Inspecting Your Homes Roof
Posted on Jun 27, 2012 by Roger Frost
A roof protects primarily against rain. Depending upon the nature of the building, the roof may also protect against heat, sunlight, cold, snow and wind. Roofs height can range anywhere from 1 to 3 stories for the typical home inspection.
The location of the building and the climate play a huge factor in the type of roof you may encounter during your residential or commercial building inspection. The requirements of the building that it covers, the available roofing materials and the local traditions of construction all play a part in how the roof may be constructed.
Sheet metal in the form of copper and lead has also been used for many hundreds of years. Both are expensive but durable, the vast copper roof of Chartres Cathedral, oxidised to a pale green colour, having been in place for hundreds of years. Lead, which is sometimes used for church roofs, was most commonly used as flashing in valleys and around chimneys on domestic roofs, particularly those of slate. Copper was used for the same purpose.
The angle of the roof above the horizontal is referred to as the pitch, which is expressed as a rise of inches per foot. For example, a roof that has a rise of 4 feet over a run of 12 feet has a 4/12 (or 4:12) pitch. A roof with a rise of 12 feet over a 12-foot run has a 12/12 pitch; expressed in other terms, the same roof has a 45 rise. typically asphalt shingles are not used on a roof with a slope under 3/12. A roof with a pitch lower than 2 /12 (or 2 feet of rise in 12 feet of run) is classified as a flat roof.
Guttering systems, like everything else, have evolved greatly over the last couple of hundred years, starting out as crude wooden troughs and ending up with the vinyl and metal systems that we use today. It is fair to say that most guttering systems are high-maintenance. Homeowners with conventional uncovered gutters are required to regularly clean out vegetation and debris that get blown into them. Gutters often need to be re-fitted when severe weather detaches them from the fascia.
Aluminum guttering is quite often formed on-site from a roll of sheet aluminum. This leads to fewer joints, but those at corners and downspout connections should still be fully evaluated. It should be noted that when the roof slope is increased the amount of water and ice coming off the roof increases and has been known to knock typical 4 inch gutters off the roof.
