7 Signs that it’s Time for a New Roof
The roof is an important part of every house and home. It is through a strong roof that items in the house can be safe from draught and dampness which causes rotting in furniture, mold growth, short circuiting and even damage on carpets and other fabric made materials. Although the roof may be new, some factors may lead to its replacement with a new and effective one. Discussed below are factors and signs that will help you determine whether it is time to have the roof repaired or replaced.
1. Missing shingles
It is very easy to identify missing shingles on the roof. You may find one or two shingles having fallen off from the roof. If you find these, you then need to inspect the roof to see if there is more damage on the roof. Missing shingles means that the tar which was used to bind these shingles together is too weak. This may be due to UV breakdown and degradation. If only one or two shingles are missing, you can then call for repairs and servicing of the same. Nevertheless, if many of these shingles are loose or have fallen off, it may be time to have the house re-roofed.
2. Cracked shingles
Shingles may start to crack with time, especially if their lifetime is over. They may also start curling up and cracking due to intense heat from the sun, which degrades asphalt layers causing shrinkage. Cracked or shingles that are curling upwards can catch a gust of wind thus get blown off the roof. If this happens, you roof will be left with dents which will allow water into the house. Walking on already cracked shingles can be dangerous, as they may not be strong enough to take on any one’s weight, thus curve in causing more damage.
3. Dark spots on roof shingles
Shingles tend to wear off leaving dark visible spots from afar. This is mainly caused by the loss of granules and asphalt degradation which holds the granules together. These granules become loose and are lost over time, and can be found in gutters or break off points on the roof. This mainly happens when the roof has been exposed to the sun for a long time, or if the shingles are too old. You may have the already damaged shingles replaced, or re-roof the house as a whole.
4. Damp and discolored spots in the attic and ceiling
Damp spots in the attic means some water is leaking into the house through the roof. Although the roof may be intact, water may find its way into the house during windy rainy seasons. If this is the case, you can have a roofing technician come and waterproof the roof against this. The dampness can also be caused by missing shingles on the roof, meaning it is already compromised. A roofing technician can inspect the house to determine the level of damage, and then advise you on the best solution on the same.
5. Excessive moss growth on the roof
Although your roof may not show any signs of allowing water in, excess most growth on the same is a disaster waiting to happen. As moss grows, it continues to decompose on the roof, creating more dampness and weight on the roof. Moreover, moss roots easily find way through shingle bridges, which then start tearing the shingles apart, as well as decomposing the roofing material. Moss can be cleaned up when noticed in good time.
If the moss has been growing unnoticed for some time, it may then be dangerous to climb up to remove it. The only way to deal with this is have roofing technicians assess the roof, take it down, and re-roof afresh. A biodegradable moss control method can be used to keep moss growth at bay.
6. An already aged roof
If the roof has been standing on the house for a long time, and its lifetime has expired but still shows no signs of leakages, you can consider having it replaced. If the roof was meant to serve you for 20 years, but has been standing there for more than 35 years, it then means that the materials are already weak and may curve in anytime. You can have a roofing specialist advise you on the best and recommended roofing materials to replace the already old roof.
7. Rusty iron sheets
Iron sheets rust with time no matter how much oil based oils you paint on them. Rusting is mostly rampant in areas of high humidity and temperatures. When the roof starts showing any signs of rusting, or turning to a golden brown color, it is then time to fetch another roofing material for your home. As long as it has started to rust, its strength is already compromised and may start leaking at any time. This thus calls for new roofing materials to make the house habitable for many more years.
