New Roof vs. Re-Roof

Do I need a new roof or can I re-roof?

If you are having roofing issues or your shingles are becoming unsightly you may be considering a new roof. New roof installation can be pricey however there are a couple of options. Depending on the condition of your current roof you may be able to re-roof instead. Knowing the difference between a new roof as opposed to a re-roof will help you proceed.

New roof

If your home it needs a whole new roof this means that the current roofing material will be fully removed and the wood base will be inspected and repaired if necessary. A brand-new roof can last about 20 years without major problems. However the lifespan of your roof is based on how harsh weather conditions are and how well you maintain your roof. Inspecting the roof regularly for damage such as moisture will help.

The shape of your shingles is important because any curling or dimpling on the edges could indicate that moisture is being retained. If the shingles have missing parts or cracks this can lead to major problems with water leakage. If you have significant shingle damage you will most likely need a new roof.

Also if your shingles have moss or mold growing on them they will need to be replaced immediately. Discolored shingles or any dark streaks in your roof could mean that algae is starting to form which means that there is water leakage. Any type of algae or growth holds in moisture and causes major roof damage. Any presence of growth indicates that you need to have your shingles replaced.

Re-Roof

If your roof is in decent condition then you could be eligible for re-roofing. This process takes much less time and is less expensive than getting a whole new roof. If your roof has only one layer of shingles then re-roofing is possible by adding a second layer. There are a few important factors to keep in mind before choosing to re-roof.

You must not have any visible shingle damage or moss or algae growth on your current roof. If this is the case you need to have your roof repaired and replaced. Also your current shingles need to be flat and not curled up on the edges in order to place a new flat layer of shingles on top. If you have just a couple of areas on your current roof that need repair it may be possible to repair the small areas and then re-roof.

Keep in mind that it is impossible to check for major roofing damage when you re-roof as opposed to getting a new roof. You could be covering up damage that will only lead to larger problems. The layering of shingles could also hinder airflow which can affect your HVAC bills. Initially re-roofing will save you money however in the long run if you go with a full roof replacement you will have peace of mind for many years.

How Can You Tell When You Need a New Roof?

5 Tell Tale Signs you Need a New Roof

As a homeowner, you already know that preventative maintenance is required to help keep your home in tip top shape, but when should these repairs be made?  Often, the average homeowner does not know the warning signs to look for before something turns from a minor issue into a major disaster. This task is made even more difficult when dealing with your roof.  Knowing when you need a new roof is no different. Not only is it often neglected as it is hard to see from ground level, but to inspect it requires climbing a shaky ladder.  Many times small leaks remain undetected until the owner notices a stain on the ceiling.  Here is a list of what to look for before you need to start catching drips in a bucket during the next rain storm.

Shingle Shape

Are the shingles on your roof curling or peeling?  While shingles on your roof have a life expectancy of 20 to 25 years, areas exposed to direct sunlight for long periods will age faster.  If your shingles are curling and losing their protective granules this is a sign they are nearing the end of their projected use.  It may signify that your roof may not be properly vented retaining too much heat, or possibly has a leaking issue that is causing the roof decking to buckle.

Missing Shingles

If you are missing shingles, especially in the valley areas, then this is another reason that you may be in need of a new roof.  Valleys are an important aspect of the roofing dynamic, draining water and snow off your roof and into your gutters.  If this valley area is compromised then you may be in need of a new roof.

Moisture

When you are on your roof and you feel sponginess when you walk, then this may mean that your decking has become damaged by moisture entry.  Check inside of your attic to see if there is any visible daylight coming through, or if there is any wetness on the interior rafters or insulation. If any discoloration appears in your shingles, this may also be a sign your roof is in need of repair and should be inspected by a qualified roofer.  Remember, water runs down hill and will not always appear directly under the affected shingle, so close and professional inspection may be required to find where the leak has occurred.

 Shingle Granules

If your gutters are loaded up with granules from your shingles this means your roof may be nearing the end of its life cycle.  As shingles age, the tar that holds the protective granules to the surface gets dry and brittle and they easily wash off into the gutters.  Losing this layer allows water to penetrate the shingle and enter the house.

Flashing

Chimney flashing or other areas where exhaust pipes protrude is another area to be concerned with when it comes to sealing up your existing roof.  Often this is only done with roofing cement or tar, which will age and crack over time.  If this is the case, water will enter the dwelling where the chimney exits causing damage to the interior.  This should be replaced with a long term, water tight metal flashing.

The roof is the most important component of your house, without a sealed roofing system then all other areas will eventually take damage.  Knowing the signs to look for in the beginning will help you prevent major damage from occurring later.
