"Have listened to you for years. I HAVE AN IMPORTANT QUESTION. A membrane roof has a longer guarantee 20 years, the material looks unimpressive, what is it's longevity beyond that? An asphalt roof has a 10 year guarantee but with good maintenance can last 3 times longer. My old roof is at least 4...
Barbara in Montreal had water damage in her bay window area as wind driven rain always found it's way in. Contractor repair bids ranged from $1,200 for a patch to $4,000 for a new roof. A study of the detail where the added-on bay window joined the very edge of the roof showed a flashing flaw tha...

Yes it is a problem Lorne, except for roofs in some desert areas where evaporating water is part of the air conditioning design, and the roof is specially designed like a swimming pool. For the rest of us, standing water will lead to a premature ageing of the roofing material, whatever material i...
The question is: Can you put new asphalt roof shingles right over old ones.
If the old ones are flat and you fill in any missing tabs, and you do no more that a total of two layers of shingles, yes you can reshingle over old shingles. The major question point would be to check out if your old...
