Roof Replacement

A roof is probably the most important part of a house. After all, it keeps water out of the house. Although a roof replacement may not be ideal, its function will help you understand why this is critical.

But when should a roof be replaced? Several factors come into play when it comes to replacing a roof. For instance, if only a few shingles are damaged, this process may not be necessary. But, if your roof is leaking water/sunlight or is too old, replacing it is a necessity. Here are some signs that you need new roofing:

Roof Age

This is one of the major signs that you need to replace your roof. Normally, a roof lasts about 20 years. If your roof is not showing any signs of wear after this, more than likely it will soon. Depending on how it was constructed, it could last for a few more years. However, if it was constructed on an existing layer of shingles, it may be time to replace it. This is an important factor when it comes to replacing a roof.


Shingles that are buckling or curled are another sign that you need a replacement. Inspect the slopes, if the shingles are losing granules or curling, it could mean that they are past their prime. Also, it’s possible that the roofing system could be defective. Typically, a roofs shingles shouldn’t lift during harsh winds, be curled at the edges, or discolored. This actually shows that the system is declining. A few missing or loose shingles can be replaced but if the entire area is unstable, a replacement is imminent. More so, if the deck is sagging then you need to replace the roof as soon as possible.


If the roof shingles are missing or falling apart, it’s a sure sign that it needs to be replaced. Valleys are some of the most important areas of a roof. Rain and snow flow through valleys before going into the gutters. If the valleys are not stable, the roof might start leaking. Regularly checking for granules that look like small pebbles is important. In order to check for them, climb the roof with a ladder. But, if you are afraid of heights, try using binoculars.

If patches of light are shining through the ceiling, it may be time for a replacement. Remember, if sunlight is passing through the roof there is a high chance it could be leaking. It may be possible for animals to enter as well. Squirrels and birds can easily enter through holes and disturb you. A leaking roof shouldn’t be ignored, check for damage in your walls, ceiling or attic. When kept unrepaired, water leaks could easily lead to structural damage and even mold growth.

Chimney Flashing

Chimney flashing is also a huge concern. If the flashing is made out of roof cement and tar, it may need to be replaced with water filling. An example of this would be a metal flashing system. In most cases, damage to the flashing may be a sign of structural damage. More so, if the roof has a spongy feel like a trampoline, it means the decking is weak. Inspect your attic to see if there is any daylight or moisture in the insulation.


A ceiling with trails and dark spots can a sign of leaks or long term water damage. Indoor discoloration shows that there is a high level of water damage, and should be solved immediately. This could also be a symptom of moisture and mold. In short, darkening surfaces in a ceiling or attic means that you need a roof replacement.

In conclusion, it’s obvious that the cost of roofing can vary depending on the type and the size of material that you wish to use. Depending on the amount of materials needed and the roof type, replacement costs can vary a great deal. Before looking for estimates, know the condition of your roof. That way you are not caught off guard with an expensive estimate.

Know the lingo

An informed buyer is in a good position when it comes to negotiating the price. Before making a large investment, it’s important to educate yourself on the subject. The best way to do this is using the right language.


Depending on location, and the qualities you want, be aware of the various materials offered in the market. The most common is asphalt shingle which are low in cost and are good for any climate. Although metal is costly, it reflects the suns rays making a home cool and cuts utility costs.
