Common Roof Problems

There are many common roof problems that can result in leaks and structural damage. These are some examples of common problems we see and repair.

Figure 1 - Improper step flashing can cause water damage.

Improper step flashing can cause rot and leaks when ignored. We make sure to install proper step flashing so the problem is eliminated.

Improper location can cause condensation to accumulate and result in rot or leak. The dryer vent should not be routed through the roof if possible.

Figure 3 - Re-insulation

In some older houses or vaulted ceilings there may be a lack of insulation. We can add a layer of insulation to better retain heat in your home. To do so properly requires the installation of vapor barrier prior to adding insulation.

Following the installation of vapor barrier. A layer of batt insulation is added to fill in the rafter space between the drywall and the current roof.

Once the batt insulation is installed, foam insulation and strapping can be installed. Adding the extra layer of foam insulation brings the total insulation value up reducing associated heating costs.

Figure 6 - Re-insulation

After the insulation and strapping is done we can re-sheet the roof. This allows for a vented air space below the shingles to allowing for proper ventilation as per shingle manufacturer's specifications. After the sheeting is done we can start prepping it for shingling. New metal gable trim and drip edge are added as well as underlay material on top of the sheeting.

Figure 7  - Finished roof after shingling.

Shingles are installed after all the insulation, strapping, and sheeting. A ridge vent was used in this figure rather than a a traditional vent because of the roof design.

Extra safety precautions were here by using 2" by 10" foot holds boards to ensure proper footing moving up the roof.

This type of project commonly includes the use of scaffolding and hand rails along the side of the building. Safety harnesses are also used when working at heights.
