Why Vent?
Attic ventilation might seem like a minor consideration, but when properly installed, it can extend the life of your attic and roof structure — saving you hundreds of dollars in repair costs. 

During warmer months, ventilation helps keep attics cool. It helps prevent hot, moist summer air from warping the roof sheathing. It also stops shingles from deteriorating prematurely. What’s more, fresh air in the attic makes a home much easier to cool, which can result in lower energy costs. 

In winter months, ventilation helps reduce moisture to keep attics dry. It stops water from backing up under shingles, damaging insulation, and rotting the roof structure itself. It also helps prevent ice dams from forming. Ice dams occur in areas where snowfall and cold temperatures are common and pose a special problem because they prevent melt water from running off the roof. They can even cause leaks inside your home, resulting in drywall damage.

Shading: Possible Causes for Shading
Did you know? Unlike other roofing companies, D&J Development Inc.  is knowledgeable of the cause(s) of what is known as “Shading”. We have measures that we will take should shading occur. 

Shading is one of our leading causes of customer claims. There are several causes for shingles to “shade” and unfortunately, most are not evident until installed, or in the process of being installed.
Press variation continues to be a leading cause of shading. Some causes will weather out over time; however press variation typically does not weather out.

Residential

D&J Development Inc. always uses the highest quality materials available and we offer a wide variety of products from leading manufacturers. 

Flat or Low-Sloped Roofs
At D&J Development Inc., we also specialize in constructing and maintaining flat or low-sloped roofs. Since there are very few residential homes with this type of roof system, most roofers are not equipped to work on them. Our employees are fully knowledgeable and trained on the unique and technical challenges that flat and low-sloped roofs can present. 

Federal Tax Credits Still Available
In effort to drive down the country’s demand for energy, the federal government is offering homeowners tax credits when you add ENERGY STAR approved insulation or build a roof using ENERGY STAR approved shingles. D&J Development Inc.  can help you with both and offers the approved ENERGY STAR approved products. 

Ventilation
Did you know?

  • Many manufacturers’ warranties (of the roofing materials) become void if an attic is not properly vented.
  • A balanced ventilation system will reduce your utility costs and lengthen the life of your roof and A/C system.
  • Proper ventilation can prevent mold and mildew and other temperature and moisture related problems.

We realize that most people are not thinking much about their roof, but it is an integral part of your home which is an investment you value and want to protect. We all want to make smart financial decisions and be responsible with the energy resources we have. Therefore, we will assist you in understanding how your roof can save you money through lower utility bills, federal tax credits and reduced insurance premiums. 

There are many roofing materials available to construct a new roof for your home. We will work with you to determine the best materials to re-roof your Dallas home. Materials that meet your needs and your budget, while maximizing the aesthetics. We hope to make your home the most beautiful on the block. 

One of the most important things for any homeowner to consider is proper attic ventilation. We find that most homes are under-vented and almost always not in balance (providing appropriate amount of roof top exhaust equal to air intake). This is most critical during the high temperature months of the year. 

Attic ventilation is often overlooked by Dallas roofing contractors because most do not understand the dynamics of air movement and are untrained in fixing unbalanced systems. Our staff is technically trained to specify the right system for each home or building and to install it properly. 


  • Shading is one of our leading causes of customer claims. There are several causes for shingles to “shade” and unfortunately, most are not evident until installed, or in the process of being installed.
  • Press variation continues to be a leading cause of shading. Some causes will weather out over time; however press variation typically does not weather out.
  • Shading caused by press variation is most likely caused by shift to shift (downweb) variation in the average granule loss (scrub test) results. However, lane to lane (crossweb) variation also can cause shading due to crossweb weight variation, or problems with the pneumatic press system used in the press section, or equipment problems such as bad bearings, press rolls or wipers on the top press rolls allowing water on the sheet prior to initial pressing.


Blend Issue – an apparent mistake in the mixing of blends. This should have been caught during the blend check portion of the mini-audit. We’ve seen this issue on laminates, as well as 3 tab shingles. The cause for this particular claim could have and should have been identified prior to the material leaving the plant.
