Q.    Can I install new shingles overtop of the old shingles?
A.    It is possible, but we recommend removal of the existing shingles to ensure the shingles perform to the manufacturer's specifications and to keep your manufacturer's warranty intact.  Installing new shingles over the existing can trap moisture from the old shingles and cause premature deterioration of the new shingles.

Q.    Why is ventilation so important?
A.    To prevent moisture condensation during the wet winter months and to cool your attic space in the summer.  It may also be a requirement of the shingle manufacturer.

Q.    Is it possible to install new shingles in the winter?
A.    Yes we can and do and we guarantee you a "leak free" installation.

Q.    I have just had new asphalt shingles installed.   Why are the granules coming off?
A.    This is very common with new shingles.  When manufactured an excess amount of granules is applied and these wash off. This will stop after the first few rainfalls.

Q.    How long will it take to roof my house?
A.    It takes approximately 2 - 3 days to roof the average house. 

Q.    I have moss on my roof, is there anything I can do?
A.    If the moss build-up is slight, you can leave it. If it is severe, you can apply a solution of zinc sulphate mixed with hot water. Do not pressure wash the roof.
