Northwest Construction, your local bathroom remodeling company, is also an expert when it comes to roofing. We understand that one of the most common concerns regarding asphalt shingle roofing is shingle blow-off.
What Causes Shingle Blow-Off?
There are three major reasons behind shingle blow-off:
1. Improper Nailing Pattern – Every shingle manufacturer identifies a narrow strip on every shingle for nail placement. Nails on an overlapping shingle should also catch the top edge of the next shingle. This is why nailing should be done by a professional. If nails are too high on the strip, they won’t catch the shingle underneath. This often leads to blow-off problems when the roof is exposed to high winds.
2. Too Much Overhang – The end of a shingle should have an overhang of up 1.5 inches at the edge of the roof, with a drip edge flashing installed. If shingles overhang too far from the edge, they are more likely to be blown off by high winds.
3. Roof Is Too Old – Architectural shingles have an average life expectancy of up 25 years if they are properly installed and maintained. However, if they are older than 25 years, or are exposed to severe weather, the shingles are more susceptible to blow-offs.
If you have problems with the exterior parts of your home, such as the roof and siding, you have to make a decision between repair and replacement. For shingle blow-offs, repairing and replacing have their own pros and cons.
Repair Pros and Cons
If you have several blown-off shingles, it might be possible to repair your roof. This is, of course, cheaper than replacing the entire roof. It’s also less messy and time-consuming. It will have minimal impact on your lifestyle, as well.
However, if you repair only the missing shingles, this can affect the looks of your roofing system, as the new shingles will stick out like a sore thumb. This is because the other shingles will have a more weathered look. The larger the repaired portion, the more unsightly your roof may become.
Replacement Pros and Cons
A full roof replacement leads to peace of mind, because you’re not worried that the rest of your roof might fail even after you’ve repaired the damaged shingles. You can also choose a new roof color if you were unhappy or bored with the old one. You can even replace the material altogether. By deciding to fully replace your roof, you are very likely ensuring better curb appeal and home value.
However, the cost to replace a new roof is nowhere near the cost of repairing only the blown-off areas. If your roof has multiple layers, the cost of complete tear-off is also significant. This will also take more time to complete. In many cases, homeowners have to arrange for temporary accommodations until their new roof is finished.
At the end of the day, these factors will affect your decision to repair or replace blown-off shingles, or do a complete roof replacement. It’s best to set your budget and talk to a professional contractor before making a decision.
