Why does my roof have streaking?
Roofs can begin to show streaking or discolouration roughly five years after being installed. These dark streaks often appear on the northern slope of the roof, and can often look like granule loss from shingles, or even just dirt. The streaking is often caused by the growth of moss and algae, which happens on areas of the roof that receive less sunlight.
Because shady sections of your roof hold moisture for a longer time than bright sunny patches, moss and algae can grow. This discolouration is often nothing to worry about, as it does not affect the life of your roof or any of its waterproofing. It is often just a visual issue for residential roofing. If you’re still concerned, check out some of our warning signs that it’s time for repairs or a new roof.
Why is one side of my roof wearing away faster than the others?
A roof will wear away faster and experience different conditions based on its exposure to sunlight and the elements. The south-facing slope of your roof will often wear away a bit faster than the others, as it receives the most sun. Sun exposure can result in UV rays breaking down your roof material.
Can I install my new roof over old shingles?
We don’t recommend it.
Installing a new roof over old shingles can cause problems. Unusual shapes can form, and your new roof will not be level. As well, leaving old shingles on when installing new residential roofing can lead to rot. It will not be possible to do an inspection on the deck sheathing for any rot or deterioration, which means your new roof will be starting its life with a variety of problems.
Having two layers of roofing can also trap moisture and raise temperatures, meaning your roof will age faster.
Putting new shingles over top of old shingles can work if the old shingles are in good condition. If this is the route you’d like to take, we recommend an inspection to make sure everything will work out.
When is time to repair or replace my roof?
A number of factors come into play when deciding to repair or replace your roof. Age, deterioration, and distorting can all mean it’s time for some new residential roofing. Check out some of the warning signs and factors or contact us for an inspection.
What type of shingle would be the best for my roof?
Unfortunately, this question doesn’t have an easy answer. There are over sixty types of shingles that can be applied to a roof, and the right type of shingle varies based on many different factors. The best option is to have a professional evaluation of your roof (a service we provide). We can tell you what the best option is for your home, needs, and budget.
Do I need vents? What do they do?
We recommend it! Simply put, vents circulate the air in your attic. This can improve the life and quality of your residential roofing. It will reduce moisture and condensation and help the plywood breathe.
