Can I cover over my existing roof?
Installing a new roof over the top of an existing roof is generally acceptable under these guidelines: 1) A building can not have more than two roofs: 2) No wet insulation can be left in place: 3) the roof structure must be able to handle the additional roof load: 4) the new roof must be attached to the roof deck to meet wind loads (it is not generally acceptable to adhere the new roof to the old roof).
How many roofs can I put on?
Most building codes allow a structure to have two roof membranes in place, but not a third. The codes are also now requiring all roof layers to be removed once the two roof limit has been reached, when looking to install the third roof.
When is the best time to put a new roof on?
This question could be interpreted two ways, so we will answer each question.
1) In Florida there really is no “bad time” to install a new roof. As we all know it rains periodically through the year and rainy season is always. So as a roofer we always watch the weather and pray for no rain until the underlayment is down and secure.
2) The question might be put this way: “How do I know when my roof has failed?” Different types of roofs fail in different ways.
Does the roof leak in numerous locations?
Do leaks continue, despite repeated repair attempts?
Do repairs seem to make leaks worse, or do new leaks develop after rain?
How tolerant is the occupancy to leaks? Low leak tolerance generally means the “failure” decision is reached earlier. It is generally better to reroof at the appropriate juncture, rather than poring money and time into ill advised repairs, but there are exceptions.
How can a homeowner recognize when a roof has problems?
All too often, roof problems are discovered after leaking or other serious damage occurs. Periodic (twice a year) inspections can often uncover cracked, warped, or missing shingles, loose seams and deteriorated flashings, excessive surface granules accumulating in the gutters or downspouts, and other visible signs of roof problems. Indoors, look for cracked paint, discolored plasterboard, and peeling wallpaper as signs of damaged roof areas.
What are my options if I decide to reroof?
You have two basic options. You can choose a complete replacement of the roof system, involving tearing off the old system, or you can do a recover over the existing roof, involving going over the existing roof. If you have already had one recover then you can not go over the existing roof.
What is the best roof?
Wouldn’t it be simple if there was one answer to all roofing problems? Unfortunately there is no magic pill in the roofing market that solves all roofing problems. What the market does offer is a wide selection of good products, each having attributes and faults. The key to selecting the proper roof system is to identify the specific roof design of your building and how each roof system works to meet the requirements.
What will a new roof cost?
The price of a new roof all depends on the type of material you select, weather you are removing the old roof or not, the type of underlayment, the price of the permit and so on. Make sure that you get at least three estimate if you believe that the cost is high. However, be sure that if one person comes in higher than the other that you ask the right questions about the type of material being used and the reputation of the company, just because it is cheaper does not mean that it is better. Sometimes the higher priced contractor is the one you want to go with because of their reputation as a well known contractor and because of the quality of the material they are using.
