It's Spring! While cleaning up the yard you might have noticed a few pieces of asphalt shingles lying about. Upon closer inspection, it looks like your aging roof might need some expensive work this year. But do you have to simply repair it or are you looking for a full replacement? Read on to find out some helpful tips to look for before calling the roofing contractor.
How Many Layers of Shingles Are There?
If your home is older than 20 years, there's a good possibility that you have two or three layers of shingles nailed to your roof. If this is the case, you're going to need to have all the shingles removed and replaced as warping and leaks can develop when the asphalt shingles are piled up too high. If you have only a single layer of shingles in place and have no leaks, you can likely go with a quick repair instead.
Does the Roof Have a Full Layer of Sheathing Underneath?
Historic homes built at the end of the 19th and early 20th centuries sometimes skimped on the construction of the roof. A "poor man's" roof put down nailing strips to which they attached the shingles. This leads to a greater chance that you can develop serious leaks and reduces the insulating value of your attic. If your old home has a poor man's roof, you will want to do a complete replacement to protect your home for the next fifty years.
Is the Attic Properly Ventilated?
Older homes were also built with minimal venting for the attic, which leads to moisture build-up, rot, and mold growth. If you only have a small vent cut at the end of the attic, you'll need to have more significant work done to protect the health of your family.
There are other indicators that ought to be taking into consideration before settling on the scope of work needing to be done. Give your roofing contractor a call for a thorough assessment.
