This is the transcription of the video (scroll down to watch it) where Tim Carter of
AskTheBuilder.com shows how easy it is to replace a damaged asphalt shingle.
"A lot of people wonder if replacing the asphalt shingles is a tough job.
Now let me tell you that the hardest part of the entire job is getting on and off the ladder.
To replace an asphalt shingle, all you need is couple of simple tools.
You need 2 different size pry bar and a hammer.
Now what youīre going to do with those?

Another free caclulator is ready, I named it an asphalt shingles costs estimator.
It estimates cost of the asphalt roofing (only 3-tab shingles only, but Iīll add other asphalt roofing products soon) and its weight (for roof dead load caclulation).
Please check it and let me know your opinion.

Requirements on sheathing used on roofs shingled with asphalt patterns
The asphalt shingles are very flexible roofing material and they are probably least demanding on framing and sheathing preparation.
The flexibility of asphalt roofing patterns enables their usage on various types and shapes of roof and gives the architects really generous place to play around with the roof design.

Asphalt shingles can be used wherever on roofs with slopes from 15 to 90 degrees (3/12 to vertical wall roof) and the only thing that is required when roofing with asphalt patterns is tha the underlayment must be as flat as possible.

Basically, there are 3 groups of reasons why the asphalt shingles fail.Low-quality material, asphalt shingle defects
The most important material defects are as follows:
- missing or insufficiently adhesive thermo (self-adhesive) spots/stripes;
- low-end bitumens used (low temperature stability, low melting point, low UV - ultraviolet radiation - resistance);
- non-acceptable physical parameters, like e.g. too high absorptiveness, low shape-stability, high weight;

- high sheathing humidity;
- non-flat underlayment;br />
- wrong dimensions or distances between rafters, beams, etc...;

Very often, the asphalt roofing problems appear if the roofers (usually DIYs) over-estimate the adhesivity of the self-adhesive strips of the asphalt shingles.The asphalt shingles with the self-adhesive strips
These self-adhesive strips are special adhesive surfaces provided by the shingles manufacturers to help to stick one asphalt pattern to another and many people think they work well and cause seamless joining of particular asphalt shingles and so the homogenization of the whole roofing.

Unfortunately these people are wrong. The self-adhesive points are made of special resin tha provides very high tenacity and adhesiveness when treated properly. Such surfac...
