Case Study:

Composite Shingle Roof Repair #2

This homeowner realized he had a problem when he saw water running down the inside and outside walls where it should not be. From the roof, you could not tell there was a problem until you looked underneath the shingles. But this roof does fit the profile of problem roof:

A - The lower valley where the roofs meet has a very low pitch angle.
B - Debris from nearby trees collects in this same valley, preventing water from draining off quickly, if at all.

If special precautions are not taken, the above conditions eventually lead to holes in the roof where water will enter during heavy downpours, which is exactly what happened.

rotted roof sheathing

The plywood sheeting had actually rotted clear through in one area.
closeup shows extent of roof damage

This was caused by trapped water in the roof valley, becoming deep enough to flow under the last row of shingles.

BK Roofing takes special steps to prevent this from occurring again.
damaged sheathing is carefully replaced

All compromised plywood is carefully removed and replaced with precisely cut new material.
repaired area is covered with special moisture barrier layer

Next, the repaired area is covered with a special shielding material that prevents damage from standing ice or water.
layers of new roofing felt are applied

Layers of roofing felt are then installed on top of the ice/water barrier.
flashing and new shingles are installed

Fix known problems promptly. Repairing damaged and loose shingles or tiles before leaks are detected can ultimately save you serious money. Damaged roof tiles or shingles over time, will eventually expose the underlying water barrier (felt). Once the felt is exposed to the sun, it won't take much longer for this area to "burn" out, and in a relatively short time, you can have water leaking into interior structures. As with many things in life, having a known problem corrected promptly can prevent it from turning into a bigger, more expensive problem later, and this surely applies to the roof on your house.
Keep your roof and gutters clear of debris. Many roof problems start when leaves, pine needles, and other debris accumulates in the valleys and lower areas of your roof. This leads to excess moisture and in some cases, rain water is prevented from flowing off efficiently, and can even get under the shingles and deteriorate the wood sheathing.
Tread lightly. Some roof types are quite susceptible to damage by simply walking on the roof in the wrong way, or with a "heavy foot". Contractors installing satellite dishes or solar collectors can unknowingly cause roof damage while installing their equipment. Cement tile roofs and cedar shakes are prone to this type of damage. The result can be cracked and loosened tiles or shakes which can now shift out of position over time.
Quality and Workmanship Counts. Whenever work is planned for your roof, make sure that your contractor is using high quality materials and methods, and most of all, select a contractor that has a reputation for high quality workmanship. Too many times, workers have been known to cut corners in an effort to save themselves time or money, which ends up costing the homeowners much more when the roof fails prematurely.
