manufacturer.
The first decision is whether to simply patch leaks and damaged areas or whether partial or complete reroofing is in order. If you choose the latter, you’ll also have to decide whether to roof over your existing roof or whether to remove it. There are cost consequences either way.
Replacing shingles due to wind damage or a fallen limb is a relatively easy and inexpensive. Torn or damaged shingles can be removed, and new ones can be slipped in place. The downside is that unless your roof is relatively new and you happen to have saved some spare shingles from the job, your patch job may not match the existing roof. But that is a small price to pay if the repair would extend the life of your current roof for another 10 or 15 years!
However, if you plan to sell your home in the next few years, ask your contractor to order shingles that match as closely as possible. A roof with a prominent patch is unattractive and will not inspire a potential buyer’s confidence.
Repair or Replace Roof?
If the damage is more significant but confined to one side of the roof, partial re-roofing is an option that will cost thousands of dollars less than doing the entire roof. Repairing a section of roofing will also make it easier to blend new with old, because slight color differences will be less noticeable.
Counter to intuition, partial re-roofing jobs are more expensive on a cost per square (a 10′ x 10′ area) basis. They can create added problems, too. For example, if an asphalt roof already has two or more layers, all layers will have to be removed in order for the partial re-roofing to proceed. So in addition to increased labor and disposal costs, you may face the possibility of a lopsided effect at ridges, with the old roof ending up a couple of inches higher than the new one. Even when built up with a course of shingles and covered with a ridge cap, the hump may still be noticeable.
A New Roof—Cheaper in the Long Term?
Even if only part of your roof is showing signs of wear, it’s wise to consider doing the entire job while the crew is on-site with its scaffolding, ladders, and equipment. This will likely be less expensive than doing one part now and the remainder in a few years.
Tear Off or Roof Over?
Once you’ve decided to reroof, you’ll have to decide whether to install your new roof over the existing one or whether to tear the old one off. Once again, the choice comes down to saving a little money now and risking greater expenses down the road, or spending more now to do the job right and minimize future expenses.
If you already have two layers shingles, the decision is made for you. The International Residential Code (R907.3) says that you cannot put a new roof over two or more applications of any type of roof covering. Part of the reason has to do with weight and its effect on the structure of your home. A shingle in your hand may not feel as though it weighs much, but cover a roof with 1,500 square feet of them, and it’s nearly 15,000 pounds.
If you have only one layer of asphalt shingles, you may decide to have them removed even though you’re not required to. Doing so may save you money in the future. For example, if you live in an area that is subject to high winds, keep in mind that shingles will hold better if fastened directly to the roof deck. In addition, removing the old shingles will allow you to inspect the roof deck or sheathing.
The opportunity to evaluate the condition of your roof deck is valuable, insofar as you can check for wood rot and the presence of inadequate sheathing fasteners. By making any necessary repairs and adding fasteners to sheathing (especially annular nails or screws), you will avoid the dramatic losses caused when sheathing blows off the roof, allowing rain to cause extensive interior damage. Beginning your roofing job with a clean roof deck (old shingles and roofing felt removed) also means you have the option of adding ice-and-water-shield membrane along the eaves. It can only be applied to a clean deck but will help prevent damage due to ice dams.
A new roof is a big expense but should last you for decades. Do it right and you’ll have one less thing to worry about when storm winds blow. In the long term, you’ll also end up with more money in your pocket.
