When is the best time to replace my roof?

Posted on: July 19th, 2016

If you need to replace your roof, then hopefully you’ve got some time to schedule when to have it done. The last thing you want is to be forced to have your roof replaced as soon as possible. This is because there are good times to have your roof replaced and there are bad times.

Unfortunately, if your roof is about to collapse, then you won’t have much say in the matter – but that’s why you should always get a regular roof inspection. This way you can identify the need to replace your roof before it becomes an emergency. The following is everything you need to know about when the best and worst times to replace your roof are.

The Summer Season

The summer is by far the best time of the year to have your roof replaced for one main reason – there’s less of a chance of rain or snow in the summer than any other time of the year. The last thing you want is for it to start raining in the middle of a roof replacement job as it can result in all kinds of water damage to your home.

There are, however, a few drawbacks to having your roof replaced in the summer. These include the following:

  • Summer is the peak roofing season – This means that contractors are extremely busy, and their prices will reflect this. Not only could it cost you more to replace your roof during the summer, but you may have to wait up to a month to schedule your roof replacement. You can avoid these issues if you schedule a roof replacement well ahead of time.
  • Shingles can be more easily damaged – Because all of the materials being used are much hotter during the summer (from the shingles to the nails), it means that the shingles can be damaged by a contractor that’s not careful as nail can easily go all the way through the shingles. A good roofing contractor won’t have any issues adjusting the pressure in their nail guns to avoid causing any damage.

The Winter Season

Although we recommend having your roof replaced in the summer if possible, there are a few benefits to having the job done in the winter as well. Because the winter is the off season, contractors won’t be in as much demand. This means that not only will they be pretty easy to schedule for whenever is convenient for you, but there’s a chance that you’ll get a discount compared to their summer rates as well.

However, there is a risk of snow and rain as well as the fact that new shingles may need to undergo thermal sealing, which may take some time to have done.

Summer is typically the best time of the year to have your roof replaced. To avoid scheduling problems and high costs, schedule a roof replacement well in advance. Be sure to contact us at Park Heights Roofing today in order to schedule a roof replacement.

Positives and Negatives of White or Light Colored Shingles

Posted on: July 13th, 2016

When choosing shingles for your roof of your Baltimore-area home, one of the decisions you are going to make is whether you want white (or light-colored) shingles or black (or dark-colored) shingles. Generally speaking, white shingles are the way to go. However, you should know a little bit about the positives and negatives associated with white shingles before jumping on them.

The Benefits of Using White Shingles

There are a few benefits to having a white roof. The main benefits include comfort and energy costs. During the summer, the temperatures will get relatively hot. If you have a black roof, then guess what’s going to happen? The heat outside will be absorbed into your home.

This can not only lead to a less comfortable house, but it can cause your cooling costs to skyrocket. Because your home is taking in more heat, your air conditioning system will have to use more energy in order to work harder and longer to produce the cold air needed to keep your home at your desired temperature. Considering how long the days are during the summer, you can expect those cooling costs to only grow as the summer drags on.

Unlike a black roof, a white roof will not absorb any heat. In fact, white is a reflective surface, which means it will do the exact opposite – it will reflect the sun’s rays, thereby helping to keep the heat outside of your home.

In addition to keeping your cooling costs down while improving the comfort of your home, a white roof will also help prevent problems associated with excessive heat. For example, if your attic has moisture problems, a white roof can help prevent heat from combining with the moisture to grow mold and mildew.

The Drawbacks of Using White Shingles

The main drawback of white shingles is that they won’t be able to absorb heat as well as black shingles would during the colder seasons of the year. As you can imagine, absorbing heat during the winter could help you reduce the amount of heat your heating system needs to crank out to keep your home warm. However, the following are a few reasons why black shingles won’t be that much more beneficial during the winter:

  • If it snows, your roof will be white no matter what, which negates the benefits of having black shingles.
  • Winter days are much shorter than summer days, so the benefits of having black shingles wouldn’t last for very long.
  • The sun is lower in the winter, which means your roof isn’t getting the direct sunlight it gets in the summers, which means that even with black shingles, you wouldn’t be absorbing that much heat.

As you can see, a white roof has a large number of benefits during the summer and a few drawbacks during the winter. However, the benefits far outweigh the slight drawbacks. For more information about installing white shingles, be sure to contact us at Park Heights Roofing today.

Algae & Moss Prevention and Cleaning for Asphalt Roofing Systems

Posted on: July 7th, 2016

Keeping your Baltimore-area roof in good condition is important to making sure that it lasts a long time. This includes cleaning off algae and moss, and taking steps to prevent it from growing on your roof. Although somewhat similar in nature – especially in the way they grow in moist conditions – algae and moss are different from one another.

What is Algae?

Algae can be identified by black discoloration and streaks on the surface of the roof. In fact, it’s often mistaken for mold or mildew. The dark pigmented sheath that causes the discoloration is used by algae as a way to protect itself from the ultraviolet rays of the sun. Once it becomes visible on your roof, it’s most likely already been present for months.

Algae won’t damage your roof, but it will affect the aesthetic value of your home and will have a negative impact on the effectiveness of cool roofs.

What is Moss?

Moss is a non-vascular plant that absorbs water through its leaves instead of its root system (like other plants). Moss spores can be spread by the wind as well as by animals. Unlike algae, moss can be damaging to your roof.

Specifically, it can cause the leading edges of your shingles to curl or lift, which increases the chance of strong winds blowing shingles off the roof. Severe moss problems can also lead to moisture damage.

Cleaning Moss and Algae

A solution of water and liquid chlorine bleach can be used to clean moss and algae from the roof. It will need to be applied using a sprayer and then rinsed afterwards using low pressure water.

Because of the inherent danger of climbing a roof to clean it – as well as the need to be extremely careful with the use of chlorine bleach – it’s recommended that you have a professional clean the moss and algae from your roof instead.

How to Prevent the Growth of Algae and Moss

There are a number of things that you can do to prevent algae and moss from growing on your roof. These include:

  • Trim any tree branches that hang over your roofThis allows the roof to be exposed by more sunlight, there by reducing the roof’s exposure to moisture. It will also help minimize the amount of debris that will accumulate on your roof that moss especially will feed on.
  • Keep air flow directed downward – Air should flow down the roof’s slope to prevent debris from being blown under the edges of your shingles.
  • Keep your gutters clean – Clean gutters will drain properly. If they become clogged, rainwater and moisture will build up near the roof.
  • Clean debris off the roof – Keep your roof clear of any debris that have collected using a leaf blower or another non-abrasive method.
