What People Say About Us
Roof Repair, Infrared
Steve and his roofers did an excellent job. He was quick to respond to my call, and right from the initial meeting did a thorough job in assessing the required repairs. In addition to his nearly 40 years of experience with roofing, his infrared detection device is able assist in pinpointing exactly where the leaks originate. The guaranteed same day service is not an empty promise. His staff were onsite and completed the repairs by sundown and even had lights ready to do their work in the dark if necessary. To give you an example of the thoroughness, Steve brings a camera with a zoom lens that allows him to take before and (if requested after) shots of exactly what needs repair. Once you see these shots, the work becomes glaringly obvious and the after shots show the quality work that they've completed when placed side-by-side. Talk about resting easier, this should do it for you. It sure did convince my insurance adjusters and make them happy! They took one look at these and the detailed description of the work completed and had nothing but good things to say about the service. Basically they told me-- they never get this kind of excellent documentation from roofers and that we were fortunate to have gotten this company to perform our repairs. A+

Sheathing A Roof

Sheathing a roof is like icing on the cake.  Your home will not be complete if this roofing project is not done properly.  The ability for roof sheathing to stay in place during a windstorm or other inclement weather is most important.  It’s this connection that may fail during a hurricane or tornado, which causes water to enter the house while increasing damage to the structure of the home - both inside and out.  If roof sheathing is torn off, the trusses may lose their strength and increase the likelihood of a collapse.

To avoid having this happen, stay informed of your climate and the best possible method of protecting your home from damage.  Consider the various types of sheathing material, the process by which it should be installed and inform your contractor of your wishes.

Types of Sheathing Materials

Every roof has one of two sheathing options across the rafters - solid or open.  There are two types of solid sheathing materials, including panels and boards.  Panels are typically sheets of plywood or a wood product called oriented strand board (OSB).  These are preferred for most roofs because they are cost efficient and provide quick installation.  Plywood sheathing offers a sturdy nailing base with a higher cost.

Sheathing A Roof Step-by-Step

If you are installing a solid panel sheathing, start with one sheet and place it horizontally at one lower corner across the rafters.  If the area in which you live has high humidity, be sure to leave 1/8” gap between the ends of the connecting pans and a ¼” gap between the long sides.  If you live in an area with normal humidity, use half of these spacing measurements for your work.  The reason that this is important is, because during high points of humidity, boards may swell and the expansion gaps will be needed to allow them room to expand without damaging their neighboring boards.  If you want to install starter boards, they should be added before the first few panels.

If you want to add panel sheathing over existing open sheathing, consider removing the open sheathing all together and reinstall with thicker panels.  This will give the home better structure, but it is possible to apply over already present sheathing if necessary.

A Few Tips

When sheathing a roof, take extra care to ensure the nail is connecting with the roof structure.  If a nail gun is used, extra attention must be paid to make sure the nail is connecting properly.  If it misses, just place a neighboring nail correctly.  It is advisable that, because the heads are smaller and leave the sheathing panel susceptible to high winds, a nail gun should not be used when sheathing a roof.

Sheathing a roof is one of the most important steps among the roofing process.  When choosing materials and installation methods, inform your contractor of your concerns with high force windstorms, including hurricanes and tornadoes.  If you live in an area that is prone to harsh winters, let them know of your concerns.  This will help the contractor to be better informed and, additionally, will guide him/her in doing the job properly and to your satisfaction.  Any information that you can provide will be of great assistance to any contractor when sheathing a roof.
