Signs You need to Replace Your Roof
When it comes to repairing or replacing a roof, what are the signs a roof needs replacing?
Some signs that a roof absolutely needs replacing are as follows:
- Shingles curling, missing and cracking. Once a shingle reaches the end of its usable lifespan they will begin to become brittle, making it very difficult to repair.
- Leaks on roofs that have multiple layers. Pinpointing the problem, finding the problem and replacing rotted wood on a roof with 2 or 3 layers of shingles is almost impossible in many circumstances. At this point, we would recommend a new roof.
- Have you ever seen black stains and streaks on the surface of the roof? These stains can be mold, fungus or algae. This happens due to moisture and poor attic ventilation. While it’s possible to scrub the roof and get clean it off, we recommend redoing the roof so the attic can vent properly and the mold, fungus, and algae don’t return.
- Another big factor is the age of the roof. Check your records. If your roof age is close to the normal lifespan of the shingle installed it probably isn’t cost effective to repair the roof when it will need to be replaced soon anyway.
Signs a Roof Can be Repaired Rather Than Replaced
Roof damage comes in several different fashions. Sometimes there is simply only aesthetic damage such as a shingle being dislodged, or hail hitting the shingles. Other times everything can look fine but there will be leaks. A repairable roof leak will generally happen in a few common areas such as flashing details, roof transitions, exposed nail(s) and at eaves. If the roof only has a single layer of roofing, and the shingles are not brittle, repairs can usually be done with no problems.
What are the general lifespans of roofing materials?
The most common roofing materials are asphalt, wood, and slate. The lifespans of asphalt roof shingles can range from twenty to fifty years depending on the shingle, weather conditions and most importantly if the roof has a proper attic ventilation. The average lifespan of a wood shake roof shingle can range from 30 to 40 years pending the grade of cedar and ventilation. Slate roofs expected life spans will range from 50 to 75 years also pending on the grade of the slate. Slate will often outlive the underlayment that it has been installed over, causing it to be replaced sometimes before the slate is worn.
With any kind of roof system, the way it is installed is just as or even more important than the type of material being used. Using the proper underlayment, having balanced attic ventilation, properly installed flashing details and installation of the shingles to its manufacturer’s specifications are all very important to the longevity of the roof.
Do flat roofs wear more quickly than flat roofs?
Flat roofing types such as SBS, self-adhered and EPDM generally will not last as long as a shingle roof will. These roofs are a rubber based product that will have standing water on them which accelerates wear. Most flat roofs should last about 15 years if installed properly.
However, one newer innovation in flat roofing is silicone roof systems. These roof coatings are revolutionizing the way commercial flat roofing is done by simplifying the installation of a new roof, and being made of a material that can last up to 50 years when installed by a professional.
