How do you know if your roof needs to change or just needs repairing? Making good decisions is key to minimizing short and long-term costs with any home improvement, especially for jobs like re-roofing. When it comes to your roof you need to make certain decisions before even hiring a contractor or choosing shingles. Should you just patch leaks or do you need to do a complete re-roofing. If you choose to re-roof, you’ll then have to decide whether to roof over your existing roof or whether to remove it. Either way it will cost you.
It’s relatively cheap to replace shingles that need to change due to wind damage or a fallen branch. It’s just a matter of removing the old ones and slipping new ones into place. The downside to this is that your patch job may not match the existing roof if you used saved shingles from the original roofing. A small price to pay if the life of your roof can be extended for several more years but if you eventually intend to sell you will want to have same color shingles installed.
Partial re-roofing is and option if the damage is only confined to one section of the roof. Repairing a section of roofing will also make it easier to blend new with old, because slight color differences will be less noticeable. They can create other problems. For example, if an asphalt roof already has two or more layers, all layers will have to be removed in order for partial re-roofing to happen. It’s possible you can experience lopsided ridges with the old roof being a few inches higher than the new one.
Even though it might be cheaper in the short term to do repairs it would be wiser in the long run to consider redoing the entire thing. This will likely be less expensive than doing one part now and the remainder a few years later.
When to reroof? This is a question that depends on several variables, including the shingles’ wear and age, the climate in your area, and your home’s susceptibility to future damage.
Once you’ve made the decision to reroof, you’ll have to decide whether you want to install your new roof over the existing one or take the old one off. The choice you should make boils down to whatever saves you the most money and prevents future problems down the line.
If you already have two layers shingles, the decision is made for you. According to the International Residential Code, if you already have two layers of shingles you can’t put a new roof over two or more applications of any type of roof covering. This has a lot to do with the weight of shingles and the effect it can have on the structure of your home.
If one layer of asphalt shingles is all you have, you may decide to have them removed but this isn’t a requirement. However, doing so may save you money in the future. Removing the old shingles will also allow you to inspect the roof deck or sheathing.
It’s important that you take the opportunity to examine the condition of your roof deck. You can check for wood rot and the presence of inadequate sheathing fasteners. Make all necessary repairs and add fasteners to sheathing, this will help to avoid the dramatic losses caused when sheathing blow roofs and allow rain to cause damage.
A new roof is more expensive than a repair but once done right it can last you for decades. One less thing to about when storm winds blow and more money in your pocket in the long term.
