One day when I was walking around my college campus, I saw a group of people with these yellow tripods. At first I thought they might be photographers, but they sure looked like strange ones! I went up and asked them what they were doing, and it turns out they were a group of students from a construction class who were surveying the land for a project. I was fascinated. I was able to sign up for the class the next semester, and while it didn't stick or change my professional trajectory, it did create a new hobby for me! Ever since then, I've been interested in construction, from surveying to management to the actual building. I figured running a blog about it would give me a nice excuse to keep up my interests!

4 Subtle Warning Signs Your Home's Shingled Roof Needs Replacing

by Mike Brewer

At first glance, you may not think your home's roof has suffered any damaged. After all, you have not noticed any missing shingles or pieces of the roof laying on the ground. However, there are four subtle warning signs that mean your home's shingled roof needs replacing.

Small Granules Are Found in Your Rain Gutters

The tops of shingles have a rough texture due to the granules embedded in the asphalt material from which they are constructed. These granules protect the shingles by keeping rain, snow, and ice from accumulating directly on the underlying surface.

As the shingles age, these granules become loose and start to fall off. While it is difficult to see this granule shedding at first glance or even in your yard, you may be able to find them in your rain gutters.

If you find only a few granules in your gutters, this may be an early sign that the shingles' material is breaking down. However, if you find large piles of them, this is an indication that your roof is deteriorating quickly.

Roof Appears to Dip in Areas

You should be able to detect this next warning sign by examining your roof on the ground through binoculars. If dips start forming in your roof, this is an indication of severe structural damage beneath the shingles.

When new shingles are installed on your roof, they are attached to pieces of plywood to give them support and add an extra layer of protection for your home. However, if water starts seeping under the shingles, the plywood may start to rot. As a result, the wooden sheets start to cave in, creating dips in your roof.

Even if you see only one dip, this is a clear indicator that your roof is in serious need of replacing. Not only will the shingles need to be torn off, but the plywood will also need to be replaced.

Cracks Are Forming in the Shingles

Although you may not see any missing shingles, this does not mean that they are intact. There could be cracks in them indicating that they have become brittle and damaged.

To check for cracks in your roofing shingles, walk around on the roof and examine them closely. The cracks may appear as thin hairlines on the surface of the shingles.

Or, you may see gaps in the shingles showing they have completely separated. The only reason why they have not fallen off the roof is that they are still firmly attached by roofing nails. Eventually, the brittle asphalt will break around the nails, possibly making the shingles fly off the roof during the next wind storm.

Heating Bill Starts Rising

Another subtle warning sign that your roof is damaged and possibly has small holes or gaps is that you notice your heating bill starting to rise. Normally, when the heat in your home rises, the roof keeps it from exiting through the top. However, any openings in your roof cause the heat to escape, making your heater work harder.

By itself, an increase in your heating bill is not a sign that your roof is damaged and in need of replacing. However, when you notice a marked rise in your energy bill along with any one of the above warning signs, this could serve to verify your suspicions that your roof needs professional attention.

After finding one or more of the above signs, you may decide that your roof needs to be inspected by a professional to determine the true extent of the damage. If so, contact a roofing contractor at companies like Emmons Roofing & Siding LLC so they can look more closely at your roof and recommend your options for repairing the damage or replacing the entire roof, if necessary.
