Roof Replacement Vs Roofing Repairs:
There is a saying in the personal finance world that when it comes to our finances, each situation should be treated personally, hence the emphasis on Personal finance. The same can be said for your roof.
While there are metrics that can determine whether an entire roof replacement is more suitable for your home, or perhaps a simple repair, the best thing to do is to first start with a roof inspection.
Once you have your roof inspected by a certified roofing specialist/contractor, you should weigh your options. Its vital to weigh all of your options:
- Is there a possibility for an insurance claim?
- How old is your roof?
- Will the repair last, or is a new roof the better long term option?
- Will a roof repair cost more than just replacing the entire roof?
Typically, if it is something simple like replacing a few shingles, checking out a possible leak, or replacing a section of a ridge vent, a roofing repair is a good option.
However, when the amount of roofing shingles needing to be replaced reaches a certain threshold, or the repair costs are starting to get to 50% of the cost of a new roof, a roof replacement is usually a better option.
For example, if a new roof would cost you $7,000, but the repairs cost $3,5000, its better to simply replace the roof.
A new roof has a high return on investment for resale purposes and the new asphalt roofing shingles have amazing technology that makes it hardy and looks better!

Dealing With A Mossy Roof
Q: What, if anything, should I do about all the moss thats growing on my roof? Dorothy Plummer, Dingmans Ferry, PA.
A: Tom Silva replies: Moss holds moisture against shingles, shortening their life. It also catches debristwigs, leaves, dirtthat makes the moisture problem worse. But before removing the moss, grab a pair of binoculars and take a good look at your roof. If you see shingles with surface cracks, small blisters, curled-up edges, or areas where the surface granules have worn off, you probably need new roofing. But if the shingles are in good shape, heres how to get rid of the moss.
First, take these precautions: Spray water on all the plants under the section of the roof you will be working on or cover them with plastic tarps. The 50-50 mix of water and bleach thats used to kill moss can also kill or damage any foundation plantings it drips on. Also, because the roof will become very slippery when you spray the moss with the bleach mixture, stay off the roof and on a ladder during the entire process. An extension ladder with a roof standoff provides a secure platform.
Apply the bleach solution with a pump sprayer until the moss is saturated, then wait 15 minutes or so to rinse the roof thoroughly. If your foundation plants arent covered, rinse them, too. Now wait a week or two for the moss to dry up. If you can, get on the roof to brush it off. If not, the dead moss will eventually wash away.

Calculate The Simple Roof Areas
On a simple hip or gable roof, multiplying the eave to ridge length by eave length will give the area to be multiplied by pitch factor. Ridge vent openings are best finished with coil rather than partial shingle. Using flat coil stock allows the ridge caps to lay flat and can also be formed with an extra water stop at the ridge opening.
Area for the roof in Figure 3 is 1784 ft2 The blue dash line divides the roof into 2 rectangles. There is a small area calculated as 8/12 that is actually 4/12. On a small area such as this, it is better to err on the side of the higher pitch since it should not significantly affect the total.
Pro Tip: Pythagorean Theorem can be used to calculate the length of the valleys. A general rule of thumb is to add at least 12 lineal inches of valley material to be safe.
