How many square feet is the average house roof?

The average roof area of a home in the United States is around 1,700 square feet or 17 squares, although there are numerous larger homes with roofs twice as big. Roofs are measured and estimated using "squares." A square is equivalent to 100 square feet of the 3-dimensional roof surface.

If your roof is 2,000 square feet, you'll have 20 squares. (2,000 / 100 = 20).

The cost of removing and replacing an asphalt shingle roof on average is between $1.20 and $4 per square foot. For a 1,700-2,100 square foot ranch-style house, it will cost you between $1,700 and $8,400.

How Many Shingles Do I Want on My Roof?

Roofers may either under or overstate the number of bundles required for replacement. This is due to the fact that a typical 30-square-foot home requires more than 30 squares of shingles. You must consider the waste. Waste accounts for about 10% of the material in most cases. That's equivalent to four squares. A typical home has 150 feet of a ridge and 240 feet of starter, so that adds up to another three squares. After all the extra shingles are taken into account, a 30-square roof will require 40 square of shingles.

Both pitch and starter shingles are crucial. Manufacturers do not make tab shingles to use them as ridge shingles on a wind speed-rated roof that goes up to 130 mph. Roofs with a similar life expectancy as the field shingles, such as those with a 50+ year rating, need enhanced "ridge shingles" that have the same lifespan (or longer) to maintain their structural integrity.

We've heard professionals compare this to automobile tires. Buying three 100,000 mile tires and one 50,000 mile tire for your car is comparable to utilizing cut-up 3 tab ridge shingles on an architectural roof. The difference in failure rates varies from one tire to the next. Similarly, if your ridges are not similar or of higher quality, they will deteriorate more rapidly. The lesson here is that you should make sure your roofing contractor uses the correct starter and ridge shingles for your house.

Nowadays, a square of 30-year architectural shingles costs around $78 (without tax), and a single square of 3 tab shingles costs around $65. The cost of shingles for an architectural roof replacement is calculated to be $3,120. The shingles for a 3 tab roof will set you back about $2,600.

In general, the following is the suggested replacement schedule based on the material employed: Composition shingles should be replaced every 12-20 years. Asphalt shingles should be replaced every 15-30 years. Wood shingles should be replaced every 20-25 years.

Now, I'll share five helpful hints for preventing roof damage and extending the life of your roofing:

1. Investigate Your Attic thoroughly

The attic is a perfect place to start when preventing roof damage. At midday, go up into the attic and leave the attic light off to see whether there are any points where the light shines in from the outside – even if they aren't proof of water leaks.

Check for stains or discoloration on the rafters, plywood, and attic floor framing. On the attic floor, inspect for damaged insulation. These are indicators of where it may have leaked during storms recently.

2. Get your roof inspected.

It's never too early to have your roof inspected, but right before hurricane season or just before the winter is the best time in Florida. However, an annual inspection by a professional expert will reveal any flaws or damage to your roof that you were not aware of and allow you to "nip it in the bud" before it gets worse.

Inspectors will check for shingles that are not correctly secured or bent, bowed, cracked, or broken. They'll also look for missing flashing in the eaves, roof cement around chimneys and vents that have developed cracks from hail, and other telltale indications.

3. Getting Ready For A Stormy Weather Season

You may also want to add roof cement underneath shingle tabs, particularly those that are loose or tend to pop up, to protect your roof from storm damage better.

Another thing you can do is add more shingles to the top of your roof. Adding more shingles to the top of a roof helps make it look better and adds additional wind protection.

Consider re-roofing your roof with a higher-quality shingle with more excellent wind resistance, UV light resistance, a tougher water barrier, and more extended longevity if it's old or of low quality.

4. Remove any potential wind missiles and falling branches

Debris in the yard that can be readily gathered and transformed into a "wind-missile" during a hurricane is one of the most common reasons for significant roof damage in general.

Remove any debris from your home and cut back overhanging trees substantially lowers your chance of a tree fall. Any trees that remain even though they are dead should be wrecked.

5. Reduce Shingles Heat Deaths

Shingles are tested for much of the year in humid, hot areas. Higher-quality, UV-resistant roofing is one method to combat the heat. Another essential component is ensuring that an underlayment adequately covers your shingles.

Finally, installing attic ventilation and a radiant barrier on the attic ceiling can aid in heat reduction and moisture problems that may affect the longevity of both the wood and shingles that constitute your roof.
