Respectable Roofers

Why do I need vents or more vents adding to my house? Vents are a very important part of the roofing system, they allow the attic space to release warm air during the summer and cold air during the winter so that condensation doesn’t form. When we measure the roof it indicates to us the correct number of vents required, often newer homes have the bare minimum number of vents and sometimes the wrong kind of vents for bathrooms. What is tar/felt paper? Felt/tar paper is an asphalt saturated paper product. It’s not waterproof but very water resistant. Its purpose is to provide extra protection on lower pitched roofs or eaves protection on steeper roofs. What is ice and water shield? Ice and water shield is an asphalt product that has a sticky backing on it. It is applied to areas of the roof that need extra protection. The ice and water shield seals around the nails that penetrate it, this product gives superior protection, as it’s more like a rubber membrane underneath the shingles. It is typically only used at the roof edge, valleys, skylights and chimneys because of the cost. Can I install new shingles on top of old ones? You can install a second layer of shingles, but we don’t recommend it. It voids the warranty on your new roof and decreases the life expectancy too. Homes with 2 layers of shingles tend to need more plywood replacement due to rot when re-roofing at a later date. Why is my quote different to my neighbours but our houses are a similar size inside? There are several factors which determine the cost of a job. The pitch of the roof will make the biggest difference, it will probably cost more as it will need more material and it’s much slower for the roofers because of the danger involved in moving around on the steeper pitch.
